1000BASE-SX GBIC. 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 kilometers.
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 ]
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 CFP transceiver is specified by a multi-source agreement (MSA) among competing manufacturers. [2] The CFP was designed after the small form-factor pluggable transceiver (SFP) interface, but is significantly larger to support 100 Gbit/s.
QSFP28 modules use the CAUI-4 electrical interface. SFP-DD or Small Form-factor Pluggable – Double Density modules use the 100GAUI-2 electrical interface. Cisco's CPAK optical module uses the four lane CEI-28G-VSR electrical interface. [127] [128] There are also CXP and HD module standards. [129] CXP modules use the CAUI-10 electrical interface.
The Cisco Catalyst 9600 Series is a modular chassis-based core switch family. This series can support interfaces up to 100 Gigabit Ethernet in speed and redundant supervisor modules, power supplies and fans. [17] The Cisco Catalyst 9400 Series is a chassis-based access and distribution switch
