Fiber Optical TransceiverWe usually see some products that are compliant with MSA when refers to fiber optic transceivers, but what does MSA mean? It seems like a standard that is used to define the optical transceiver. In fact, MSAs are not official standards organizations. Instead, they are agreements that equipment vendors assume when developing form factors for communications interfaces. These form factors, usually called the transceiver modules, are typically deployed in active electronics such as switches, servers and multiplexers. In this text, some knowledge of the MSA will be introduced.

What is Multi-source Agreement?

MSA stands for multi-source agreement, which is an agreement between multiple manufacturers to make products which are compatible across vendors, acting as de facto standards, establishing a competitive market for interoperable products. Products that adhere to MSAs include optical transceivers (SFP, SFP+, XENPAK, QSFP, XFP, etc), fiber optic cables, and other networking devices. MSAs strictly define the operating characteristics of these optical transceivers so that system vendors may implement ports in their devices that allow MSA compliant transceivers produced by name brand, as well a third party vendors, to function properly. That is, transceivers may be purchased from any of the multiple sources in the open market, like Fiberstore. MSAs are also important in the cabling industry as the density, line speed, power consumption and typical costs of a MSA can strongly impact its success in the marketplace. This, in turn, can drive the choice for both connector and media type.

Why is Multi-source Agreement  so Important?

Equipment vendors all rely on MSAs when designing their systems, ensuring interoperability and interchangeability between interface modules, that is every supplier can produce the transceiver modules with the same functions. For this reason, there are many module suppliers from which customers can choose freely. As we all know, freedom of choice is the foundation of the efficient operation of markets. In order to gain a bigger share of the market, suppliers may act as efficiently as possible, which may drive down costs and offer the widest options to customers. Besides, since there are so many excellent 3rd party optical transceiver module suppliers in the market that network operators don’t need to purchase optical transceivers directly from system (original brand) vendors, which will also save huge costs. Finally, there is no doubt that all these will help support and encourage creation and adherence to standards at the same time. Over the past decade, the MSA process has helped accelerate the acceptance of modules such as SFP+ and CFP, which allow optical transceivers to support greater bandwidth such as 40G and 100G.

Approved Fiber Optica Transceiver Multi-source Agreements

MSA is a popular industry format jointly developed and supported by many network component vendors, most common optical transceivers are specified by it at present. MSAs usually specify parameters for optical transceivers and their guideline values, such as the electrical and optical interfaces (e.g. SX, LX, EX, ZX, etc), mechanical dimensions, electro-magnetic values and other data. This data is accessible by the host system over the I2C interface, as is the status of the optional DDM functions. Some approved fiber optica transceiver multi-source agreements are listed in the table below:

A Complete Guide of Installing or Removing Transceiver Modules (Part II)

Monday again, welcome to my blog. This week, I will continue the topic of last week and talk about how to install or remove transceiver modules. If you have been followed my blog last week, you may be clearly know how to install or remove an SFP or a GBIC transceiver. This week, we are going to introduce the installing or removing steps of XENPAK, X2, XFP.

How to Install or Remove Transceiver Modules
3. How to Install or Remove XENPAK Transceiver Module
XENPAK Installing Steps
step 1: Firstly you should attach your ESD preventive wrist strap to your wrist to prevent ESD occurrences.
step 2: Remove the XENPAK transceiver from its protective packaging, leaving the optical bore dust plugs in place.
step 3: Verify that the XENPAK transceiver module is the correct model for the intended network.
step 4: Next, carefully align the XENPAK transceiver module with the slot on the module faceplate. You should now slide the XENPAK into this slot until the faceplate from both the module and the faceplate itself come into contact.
step 5: You can now tighten the installation screws to secure the XENPAK transceiver module.
step 6: Remove the dust plugs from the network interface cable SC connectors, ensuring that these are saved for future use.
step 7: Inspect and clean the SC connector’s fiber optic end-faces.
step 8: Remove the dust plugs from the 10-Gigabit XENPAK transceiver optical bores, ensuring that these are saved for future use.
step 9: As soon as you have removed the dust plugs you should attach the network interface cable SC connectors to the XENPAK Transceiver Module.

XENPAK Removing Steps
Please be aware that XENPAK transceiver modules are static sensitive so you should always use an ESD wrist strap or similar grounding device when coming into contact with the device. Transceiver modules can also reach high temperatures so may be too hot to be removed with bare hands.
step 1: Firstly, you should disconnect the network fiber optic cable from the 10-Gigabit XENPAK transceiver connectors, ensuring that the dust plugs are put back on for protection.
step 2: Next, unscrew the captive installation screws which secure the XENPAK.
step 3: Slide the module straight out of the XENPAK transceiver module socket, and safely put it in an antistatic bag.

4. How to Install or Remove X2 Transceiver Module
X2 Installing Steps
step 1: You must first remove the X2 Transceiver port cover from the system module faceplate. This can be done using a small flat blade screw driver. Cisco devices will often have 2 arrows on the port cover to show where to insert the screwdriver. If in doubt please consult the documents that came with your device. Once removed the port cover should be saved for later use.
step 2: Next, you should attach your ESD preventive wrist strap to your wrist to prevent ESD occurrences.
step 3: Remove the X2 transceiver module from its protective packaging.
step 4: Verify that the X2 transceiver module is the correct model for the intended network.
step 5: You can now remove the dust plug from X2 transceiver module optical port, ensuring that this is saved for later use.
step 6: Next, carefully slide the X2 transceiver module straight into the transceiver socket, located on the system’s module front panel. This will be completed once the EMI gasket flange makes contact with the system module faceplate. To ensure that the X2 is correctly inserted press firmly on the front of the X2 transceiver module.
step 7: Ensure that the module is correctly latched and seated in the module socket. Gently pull on the transceiver by holding the left and right sides of the module simultaneously, if it doesn’t move then it is correctly seated. If it does pull free then it is incorrectly seated, and you should reinsert it using slightly more force with your thumb on the front of the X2 transceiver module. Repeat the process if necessary, until correctly inserted.
step 8: You can now reattach the dust plug to the optical bore until you are ready to connect the transceiver.
step 9-a: For optical X2 Transceivers you should now remove the dust plugs from the SC connectors, clean the SC connectors fiber optic face ends, and remove the dust plugs from optical bores. As soon as this has been completed you should attach the network interface cable SC connectors to the X2 transceiver module.
step 9-b: If you are installing a CX4 X2 Transceiver you should plug the infiniBand cable connector into the CX4 X2 transceiver module connector, making sure that it is correctly aligned. You must now carefully guide the InfiniBand network cable through the cable management brackets on your system. This must be done for InfiniBand cables due to their weight, as without adequate support the cables can sag or skew. Sagging and skewing can lead to misalignment and therefore a poor connection between the cable and the CX4 X2 transceiver.

X2 Removing Steps
Please be aware that X2 transceiver modules are static sensitive so you should always use an ESD wrist strap or similar grounding device when coming into contact with the device. Transceiver modules can also reach high temperatures so may be too hot to be removed with bare hands.
step 1: Firstly, disconnect the network interface cable from the X2 transceiver module. For optical X2 transceivers you should also reattach any dust plugs.
step 2: To remove the X2 transceiver module you must lightly grip the EMI gasket flange and gently press it against the system module front panel. You should simultaneously pull the latching sleeve out in order to release the transceiver from the socket connector. The latching sleeve should only be released as you feel the transceiver unlatch.
step 3: The X2 transceiver module should now slide out of the socket straight, and be placed safely in an antistatic bag.
step 4: Replace the socket cover over the empty socket opening on your device if applicable.

5. How to Install or Remove XFP Transceiver Module
XFP Installing Steps
step 1: Firstly you should attach your ESD preventive wrist strap to your wrist to prevent ESD occurrences.
step 2: Remove the XFP transceiver from its protective packaging, leaving the optical bore dust plugs in place.
step 3: Verify that the XFP transceiver module is the correct model for the intended network.
step 4: Align the XFP transceiver module in front of the XFP socket opening, slide the module half way straight into the XFP transceiver socket.
step 5: Remove the optical bore dust plug from the XFP, ensuring that this is saved for later use.
step 6: The bail clasp should be pivoted upwards ensuring that it is parallel with the body of the XFP transceiver module.
step 7: The XFP transceiver module can now be fully inserted into the socket connector.
step 8: The Bail clasp should now be pivoted downwards, to latch the XFP transceiver module into its socket. Please ensure that the latch is fully engaged.
step 9: The optical bore dust plugs should now be reattached, until the cable is ready to be attached.
step 10: Finally, remove the dust plugs from the LC connectors, ensuring that these are saved for later use. Inspect and clean the fiber optic end faces, then remove the dust plugs from the XFP transceiver module’s optical bores. Once this is done you should attach the network interface cable LC connectors to the XFP transceiver module.

XFP Removing Steps
Please be aware that XFP transceiver modules are static sensitive so you should always use an ESD wrist strap or similar grounding device when coming into contact with the device. Transceiver modules can also reach high temperatures so may be too hot to be removed with bare hands.
step 1: Firstly, disconnect the network interface cable from the XFP transceiver module, reattaching the dust plug in the fiber optic cable LC connector.
step 2: Release the XFP transceiver module from its socket by pivoting the bail clasp.
step 3: The XFP will now slide out of its socket, ensure that you pivot the bail clasp down once it has been removed, and reinstall the dust plugs on the XFP transceiver module’s optical bores. Once removed place into an antistatic bag for protection.

Some Common Pluggable Fiber Optic Transceivers Type

There are so many transceivers in FiberStore.Such as SFP Plus transceiver, X2 transceiver, XENPAK transceiver, XFP transceiver, SFP transceiver module (Mini GBIC), GBIC transceiver and so on. But what are fiber optic transceivers do you know? Fiber optic transceiver is a short distance to long distance twisted pair electrical signals and optical signals to be interchanged Ethernet transmission media conversion unit, in many places, also known as media converter. Products are generally used in an Ethernet cable can not be covered, you must use the fiber to extend the transmission distance of the actual network environment, and is usually located in the metropolitan area of broadband access layer applications; while helping the fiber last mile connections to the metro network and more on the outer layer of the network also played a huge role.

In order to ensure the card with other manufacturers, repeaters, hubs and switches and other network equipment is fully compatible fiber optic transceiver products must strictly comply with 10Base-T, 100Base-TX, 100Base-FX, IEEE802.3 and IEEE802.3u Ethernet, etc. web standards, in addition, anti-electromagnetic radiation in the EMC aspects should meet FCC Part15. As the major carriers are efforts to build community networks, campus networks and enterprise networks, so the amount of fiber optic transceiver products are constantly improved in order to better meet the access network construction.

Now on the market most of the optical transceiver supports Pluggable, So, today I will show you some common Pluggable fiber optic transceivers type:

Some Types For GBIC Transceivers

GBIC is short for gigabit interface converter,it is a media conversion device between Gigabit Ethernet and fiber optic networks, via the GBIC transceiver, Gigabit network equipment can directly connect to copper wires, single mode fiber ports or multimode fiber ports. The data transfer rate is one gigabit per second (1 Gbps) or more.

The Cisco® Gigabit Interface Converter (GBIC) is a hot-swappable input/output device that plugs into a Gigabit Ethernet port or slot, linking the port with the network. From FiberStore, we provide a full range of Cisco GBIC transceiver modules. There are many types for GBIC transceivers, such as Cisco WS-G5483,Cisco WS-G5484,Cisco WS-G5486,Cisco WS-G5487 and so on.

Cisco WS-G5483 (Copper) GBIC module:

The Cisco WS-G5483 (1000BASE-T GBIC Transceiver) connects a GBIC port to Category 5 wiring using a standard RJ-45 interface. The maximum Category 5 wiring distance is 328 feet (100 m).Cisco WS-G5483, also called copper GBIC transceiver, is an ideal solution for Catalyst switch customers.

Cisco WS-G5484 (short wavelength) GBIC module:

The Cisco WS-G5484 GBIC (1000BASE-SX GBIC Transceiver) operates on legacy multimode fiber (MMF) optic link spans up to 1804 feet (550 m) and on laser-optimized multimode fiber (OM3) optic link spans up to 3281 feet (1 km).The 1000BASE-SX is a short wavelength GBIC module.

Cisco WS-G5486 (long wavelength/long haul) GBIC module:

The Cisco WS-G5486 (1000BASE-LX/LH GBIC Transceiver) fully complies with the IEEE 802.3z 1000BASE-LX10 standard. It allows for reaches up to 6.2 miles (10 km) over single-mode fiber (SMF) and up to 550 meters over multimode fiber (MMF). The long wavelength/long haul GBIC module is Cisco WS-G5486.

Cisco WS-G5487 (extended wavelength) GBIC module:

The Cisco WS-G5487(1000BASE-ZX GBIC Transceiver) operates on ordinary single-mode fiber optic link spans up to 43.5 miles (70 km) long. Link spans of up to 62 miles (100 km) are possible using premium single-mode fiber or dispersion shifted single-mode fiber(premium single-mode fiber has a lower attenuation per unit length than ordinary single-mode fiber; dispersion-shifted single-mode fiber has both lower attenuation and less dispersion). The GBIC provides an optical link budget of 21 dB – the precise link span length will depend on multiple factors such as fiber quality, number of splices, and connectors.

When shorter distances of single-mode fiber are used, it might be necessary to insert an in-line optical attenuator in the link to avoid overloading the receiver:

A 5-dB or 10-dB inline optical attenuator should be inserted between the fiber-optic cable plant and the receiving port on the Cisco 1000BASE-ZX GBIC at each end of the link whenever the fiber-optic cable span is less than 15.5 miles (25 km)

Note:The 1000BASE-ZX GBIC module provide an optical power budget of 21.5 dB. You should measure your cable plant with an optical loss test set to verify that the optical loss of the cable plant (including connectors and splices) is less than or equal to 21.5 dB. The optical loss measurement must be performed with a 1550-nm light source.

Function And knowledge With GBIC Transceiver Modules

Gigabit Interface Converter referred to as GBIC, Gigabit convert electrical signals to optical signals interface device. GBIC transceiver is probably the many types of transceivers that will send and receive data. GBIC is designed for hot-swappable. GBIC interchangeable products meet international standards. The GBIC interface design Gigabit switch interchangeable flexible to take into account a sizable market share available in the market.

GBIC transceiver

Functions

The GBIC transceiver functions being an input/output transceiver. It plugs into the gigabit Ethernet port on a single end, for instance a port found on network switching equipment. On the other end, the transceiver is attached to the fiber optic network, usually via fiber optic patch cords. The unit is seen as a features, including the wavelengths it can handle, how fast and efficiently it transmits data, the energy it needs to operate, and what distance it could transmit data over. These are the basic main considerations when purchasing a GBIC transceiver to make sure it meets network performance requirements.

Other important features of a GBIC transceiver which increase energy efficiency initiatives are how the unit offers low power dissipation and emits little electromagnetic interference. Each device can install and performance without disrupting anything, but this plug and play capability could be offset by the need to disconnect patch cords before it is installed or removed. Harmful electrical currents and data discrepancies can happen, and it is usually wise to take precautions to avert this whenever you can, specifically in high-density networks.

Transfer Speed

Data rates vary on GBIC module model specifications, but they have a the least 1 gigabit per second. Manufacturers, such as Cisco, make GBIC modules with varying transfer speeds.

Signal Conversion

The GBIC can be a module which is plugged into a device that generates electrical signals and in to a device that generates optical signals. The GBIC converts both signals backwards and forwards as needed by the devices. The GBIC even offers identification and system information which allows each device to learn the other’s capabilities.

Uses

A GBIC module allows an individual to reconfigure fiber links, configure tailor receiver costs, link networking distances and organize network topologies based on set requirements. Utilized on a fiber optic or perhaps an Ethernet system, GBIC modules can be upgraded, substituted or plugged in without switching off the pc. This flexibility eliminates the need to replace entire system networking boards.
