Perle CM-100-S2SC40 Media Converter Module

The Perle CM-100-S2SC40 is a managed Fast Ethernet media converter module designed for network administrators extending copper links over single-mode fibre. It bridges 100BASE-TX RJ-45 connections to 100Base-EX 1310nm SC interfaces for long-distance data communication. The module supports both managed and unmanaged operation modes for flexible deployment. It suits infrastructure teams needing reliable fibre uplinks without replacing existing copper switches.

100 m copper and 40 km fibre reach

The RJ-45 port covers 100 m or 328 ft over twisted pair cabling per the 100BASE-TX standard. The single-mode SC port reaches 40 km or 24.9 miles at 1310 nm wavelength for campus or metro links. These fixed distance limits define the practical range for each media type. Signal loss beyond these thresholds will degrade the Fast Ethernet connection.

Single-mode SC capacity for extended runs

The 100Base-EX optics comfortably handle campus backbone and building-to-building spans up to the rated 40 km. Headroom exists for typical connector and splice losses within the link budget. The module runs out of reach when fibre attenuation or distance exceeds the 100Base-EX specification. It does not support multi-mode fibre or longer single-mode variants such as ZX optics.

Questions about this item

Should I choose the managed or unmanaged version of the CM-100-S2SC40 for my network?

The CM-100-S2SC40 supports both managed and unmanaged operation in one module, so you do not need to pick a separate version; configure it managed for SNMP control or leave it unmanaged for plug-and-play simplicity.

What does the 100 Mbps Fast Ethernet rating mean when the converter is installed in a live link?

It means the copper port runs at 100BASE-TX up to 100 m or 328 ft, while the fibre port carries 100Base-EX at 1310 nm over single-mode fibre up to 40 km or 24.9 miles.

Which interface standard does the SC connector follow, and what distance does it cap in practice?

The SC connector follows the 100Base-EX standard for 1310 nm single-mode fibre, capping the practical link distance at 40 km or 24.9 miles.
