Specification For plc Splitter

Description

PLC (Planar Lightwave Circuit) splitters are used to distribute or combine optical signals. It is based on planar lightwave circuit technology and provides a lowcost light distribution solution with small form factor and high reliability.

Fiber optical splitter is used to split the fiber optic light in to several part sat a certain ratio. The fiber optic splitter is an important passive component used in PON FTTX networks. There are mainly two kinds of passive FTTH optical splitters: one is the traditional fused type splitter as known as FBT coupler or FBT WDM optical splitter, which features competitive price; the other is the PLC splitter based on the PLC (Planar Light wave Circuit) technology, which has a compact size and suits for density applications.
