The difference of SFP optical module and GBIC optical module

The difference of SFP optical module and GBIC optical module

 

1.What is GBIC?

 

GBIC means Gigabit Interface Converter which is the interface device converts the gigabit electrical signals to optical signals. In design, GBIC can be used for hot-plug. GBIC is the interchangeable product that meets the international standards.

 

GBIC Transceiver

 

For the feature of interchangeable flexible, the Gigabit switch design with the interface of GBIC has a large share in the market.

 

2.What is SFP optical module?

 

SFP is the abbreviation of SMALL FORM PLUGGABLE. It can be understood as the upgraded version of GBIC simply. The volume of SFP optical module is half of GBIC optical module.

 

SFP Module

 

Therefore, we can configure more than double the number of ports on the same penal. The other function of SFP fiber optical module is in accord with GBIC optical module basically. So, some switch manufacturers said that the SFP module is the mini GBIC module.

 

In short, the volume of SFP optical module is half of GBIC optical module and can be configured more than double the number of module interfaces. And the interface of SFP is LC, GBIC is SC interface generally.

CFP Module

CFP is a hot-pluggable transceiver that supports a wide range of 40 and 100 Gb/s applications such as 40G and 100G Ethernet, OC-768/STM-256, OTU3, and OTU4. Different versions of CFP modules can support various link distances over either multimode or single mode fiber optics. The CFP module includes numerous innovative features like advanced thermal management, EMI management and enhanced signal integrity design, as well as an MDIO-based management interface.

How to remove a SFP Transceiver Module?

Complete these steps in order to remove the SFP transceiver:1. Attach an ESD-preventive wrist strap to your wrist and to the ESD ground connector or a bare metal surface on your chassis.2. Disconnect the network fiber-optic cable or network copper cable from the SFP Transceiver Module connector.For optical SFP transceivers, immediately reinstall the dust plugs in the SFP transceiver optical bores and the fiber-optic cable LC connectors.Tip: For reattachment of fiber-optic cables, note which connector plug is send (TX) and which is receive (RX).3. Release and remove the SFP Transceiver Module from the socket connector.   If the SFP transceiver has a Mylar tab latch, pull the tab gently in

Working Principle of a fiber optic transceiver module

In fiber optic data links, the transmitter converts an electrical signal into an optical signal, which is coupled with a connector and transmitted through a Fiber Optic Cable.  The light from the end of the cable is coupled to a receiver, where a detector converts the light back into an electrical signal. Either a light emitting diode (LED) or a laser diode is used as the light source. As the core of the optical communication devices, Optical transceiver module completes optical signal light - electricity / electricity - light conversion function. Internally can be divided into two separate parts: receive and transmit. The receiving part of the light - electricity conversion to send part
