The EXFO SC Connector Adapter for the EPM-50 Power Meter (vendor part PMA-54, Millennium part 525495) swaps onto the EPM-50 to let techs measure optical power through SC connectors during fiber acceptance testing and troubleshooting. It's a direct add-on or replacement adapter, letting crews reconfigure a single power meter for different connector types on site rather than carrying separate meters. Built to EXFO's FiberBasix 50 platform spec, it drops in without recalibration. Keep a set of ST, LC and SC adapters on hand for the EPM-50 to match whatever connector a job calls for.
