Fusion JMEP

Fusion JMEP is a powerful micro Ethernet probe for Ethernet and IP performance assurance.

The VIAVI JMEP smart SFPs are gigabit Ethernet smart SFP transceivers that reduce the need for additional network instrumentation. There are two transceiver varieties, a 1 Gbps JMEP3 and a 10 Gbps JMEP10, that seamlessly deploy inline into existing network devices. They provide network operators and service providers with remote test points that enable performance-assured service delivery and increase the value of existing network infrastructure.


  • Simple to use, easy to deploy in existing network SFP ports
  • Turns network ports into service-assurance tools, enabling Ethernet operation, administration, and maintenance (OAM) for any 1GE or 10GE
  • Simplifies test and troubleshooting procedures to reduce equipment upgrades, truck rolls, and mean time to repair (MTTR)
  • Compatible with the VIAVI T-BERD®/MTS test portfolio and the and award-winning Fusion EtherASSURE™ centralized test solution
  • Monitors across mobile-backhaul networks without additional instrumentation


  • Turn up, test and troubleshoot, and monitor key network performance in mobile backhaul, business services, and cloud networking services.
  • Instrument network demarcation points using Fusion JMEP SFP probes, isolating network boundaries, without deploying additional network devices or consuming additional space and power.
  • Add consistent, end-to-end standard based test and monitoring to any network device, without taxing network performance.

Key Features
