How to Fusion Splice Fiber Optic Cable
Fiber optic splicing products are used to make a perfect melting of the bare optical fiber together. It refer to the combining of two lengths of cables to create one longer cable. You may need to splice fiber optic cables for reasons like combining shorter cables, replacing broken cables or connecting intermediate points between a transmitter and receiver. Fusion splicing and mechanical splicing are two methods for splicing fiber together. Fusion splicing is the most usually used method to splicing large fiber counts and for permanent fiber connections. Here we will discuss the steps for fusion splice fiber optic cables.
1. Fiber Preparation
Prepare the fiber by taking off the outside sheath of the fiber optic cable, cutting the aramid strength member, and then stripping away the buffer layer from the fiber with fiber stripper.
In this step, you nee to make sure a clean environment for the bare fiber, no filling gel or finger touching are allowed to affect the refraction index of the cable.
2. Fiber Cleaving
After prepared the fibers, you need to make the end of the fibers cut squarely by cleaving the fibers. A good quality fiber cleaver is essential in this step, which will release less light loss and reflection problems by producing a fibre end that is clean and flat with no hackle. Place the prepared fiber into the groove on the fiber optic cleaver, clamp the cables in place, close the lid and then press the cleaving lever to complete the cleaving process.
3. Fusing Splicing
Put the fibers into the place in the fusion splicer, bring the end of fibers close together and pressing start on the fusing splicing machine. You will be reminded the process is complete.
4. Splice Protection
Once the splice has been completed, take the spliced fibers out of the fusion splice and put on the heat shrink protector (tube) over the joint where the fibers are spliced. Put the spliced fibers (with protector tube) into the heat shrink oven and allow the oven to shrink the tube around the splice point.

FTTH ODN Network Construction
FTTH (Fiber to The Home) is an optical fiber communication transmission method. The optical fiber is directly connected to the user's home (user required). Specifically, FTTH is to install the optical network unit (ONU) in a domestic user or enterprise users, it is a typical optical access network application type except for FTTD (Fibe to the Desk).
ODN (Optical Distribution Network) is fiber optic cable network based on PON FTTH. It is to provide the optical transmission channel between the OLT and ONU, and consist of all the passive optical fiber, passive components between the OLT and ONU.
ODN plays an important part in the whole FTTX network. It is the optical transmission channel linking the FTTH network between OLT and ONU. The mainly equipments includes fiber optic cable, fiber optic connector, fiber termination box, fiber splitter and more. The object of ODN construction is to realize economical, practical, flexible and reliable network coverage based on different scenarios, mainly to mainly to solve the selection of OLT and ONU location, spectroscopic methods, the mode and layout of optical fiber and cable, as well as the optical cable splice into the side and other related problems.
The ODN network equipment investment account for 23.8% of the entire FTTX network engineering, construction investment account for 27.2%, that is to say, the ODN network occupies the FTTX overall investment CAPEX 51%. Visible, ODN has become the key to the construction of FTTH network. The huge ODN construction has become a major challenge faced by the operators.
FAQs for ODN Construction
Why using optical path to test with OTDR will lead to OLT dropped?
In order to maintain the link between the OLT and the ONU, among which has similar heartbeat mechanism. Uplink light source intensity is too large to achieve maximum acceptance of the OLT, the OLT end accept is protected, or saturation, result in the OLT receives less than ONU sending the heartbeat to respond, and dropped.

What is the specific meaning of delay compensation and ranging?
When the OLT detected the ONU under the port of PON, it will measure the distance and obtain the delay of every ONU. After that, take other ONU to delay compensate to the maximum delay to get the maximum value, in this way, all the ONU will get the same distance.

PON, ODN, how to get the fault location fast and with the lowest cost?
Based on the SLA set of standard, fast and efficient positioning is bound to be costly. At present, the off-line testing is the Lowest-cost detection technology.

Can we spectroscopically mix the first and two class of FTTH ODN?
ODN in PON system (splitter and fiber) is a passive part, OLT and ONU is no perception of the specific structure of the ODN. ONU under different branches share equal status, only exist difference between the signal attenuation and delay.

How many ONU is a port of OLT connected to?
From the system point of view, you need to consider the uplink and downlink bandwidth on the OLT, the mac address learning number of OLT (lsw, fpga), of course, the hosted user bandwidth is also a factor to consider for a particular bandwidth applications.

What’s the impact of the upper and lower limit of the OLT and ONU optical power to the EPON transmission?
If the received optical power is greater than the upper limit of the optical module, it is likely to be burned out the module, if it is below the lower limit of the optical transceiver module, the OLT will find not ONU equipment. Besides, the optical module is with transmission distance limit, beyond the limited distance will result in failing to find the ONU.

Steps for Fiber Optic Cable Termination
Fiber optic cabling is a important aspect of local area networking（LAN）communications infrastructures. fiber optic cables are being used in an increasing number of applications, especially in networking and cable/ Internet. In fiber networking installations, workmanship is critical to reach acceptable results because even a small imperfection or microscopic dirt on the face of the fiber can result in significant problems with optical propagation, which can cause the link to fail. This article offers a hands-on tutorial for fast, safely, and correctly creating fiber optic connections that meet good standards of quality workmanship and ensure optimal coupling efficiency. The following steps for fiber optic cable termination with epoxy will help installer avoid problems by providing a solid base of information that will have great reference value for both new and experienced field technicians terminating fiber optic cables often.
Step1. Creating and maintaining a safe work environment.
You should not only protect yourself during the installation process, you also need to leave the installation area in a safe condition for other people beside you. Fundamental safety tools include a dark work surface, such as a black work-mat, and a proper trash receptacle for fiber scraps that is clearly marked as to its contents. Using a piece of black tape to stick your scraps on isn't an acceptable work practice other than just incorrectly flick off the cleaved fiber scraps with fingers which could be harmful to the occupants nearby. Then, use a microscope to check a fiber to make sure the other end isn’t connected to a power source since the invisible laser light is harmful to the eyes while you may not eve realize you’re looking into it until it’s tool late..
Step2. Strip the cable with a fiber cable stripper.
Once you have your bulk fiber cable, strip the cable down to the bare fiber using an appropriate fiber stripper such as the Fiber Cable Stripper. After you have prepared the end of the cable you may begin to mix the epoxy resin and hardener together and load it into a syringe, unless of course you are using pre-loaded epoxy syringes, which are premixed and kept frozen until use. Now, from the syringe you must inject the epoxy directly into the connector ferrule.
Step 3. Inject epoxy into the connector ferrule and insert the fiber optic into the connector wall.
Injet epoxy into the fiber optic connector ferrule and then insert the fiber optic cable so that the cable is seated inside of the connector wall and the bare fiber core sticks out about a half an inch from the front of the ferrule.
Step 4: Crimp the cable with the cable crimper.
If your cable is jacketed, you will need to use a crimping tool to secure the connector to the jacket and strength member of the cable. Two crimps would be needed at this point.
Step 5: Place the cable in the curing holder, suite the connector end facing down.
After that, the next step is to place the connected end into a curing holder to ensure that the end of the fiber is not damaged while curing. Now place the cable and curing holder into a curing oven. To avoid “wicking” while curing with a conventional oven, situate the connector so that the end is facing down. This positioning will ensure that the epoxy does not come out of the back side of the connector and compromise the strength member of the cable. Then you need to refer to the documentation of your specific epoxy for accurate curing times and temperatures.
Step 6: Cleave the fiber with the fiber optic cleaver. Get as close to the ferrule tip as you can.
After you have sufficiently cured the epoxy, you are now ready to move on to the next step, cleaving the excess protruding fiber core. Tool you need is a Fiber Optic Cleaver. Get as close to the ferrule tip as possible while avoiding any sort of twisting motion.
Step 7. Dispose of all fiber pieces after cleaving.
Once cleaved, it is important that you properly dispose of the fiber clipping. A regular piece of tape will do just fine at retaining your fiber debris. If you do not properly dispose of all fiber pieces they could easily end up in your skin or even in somebody’s eye or respiratory system. A short strand of fiber can cause more damage than you would at first imagine.
Step 8. Polish the end of the fiber optic cable.
After the excess fiber cleaved and properly disposed of, you can begin the task of polishing the fiber tip to a smooth finish. Using fiber optic polishing tool you can effectively remove any excess epoxy from the ferrule end and buff out any imperfections on the face of the fiber. You can polish the cable tip with the 5-15 micron film, 5 micron aluminum oxide film, 3-6 micron diamond film, 1 micron diamond film, and HX film in order. A smooth fiber surface makes great sense to any light passing through.
Step 9. Clean the ferule and fiber tip.
If you have finished with your polished finish, you can move on to the cleaning of the ferrule and fiber tip. Using a lint-free wipe dipped in 99% reagent-grade alcohol, gently wipe the surface area of the ferrule and fiber tip and immediately wipe them dry with another dry lint-free wipe. You may optionally use a can of compressed air to finish the process.
Step 10. Test the terminated cable with fiber optic test equipment.
Now the connected cable is complete. The last step is to ensure good standard. First you need to inspect the fiber tip with a 100x to 200x microscope. And then test your cable with a fiber optic test equipment for insertion loss and return loss where needed.

What is Low Smoke Zero Halogen & LSZH Cable?
What exactly LSZH is?
Low Smoke Zero Halogen cable can be called LSF (low smoke and fume), LSHF (low smoke halogen free), and LS0H (low smoke zero halogen). LSZH cable, which is short for Low smoke zero halogen cable, refer to using compounds in the cable jacking manufacturing process that are halogen free and flame retardant. This type of jacket material has excellent fire safety characteristics of low smoke, low toxicity and low corrosion. LSZH cable is widely used in applications where people are present in poorly ventilated or confined spaces, like airplanes, rail cars, or offshore marine platforms.
Features of LSZH cable:
Halogen Free
Materials that contain halogens emit potentially harmful gases like chlorine, fluorine and bromine when burned, that makes halogens the main concern for the wire and cable industry. Harmful gases emit by halogen material are extremely damaging to the human respiratory system and can even corroded nearby equipment. PVC wire and cable has a huge amount of halogens in it. However, Halogen free cables, like LSZH cables, is mad up of a compound called polypropylene, will not produce a toxic gases during combustion.
Low Smoke
As we know, smoke inhalation is the main cause of death related to fires. Smoke inhalation occurs when products of combustion are breath in during a fire. Damages to the body are by simple asphyxiation (lack of oxygen), chemical irritation, chemical asphyxiation or a combination of all these. Because LSZH cables are low-smoke, people can make a quicker and easier escape in the event of a fire. There is far less smoke to limit their ability to see and breathe, allowing them to get out with less trouble.
Easy Jacket Cracking
Although LSZH cables have some important benefits, there is a still a shortcoming – easy jacket creaking. A qualified LSZH cable must have a high percentage of filler material. This means that the jacket will likely be less chemical and water-resistant and have poorer mechanical and electrical properties than a non-LSZH cable jackets. This makes LSZH cable more likely to experience jacket cracking during installation. However, special lubricants used for them will avoid the damage.
Pros and Cons of LSZH cable:
Pros：
1. LSZH produces less smoke when burned which allows more escape chances.
2. Less damage and less corrosion damage is done to the respiratory and nearby equipment in the fire because of little or no halogen gas released.
3. The jacket of LSZH cable has a lower coefficient of friction making installation easier.
Cons：
1. SZH is more susceptible to jacket cracking. Special lubricants are needed to minimize damage during installation.
2. LSZH jacket has a high filler content, around 50% to provide the required flame and smoke performance, which would results in a lower mechanical, chemical resistance, water absorption and electrical properties than non LSZH compounds.
3. The current generation of LSZH cables has not yet established a proven history of long time performance.

Fiber Optic Splice Closure Installation
Fiber optic splice closure is an important equipment that widely used in fiber optic telecommunication system. Specifically speaking, a fiber optic splice closure or fiber splice closure is an equipment used to offer room for fusion splicing optical fibers in outdoor fiber optic cable. A fiber splice tray is needed together to protect the fused fiber joint and fiber cables from outside plant environment including aerial, direct burial and underground/manhole installations.
There are mainly two types of fiber optic closures: vertical type and horizontal type.
Horizontal Fiber Optic Splice Closure looks like flat or cylindrical case and can be mounted aerial, direct buried or installed underground. This type provide fire resistant, waterproof and quakeproof for splices with operating temperature ranging from -40°C to +65°C and pressure up to 106kpa. The external component and fastening piece are often made from the high-quality stainless steel or high tensile construction plastic.
Vertical Fiber Optic Splice Closure or dome type fiber splice closure share the same specification with horizontal types. But the main application for vertical fiber optic splice closure is in CATV, telecommunications and fiber optic networks and mainly used for protecting optical fiber splices in straight through and branching applications.
Before show steps of fiber closure installation, we need to know the components in the fiber optic splice closure:
The following parts are usually included in a fiber optic splice closure kit: End plate, splice tray organizer, fiber splice tray (used for storing optical fibers), cover (a cylindrical plastic enclosure with corrosion resistant metal hardware), cable grommets, grommet retainer, mounting bracket and misc. hardware.

SFP transceiver VS GBIC transceiver
With the development of data communication in the modern world, optical fibers are widely used for fiber networking. Fiber optic transceiver is an important component that will make it feasible for networks to broadcast data at both short and long distances. But what's important is that how to choose the right fiber optic transceiver for switches and routers? In fact, choose the right fiber optic transceiver is entirely depend on its application purpose.
There are different types of transceivers in the market that may get you overwhelmed. Here let's review the difference between SFP transceiver versus GBIC transceiver and inspect the varies applications.
A fiber optic is a glass or plastic fiber that carries light. There are two classifications for optical fiber: single-mode (SMF) and multi-mode (MMF). SMF has small cores (about 3.5 x 10-4 incches or 9 microns in diameter) and is used for long distance communication. While MMF has larger cores (about 2.5 x 10-3 inches or 62.5 microns in diameter) and is used for distances of less than 300 m. Since SMF emit 50 times further than MMF, they often cost more.
A gigabit interface converter (GBIC) is a standard for transceivers, offering a standard, hot swappable electrical interface. The small form-factor pluggable (SFP) is a compact optical transceiver used in optical communications, which is a popular industry format supported by several fiber optic component vendors. Fiber optic transceivers are commercially available for almost all international and industrial standards, including Ethernet, Fast Ethernet, Gigabit Ethernet, 10Gbit Ethernet. Generally GBIC transceiver or Gigabit Interface Converter is used in Gigabit Ethernet and Fiber Channel to translate SX, LX, LH, and other kinds of gigabit signals into a shared format. This device calls for SC typed connector. While SFC transceiver or small hot-pluggable transceiver used for Gigabit Ethernet and Fiber Channel.
Fiber cables can be merged in combinations of 1000BASE-T, 1000BASE-SX, 1000BASE-LX/LH, 1000BASE-ZX, or 1000BASE-CWDM interfaces on a port-by-port basis. These cables also utilize various types of connectors for different applications. But GBIC transceivers and SFPs transceivers more regularly use SC and LC connectors.
Ingellen provides a various kind of Cisco compatible transceivers like Cisco SFP Transceivers, Cisco GBIC Transceivers, Cisco SFP+ Transceivers, Cisco XFP Transceivers etc. GLC-T, GLC-SX-MM, GLC-LH-SM, GLC-ZX-SM, GLC-LH40-SM some Cisco SFP transceivers available on Ingellen.com. On the other hand, WS-G5483, WS-G484, WS-G5486, and WS-G5487 and so many more are Cisco GBIC transceivers. These Cisco SFPs and Cisco GBICs have different cable types, uses, connectors, and vary in maximum distances. There are many more fiber optic products from Ingellen.com. It will definitely be enough for your choosing the correct ones for the realization of fiber network.

Generally GBIC transceiver or Gigabit Interface Converter is used in Gigabit Ethernet and Fiber Channel to translate SX, LX, LH, and other kinds of gigabit signals into a shared format. This device calls for SC typed connector. While SFC transceiver or small hot-pluggable transceiver used for Gigabit Ethernet and Fiber Channel.
Fiber cables can be merged in combinations of 1000BASE-T, 1000BASE-SX, 1000BASE-LX/LH, 1000BASE-ZX, or 1000BASE-CWDM interfaces on a port-by-port basis. These cables also utilize various types of connectors for different applications. But GBIC transceivers and SFPs transceivers more regularly use SC and LC connectors.

Top 7 Advantages of Fiber Optic Cabling
Compared with the traditional standard copper coaxial cables, fiber optic cabling is a brand new and advanced method used in modern telecommunication and data transmission networking applications.In fiber optic networking system, fiber optic cable and end equipment use light pulses to transmit data. Light resource, Fiber optic cable and optical transceiver play a leading role in the whole transmission process. Fiber optic cables are made up of transparent glass or plastic fibers which allow light to be guided from one end to the other with minimal loss. Fiber optic cabling has obvious advantages over copper cabling when it comes to transmission efficiency, capacity, material cost and even environmental friendliness. Here are the detailed top 7 advantages of fiber optic cabling versus copper cabling.
1. Great transmission capacity
Compared with traditional copper, working frequency of fiber optic is 8-9 orders of magnitude higher, which work a greater carring capacity. Fiber optic cable is capable of carrying far more data than copper. Besides, it can also carry the information for much more distances. For example, a fiber optic can easily transmit a signal as far as 80 km or more without the need for amplification.
2. More transmission efficiency
In comparison, fiber Optic cables can transmit far more information, and with a greater degree of fidelity. Fiber links offer over 1,000 times as much bandwidth over distances over 100 times further than copper. For example, downloading a 2 GB movie over a typical "Fast Ethernet" connection (100 Mbps) would take almost 22 minutes. While, downloading the same movie over GPON with fiber optic cabling, and it would only take about 2 minutes. By providing quicker access to volumes of data that will empower end-users to be more productive.
3. Energy saving and environmental friendly
The equipment used for a Gigabit Passive Optical Network (GPON) fiber optic implementation is typically about 50% more energy efficient than the traditional networking equipment found in a IDF/Telco closet. This reduction in energy consumption for the IT network also means there is a huge reduction in the amount of Greenhouse Gas emitted into the atmosphere.
4. Free of interference
Unlike electrical cables which conduct with electricity, fiber optic cables are glass-based carring light signals. This eliminates the need for grounding and makes them immune to any type of electrical interference - even lightning. Taking the advantages of resistance to interference and atmospheric conditions, outdoor fiber optic cables can be used outdoors and even in close proximity to electrical cables without concern.
5. More data secured
Except for interference-free, class fibers can also work well in roughing conditions. We know, copper cabling is sensitive to water and chemicals, class fiber optic cabling runs nearly no risk of being damaged by harsher elements. Fiber Optic cables can easily endure living environment that coaxial cable just cannot, such as being buried with soil, or in close proximity to chemicals. Besides, since it is also far more difficult to tap, fiber Optic cabling would offers extra security for the data being transmitted.
6. Easy handling and installation
Fiber optic cables are much smaller and lighter as compared to copper-based cables, which make it much easier to handle and require less time and effort to install. In addition, the carriers would never get shocked when the fiber optic cables are break as the electrical coaxial cables do. Since Fiber optic cabling transmits light and not electricity, the people handling it run no risk of injury from fire, sparking or electrocution.
7. Cost effective
With the development of fiber optic technology, fiber optic cable is no longer always thought to be too fragile or expensive to the deployed for general applications, by contract, it has becomes more easier to work with and install. With various cable metal material price rising on the present market, while optic fiber has declined and the manufacturing processes have also been improving, Which has created an important prerequisite for the quick development of optical fiber communication.
Fiber optic cabling is being deployed in buildings, campuses and offices to provide an efficient, high-speed broadband network for end users. Fiber optic network can transmit larger quantities of data with far less loss, is able to delivery signals over long distances, carries little risk of corrosion, is with great environmental features and virtually free from interference. That’s the concludes from Ingellen.com, among the worlds foremost providers of fiber optic cables, fiber cable management solutions and other fiber networking and equipment management solutions for both business and home utilizations.
