Optical combiner and splitter Nx series

for the optical industrycompact

Product Overview
Planar lightwave circuit (PLC) splitter is an integrated waveguide optical power distribution device based on a quartz substrate. It performs optical coupling, branching and distribution in fiber networks and is widely used as a passive splitting element in access and distribution networks such as EPON, GPON and BPON.

Product Features

• Wide operating wavelength range: 1260–1650 nm to support diverse optical communication scenarios.
• Low insertion loss: engineered to minimize insertion loss across split ratios for reliable link budget planning.
• Good uniformity and low polarization-dependent loss (PDL): consistent output levels across channels with low PDL for stable signal quality.
• Multiple connector and packaging options: available with various connector types and 1U 19" rack packaging to fit different installation environments.

Product Application

• Optical fiber sensing
• Optical cable network systems
• Telecommunication access networks (EPON/GPON/BPON)
• LAN and CATV distribution
