10/100Base-TX to 100BASE-BX Media Converter

The Perle SMI-110-S1SC20U converts 10/100Base-TX signals over RJ-45 copper to 100BASE-BX single-fibre single-mode using an SC connector. It supports transmission distances up to 20 kilometres or 12.4 miles. The unit operates with a 1310 nm transmit and 1550 nm receive wavelength pair. It is supplied with a USA power cord.

Distance and Frame Constraints

Copper links are limited to 100 metres or 328 feet, while the fibre side reaches 20 kilometres. The converter handles a maximum frame size of 2048 bytes, which restricts use with jumbo-frame networks. Single-fibre bidirectional operation requires matching wavelength equipment at the remote end.

Single-Fibre SC Wavelength Pair

This model uses a single SC port with 1310 nm TX and 1550 nm RX wavelengths for bidirectional traffic. The link will only function when paired with a device using the opposite wavelength assignment. Buyers needing dual-fibre connectivity or a different wavelength plan must select another converter.

Questions about this item

Should I pick the 20 km single-mode fiber version or a shorter-range model?

The SMI-110-S1SC20U covers 20 km over single-mode fiber with SC connectors; choose it when the link distance exceeds the reach of multi-mode alternatives.

What does the 10/100Base-TX rating mean for daily throughput?

It supports 10 or 100 Mbps on the copper side, so real-world throughput tops out at the 100 Mbps line rate of the RJ-45 port.

How does the 1310 nm TX / 1550 nm RX single-fiber interface affect deployment?

Bidirectional wavelengths on one strand halve the fiber count needed, simplifying cabling for the 20 km single-mode link.
