Fiber optic transceivers are electro-optical devices that convert electrical signals used by network equipment (switches, routers, servers) into optical signals for transmission over fiber optic cables, and vice-versa. They perform key functions:Optical fiber transceiver is a very cost-effective and flexible device. It is generally used in real network environments where Ethernet copper cables cannot be covered and fiber optics must be used to extend. A fiber optic transceiver (also called an optical transceiver) is a compact module that both transmits and receives data signals through optical fibers. It is the unit that actually sends and receives light on a fiber link. Typical form factors include SFP, SFP+, QSFP, CFP, etc.
