Perle 100Base-BX SFP Transceiver

This Perle S-100MM-S1ST20D is a single-strand fibre transceiver built for 100 Mbps links. It suits network engineers extending Ethernet over one fibre strand. The module includes a regulated DC adapter that accepts 100-240v AC input. It is supplied new and ready for deployment.

100 Mbps Distance Limit

The 100Base-BX and 100Base-FX standards cap throughput at 100 Mbps. That ceiling fixes the practical bandwidth for any link using this transceiver. Longer fibre runs do not raise the speed; they only test the optical budget. Plan capacity around the 100 Mbps ceiling.

20 km Reach Decides Fit

The single specification that determines suitability is the 20 km reach on single-mode fibre. If your link spans less than 20 km this module works; if it exceeds that distance you need a different optic. No other parameter overrides this range limit.

Questions about this item

Should I choose the 100Base-BX or 100Base-FX version for my link?

The same module supports both 100Base-BX and 100Base-FX, so one unit covers either standard without a separate model choice.

What throughput will I actually see with the 100 Mbps rating in a live network?

Expect up to 100 Mbps full-duplex on the fibre segment, limited by the 100Base-BX/FX specification and the connected switch port speed.

Which connector and fibre type does the SFP interface use for this transceiver?

The SFP slot takes an LC duplex connector for single-strand or dual-strand multimode fibre, matching the 100Base-BX and 100Base-FX optics built into this module.
