What is the difference between a GBIC and an SFP?

GBIC and SFP are both a kind of hot-pluggable optical transceiver which is mainly used to convert between the optical signal and electrical signal. However, GBIC and SFP are equal in performance. The only major difference between them is their size. SFP module is much smaller than GBIC module.

What is GBIC and SFP for?

They are used to convert optical and electrical signals. GBIC stands for Gigabit Interface Converter and SFP stands for Small Form-factor Pluggable. Although relative models of each technology are equal in performance, SFP’s are generally considered as an upgraded version of a GBIC module, because they are smaller.

What is SFP 1000BASE-SX?

1000BASE-SX is a physical layer specification for Gigabit Ethernet over fiber optic cabling as defined in IEEE 802.3z. So 1000BASE-SX SFP supports link length of up to 550m (depending on fiber type) on multimode fiber at 1Gbps. This optic works at 850nm wavelength and uses a LC connector.

What is a GBIC module?

(GigaBit Interface Converter) A small transceiver that plugs into the GBIC port of a network switch and connects to Fibre Channel and Gigabit Ethernet (GbE) optical fiber cables at the other end. GBIC modules are hot swappable and contain ID and system information for the switch.

What is the purpose of a GBIC?

A gigabit interface converter (GBIC) is a transceiver that converts electric currents (digital highs and lows) to optical signals, and optical signals to digital electric currents. The GBIC is typically employed in fiber optic and Ethernet systems as an interface for high-speed networking.

Is SFP Compatible with SFP+?

SFP and SFP+ modules look exactly the same. And as they have the same size, your SFP transceiver will fit seamlessly into an SFP+ switch port and vice versa. If you plug an SFP device into an SFP+ port, the speed will be locked at 1 Gbps.

What is a copper GBIC?

The industry-standard Cisco Gigabit Interface Converter (GBIC) is a hot-swappable input/output device that plugs into a Gigabit Ethernet port or slot, linking the port with the network.

Is 1000BASE LX single mode or multimode?

The 1000BASE-LX/LH SFP, compatible with the IEEE 802.3z 1000BASE-LX standard, operates on standard single- mode fiber-optic link spans of up to 10 km and up to 550 m on any multimode fibers.

What is SFP mini GBIC?

These SFP transceivers (Small Form fractor Pluggables), also called Mini-GBICs, are to connect a fiber optic network cable to a data communications unit like a switch, router, firewall, or media converter which contains a SFP slot to accept the SFP device.

Is GBIC still used?

A gigabit interface converter (GBIC) is a standard for transceivers, first defined in 1995 and commonly used with Gigabit Ethernet and fibre channel for some time. Announced in 2001, it largely made the GBIC obsolete.
