Fiber optic splitter is an important component in FTTx and PON architectures, enabling multiple users to share the optic network. The most common types of optic splitters are FBT (fused biconic taper) splitter and PLC (planar lightwave circuit) splitter. PLC Optic Splitter PLC Splitter is an integrated waveguide optical power distribution device based on quartz substrate, featuring small size, wide range of working wavelength, high reliability and good spectral uniformity, especially suitable for passive optical network (EPON, BPON, GPON, etc.) to connect the local end and terminal equipment and achieve optical signal splitting. https://www.glsun.com/article-p90-differences-between-fbt-splitter-and-plc-splitter.html
