Finally, there is a 10GBASE-LX4 media type, which uses wave division multiplexing technology to send signals over four wavelengths of light carried over a single pair of fiber optic cables. The design goal for this media system is from 2 meters up to meters over multimode fiber or from 2 meters up to 10 kilometers over single-mode fiber, with longer distances possible depending on cable type and quality. This site provides information on 10 Gigabit Ethernet and presentations on the evolving 10 Gigabit Ethernet standard.
Optical Fiber and 10 Gigabit Ethernet. An excellent whitepaper on optical fiber technologies and issues with 10 Gigabit Ethernet, provided by the 10 Gigabit Ethernet Alliance. The sizes of these five modules are getting smaller and smaller.
There are two types of 10 GbE network, which differ by the type of cable used to connect devices. Skip to content. Posted on October 13, by Admin. Bookmark the permalink. Share this page Share. It utilizes multiple beams, which bounce diagonally throughout a somewhat larger The beams are then collected at the receiving end and recombined.
This allows multi-mode to achieve high speeds at a lower power use -and usually slightly lower cost- but the nature of the format means that interference and signal degrading become an issue in longer cables. So multi-mode is generally used for Short Reach SR applications. This one is actually pretty easy. SR transceivers are almost always multi-mode, and optimized for high speeds over relatively short distances.
However, the much higher-powered OM3 and OM4 formats can push that into the hundreds of meters for a single cable. LR transceivers are designed for long-range communications, such as wiring buildings together on a large campus or even setting up a Metro Area Network MAN. Higher end cables and transceivers can support transmissions of several kilometers. Basically, these are just extremely long-range fiber variations.
