Sumitomo Electric offers optical fiber couplers and splitter modules (for multiplexing/demultiplexing or branching optical signals), optical filters (for selectively multiplexing/demultiplexing light of specific wavelengths), WDM filters (for multiplexing/demultiplexing broadcasting signals and telecommunications signals), etc.
Optical splitter modules
These module products can meet changes in future demand. Modules can be installed in a 19-inch rack-mount chassis.
These filters can achieve multiplexing/demultiplexing of telecommunications signals (1,550 nm) and broadcasting signals (1,310 nm, 1,490 nm) with low insertion loss and high isolation.
