PLC Fiber Optic Splitter can be categorized by the PLC splitter chip they use, meaning there are 1xN and 2xN PLC splitters, such as 1x4 splitter, 1x8 splitter, 1x16 splitter, 2x32 splitter, 2x64 PLC splitters, etc. Users can choose different input and output numbers depending on subscriber conditions or cable length.

CWDM (Coarse Wavelength Division Multiplexing) is an optical fiber communication device that uses wavelength separation technology to combine multiple optical signals of different wavelengths into one fiber for transmission.It can merge multiple input ports into one output port to improve fiber utilization and transmission distance.

Optical Switch (OS) is mainly used to realize physical switching or other logical operations of Optical signals in optical paths, and is often used as a key component of optical path switching in optical Cross-connect technology.
