Ethernet over fiber is a networking technology that delivers Ethernet bandwidth ranging up to 400 Gbit/s using optical fiber lines. Such wired transmission methods extend connectivity over long distances up to 200 km, support higher bitrates and provide far greater immunity from electromagnetic interference (EMI) than electrical connections.
A standardized variant of 10 Gigabit Ethernet, called WAN PHY, is designed to inter-operate with OC-192 transport equipment while the common version of 10 Gigabit Ethernet is called LAN PHY (which is not compatible with OC-192 transport equipment in its native form). The naming is somewhat misleading, because both variants can be used on a wide ...
It offers the advantages of low power, low cost and low latency, but has a bigger form factor and more bulky cables than the newer single-lane SFP+ standard, and a much shorter reach than fiber or 10GBASE-T. This cable is fairly rigid and considerably more costly than Category 5/6 UTP or fiber.
The wire speed should not be confused with the line bitrate, also known as gross bit rate, raw bitrate or data signalling rate, which is 125 Mbit/s in fast Ethernet. In case there is a physical layer overhead, for example due to line coding or error-correcting codes , the line bitrate is higher than the wire speed.
Fiber-optical cable FOIRL: 802.3d-1987 (9.9) ST: 1000 m FDDI-style MMF: Fiber-optic inter-repeater link; the original standard for Ethernet over fiber, superseded by 10BASE-FL, deprecated 2011 10BASE-F: 802.3j-1993 (15) A generic term for the family of 10 Mbit/s Ethernet standards using fiber optic cable: 10BASE-FL, 10BASE-FB and 10BASE-FP.
FTTP configurations that bring fiber directly into the building can offer the highest speeds since the remaining segments can use standard Ethernet or coaxial cable. Fiber is often said to be "future-proof" because the data rate of the connection is usually limited by the terminal equipment rather than the fiber, permitting substantial speed ...
