Does this 10G DWDM C20 1561.41nm module require a specific wavelength MUX DEMUX channel to operate properly?

Yes, it operates on ITU-T 100GHz C-band Channel 20 (1561.41nm). It can be used in a point-to-point link with a matching 1561.41nm transceiver or connected to Channel 20 of a DWDM MUX DEMUX multiplexer.

Can I monitor optical transmit and receive power in real time using DOM on this transceiver?

Absolutely. The optic features built-in Digital Optical Monitoring (DOM/DDM) per SFF-8472 standards, allowing you to track TX/RX optical power, operating temperature, laser bias current, and supply voltage directly through your switch software.

Is the LINK-PP LS-DW2010-40I optic truly rated for industrial operating temperatures, and can it be used in unheated outdoor cabinets?

Yes, this industrial transceiver is specifically designed for harsh environments with an extended operating temperature range of -40°C to 85°C (-40°F to 185°F), making it ideal for unconditioned outdoor cabinets and roadside enclosures.

Deployed this industrial 10G DWDM module in an unconditioned roadside cabinet. Operating temperature ranged from sub-zero nights to hot afternoons, but the C20 1561.41nm wavelength stayed rock solid with zero thermal drift. :)
