Purchasing optical transceiver modules should
Optical transceiver modules transport waves of information through optical fibers finer than human hair. Modules transport and receive optical signals. Each of these form factors are developed under the Multi-Source Agreement. Particular standards must be met in their building. Optical transceivers are typically grouped by transport speeds. Each supports rates from 1Gbps to 10Gbps. 1Gbps form factors are typically known as SFP's and GBIC modules. Some support rates of 100mbps and others greater than 4Gbps. Modules known as XENPAK, XFP, X2 and SFP+ support velocities of up to 10Gbps transmission.
SFP modules means small form factor pluggable. The form factors are considered to be the newer version of GBIC. GBIC is a half size broader, while SFPs use a smaller fiber interface. Distances of transmission start at 500 meters and go up to 120+ kilometers. They are easy to change and easy to fix.
XENPAK modules are the widest in 10G transceiver interfaces and include a dual SC fiber interface. Cisco SFP modules are available in multi-mode and single-mode optical fiber wire, as well as operating in copper cable. 15 meters is the normal transmission span of a copper module. 300 meters is the transmission reach of multimode optics.
XFP transceivers are developed for 10G network applications, including 10G Ethernet. Some of the leading manufacturers in the industry set the standards for their development. Considered to also be a hot pluggable, they are easy to change out and keep. Laser optimized multimode fibers are used with the regular XFP module.
GBIC is an abbreviation for giga-bit interface converter. It mainly works to transform signals from the Ethernet network to the fiber optic network. This module connects networks to the fiber optic patch cords. Distance, power, transfer rate, and wavelengths is what classifies this module. They are hot pluggable, which permits one port to be changed to another, without having to power down the switch or router.
The business of optical transceivers is always expanding and growing. The list above is only a few of the module options that you will have to select from. Understanding your options in transceiver modules is just as important as finding the right retailer. It will be helpful to find a vendor who sells all models of optical networking products. It's valuable that they at least have a background and experience in all kinds of fiber optical products. If this is a new field to you, an experienced distributor will be extremely valuable.
