Fast-Ethernet Fiber Media Converter

The Perle CM-100MM-S2LC20 is a managed Fast Ethernet fiber-to-fiber converter module. It translates 100BASE-FX 1310 nm multimode signals on an LC interface to 100BASE-LX 1310 nm single-mode signals on an LC interface. Network engineers use it to extend links between multimode and single-mode infrastructure.

Multimode to Single-Mode Reach

The multimode side operates at 1310 nm with a 2 km reach over 1.2 miles. The single-mode side operates at the same wavelength with a 20 km reach over 12.4 miles. Dual LC connectors allow direct patching into existing patch panels or switches without adapters. Managed or unmanaged operation modes suit different monitoring policies.

Verify Wavelength and Distance Budget

Confirm that both link ends use 1310 nm optics and that the single-mode span does not exceed 20 km. Ensure the multimode segment stays within 2 km and that your switches or routers support 100BASE-FX and 100BASE-LX respectively. The module requires a compatible Perle chassis for power and management access.
