Gigabit interface converter (GBIC) is a standard for transceivers. First defined in 1995, it was used with Gigabit Ethernet and Fibre Channel . By standardizing on a hot swappable electrical interface, a single gigabit port can support a wide range of physical media, from copper to long-wave single-mode optical fiber , at lengths of hundreds of ...
The XFP (10 gigabit small form-factor pluggable) is a standard for transceivers for high-speed computer network and telecommunication links that use optical fiber. It was defined by an industry group in 2002, along with its interface to other electrical components, which is called XFI .
A fiber media converter is a simple networking device that makes it possible to connect two dissimilar media types such as twisted pair with fiber optic cabling. They were introduced to the industry in the 1990s, and are important in interconnecting fiber optic cabling-based systems with existing copper-based structured cabling systems.
Unlike most non-SFP, copper 1000BASE-T ports integrated into most routers and switches, 1000BASE-T SFPs usually cannot operate at 100BASE-TX speeds. 100 Mbit/s copper and optical – some vendors have shipped 100 Mbit/s limited SFPs for fiber-to-the-home applications and drop-in replacement of legacy 100BASE-FX circuits.
Generally, twinax cables shorter than 7 meters are passive and those longer than 7 meters are active, but this may vary from vendor to vendor. SFP+ Direct Attach Copper (DAC) is a popular choice for 10G Ethernet reaches up to 10 m [8] due to low latency and low cost. One major application is connecting network hardware through their SFP+ ...
Optical fiber manufacturers have greatly refined their manufacturing process since that standard was issued and cables can be made that support 10 GbE up to 400 meters. Laser optimized multi-mode fiber (LOMMF) is designed for use with 850 nm VCSELs. Older FDDI grade, OM1, and OM2 fiber can be used for 10 Gigabit Ethernet through 10GBASE-LRM.
10 Gigabit Ethernet NICs are also available, and, as of November 2014, are beginning to be available on computer motherboards. [6] [7] A Qlogic QLE3442-CU SFP+ dual-port NIC. Modular designs like SFP and SFP+ are highly popular, especially for fiber-optic communication. These define a standard receptacle for media-dependent transceivers, so ...
Fibre Channel typically runs on optical fiber cables within and between data centers, but can also run on copper cabling. [3] [4] Supported data rates include 1, 2, 4, 8, 16, 32, 64, and 128 gigabit per second resulting from improvements in successive technology generations. The industry now notates this as Gigabit Fibre Channel (GFC).
