For optical modules, the SFP contains a TOSA (Transmit Optical Subassembly) and ROSA (Receive Optical Subassembly) to handle the fiber signal. For copper SFP modules (RJ-45), the module integrates the necessary PHY and magnetics to convert electrical signals to. Small Form-factor Pluggable (SFP) is a compact, hot-pluggable network interface module format used for both telecommunication and data communications applications. Think of it as the “translator” for your network equipment, converting electrical signals into optical signals. Optical transceivers are compact, hot-pluggable devices that convert electrical signals into optical signals, enabling high-speed data transmission across switches, routers, and other networking equipment. Transceiver compatibility is a key concern in enterprise network deployments.
