I run a specialized homelab with a 10G NAS backbone, but needed these 1.25G Simplex SC transceivers for bridging remote outdoor PoE security cameras. They just work, with no connection drops over 8km SMF.

We strictly require industrial-grade optics for our cell tower backhaul. This -40 to 85°C rated 1G BiDi module survived our environmental chamber stress tests perfectly. DOM readings stayed highly consistent throughout.
