Description
Overview
GAOTek DWDM MUX or DEMUX flat-top athermal (Arrayed Waveguide Grating) is a high performance DWDM mux or demux device operating on 100 GHz channel spacing without the need for temperature stabilization. The planar processed silica-on-silicon chips comprise arrayed channel waveguides to separate or combine multiple wavelengths. Athermal AWG s allow multiplexing and demultiplexing of DWDM signals over a wide operating temperature range, without the need for heater drive and monitoring electronics. These AWG offer low insertion loss, excellent channel isolation, ease of fiber handling, and long-term reliability in a compact package.
