A single-mode fiber transceiver is a type of optical transceiver module, which is a self-contained component that can receive and transmit data using single-mode optical fiber cables. Modern transceivers are called small form-factor pluggable (SFP) transceivers as they are designed to fit into a variety of enterprise-grade network equipment such as switches and routers.
Techopedia Explains Single-Mode Fiber Transceiver
A single-mode fiber transceiver connects single-mode fibers with different qualities such as dispersion-shifted fiber and nonzero dispersion-shifted fiber, as well as regular optical fiber cables. By 2005, commercially available single-mode fiber transceivers allowed speeds of up to 10 gigabits per second at distances of more than 80 km.
Most modern fiber transceivers can work with both single-mode and multi-mode fibers. However, dedicated single-mode fiber transceivers are still available, which are cheaper since they are made with fewer components and functions in mind. The quality or performance of transceivers varies depending on the length of the cable, speed required or the technology and protocols being supported.
