32 Ch x 100 GHz with custom Semi-Flat Top AWG Demux with SmartTherm Internal. With one LC connector at common port, four MPO(male) 8-fiber-array connectors at demux ports. There are 10 electrical pins (in one row) at bottom of the module, so pin-out definition should be same as the the 1st pdf datasheet link below. Test sheets were tested in 2005.

See datasheet of flat-top AWG demux at the 1st pdf link below, and the Gaussian AWG demux datasheet at the last pdf link

Note: The 32 Channels are not continousely. ITU channel 51, 50, 41, 40, 31, 30 do not exist in this demux, though demux channels are generally 100GHz-spaced.

General description for 100 GHz, Wideband (Flat Top) Arrayed Waveguide Gratings (AWG) :

JDSU 100 GHz,Wideband Arrayed Waveguide Gratings (AWGs) provide a price competitive, small-form-factor alternative to standard thin film based dense wavelength division multiplexing (DWDM).

JDSU AWGs are a product of advanced PLC fabrication capabilities, and are offered in both mux and demux configurations. The low cost and high performance make them the ideal solution for Metro and Long Haul DWDM applications.

JDSU AWGs can incorporate micro-controller-based internal temperature control (ITC) circuitry to allow stable alignment with the ITU grid. The optional ITC eliminates the need for external temperature control, and does not impact package dimensions.
