At the physical layer, both wavelengths share an identical 9µm single-mode fiber core diameter, making their insertion loss sensitivity to microscopic contamination functionally equal. To maintain your link budget margins, we strictly recommend scoping and cleaning the ferrule tips with an optical click-cleaner immediately prior to insertion. By

Works great, but make sure your Mux matches 1370nm. The product description is clear, but one of our junior installers accidentally tried to patch this into a 1310nm channel on our CWDM Mux. Obviously, the link didn't come up until we moved it to the correct 1370nm port. Excellent 20km optical module, just verify your wavelengths!

Great transceivers, but shipping took an extra day. The LS-CW3710-20C 10G modules themselves work perfectly in our switches — recognized immediately and DDM is fully functional. However, the express courier delayed the delivery by 24 hours, which pushed our scheduled maintenance window back slightly. Product is 5 stars, shipping is 3 stars.

Slightly delayed tracking info update. The sales team was helpful, but the tracking number didn't update in the system until two days after shipment. Had me worried our network upgrade timeline would slip. Thankfully, the package arrived right on schedule and the 10G SFP+ CWDM modules are working beautifully.

Excellent choice for campus network core distribution upgrade. Our university network team recently overhauled the distribution layer across 4 separate campus locations. We leveraged these 10G SFP+ CWDM 1370nm transceivers to consolidate traffic into our primary data center over a 15km single-mode fiber ring. The duplex LC interface provides clean, low-insertion-loss connectivity. Even with multiple intermediate optical patch panels, the signal margin remains highly conservative. This deployment has significantly reduced our packet jitter during peak student registration hours. Highly recommended for any institutional IT infrastructure overhaul.
