If you are looking for optical modules or networking products, your options are unlimited in this advancing market. Most optic modules usually work to both emit and receive electronic optical signals. All optical transceiver modules must be made and created along the lines of the Multi-Source Agreement. Field professionals ensure that modules are made under this strict Agreement. All optical transceivers are put into module categories by their speed rates of transmission. Groups of modules support different rates that start at 1Gbps and go up to 10Gbps. Each support rate will help decide which networking merchandise will work best for you.
You will find many different optical modules that work at different speeds and ranges. There are XENPAK transceivers, XFP modules, X2 modules, GBIC modules, SFP modules, SFP+ modules, and SFP-BIDI transceivers. Listed below is detailed information on just a few.
Modules like GBIC transform electrical impulses from the Ethernet network to the fiber optic network. With one end connected to the Ethernet port and the other to the fiber patch cords, GBIC transceivers are useful devices, and are known as gigabit interface converters. Because GBIC optics are hot pluggable, you will never have to shut down when changing one style of interface with another. Optical power and wavelengths, working distance, and transmission speeds determine the groups that GBIC modules are put in.
SFP transceivers are considered to be the new type of GBIC modules. Short for small form-factor pluggable, SFP modules are also hot pluggable modules. Standard interface modules are much harder to swap out in comparison to the hot pluggable SFP styles. Items like Cisco SFP transceivers tend to be smaller and are only about half the size of GBIC modules. These modules send speeds that range from 100Mbps to about 4+Gbps. Ranges for transceivers are starting at about 500 meters and can go up to about 120+ kilometers.
XENPAK modules are the widest in transceiver modules. You will find different types of lines that operate with XENPAK, including multimode and single mode fiber lines, as well as copper lines. Multimode fibers work at a distance of up to 300 meters while typical copper lines work up to about 15 meters. Most single mode optics span up to 80km at maximum. These were some of the first 10Gbps optical transceivers produced under the Multi-Source Agreement.
No matter what style of transceiver modules you are looking for, you can be certain you are getting them produced under the highest standards. Accessories like media converters and patch cords are also available on the market, depending on what your needs are. Optical transceivers and all other networking items will always advance, becoming faster and easier to use.
