What Is Optical SFP?

An Optical SFP (Small Form-factor Pluggable) is a compact, hot-swappable transceiver module used in networking devices to transmit and receive data over optical fiber. It converts electrical signals from networking equipment into optical signals for transmission through fiber cables, and vice versa. Due to its standardized design, it can be easily inserted into compatible ports on switches, routers, media converters, and OLTs.
