Product Identity

The Perle C-100-S1ST20D is an unmanaged Fast Ethernet converter module built for network transceivers. It bridges 10/100Base-T copper links to 100Base-BX-D single-strand fibre connections in enterprise or industrial environments.

Installation Notes

The module slots into a compatible chassis or switch bay without software configuration because it is unmanaged. Installers must verify that the host equipment accepts this form factor and that the single-fibre BX-D wavelength pair matches the link partner.

Target Users

This suits network engineers extending copper segments over single-strand fibre where managed features are unnecessary. It is not for teams needing Layer 2 management, monitoring capabilities, or multi-mode fibre support.

Questions about this item

How do I verify the 10/100Base-T link is active after connecting the module?

Check the port LEDs on the connected switch; a steady or blinking link light at 100 Mbps confirms the 10/100Base-T interface is passing traffic.

What comes with the C-100-S1ST20D and what must I source separately?

The module itself is supplied; you must provide a compatible switch or media converter chassis with an open SFP slot and a single-strand fibre patch cord matched to the 100Base-BX-D wavelength.

Which version suits a 20 km single-fibre run at 100 Mbps?

The C-100-S1ST20D is built for 100Base-BX-D over one fibre strand up to 20 km, so choose this model when that distance and wavelength pairing are required.
