SFP is a small pluggable module commonly used in network devices such as switches and routers. It can convert electrical signals into optical signals, or convert optical signals into electrical signals, thereby realizing the connection between network devices and optical fibers or copper cables.
Optical Network Units (ONU) and Optical Network Terminals (ONT) are essential devices in modern broadband infrastructures, particularly within Passive Optical Networks (PON). These units transform optical signals into electrical ones, allowing high-speed internet access in various settings, includin
