to connect the main distribution frame and the terminal equipment and to branch the optical signal.
FBT splitters are widely accepted and used in passive networks, especially for instances where the split configuration is smaller (1×2, 1×4, 2×2, etc.).
Waveguides are fabricated using lithography onto a silica glass substrate, which allows for routing specific percentages of light.
As a result, PLC splitters offer accurate and even splits with minimal loss in an efficient package.
The PLC splitter is a micro-optical element using photolithographic techniques to form optical waveguide at medium or semiconductor substrate for realizing branch distribution function.
