The OSU optical splitter unit is a splitter based on planar optical waveguide technology. It is mainly used for communication trunk, MAN, LAN, private network, DPI, FTTX of PON, etc. Our 1*N, 2*N planar waveguide optical splitters are small and cost effective. They support a wide wavelength range (12601620nm) and can provide customers with low insertion loss and low polarization dependent loss.
