1x3 Branch type PLC Splitter high return loss for FTTH system
Fiber Optic PLC Splitter Description
According to the principle, fiber optic splitters can be divided
into Fused Biconical Taper (FBT) splitter and Planar Lightwave
Circuit (PLC) splitters.
The FBT splitter is one of the most common. FBT splitters are
widely accepted and used in passive networks, especially for
instances where the split configuration is smaller (1x2, 1X4, 2x2,
etc.).[1]
The PLC is a more recent technology. PLC splitters offer a better
solution for larger applications. 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.
