A 10GBASE-SR SFP+ transceiver. 10GBASE-SR ("short range") is a port type for multi-mode fiber and uses 850 nm lasers. [28] Its Physical Coding Sublayer (PCS) is 64b/66b and is defined in IEEE 802.3 Clause 49 and its Physical Medium Dependent (PMD) sublayer in Clause 52. It delivers serialized data at a line rate of 10.3125 Gbd. [29]
Small Form-factor Pluggable (SFP) is a compact, hot-pluggable network interface module format used for both telecommunication and data communications applications. An SFP interface on networking hardware is a modular slot for a media-specific transceiver , such as for a fiber-optic cable or a copper cable. [ 1 ]
XFP modules are commonly available in several different categories: [citation needed] SR - 850 nm, for a maximum of 300 m; LR - 1310 nm, for distances up to 10 km; ER - 1550 nm, for distances up to 40 km; ZR - 1550 nm, for distances up to 80 km; The XFP packaging was smaller than the XENPAK form-factor which had been published earlier (by ...
10GBASE-ZR: Multi-vendor SC, LC Offered by various vendors; supports 80 km or more over single-mode fiber using 1,550 nm wavelength 10GBASE-SW: 802.3ae-2002 (52) A variation of 10GBASE-SR with 9.58464 Gbit/s, designed to be mapped directly as OC-192/STM-64 SONET/SDH streams (850 nm wavelength) 10GBASE-LW: 802.3ae-2002 (52)
Optical fiber transceivers are most often implemented as user-swappable modules in SFP form or GBIC on older devices. IEEE 802.3ab, which defines the widely used 1000BASE-T interface type, uses a different encoding scheme in order to keep the symbol rate as low as possible, allowing transmission over twisted pair.
The Cisco Nexus series switches are modular and fixed port network switches designed for the data center. Cisco Systems introduced the Nexus Series of switches on January 28, 2008. The first chassis in the Nexus 7000 family is a 10-slot chassis with two supervisor engine slots and eight I/O module slots at the front, as well as five crossbar ...
