Small rectangular fiber media converter module in metal casing with SC ports

Perle

Perle 05062060 CM-100MM-S2SC40 Fiber Media Converter

SKU CH-6H37-71DAQ

Converts 100BASE-FX multimode fibre to 100Base-EX single-mode fibre with SC connectors, reaching 2 km on multimode and 40 km on single-mode at 1310 nm

  • TypeData & Communication
  • Extends fibre links up to 40 km single-mode
  • Converts multimode to single-mode at 100 Mbps
  • Operates on 1310 nm wavelength for both fibres
  • Supports managed or unmanaged deployment modes
  • SC connectors on both sides for simple patching

What this converter does and who uses it

The Perle CM-100MM-S2SC40 is a managed Fast Ethernet fiber-to-fiber media converter module. It links a 100BASE-FX 1310 nm multimode SC segment up to 2 km with a 100Base-EX 1310 nm single-mode SC segment up to 40 km. Network engineers use it to extend campus or metro links across different fiber types.

Installation notes and common issues

The module fits a compatible Perle chassis and can run in managed or unmanaged mode. No software load is required for unmanaged operation; managed mode needs a supported management card in the same chassis. A frequent issue is mismatching the SC connector polish or wavelength, which breaks the link.

Practical limits of the Fast Ethernet fiber

The converter passes 100 Mbps traffic only; it does not support Gigabit or higher rates. Multimode reach is limited to 2 km and single-mode reach to 40 km at 1310 nm. Longer distances or higher bandwidths require different optics or a faster standard.

Highlights

  • Extends fibre links up to 40 km single-mode
  • Converts multimode to single-mode at 100 Mbps
  • Operates on 1310 nm wavelength for both fibres
  • Supports managed or unmanaged deployment modes
  • SC connectors on both sides for simple patching

Questions about this item

How can I verify the CM-100MM-S2SC40 is converting 100BASE-FX multimode to 100Base-EX single mode correctly after installation?

Check the module status LEDs for link and activity on both the SC multimode and SC single-mode ports; a steady link light on each confirms the 2 km and 40 km paths are active.

What comes in the box with the Perle CM-100MM-S2SC40 and what must I purchase separately?

The converter module itself is included; you must supply compatible SC patch cords for the 1310 nm multimode and single-mode fibers and a managed chassis if you want SNMP control.

Which version of the CM-100MM-S2SC40 should I choose for a 40 km single-mode link at 1310 nm?

Select the CM-100MM-S2SC40 model; it is the only variant listed that provides 100Base-EX 1310 nm single-mode SC connectivity up to 40 km.
