Perle C-100Mm-S2St20 Media Converter

The Perle C-100Mm-S2St20 is a Fast Ethernet fiber-to-fiber media converter module. It connects 100BASE-FX 1310nm multimode ST links up to 2 km with 100Base-LX 1310nm single mode ST links up to 20 km. Network engineers use it to extend legacy 100 Mbps fiber segments across different cable types.

Passive module thermals and power

As a passive media converter module, the unit generates minimal heat and operates silently without fans. It draws power from the host chassis rather than a dedicated supply, keeping rack power budgets low. Normal use adds negligible thermal load to the enclosure.

ST connectors define cabling limits

The fixed ST connectors on both ports lock the installer into ST-terminated patch cords for multimode and single-mode runs. No SFP slots are present, so transceiver swaps or connector changes are not possible. Buyers needing LC, SC or hot-swappable optics must choose a different form factor.

Questions about this item

How is the Perle C-100Mm-S2St20 media converter installed in a chassis?

Slide the module into an available slot of a compatible Perle chassis until the connector seats firmly; the step often missed is securing the retaining screw so vibration cannot unseat the fibre links.

What maintenance or replacement will the Perle C-100Mm-S2St20 media converter need later?

Inspect and clean the ST connectors periodically; if link loss occurs after the 2 km multimode or 20 km single-mode budget is exceeded, replace the module.

What limit appears first on the Perle C-100Mm-S2St20 media converter under sustained use?

The 2 km reach on the 100BASE-FX 1310 nm multimode side is the first distance constraint; the single-mode side extends to 20 km.
