MRV's physical layer switches are scalable, OSI layer 1 switches that allows users to connect any port to any other port within the system using a non-blocking matrix. The Media Cross Connect is an optical/electrical/optical (OEO) switch used for data rates and media up to 10Gbps. The Optical Cross Connect is an all optical (OOO) switch for single mode fiber rates up to 100Gbps. Deploying these switches in a lab environment allows test commitments to be met without compromising quality or responsiveness, or increasing capital or operational expenses.
