Industrial Media Converter

The Perle SR-100-SC20U-XT converts 100Base-TX copper signals to 100Base-BX single-strand fibre. It links RJ-45 equipment at 100 m with single-mode SC fibre runs up to 20 km. The unit operates from -40°C to +75°C for harsh environments.

DIN Rail Mount & Terminal Power

A DIN rail case snaps onto standard rails inside cabinets or enclosures. The Combicon terminal block accepts an external DC supply without a separate adapter. This mounting style keeps cabling tidy in industrial racks and panels.

Fast Ethernet Distance Limits

The link runs at 100 Mbps with a maximum frame size of 2048 bytes. Single-strand fibre uses 1310 nm TX and 1550 nm RX wavelengths over 20 km. Copper reach stops at 100 m, so longer spans require the fibre side.
