With LC/UPC fiber adapters. See ITU grid defination in the 2nd pdf link below. You need apply external temperature controller on this DEMUX. The set temperature is 70.8 C degree. There is 10-pin electrical interface at the bottom of module. We verified that pinout info is same as the 2nd pdf link below. Basically you need connect two heater pins and one pair of RTD temperature-sensor pins to your temperature controller (many types of temperature controllers support RTD temperature sensor). Then you can easily set demux to required temperature (about 70.8 C).
