1U Rack PLC Splitters refers to a 1U (1U height unit) rack-mounted grating integrated device used for signal distribution and beam splitting in fiber optic communication systems.PLC (Planar Lightwave Circuit) Splitters are optical splitters based on the manufacture of silicon optical chips, which can split a single optical signal into multiple optical signals, or Combine multiple optical signals into one optical signal.

The 1U Rack PLC Splitters are designed to integrate multiple PLC Splitters into a 1U high rack unit for easy installation and management in a rack mounted fiber optic communication system. This design allows system administrators to more easily deploy and manage large numbers of fiber optic splitters while saving rack space.
