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.

I needed the sfp cage quickly. Did not want to spend a whole lot of time trying to muddle through a complicated website looking for what I wanted. LINK-PP did just that. Up to this point I did not have a favorite site for my needs. Now I do.
