Description
Overview
GAOTek DWDM Mux or Demux is a high-performance DWDM mux or demux device, without the need for temperature stabilization. The planar-processed silica-on-silicon chips comprise arrayed channel waveguides to separate or combine multiple wavelengths. A thermal AWG s allow multiplexing and demultiplexing of DWDM signals over a wide operating temperature range, without the need for heater drive and monitoring electronics.
