Network Technology Support

The Perle CM-100MM-S1ST20D is a managed Fast Ethernet fiber-to-fiber converter module. It supports 100Base-BX and 100Base-FX network technologies for extending links over single-mode or multi-mode fiber. This unit suits network operators and IT teams who need managed media conversion at 100 Mbps speeds.

Installation Notes

The module installs into a compatible Perle chassis to provide managed conversion services. Configuration is handled through the chassis management interface for remote monitoring. Ensure the chassis has an available slot and runs firmware that recognises this model. Mismatched firmware versions often cause the module to remain undetected.
