In a multi-tenant office park, we used this 80km CWDM module to connect our core to a remote distribution building over existing SMF, running alongside other CWDM channels on a shared MUX/DEMUX. The 1350nm channel integrated cleanly with no crosstalk issues, and the duplex LC connectors made patching straightforward during our weekend changeover.

We deployed these 1350nm CWDM SFP modules across a 12-site metro ring for Ethernet backhaul, and over 60 days of continuous operation, the links stayed stable through daily traffic peaks and maintenance windows. The DDM telemetry helped our NOC spot a marginal splice early, and the commercial 0–70°C rating was perfect for our indoor MDF rooms and climate-controlled shelters.
