A:
Yes, provided that your CWDM MUX/DEMUX has a dedicated 1290nm channel. The 1290nm module can run alongside 1310nm and 1330nm CWDM channels on the same single-mode fiber pair because each channel uses a different wavelength. Use a matching 1290nm CWDM module at the far end, and check the total link loss, including fiber, connectors, splices, and MUX/DEMUX insertion loss. By

Our team evaluated this industrial 10G SFP+ CWDM transceiver for an outdoor utility communications network. The important requirements were the 1290nm wavelength, Duplex LC interface, 40km reach, digital optical monitoring, and operation from -40°C to 85°C. We ran continuous traffic, link-flap tests, and environmental cabinet checks, and the modules remained stable with no unexpected alarms. The diagnostic values were readable through our standard management workflow, including temperature, voltage, laser bias, transmit power, and receive power. It is a strong fit for industrial switching, remote cabinets, and long-distance 10GbE uplinks.

We used this LS-CW2910-40I 1290nm CWDM SFP+ in a small business park network with roughly 31km of single-mode fiber. The 10G link has stayed stable through normal daytime heat and overnight temperature swings. DOM monitoring is useful for checking optical power before a minor loss becomes a service call.

We deployed twelve LS-CW2910-40I modules across a campus-to-industrial-site fiber refresh. The longest route was just under 38km on existing ITU-T G.652 single-mode fiber, with several patch-panel transitions along the way. Link establishment was immediate at 10Gbps, and post-install monitoring showed stable optical levels well within the module’s stated TX and RX range. The DOM data helped our NOC compare receive power across sites and quickly identify one dirty connector that was not related to the optic. For a 1290nm CWDM SFP+ 40km application, these have been dependable in production.

We installed a matched pair on a fiber route connecting two server rooms through a metropolitan dark-fiber segment. Total optical distance was 37.4km, and the path included multiple LC patch points, so DOM visibility was a must. The modules held a clean 10G connection during backup windows and high-throughput replication tests, while receive levels stayed comfortably above the sensitivity threshold. We also moved one optic through several compatible SFP+ ports during commissioning; it was recognized normally each time after standard configuration. Great field result for a 40km single-mode CWDM deployment.

For a private LTE/5G-style backhaul lab, we needed a 10Gbps optical module compatible with CPRI and eCPRI-oriented deployment requirements, not simply a generic data-center optic. This industrial 1290nm CWDM SFP+ met the required SFP+ MSA, SFF-8431, and SFF-8472 diagnostic expectations and ran reliably on the 32km SMF test route. We monitored both ends during heavy traffic and simulated equipment-room temperature variation, with stable optical power and no observed CRC increase. The 40km budget provides useful margin for future route changes.
