Mini GBIC vs SFP: Is It the Same?
We’ve got very familiar with GBIC transceiver: short for gigabit interface converter, it is developed in 2000 as a hot swappable transceiver that commonly used in Gigabit Ethernet and Fiber Channel. But as the demand for higher bandwidth and transmission speed keeps accelerating, more ports are needed to be fit in a line card. So Mini GBIC module is developed to provide more interface in the same line card. Mini GBIC is a smaller version that only half the size of GBIC transceiver. So what exactly is Mini GBIC module? Mini GBIC vs SFP: Is it the same? This article will handle all the confusions for you.
What Is Mini GBIC Transceiver?
Mini GBIC, also called SFP transceiver (SFP means small form factor) was announced in 2001. It has the same functionality with former GBIC module but built with a smaller form factor. Mini GBIC and SFP transceiver actually refer to the same thing, and they are interchangable. Mini GBIC transceiver is a compact, hot-pluggable module that can be installed and removed while the switch is powered on. Mini GBIC provides flexibility for using fiber Gigabit connections in both data and telecommunication applications. So the shipment of Mini GBIC had soon outgrown GBIC transceiver and secured its position in Gigabit SFP based network.
What Is a Mini GBIC Used For?
Mini GBIC transceivers allow technicians to easily configure and upgrade electro-optical communications networks. It is a plug-in module that can be removed and replaced without turning off the system. Mini GBIC transceiver is typically employed in fiber optic and Ethernet systems for high-speed networking. The data transfer rate is one gigabit per second (1 Gbps) or more. Mini GBIC is designed for high performance integrated duplex data transmission over optical fiber. It can support SONET, Gigabit Ethernet, Fiber Channel, and other communications standards.
Mini GBIC Transceiver Classification
Mini GBIC can be classified into different groups according to data rate, operating wavelength, transmission distance and so on.
Divided by rate:155M/622M/1.25G/2.125G/4.25G/8G/10G,155M and 1.25G market is more used.
Divided by wave length : 850nm/1310nm/1550nm/1490nm/1530nm/1610nm.
The 850nm wavelength is SFP multimode, and the transmission distance is up to 550 m.
1310/1550 nm is SFP single-mode, and the transmission distance ranges from 2 km to 80 km.
The bare Mini GBIC module basically has no difference if they have no mark. So manufacturers make different colors of pull ring to distinguish them.
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.
Divided by distance: Mini GBIC transceiver can also be classified by different transmission distance, see the following table:
Mini GBIC transceiver has the advantages of small and low-cost to meet the needs of high-density transmission. So it has replaced GBIC transceiver to become mainstream in the data center.
