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.

Questions about this item

What speed does the 100Base-TX interface actually cap at?

The RJ-45 port runs at 100 Mbps with a maximum frame size of 2048 bytes and a 100 m cable limit.

What mounting hardware and power connection does the DIN-rail case require?

It clips onto a standard DIN rail and uses a terminal block Combicon connector for an external power source.

How do I wire the single-strand SC fiber link so the TX and RX wavelengths match?

Connect the 1310 nm TX / 1550 nm RX side to a partner using the opposite 1550 nm TX / 1310 nm RX wavelengths.
