What Is the Maximum Distance For 10gbase-Er And 10gbase-Ew on A Segment of Single-Mode Fiber?

Answer:

The maximum distance for 10gbase-ER and 10gbase-EW on a segment of single-mode fiber is 40 kilometers. ER in 10GBase stands for extended reach. This standard defines a star topology and the length of segments is up to 40 kilometers and in meters, the maximum distance is 40,000 meters per segment length.

10 Gigabit Ethernet:

10gbase-ER is a computer networking group for transferring Ethernet frames at an estimate of 10 gigabits per second. Previously it only defines the full-duplex end-to-end link connected by network switches. CSMA/CD shared medium operation is not carried out in the previous generation. Repeater’s hubs and half-duplex operations have not existed in 10GbE.

The standard of 10-gigabit Ethernet bound a different physical layer’s standards (PHY). Networking devices like switches have different PHY varieties by pluggable PHY modules. Previous Ethernet cables used copper or fiber cable the maximum distance by copper wire is 100 meters. Higher cables are required because of their bandwidth requirements.

10gbase-ER is a type of optical fiber. Two basic types of optical fibers are single-mode in which light moves in a single path it is used for long paths, while in multimode it takes multiple routes used for less distance around 300 m.

Active optical devices that have optical electronics connected already remove the connecters between the optical module and the cable. These cables are cheap than other cables because the makers organize the electronics according to the length of a kind of cables.

10gbase-ER and 10gbase-EW:

10gbase- ER is single mode fiber. It uses 1550 nm lasers. At the rate of 10.3125 GBd transfer serialized data in a line. Its transmitter is an appliance with an externally modulated laser (EML). In 10gbase-ER over-engineered links has reached 10 km while in standard has 30 km.
