Description
Overview
GAOTek 48channel 100ghz athermal DWDM for solid optical transmission dense wavelength division mux/demultiplexer modules are part of a series of high-performance products based on silica-on-silicon planar technology and a unique athermal packaging design requiring no electrical power, software or temperature control for a completely passive DWDM solution. This product range offers a combination of shallow loss and high channel isolation, long-term reliability, long-term reliability and low cost per channel for 48-channel, 100GHz solutions. Each module can perform Mux and Demux functions. Different input and output fibers, such as SM fibers, MM fibers and PM fibers can be selected to meet different applications.
