There are a number of small pluggable optical
You will locate many different optical modules that act at different speeds and ranges. There are XENPAK modules, XFP modules, X2 modules, GBIC modules, SFP modules, SFP+ modules, and SFP-BIDI pluggables. Listed below is detailed data on just a few.
Modules like GBIC have special working functions such as attaching the Ethernet network and the fiber optic network. GBIC stands for gigabit interface converter, and is an optic used with one plug in an Ethernet port and the other plug to connect fiber patch cords. GBIC's are hot pluggable, which offers you the ability to mix one type of interface with another and not have to shut down. Optical power and wavelengths, working distance, and transmission velocity determine the groups that GBIC modules are put in.
New generation GBIC modules are thought to be the SFP transceivers. Short for small form-factor pluggable, SFP modules are also hot pluggable optics. Hot pluggable transceivers are much easier to keep up and switch out in comparison to basic interface modules. Items like Cisco SFP transceivers tend to be smaller and are only about half the size of GBIC optics. These modules send rates that range from 100Mbps to about 4+Gbps. You will see that these modules transmit up to 120+kilometers down to about 500 meters.
Optics such as XENPAK are known to be the largest of the transceiver modules. There is a huge range of XENPAK modules that function with different lines including copper line, multimode optical fiber line and single mode optical fiber line. Multimode fibers function at a distance of up to 300 meters while typical copper lines operate up to about 15 meters. Most single mode modules span up to 80km at maximum. Produced first under the Multi-Source Agreement were these 10Gbps pluggable optical transceivers.
Whatever type of transceiver optics you are in the market for, you know that you are consistently getting products that are made under the highest standards possible. Depending on your fiber optic networking experience, you may be in the market for other technical items like patch cords and media converters which are also easily purchased. With today's technology, you can count on optical modules and all other networking merchandise to continue to see advancements, becoming faster and better.
