FN-TRAN-SFP+ER Fortinet Compatible SFP+ ER Transceiver

For extended-reach 10G links that have to stretch past what standard optics cover, the FN-TRAN-SFP+ER fills the ER role in the SFP+ form factor. Its ER classification marks it for the longer single-mode routes between sites, and it slots into a standard SFP+ cage as a straight optical upgrade for those paths. The module returns DDM diagnostics to the host so the link stays observable across the distance, giving operators the same telemetry they would expect from the OEM part it stands in for.
