Difference between GBIC & SFP(mini gbic)

Tweet

 A gigabit interface converter (GBIC) is a standard for transceivers, commonly used with Gigabit Ethernet and fibre channel in the 1990s. 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.The small form-factor pluggable (SFP Fiber Optic Transceiver) is a version of Mini-GBIC. It supports data rates up to 10 Gbit/s. The SFP Fiber

Optic Transceiver are available with a variety of transmitter and receiver types.The small form-factor pluggable (SFP) or Mini-GBIC is a compact, hot-pluggable transceiver used for both telecommunication and data communications applications. It interfaces a network device mother board (for a switch, router, media converter or similar device) to a fiber optic or copper networking cable. It is a popular industry format jointly developed and supported by many network component vendors.SFP transceivers are designed to support SONET, Gigabit Ethernet, Fibre Channel, and other communications standards. Due to its smaller size, SFP obsoleted formerly used Gigabit interface converter.

SFP transceivers are available with a variety of transmitter and receiver types,

 

 for multi-mode fiber, with black or beige extraction lever

• SX - 850 nm, for a maximum of 550 m at 1.25 Gb/s (Gigabit Ethernet) or 150m at 4.25 Gb/s (Fibre Channel)

    for single-mode fiber, with blue extraction lever

• LX - 1310 nm, for distances up to 10 km
• BX - 1490 nm/1310 nm, Single Fiber Bi-Directional Gigabit SFP Transceivers, paired as BS-U and BS-D for Uplink and Downlink respectively, also for distances up to 10 km  
• 1550 nm 40 km (XD), 80 km (ZX), 120 km (EX or EZX)
•  CWDM and DWDM transceivers at various wavelengths achieving various maximum distances

    for copper twisted pair cabling

• 1000base-T - these modules incorporate significant interface circuitry and can only be used for Gigabit Ethernet, as that is the interface they implement. They are not compatible with (or rather: do not have equivalents for) Fibre channel or SONET.

    The 850nm wavelength is SFP multimode , and the transmission distance is 2KM below .

    1310/1550nm is SFP single-mode , and the transmission distance is longer than 2KM.

    850nm/1310nm/1550nm price relatively cheaper than the other three.

The bare module is easy to confuse if they have no mark,the manufacturers will make the color of pull ring to distinguish generally, For example:

Black pull ring is multi-mode, the wavelength is 850nm;

Blue is the 1310nm module;

Yellow is the 1550nm module ;

Purple is the 1490nm module and so on.

main difference between GBIC & SFP(min gbic)

1.GBIC is larger than SFP.

2.SFP is in prominent use while GBIC is already obsolete.

3.GBIC and SFP are equal in performance.
