Fast Ethernet Media Converter

The Perle C-100-S2St20 converts 100BASE-TX copper signals to 100Base-LX single-mode fibre. It connects an RJ-45 port to an ST connector operating at 1310 nm. Network engineers use it to extend LAN segments beyond standard copper limits. The module supports link distances up to 20 km.

ST Connector and Single-Mode Fibre

The ST bayonet fitting locks securely into patch panels or wall outlets. Single-mode fibre carries the 1310 nm wavelength over 20 km or 12.4 miles without repeaters. Copper side reaches 100 m or 328 ft from the switch. This combination suits campus backbone links and building-to-building runs.

Verify Fibre Type and Port Compatibility

Confirm your existing cabling is single-mode with ST terminations before ordering. Check that the far-end device also uses 100Base-LX at 1310 nm. Ensure the switch port negotiates 100 Mbps full-duplex to match the converter. Power requirements and mounting hardware are not detailed in the supplied data.
