How are optical modules connected to the switch
Optical Interface: The optical transceiver connects to the network through an optical interface, typically through a small form-factor pluggable (SFP) module or similar interface. In the era of 5G, AI, and high-speed data centers, optical modules serve as the core bridge for converting electrical signals to optical signals (and vice versa), enabling fast, reliable data transmission across networks. Among various optical module form factors, SFP (Small Form-Factor Pluggable). SFP (Small Form-factor Pluggable) is a compact, hot-pluggable network interface module used to connect network devices (switches, routers, firewalls) to fiber optic or copper cables. This lets you send data far away. Among many optical modules, the SFP + optical module is one of the most widely used optical modules. Different connection modes can meet different network.
