Perle SMI-100-M1ST2U Transceiver

This Perle transceiver combines a 10/100Base-T port with a 100Base-BX-U SFP interface for single-fibre connectivity. It ships with a regulated DC adapter accepting 100-240v AC input. The unit is designed for media conversion between copper and fibre networks in enterprise environments.

Check Your Fibre Link Before Ordering

Verify that your existing infrastructure uses single-strand fibre with matching BX-U wavelengths for 100 Mbps operation. Confirm the switch or router slot accepts standard SFP modules and that the link distance matches the transceiver rating. Ensure a suitable AC outlet is available for the included power adapter.

Suits Single-Fibre 100 Mbps Links

This device suits administrators extending a 10/100 copper segment over a single fibre strand at 100 Mbps. It is not for networks requiring gigabit or 10-gigabit throughput, dual-strand fibre, or direct SFP+ cage installation without a media converter chassis. Buyers needing higher speeds or different wavelengths should look elsewhere.

Questions about this item

What comes in the box with the SMI-100-M1ST2U and is a separate SFP module required?

The package contains the SMI-100-M1ST2U transceiver and a 100-240v AC regulated DC adapter. No extra SFP module is needed because the fibre interface is built into the unit.

How do I choose between the 10/100Base-T and 100Base-BX-U interfaces on this model?

Both interfaces are fixed on this device; the copper port handles 10 or 100 Mbps Ethernet and the BX-U port handles 100 Mbps single-strand fibre, so you use whichever link the network requires.

What does the 100Base-BX-U rating mean for actual throughput when the transceiver is installed?

It delivers a 100 Mbps full-duplex fibre link over a single strand using the BX-U wavelength pair, matching the 100 Mbps copper side for consistent wire-speed performance.
