Perle CM-100MM-S2ST20 media converter

The Perle CM-100MM-S2ST20 is a managed Fast Ethernet fiber-to-fiber converter module designed for network infrastructure. It bridges 100BASE-FX 1310 nm multimode signals over 2 km to 100Base-LX 1310 nm single mode signals over 20 km using ST connectors. The module supports both managed and unmanaged operation modes for flexible deployment.

Network links needing 20 km single mode reach

This converter suits operators extending multimode segments into longer single mode runs up to 20 km at 100 Mbps speeds. It is not suited for links requiring multimode distances beyond 2 km or for Gigabit and higher bandwidth requirements. Installations needing different connector types or wavelength configurations should consider other options.

20 km single mode transmission distance

The defining specification is the 20 km reach on the 100Base-LX 1310 nm single mode port. This distance determines whether the module can span the required link between network nodes. Verify that your link budget and physical path fall within this 20 km limit before deployment.

Questions about this item

How do I confirm the CM-100MM-S2ST20 is operating correctly after installation?

Check the module LEDs for a solid link light on both the 2 km multimode side and the 20 km single-mode side; the management interface will also report 100BASE-FX and 100BASE-LX sync at 1310 nm.

What comes in the box with the CM-100MM-S2ST20 and what must I purchase separately?

The converter module itself is included; ST patch cords for the multimode and single-mode fibres, a compatible chassis and power supply are sold separately.

Which version should I choose if I need to connect 2 km multimode fibre to 20 km single-mode fibre?

Select the CM-100MM-S2ST20; it converts 100BASE-FX 1310 nm multimode ST 2 km to 100BASE-LX 1310 nm single-mode ST 20 km.
