As part of a regional communications infrastructure upgrade, we integrated these commercial-grade 10G CWDM optics into backhaul aggregation nodes located inside controlled indoor enclosures. Operating on the standard 1470nm channel, these modules seamlessly multiplexed with other CWDM wavelengths over a single dark fiber strand, eliminating the need for expensive new civil engineering fiber digs. Throughout a two-week stress test involving peak-hour data loads, optical return loss remained excellent and no signal degradation was recorded. Digital Optical Monitoring (DOM) metrics verified that laser bias current and transmitter output power remained completely stable. Highly recommended for network engineers needing standardized, cost-effective CWDM hardware for metropolitan and enterprise aggregation layers.

We deployed these LS-CW4710-20C 10G CWDM optical modules during a campus fiber consolidation project. The goal was to carry separate 10GbE services over existing OS2 single-mode fiber without adding new cable paths, so channel accuracy mattered just as much as link stability. Each 1470nm module was installed through a CWDM MUX/DEMUX pair, and all links came up at 10Gbps without CRC errors. We also used the SFF-8472 DOM information to record TX power, RX power, module temperature, and supply readings at handover. That made our acceptance testing faster and gave the operations team a useful baseline for future troubleshooting.

The module itself performs as expected and the 1470nm channel tested cleanly on our CWDM system. It is not the cheapest optic for a small project, but the diagnostics and 20km reach justify the spend when the fiber route requires it.

We used this 1470nm CWDM SFP+ transceiver to extend a 10GbE link between two buildings on our business campus. The 20km rating gave us enough headroom for the actual fiber route, and the Duplex LC ports made the swap straightforward. DOM values were visible right away, which helped during commissioning.

No issue with the optics at all — they were clean, sealed, and ready to deploy. The outer carton picked up some scuffs on the international route, which made the delivery look rougher than it was.

This was used for a remote radio-site backhaul upgrade where the actual route measured just under 19km, including patch panels and splices. The cooled EML transmitter and PIN receiver combination provided enough margin for our measured loss budget, while the 1470nm CWDM wavelength fit the available channel plan. We monitored optical levels through the switch during burn-in and saw stable values over continuous traffic testing. Since this is a 0–70°C commercial module, we placed it in a conditioned indoor communications cabinet rather than an exposed outdoor enclosure. For indoor telecom aggregation, it has been a dependable option.
