Managed Fast Ethernet Media Converter

The Perle SMI-100-S1SC20U connects a 100BASE-TX copper link to a 100BASE-BX single-fibre single-mode link. It is built for network teams that need to extend a Fast Ethernet segment over one strand of fibre. The SC connector carries 1310 nm transmit and 1550 nm receive wavelengths. This unit suits managed infrastructure where remote configuration and monitoring are required.

Distance and wavelength constraints

The fibre port reaches 20 km or 12.4 miles on standard single-mode cable. The copper port is limited to 100 m or 328 ft per 100BASE-TX rules. Only the stated 1310 nm TX and 1550 nm RX wavelengths are supported; mismatched wavelengths will not link. No other distance, connector type or wavelength option is available on this model.

Single-fibre bidirectional design

This converter uses a single SC simplex connection for both transmit and receive. It therefore requires a matching converter with the opposite wavelength pair at the far end. Installations that already use duplex fibre or a different connector cannot use this unit without rewiring. The fixed wavelength assignment means the two ends are not interchangeable.

Questions about this item

Which fibre reach should I select for a link up to 20 km?

The 20 km single-mode version with 1310 nm TX and 1550 nm RX wavelengths covers distances up to 20 km or 12.4 miles on a single SC fibre strand.

What does the 100BASE-TX rating mean once the converter is installed?

It provides a 100 Mbps copper port on an RJ-45 connector with a 100 m or 328 ft maximum cable run to the connected device.

How does the single-fibre SC interface limit the connection in practice?

The bidirectional single-strand SC link uses 1310 nm for transmit and 1550 nm for receive, so both ends must use matching wavelengths and the fibre path cannot exceed 20 km.
