A:
Yes, absolutely. 1550nm is a standard channel on the ITU-T G.694.2 CWDM grid with a 20nm channel spacing. As long as your Mux/Demux filter unit has a dedicated 1550nm port available (and you match it with a 1550nm CWDM transceiver at the remote end), the LS-CW5510-40C will integrate seamlessly without causing crosstalk or interfering with your existing wavelengths.

Yes. This module is designed for single-mode fiber transmission and uses a duplex LC optical interface. OS2 fiber is commonly used for long-distance 10G CWDM links and is suitable for this 40 km module. By

A:
The stated specification is the operating case temperature of the module. Since internal switch heat and airflow can make the module case warmer than the surrounding air, it is important to leave sufficient thermal margin in high-density equipment. By

A:
The 40km rating is based on a standard optical link budget, not only the physical fiber length. Please include fiber attenuation, connector loss, splice loss, and CWDM MUX/DEMUX insertion loss when calculating the total link loss; this is the best way to confirm whether the link has enough margin.

Ordered these for a small data center expansion where we needed 10GbE over existing SMF. The duplex LC CWDM optics transceivers were individually protected, installed without issue, and showed stable optical power levels after burn-in.

This 10G SFP+ 1550nm CWDM module was installed for an indoor backhaul aggregation handoff over Duplex LC single-mode fiber. We specifically wanted CWDM optics rather than a generic short-reach module because the route had a longer patch-panel path and planned CWDM growth. The reported TX power range and receiver monitoring gave our NOC enough information to baseline the circuit. For commercial indoor cabinets operating within 0–70°C, it has been a straightforward, cost-effective choice.

Reliable 10GbE CWDM performance and fair value for a 1550nm 40km single-mode module. We would prefer more individual box cushioning for overseas bulk shipments, but the optics themselves arrived functional and tested well.

For a phased network expansion, we needed 1550nm 10G CWDM optics that could be deployed in batches without adding complexity for the operations team. These modules arrived ready for standard SFP+ installation, and our technicians could verify TX/RX optical information from the equipment during acceptance checks. The 40km single-mode fiber capability gives us flexibility for future remote-site links, even though our current runs are shorter. Overall, it is a practical optical module for indoor telecom rooms, equipment racks, and enterprise fiber infrastructure.

We deployed the LS-CW5510-40C CWDM module on a 10GbE campus backbone carrying virtualization, voice, and security traffic between buildings. Our single-mode route is well below the 40km maximum, but we selected the 1550nm CWDM optic to align with the existing wavelength plan. DOM was available immediately for checking transmit power, receive power, module temperature, and supply status during turn-up. After several weeks of normal traffic, the link has remained stable with no unexpected errors.

Our requirement was to carry 10G traffic across a leased dark-fiber route while preserving capacity for other CWDM wavelengths. This LS-CW5510-40C 1550nm SFP module fit the channel plan correctly and gave us the long-reach margin needed for the route. During commissioning, we used the module’s DDM information to verify optical conditions at both endpoints instead of relying only on link status. That saved time when documenting the circuit for handover.
