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.

Here comes the concise guide on how to install Fiber Optic Splice Closure.
1. Fiber Cable Sheath Preparation
Expose the rip cord. Mark the location with a tape marker, ring-cut the outer jacket with a sharp knife, remove the corrugated armor if applicable, and then shave off the outer jacket to expose the rip cord.
Remove the outer sheath. By making a longitudinal slit down the outer sheath, peeling off the outer jacket and corrugated metal, and cutting the rip cord flush with the end of the corrugated metal. Remove the inner jacket. Use the rip cord under the inner jacket to slit it, cutting aramid yarns, cutting central strength member, and cleaning the filling compound.
2. Bonding and Grounding Hardware Installation
This step involves sliding the cable clamp over sheath, sliding the bond shoe under the corrugated metal, placing the bond plate over the bond shoe and securing the sheath grip.
3. Assembly of Cables to Closure
A fiber optic splice closure is usually designed for two cables in each of its two ports. Preferable location for the two main cables is in the lower end plate port. Third or fourth cable is to install in the upper end plate port as a branch cable.
Install Cables to End Plate. This step involves unscrewing knob and removing grommet retainer, positioning the end plate assembly, attaching the sheath grip to dielectric cables, sliding cables and sheath grip through, and securing sheath grip to backbone.
Install Cables to End Plate. This step involves unscrewing knob and removing grommet retainer, positioning the end plate assembly, attaching the sheath grip to dielectric cables, sliding cables and sheath grip through, and securing sheath grip to backbone.
Fiber Unit Preparation and Distribution Organizer installation.This step involves removing more loose tubes, separating each cable's loose tube into two groups, positioning the distribution organizer, securing the loose tubes to the distribution organizer, and securing the loose tubes.
Splice Tray Installation. This step involves placing the splice tray, fastening the end of the splice tray to the organizer, and installing cables, grommets and external ground. Optical Fiber Splicing. This step involves splicing holder placing, fiber splicing and fastening the splice holder lid.
4. Fiber Optic Splice Closure Cover Installation
In this step, you need to clean the grooves in the cover, slide the closure assembly into the cover, rotate the cover until the key aligns with the end plate notch, seat the cover and secure the five latches. Additionally, test the flash pressure if it is required.
5. Closure Mounting
In this step, Mounting Bracket Kit and Mounting Bracket Kit are available for mounting the closure. The closure should be completely assembled before performing any mounting procedure.
6. Reentry
Before reassembling the closure, following jobs are needed: Clean the closure surface to remove dirt and debris, orient the closure such that residual debris will not fall into the splice tray when the cover is removed, unfasten the five latches, slide the closure cover off and then set the O-ring aside for cleaning before reassembly and finish other necessary work done.

Here is the brief introduction on what’s fiber optic slice closure, types of fiber optic closure, and how to terminate it. Generally, fiber optic closure can divided in to different types according to the number of inlet/outlet ports and the fitting fiber optic core numbers. Both vertical type and horizontal fiber optic slice closure comes in 1inlet/outlet ports, 2inlet/outlet ports, 3inlet/outlet ports types, together with 12, 24, 36, 48, 72 fiber optic cores.

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.
