Perle C-100-M2ST2 transceiver for copper-to-fiber

The Perle 05051200 SFP transceiver converts 10/100Base-TX copper signals to 100Base-FX multimode fiber. It is built for network administrators who need to extend legacy Fast Ethernet segments beyond copper distance limits. The module fits a high-density Perle Media Converter Chassis and uses an ST duplex connector for the fiber side.

1.24 mile reach with ST duplex and RJ-45

The link runs up to 1.24 mile over multimode fiber, giving ample headroom for campus or building-to-building runs. Auto-Negotiation and Auto-MDIX handle speed and crossover automatically on the RJ-45 port. The 100 Mbps ceiling means the module cannot serve Gigabit or 10 Gigabit segments, so it stops at Fast Ethernet throughput.

Fits Perle chassis, frees copper distance limits

Installation requires an available slot in a Perle Media Converter Chassis, which supplies power and management. The transceiver replaces a copper patch cord, freeing the design from the 100 metre UTP restriction. It does not operate standalone and needs the matching chassis infrastructure to function.

Questions about this item

Will the 10/100Base-TX RJ-45 port auto-negotiate with my older 10 Mbps switch?

Yes, the module supports Auto-Negotiation and Auto-MDIX on the RJ-45 port so it will link automatically with legacy 10 Mbps equipment.

How can I confirm the 100Base-FX ST duplex link is healthy after installation?

The Link Pass-Through and Far End Fault features propagate link status end-to-end, letting you verify the fiber path from either side.

Does the 05051200 ship with the ST duplex patch cable or must I buy it separately?

The transceiver includes only the module itself; ST duplex fiber patch cables and a compatible Perle Media Converter Chassis are purchased separately.
