Do all SFP interfaces on a switch need optical modules

SFP ports are modular network interfaces used to connect switches, routers, servers, and fiber optic links through interchangeable transceiver modules. Unlike standard RJ45 Ethernet ports, SFP ports can support both fiber optic and copper Ethernet connections depending on the installed module. Think of it as the “translator” for your network equipment, converting electrical signals into optical signals. Small Form-factor Pluggable (SFP) is a compact, hot-pluggable network interface module format used for both telecommunication and data communications applications. Transceiver compatibility is a key concern in enterprise network deployments. [pdf]
