Assuming your passive MUX/DEMUX adheres to the standard 20nm CWDM channel grid, this module operates specifically on the 1530nm center wavelength. It will interface seamlessly with the designated 1530nm channel port, allowing you to run 10GbE traffic alongside other active channels on the same single-mode fiber pair. By

A:
A standard passive MUX/DEMUX assigns a specific physical port to each ITU wavelength, so only one 1530nm transceiver can operate on that specific channel per fiber pair. Additional bandwidth is added by populating the remaining MUX channels with optics tuned to different CWDM wavelengths across the 20nm spacing grid. By

The 10G 1530nm CWDM module itself works perfectly on our 16km SMF circuit, and DOM readings look normal. One outer shipping carton arrived with a dent, although the individual protective packaging kept the module safe.

We installed 12 LS-CW5310-20C modules as part of a campus CWDM overlay carrying 10GbE between core and distribution locations. Fiber distances ranged from 14.5 to 18km on single-mode fiber, with passive CWDM MUX/DEMUX units in the path. All links reached 10G without errors during burn-in, and the RX optical values stayed comfortably above the specified receiver sensitivity.
The DOM/DDM data was the main operational benefit for us. We pulled module temperature, supply voltage, laser bias, TX power, and RX power into our monitoring workflow, which gives us early visibility if a fiber connection starts degrading. For indoor cabinets and data room use, the 0–70°C commercial temperature range is appropriate.
