I'm a field engineer handling mobile backhaul, and these LS-CW351G-40C optical modules have been workhorses. We use the 1350nm CWDM channel to carry 1G backhaul between base stations and the aggregation site over roughly 30km of single-mode fiber. The DFB CWDM transmitter holds a rock-steady optical signal, and the PIN receiver's -24 dBm sensitivity gives solid margin on the longer spans. The duplex LC connectors seated cleanly, and the module locked into our devices without any EEPROM complaints. For a 40km CWDM SFP, this is dependable kit I'd trust on a live network.
