What Is a Gigabit Interface Converter?

Gigabit Ethernet interface converter , ie high-speed Ethernet interface converter (English: Gigabit Interface Converter , referred to as GBIC ), is a signal converter commonly used in high-speed Ethernet and Fibre Channel. Through this conversion The standard specifications of the device, the ports of high-speed Ethernet devices can directly correspond to various physical transmission interfaces, including copper wires, multimode fiber and single-mode fiber.

High-speed Ethernet interface converter (English: Gigabit Interface Converter , referred to as GBIC ) is a high-speed Ethernet circuit and

Fibre Channel ( FC ) is a high-speed network interconnection technology (usually operates at 2Gbps, 4Gbps, 8Gbps, and 16Gbps), and is mainly used for connection

A small form-factor pluggable transceiver (SFP) is a small, hot-swappable optical transceiver for optical communications applications in telecommunications and data communications. The SFP connects the motherboard of the network equipment such as switches, routers, etc. to the optical fiber or UTP cable. SFP is an industrial specification supported by some fiber optic component providers.

SFP transceivers support SONET, Gigabit Ethernet, Fibre Channel, and some other communication standards. This standard is extended to SFP + and can support 10.0 Gbit / s transmission rates, including 8 gigabit Fibre Channel and 10GbE. The fiber optic and copper versions of the SFP + module are introduced. Compared with the Xenpak, X2, or XFP versions of the module, the SFP + module leaves part of the circuit implemented on the motherboard instead of the module.

SFP Gigabit Ethernet interface converter SFP type

There are many different types of SFP transceivers for transmission and reception. Users can select the appropriate transceiver for each link to provide "optical performance" based on the type of fiber available (such as multimode fiber or single-mode fiber). SFP optical modules can be generally divided into the following categories:

• SX: 850 nm wavelength, transmission distance 550 meters, using multimode fiber MMF

• LX: 1310 nm wavelength, 10 km transmission distance, using single-mode fiber SMF

• EX: 1310 nm wavelength, transmission distance of 40 km, using single-mode fiber SMF

• ZX: 1550 nm wavelength, transmission distance of 80 kilometers, using single-mode fiber SMF

• TX: electrical port module, using RJ-45 copper cable interface

• CWDM: Sparse WDM SFP Optical Module

• DWDM: Dense Wavelength Division Multiplexing SFP Optical Module

Commercial SFP transceivers can provide rates up to 4.25 G bps. Several packages of 10 Gbps transceivers are XFP, and a new variant "SFP +" that is basically consistent with the SFP package. ^[2]
