Description
Overview
GAOTek 40 channels DWDM with MUX and DEMUX functionality in 1U Rackmount is a high-performance DWDM mux/de-mux device operating on 100GHz 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 AWGs allow multiplexing and demultiplexing of DWDM signals over a wide operating temperature range, without the need for heater drive and monitoring electronics. These AWG offers low insertion loss, excellent channel isolation, ease of fiber handling, and long-term reliability in a compact package.
