    Eight-channel wdm

    The 8-channel wdm multiplexes or demultiplexes signals in dense wdm systems and uses optical interference filter technology that is optimized for thermal stability. Features include up to 30-dB isolation, channel spacing from 1.6 to 8 nm, narrow channel passbands from 0.8 nm, and polarization-dependent loss of 0.1 dB typical. Insertion loss is 0.6 dB per channel and wavelength tolerance is 0.1 nm. The device supports itu 200-GHz channel-spacing requirements.
