Transition Networks

Transition Networks manufactures copper-to-fiber media converters, industrial Ethernet switches, SFP modules, and network adapters specified in building automation, video surveillance backhaul, transit systems, and industrial control networks. The Transition Networks catalog is engineered in Minnesota since 1987 — a specialist in the exact fiber-over-copper and copper-over-fiber interconnects that bridge IP cameras, access control readers, and legacy serial devices onto modern Ethernet infrastructure.

We stock the full Transition Networks catalog — Stand-Alone and Mini-Converter media converters, ION 19-inch chassis for multi-port media conversion, SGFEB industrial hardened switches, SISGM1040 managed gigabit switches, SBFTF SFPs and XFP modules, SESPM PoE+ injectors for perimeter surveillance, and the full range of serial-to-Ethernet interface converters — at authorized dealer pricing. Transition Networks was acquired by Lantronix in 2021 but continues to manufacture and support the full brand catalog under the Transition Networks name. Every product ships with the manufacturer warranty and Lantronix's U.S.-based technical support network, and our engineers help with copper-to-fiber distance calculations, PoE budget planning for extended camera runs, industrial hardened specifications for harsh environments, and ION chassis configuration for multi-site deployments.
