What are SFP Transceivers?
SFP is a small-scale form-factor pluggable transceiver that provides connectivity between a networking device and a cable. These compact, hot-swappable transceivers are widely used in data communication and networking.
An important feature of SFP over other transceivers is its ability to support different communication standards such as Gigabit Ethernet, SONET, and Fiber Channel. In addition to this, SFP optical transceiver can be easily adjusted to connect with both optical fiber and copper cable.
SFP’s are also known as miniGBIC. In miniGBIC, GBIC stands for Gigabit Interface Converter and as SFP is smaller in size, it is called mini GBIC. The difference between SFP and GBIC is the size and the connectors used in them. While LC connectors are used in the former, SC connectors are used in the later.
Single-mode and multi-mode SFP
SFP’s can work with both single-mode and multimode fiber. SFP transceivers that work with single-mode fiber are called single-mode SFP while SFP transceivers that work with only multi-mode fiber are called Multimode fiber. The single-mode optical fibers have a narrow wavelength and smaller core which means single-mode SFP can carry the signal to large distances. Multi-mode SFP, on the other hand, carries the data to shorter distances.
In today’s world where enterprises want high speeds. 10GSFP transceiver module which is also called SFP+ provides 10G speeds. The SFP+ modules are similar to SFP and their connectors and cables are also the same.
CWDM and DWDM
CWDM transceivers use CWDM technology. CWDM comes with a variety of receiver and transmitter types and provides a cost-effective solution to adopt Gigabit Ethernet and fiber channel. DWDM (Dense Wavelength-Division Multiplexing) transceivers, on the other hand, provide high performance and high bandwidth and accept multi-rate interfaces and protocols.
