Understanding fiber-optic technology is not that easy
A quality vendor will be able to give you module options from various manufacturers. An experienced, knowledgeable vendor can help you make an educated selection. This is why learning a little bit about your choices before you find a merchant will be key. Most vendors will have a wide selection for you to choose from. Modules are usually grouped by transmission speeds and support rates. These items have names like GBIC and XFP modules. Know exactly what you must have, as they all handle different speeds and wavelengths.
GBIC takes Ethernet data and transfers them out to the fiber optic network. This transceiver attaches fiber optic patch cords to the network. The abbreviation GBIC stands for giga-bit interface converter. Like other optics, GBIC is classified based on its transmission rate, optical power, and distance.
Considered to be the next generation of GBIC are SFP modules and Cisco SFP modules. These transceivers are smaller and only about half the size of GBIC. Due to their smaller fiber interface, they are simple to keep up and change. SFP modules have transport speeds that range from 100mbps to 4+gbps.
You will use XFP optics for 8g fiber channel and for 10g network applications. They are a small form factor hot pluggable, which makes them simple to change and easy to keep up. You will utilize regular XFP with multimode fiber and the remaining modules with single mode fiber.
The world of telecommunication modules is still growing. For the average person, these constant changes just make things more difficult. Most merchants will be able to offer you more than just these few options. It is helpful to know that they understand a wide range of related items. By selling all types of related merchandise, they should have all the knowledge you need for help. A knowledgeable merchant will be able to answer all of your technical questions for you.
