No, receiver sensitivity is only one baseline metric. To guarantee a stable 80km link, you must calculate the full optical power budget (minimum Tx power minus Rx sensitivity) and ensure it exceeds your total path attenuation. Your calculation should factor in fiber loss per kilometer, splice and connector insertion loss, passive MUX/DEMUX loss, chromatic dispersion penalties, and a 2–3 dB safety margin for fiber aging. by LINK-PP Technical Support
Yes, it is engineered for metro and long-distance backhaul, supporting up to 80km over single-mode fiber at data rates up to 10.7Gbps. Before deployment, please verify that your total span loss, host platform compatibility, wavelength channel plan, and remote-end optics align with the link's optical budget. by LINK-PP Technical Support
Different DWDM wavelengths may be used in the same system when the MUX/DEMUX supports the assigned channels. C56 is 1532.68nm, C57 is 1531.89nm, and C58 is 1531.12nm. Confirm the channel grid and port mapping before deployment. by LINK-PP Technical Support
The industrial temperature specification is helpful for sites with limited climate control. The actual host equipment still needs to support the expected operating conditions.

The module's 80km rating is relevant to our regional network design, but we still calculate the actual loss across the fiber, connectors, splices, and passive components. The listed -23dBm receiver sensitivity is another useful input for that assessment.
