Single-Fibre 100 Mbps Transceiver

The Perle S-100-M1ST2D is a compact transceiver and media converter that bridges 10/100Base-T copper links to 100Base-BX-D single-fibre connections. It suits network engineers extending legacy Fast Ethernet segments over one fibre strand without replacing existing switches.

100 Mbps Throughput With DC Power

The unit handles 10 Mbps and 100 Mbps half- or full-duplex traffic on the copper side and 100 Mbps bidirectional flow on the fibre side. A 100-240 V AC regulated DC adapter is included, so the device runs directly from mains power without an external PoE injector or separate supply.

Upgrade From Copper-Only Uplinks

This transceiver replaces a copper-only uplink when distance or EMI immunity demands fibre, yet the backbone remains at Fast Ethernet speeds. The jump is worth it when a single-fibre run is cheaper than pulling a pair, but it will not serve links that require gigabit or multi-gigabit bandwidth.

Questions about this item

Will the 10/100Base-T port link with my older 10 Mbps switch?

Yes, the transceiver auto-negotiates down to 10 Mbps half or full duplex on the copper side so it works with legacy 10Base-T equipment.

How can I confirm the 100Base-BX-D fibre link is healthy after installation?

Check the SFP module’s Tx/Rx LEDs on the host switch; solid green on both sides means the single-strand bidirectional link is up at 100 Mbps.

Does the box include the fibre patch cord or only the transceiver and power adapter?

The package contains the S-100-M1ST2D transceiver/media converter and a 100-240 V AC regulated DC adapter; fibre patch cords must be purchased separately.
