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
admin
A:
No. It needs to connect to the matching 1290nm channel port. Connecting it to a different wavelength port may cause no link or unstable transmission. By

A:
Yes, this LS-CW2910-40I module supports up to 40km transmission over single-mode fiber. The actual supported distance can vary depending on fiber loss, connector condition, and splice quality. By

A:
Yes. This industrial-grade 10G SFP+ CWDM module is suitable for LTE backhaul where a 10Gbps optical uplink is needed over single-mode fiber. It supports transmission up to 40 km and is a practical choice for outdoor LTE cabinets or remote sites with temperatures from -40°C to +85°C. Please make sure both connected devices support 10G SFP+ optics and that the CWDM wavelength matches the MUX/DEMUX channel. By

This transceiver module worked well for our base-station backhaul test setup. We needed 1290nm CWDM to fit the wavelength plan, plus wide-temperature operation for an equipment shelter with limited climate control. TX/RX power values in DOM were consistent across the modules we installed.

Good industrial CWDM 1290nm SFP+ module for the price. We had no issues with the LC duplex link or 10Gbps performance, but delivery took a couple of days longer than our project schedule expected. Product performance has been excellent so far.

For our data room expansion, we needed a CWDM SFP+ module that could handle longer metro-style fiber runs. This 1290nm unit performed as expected on a 36km route. The SFF-8472 diagnostics were visible in our monitoring tools, which saved time during turn-up.

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.

Bought several of these industrial 10G SFP+ CWDM modules for a remote aggregation project. The duplex LC connection was straightforward, and every unit linked at 10Gbps on our existing single-mode fiber. Great option when you need a 40km CWDM optical transceiver without moving to a more expensive platform.

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.
