Perle SMI-110-S1ST20D Transceiver Media Converter

The Perle SMI-110-S1ST20D is a new SFP transceiver and media converter module that supports 10/100Base-T copper and 100Base-BX-D single-fibre optics. It includes a 100-240v AC regulated DC power adapter for standalone operation. Network engineers use it to bridge twisted-pair and fibre segments in managed infrastructure.

Installers extending legacy Fast Ethernet links

This module suits teams maintaining 100 Mbps links where bidirectional single-strand fibre is required. It is not suited for gigabit or faster backbone links, for multi-mode fibre plant, or for switch slots that accept only plug-in SFPs without external power. Buyers needing higher throughput or different fibre types should look at other form factors.

100Base-BX-D single-fibre interface

The defining specification is the 100Base-BX-D optical interface, which transmits and receives on a single strand at 100 Mbps. The matching BX-U module must be deployed at the far end to complete the wavelength pair. Confirm the link distance and wavelength plan before ordering.

Questions about this item

How much power does the 100-240V AC adapter draw when the transceiver runs continuously?

The included 100-240V AC regulated DC adapter powers the SMI-110-S1ST20D for continuous operation.

Which existing network equipment must I have to use the 10/100Base-T copper interface?

You need a switch or router port that supports 10/100Base-T over twisted-pair copper cabling.

Will the 100Base-BX-D single-fibre link work with older 100Base-FX multi-mode gear I still run?

No, 100Base-BX-D uses single-mode fibre with bidirectional wavelengths, which is incompatible with 100Base-FX multi-mode interfaces.
