Optical fiber transceivers are most often implemented as user-swappable modules in SFP form or
on older devices.
Modern Fibre Channel devices support SFP transceiver, mainly with LC (Lucent Connector) fiber connector. Older 1GFC devices used
transceiver, mainly with SC (Subscriber Connector) fiber connector.
The SFP transceiver is not standardized by any official standards body, but rather is specified by a multi-source agreement (MSA) among competing manufacturers. The SFP was designed after the
interface, and allows greater "port density" (number of transceivers per cm along the edge of a mother board) than the
, which is why SFP is also known as mini-
. The related Small Form Factor transceiver is similar in size to the SFP, but is soldered to the host board as a through-hole device, rather than plugged into an edge-card socket.
An interesting and relatively recent development relating coarse WDM is the creation of
and small form factor pluggable (SFP) transceivers utilizing standardized CWDM wavelengths.
and SFP optics allow for something very close to a seamless upgrade in even legacy systems that support SFP interfaces. Thus, a legacy switch system can be easily "converted" to allow wavelength multiplexed transport over a fiber simply by judicious choice of transceiver wavelengths, combined with an inexpensive passive optical multiplexing device.
The SFP interfaces a network device motherboard (for a switch, router, media converter or similar device) to a fiber optic or copper networking cable. SFP transceivers are designed to support SONET, gigabit Ethernet, Fibre Channel, and other communications standards. Due to its smaller size, SFP obsolesces the formerly ubiquitous gigabit interface converter (
); the SFP is sometimes referred to as a Mini-
. In fact, no device with this name has ever been defined in the MSAs.
A gigabit interface converter (
) is a standard for transceivers, commonly used with Gigabit Ethernet and fibre channel in the 2000s. By offering a standard, hot swappable electrical interface, one gigabit port can support a wide range of physical media, from copper to long-wave single-mode optical fiber, at lengths of hundreds of kilometers.
standard is non-proprietary and is defined by the Small Form Factor committee in document number 8053i. The first publication of the proposal was in November 1995. A few corrections and additions were made through September 2000. Robert Snively of Brocade Communications was technical editor. Original contributors were AMP Incorporated, Compaq Computers, Sun Microsystems, and Vixel Corporation.
The German Banking Industry Committee (
) ( / DK) is an industry association of the German banking industry. Its decisions are held normative for the national banking sector – either directly by interbank treaties or indirectly by preparing a corresponding ministerial or Bundesbank decision.
Transceivers are called Medium Attachment Units (MAUs) in IEEE 802.3 documents and were widely used in 10BASE2 and 10BASE5 Ethernet networks. Fiber-optic gigabit, 10 Gigabit Ethernet, 40 Gigabit Ethernet, and 100 Gigabit Ethernet utilize transceivers known as
, SFP, SFP+, QSFP, XFP, XAUI, CXP, and CFP.
The appeal of the
standard (and in general) in networking equipment, as opposed to fixed physical interface configurations, is its flexibility. Where multiple different optical technologies are in use, an administrator can purchase GBICs as needed, not in advance, and they can be the specific type needed for each link. This lowers the cost of the base system and gives the administrator far more flexibility. On the other hand, if a switch will mostly have one port type (especially if that port type is copper) purchasing a switch with that port type built in will be cheaper and take up less space per port.
The company's first product was the Summit1 Gigabit Ethernet switch, a 6 Port Ethernet Layer 3 switching device featuring dual gigabit interface converter (
) 1000BASE-SX interfaces. This product shipped in 1997 and won the "Best of Show" award at Networld+Interop. The Summit1 was also named the "Best of the Best Grand Winner" for the event. Extreme Networks won Best of Show awards at Networld+Interop five consecutive years, 1997 through 2001 with its Summit PX1 application switch, a Layer 4-7 device.
The following standard, Fast Ethernet introduces division onto Media Access Controller (MAC) and Physical Layer Interface (PHY) layers connected with Media Independent Interface (MII). Some early Fast Ethernet hardware had a physical external MII connectors, functionally similar to AUI connector. However, the tradition of using a separate low-level I/O device in networking has continued in fast optical fiber network interfaces, where the
, XENPAK, XFP, and enhanced small form-factor pluggable (SFP+) pluggable transceiver modules using the XAUI interface play a similar role.
