An 80km reach at 1550nm anchors the spec of the ONS-SE-2G-L2, a compatible stand-in for the Cisco module of the same designation on OC-48 LR2 links. It transmits over single-mode fiber and terminates in an LC/UPC connector, arriving with the coding a Cisco host expects already in place, so the module is recognized and the span returns to service without extra steps.

For extended OC-48 spans where the LR2 optic class is specified, this part keeps the 1550nm window and the 80km rating of the original, so the path engineering already on file does not need revisiting. It conforms to the MSA governing this form factor, with per-unit verification before dispatch. Long-term coverage comes via the GreenLights4Life® Limited Lifetime Replacement Warranty.
