Cisco SFP and SFP+ Transceiver Modules Installation Guide

Cisco is one of the worldwide major fiber optic network equipments provider, the networking engineers may time and again facing the problems of install fiber optic transceivers to other Cisco devices for optical signal transmission. This article provides the installation instructions for Cisco small-factor pluggable (SFP) and SFP+ transceiver modules. These modules are hot-swappable input/output (I/O) devices that plug into 100Base, 1000Base and 10Gbase ports, to connect the module ports with the fiber optic or copper network.

Cisco SFP+ transceiver modules installation is the combination of Cisco original SFP+ or compatible Cisco SFP+ transceiver modules with your Cisco devices. Each port must match the wavelength specifications on the other end of the cable and that the cable must not exceed the stipulated cable length for reliable communications. Using only Cisco or compatible Cisco SFP+ transceiver modules on your own Cisco devices, as it allows a Cisco switch or router to identify and validate that the transceiver modules is certified and tested by Cisco.

Take SFP module for example, let’s discuss the installation guid and note.
To begin the installation, tools you need is listed below:
Wrist strap or other personal grounding device to prevent ESO occurrences
Antistatic mat or antistatic foam to set the transceiver on
Fiber optic end-face cleaning tools and inspection equipment.

SFP transceiver module have three types of latching devices to secure an SFP transceiver module in a port socket: mylar tab latch, actuator button latch, bail clasp latch. Knowing which type of latch your SFP transceiver module uses is crucial before the installation.

Disconnect all fiber optic cables before the installation
Attache an ESD-preventive wrist strap to your wrist and to the ESD ground connector or a bare metal surface on your chassis.
Removing the SFP transceiver module from its protective packaging.
Check the label on the SFP transceiver module body to verify that you have the correct model for your network.
Find the send (TX) and receive (RX) markings that identify the top side of the SFP transceiver module.
Position the SFP transceiver module in front of the socket opening. Different Cisco devices have different SFP module socket configurations. Your Cisco device could have either a latch-up or a latch-down orientation. Ensure that you are installing the SFP transceiver module in the correct orientation for your Cisco device.
Insert the SFP module into the socket until you feel the connector latch into place.
Press the SFP into the slot firmly with your thumb to ensure that the transceiver is properly latched in the socket.

After the installation steps above, the verification is needed. Grasp the SFP and try to remove it without releasing the latch. If the SFP can not be removed, it is installed and seated properly. If the SFP can be removed, you need to re-insert it and press harder with our thumb, repeat it until it is latched securely into the socket.

OM4 Optical Fiber Cabling

OM4 is a laser-optimized, high bandwidth 50um multimode fiber, which is used for next-generation 40 and 100 Gb/s applications. OM4 effectively provides an additional layer of performance that supports these applications at longer distances, thereby limiting the number of installations that truly require OS2 single mode fiber.

OM1, OM2, OM3, OM4 are different categories of graded-index multimode fiber optic cable. OM4 is not necessarily designed to replace for OM3. Despite the relatively long-standing availability of OM4. In most systems, both OM3 and OM4 are sufficient to cover the bandwidth needs at the distances of the current installation base. Despite the availability of OM4 glass, OM3 is quite capable of 40 and 100 Gb/s applications albeit at significantly shorter distances than OM4. The primary benefit of OM4 is the additional reach at extended bandwidth at an overall cost still less than that of an OS2 single mode system.

OM4 provides an opportunity to future-proof cabling infrastructure. It is completely backwards-compatible with existing OM3 systems. OM3 and OM4 are two grades of glass that can be inerchangeable within the transmission distance limitations. The additional bandwidth and lower attenuation of OM4 provide additional insertion loss margin. While the additional bandwidth and lower attenuation of OM4 provide additional insertion loss margin. OM4 users gain additional safety margin to help compensate for less-than-ideal cabling installations as well as provide margin for degradation due to moves, adds, and changes over the life of the installation.

FiberStore provide complete range of OM3 OM4 products, what is typical is the OM3 OM4 10G fiber cables, which are ideal for using in many applications such as Local Area Networks (LAN) backbones, Storage Area Networks (SAN), Data Centers and Central Offices. ( click to check out the om3 vs om4 fiber pricing). Another is the OM3, OM4 patch cables. And for 10G OM3 50/125 Mulitmode Fiber Patch

Cable and 10G OM4 50/125 Mulitmode Fiber Patch Cable, their main difference are as following:
OM4 was developed specifically for VSCEL laser transmission and allows 10Gig/s link distance up to 550 meters. The effective modal bandwidth for OM4 is more than double that of OM3. For OM4 patch cable, it is 4700 MHz km while for OM3, it is 2000 MHz km.

We can custom the 10G OM3 and OM4 fiber cables with any connectors such as LC-LC, LC-SC, SC-SC, FC, MTRJ, MU, MPO/MTP etc and any cut lengths. For example, the OM4 50/125 ST-ST connectors patch cable can be customized with both simplex or duplex fibers. Of cause you can also custom the OM3 OM4 fiber patch cable with different connector type of cable length.

Using Fiber Terminators to Terminator Unused Fiber Connector Ports

With the rapid deployment of high speed fiber multiplexer, the possibility of having an un-terminated derived channel or branch increases. The single fiber connector mated to an unused adapter or coupling is the source of back-reflection. The fiber optic terminator is usually used to terminate the unused fiber connector ports in fiber optic systems. Such unused ports will create unwanted return loss and degrade the whole network performance. Fiber optic terminators are passive components that can absorb light coming from the unterminated connectors plugs and reduce signal degradation in digital and analog systems.

optical terminators from FiberStore

Fiber optic terminators are designed to reduce back-reflections, which is typically found on laser-activated, connectorized access points such as those found on splitters, DWDM’s or fiber distribution frames. are functional devices using Metal-Ion Doped Fibers. By using these fibers, optical terminators can convert the optical power into heat and the power is attenuated inside the devices. The structures of the plug type optical terminators are simple and the power-proof and performance stability is superior. The fiber optic terminators also maintain the cleanliness of unterminated plugs and protect them from possible physical damage.

The plug type optical terminators are used to terminate dark fiber port on the fiber optic component.

POE Fiber Media Converters Introduction

POE (Power over Ethernet) products including the 10/100M PoE media converters, 10/100/1000M Gigabit PoE media converters, POE Switches. This full line of features rich Power-over-Ethernet media converters transparently connect copper to fiber while providing power over Ethernet to standard based POE compliant devices such as IP cameras, VoIP phones and wireless access points. These solutions take PoE beyond the 100 meters distance that has traditionally limited power over Ethernet installations.

PoE media converters combine ower and data on one cable, and connects to a network devices through an RJ45 port that injects the power from power sourcing equipment such as a PoE switch or midspan PoE injhectors. The PoE media converters provides a flexible and convenient means of powering devices that are located in our-of-the-way locations, and saving money by eliminating the expense and difficulty of direct electrical wiring.

PoE Ethernet to Fiber Converters provide an economical path to extend the distance of an existing copper network with fiber cabling. According to the TIA/EIA 568-5-A standard for category 5e cable, the maximum length for a cable segment is 100 meter, and PoE power injector do not increase the distance of the date link. To overcome the distance and bandwidth limitation of UTP cabling, fiber optic cabling is the best solutions, by using the POE media converters, the fiber is converts to copper and sends DC power to the PoE compliant devices over the UTP cabling.

How POE Media Converter Work
PoE schematic that appears at right (view a larger version here), an Ethernet switch with RJ45 snagless connector port resides in a control room or data closet. The copper UTP cabling is converted to fiber with a standard media converter. The fiber is run a long distance to the PoE media converter located near a convenient AC or DC power source, where it converts the fiber back to copper UTP. The PoE media converter also functions as a power-sourcing mini switch, and injects PoE (DC power) over the UTP cable. At the other end of the UTP cable is the IP camera, located up to 100 meters away from the PoE media converter.

FiberStore PoE media converter combines data received over a fiber optic link with48VDC power; providing power to Data Terminal Equipment (DTE) Power Devices (PD)over unshielded twisted pair cable. The PoE converter is a Power Sourcing Equipment (PSE) and is fully compatible with Powered Devices (PD) that comply with the IEEE802.3af: 2003 standard. The converter also includes a PD signature sensing and power monitoring features per the IEEE 802.3af standard.

FiberStore supplies a vast range of network players to solve the customers'demand for fiber media converters. Our media converters series includes but not limited by 10/100/1000Base Ethernet Fiber Media Converters, 1000Base Gigabit Fiber Media Converter, SFP Fiber Media Converter, Industrial managed Media Converter, Managed Media Converter (Standalone or Card Type), POE media Converter, with options in singlemode dual fiber, multimode dual fiber and singlemode single fiber. We also supply Media Converters Chassis, like 14 slot media converter chassis, 16 slot media converter chassis, and 17 slot media converter chassis, used to manage the various media converters.

CWDM System Testing Process

With the explosion of CWDM, it is very necessary to formulate a basic testing procedure to certifying and troubleshooting CWDM networks during installation and maintenance. Today, one of the most commonly available test methods is the use of an OTDR or power source and meter, which is capable of testing the most commonly wavelengths, 1310, 1490, 1550 and 1625nm.

This article here is based on the pre-connectorized plug and play CWDM systems that allow for connecting to test equipment in the field:

In the multiplexing module of a pre-connectorized CWDM system, wavelengths are added to the network through the filters and transmitted through the common port. The transmitted wavelengths enter the COM port in the de-multiplexing module and are dropped. All other wavelengths present at the MUX/DeMux module are went through the express port.

Most of today's OTDRs have expanded capability for testing wavelengths in addition to 1310 and 1550 nm. The OTDR allows partial testing of such system offered in test equipment source. The OTDR allows partial testing of these systems by using the flexibility of pre-connectorized solutions. This is done by switching connections within the CWDM field terminal to allow for testing portions of the non-1310/1550 nm optical paths.

To test the 1310nm, the first step is to test the downstream portion of a system at 1310 nm by connecting the OTDR to the 1310 nm input on the CWDM MUX located at the headend. Then switch the test leads over the the upstream side and repeat. Test method is the same for both the downstream and upstream paths.

1550 nm testing is performed similarly by switching the test leads to the 1550nm ports. If additional wavelengths are present, you need to follow the procedures below:

Using the 1550 nm test wavelength, switch the OTDR connection to the 1550 nm input port on the headend MUX. Have a technician stationed at the field terminal connect the drop cable leg connectors for the 1570 nm customer to the 1550 nm port on the Mux/demux device. What should be noted is that in a play and plug solution this should not require repositioning where the drop cable passes through the OSP terminal. Test the downstream 1570 nm passive link at 1550 nm, and then repeat for the 1570 nm upstream side. When testing is complete, have the technician switch the connections for the 1570 nm drop back to the 1570 nm ports on the field MUX/DeMUX device as shown in Figure 6. Repeat this process for the 1590 nm, 1610 nm drop cables and other wavelengths present. Finally, test the 1550 nm path normally with the 1550 nm drop cable connected to the 1550nm MUX/DeMUX ports.

Since the OTDRs is able to test at 1490 or 1625 nm, the drop cables under test could be connected to the EXP port of the module and tested at 1490 or 1625 nm respective wavelength, without having to connect each to the 1550 nm port. Otherwise the procedure is the same.

As CWDM network become more and more common the data they carrying has also become critical. The procedure introduced here allows for testing modular pre-connectorized CWDM systems with standard optical test equipments. Relative channel power can be measured with a wide-band fiber optic power meter at the filter outputs or at other points in the network with the aid of a wavelength selective test device or with an optical spectrum analyzer.

Defferience between Active and Passive Twinax SFP+ Cable

Twinax cable is a type of cable similar to coaxial cable. The difference is that there are two inner conductors other than on in coaxial cable. This kind of cable is commonly used for very short range high speed differential signaling applications.

Currently there is a copper 10 Gigabit Ethernet cables which comes in either an active or passive Twinax cable assembly and connects directly into an SFP+ housing. SFP+ cable is a twinax cable with SFP+ connector at each end. An active twinax cable has active electronic components in the SFP+ housing to improve the 10 Gig Ethernet signals quality. A passive SFP+ twinax cable is just a direct attach cable and contains no active components to boost signal.

SFP+ Direct Attach Passive Copper cable is suitable for very short distances. They are rated for a range up to 5m and provide a good working solution at a great cost. When the distance between connection points exceed 5m. It is highly recommended to use active cable to ensure signals are transmit all the way through. 5m as the boundary is not absolute, as it may vary from vendor to vendor. For example, FiberStore 10G SFP+ passive cable can be the optimum solution for 10G Ethernet reaches up to 12M.

Except the transmission length, there is indeed no visual difference between active and copper SFP+ twinax cable. SFP+ connectors are the same and the cable jackets are also identical. Most manufactures including FiberStore will have some sort of marking on the cable connector head which will identify the cable as active or passive. But it is also not simply to tell by just looking at it.

The major applications of SFP+ twinax cable are working with network hardware with SFP+ slot. Fiberscope SFP+ cables can be compatible with major brands such as Cisco, HPL, Juniper, Extreme, H3C etc. This type of connection is able to transmit at 10 Gigabit/second full duplex speeds over 12 meter distances. What’s more, this setup also offers 15 to 25 times lower transceiver latency than current 10GBASE-T Cat6/CAT6a/Cat7 cabling systems.

CWDM Technology VS DWDM Technology

WDM is a technology that is achieved using a multiplexer to combine wavelengths traveling through different fibers into a single fiber. The space between the individual wavelengths transmitted through the same fiber are the basis for differentiating the CWDM and DWDM.

CWDM- Coarse wavelength division multiplexing. WDM systems with fewer than eight active wavelengths per fiber. DWDM - Dense wavelength division multiplexing. WDM systems with more than eight active wavelengths per fiber.

CWDM is defined by wavelengths. DWDM is defined in terms of frequencies. DWDM's tighter wavelength spacing fit more channels onto a single fiber, but cost more to implement and operate. CWDM match the basic capacities of DWDM but at lower capacity and lower cost. CWDM enable carriers to respond flexibly to divers customers needs in metropolitan regions where fiber may be at a premium. The point and purpose of CWDM is short-range communications. It uses wide-range frequencies and spreads wavelengths far apart from each other. DWDM is designed for long-haul transmission where wavelengths are packed tightly together. Vendors have found various techniques for cramming 32, 64, or 128 wavelengths into a fiber. DWDM system is boosted by Erbium-Doped Fiber Amplifier, so that to work over thousands of kilometers for high-speed communications.

Hardware Cost
The cost difference between CWDM and DWDM systems can be attributed to hardware and operational costs. Despite the superiority in terms of cost of DWDM laser with respect to the CWDM DFB laser chilled provide cost effective solutions for long haul and metro rings large capacity demanding. In both applications, the cost of DWDM system is set off by the large number of customers who use this system. Except for encapsulation, the DWDM laser for stabilizing the temperature with a cooler and a thermistor, it is more costly than an uncooled laser coaxial CWDM.

Power Consumption
The energy requirements for DWDM are significantly higher. For example:DWDM laser temperature stabilized through coolers integrated modules encapsulation, These devices together with the associated PIN and the control circuit consumes approximately 4 W of power per wavelength monitor. However, an uncooled CWDM laser transmitter consumers about 0.5w. The transmitter of 8 channel CWDM system consume about 4W of power, while the same functionality in a DWDM system can consume up to 30W. As the number of wavelengths in DWDM systems with increased transmission speed, power and thermal management associated with them becomes a critical issue for the designers.

Because DWDM doesn't span long distance as its light signal isn't amplified, which keeps costs down but also limits maximum propagation distances. Manufacturers may cite working ranges of 50 to 80 kilometers, and by signal amplifiers to achieve 160 kilometer. CWDM supports fewer channels and that may be adequate for carrier who would like to start small but expand later when demand increases.

Bare Fiber Adapter Installation Guide

Bare fiber adapter is a typical type of fiber optic adapters that places industry standard connectors on unterminated fiber. It is contained in a durable aluminum-alloy housing which is easy to stabilize any magnetic surface for hands free use. Bare fiber adapter provides a temporary connection that eliminates the time consuming process of splicing jumpers onto individual fibers to testing, allowing users to easily test and detect fiber damages anywhere, anytime.

Bare fiber adapters enable quick and easy temporary connections of single mode and multimode fibers. These adaptors are very useful for connecting fibers to fiber optic power meter, optical time-domain reflectometers (OTDRs) and a variety of other instruments, enabling in-situ functional testing without having to attach a permanent connector.

Bare fiber adapters provide a simple and effective way to use un-terminated fibers with commercial receptacles. Here is the installation guide for the bare fiber adapters.

Attaching the patch cord
Clean connectors on fiber jumper or launch reel. Position connector on fiber jumper or launch reel with bare fiber adapter connector port. Insert the connector into the bare fiber adapter connector port until hear a click.

Preparing the fiber
Remove 6 inches of jacket and Kevlar. Remove 1 inch of coating and cladding. Cut the fiber 12mm-15mm long with fibre cleavers

Inserting the fiber
Clean the bare fiber. Press and hold down the button (There is a button on the adapter) while slowly and carefully inserting the bare fiber into the fiber port. Open the window to visually see the proper alignment of the bare fiber in the V-groove. To prevent accidental breakage of the glass fiber, slowly insert 1/8 inch to 1/4 inch of fiber at a time. Rotate the fiber until the glass aligns with the v-groove to enter the connector port. Push the fiber until it stops in the connector port After that, releaser the button to secure the fiber.

Removing the fiber
Press and hold down the button while slowly and carefully pulling the bare fiber out of the fiber port. Be sure to check for any broken glass fiber pieces after removing the bare fiber from the adapter.

Removing the jumper cable
Slowing pull the fiber jumper connector out the connector port. Broken fibers are easily removed with piano wire, allowing hundreds of insertions.

FiberStore supply the largest selection of bare fiber adapters connector styles on the market including SC, ST and FC bare fiber optic adaptor with stable qualities. These adapters use high quality ceramic ferrules and precise fiber connector housing parts, they are used to quickly and easily terminate the fiber to the equipment.
