Dense wavelength-division multiplexer

The 100 Series dense wavelength-division multiplexer multiplexes optical signals on a single fiber. Featuring 100-GHz channel spacing, the dwdm collimates the incoming laser beams, combines them with a grating, and focuses them on the input end of a singlemode fiber. This optical assembly also works in the reverse direction to demultiplex different wavelengths onto many fibers. The input and output ports are available as pigtails or with fc/apc connectors. The multiplexer/demultiplexer is factory preset to match the wavelength and spectral band separation of dfb laser diodes (customer specified) centered on the itu grid. Insertion loss is <5.0 dB maximum, polarization-dependent loss is 0.5 dB maximum, and return loss is 60 dB minimum. The device is available in either 4 or 8 channels, or 16 channels by special order.
