Optical Cross Connect

Physical Layer Optical Switches

Finally path switching has reached its ultimate form. MRV's Optical Cross Connect (OCC) eliminates Optical Electronic conversion as well as the need for physical (re-)configuring of networks. Its predecessor, MRV's Media Cross Connect, provided auto configured networks for test purposes for networking Laboratories from major manufacturers all over the world. Now it has been proven to be suitable for many other applications. As it descendant, the OCC is the ultimate step in auto configuring networks. Fully SNMP manageable, the OCC can re-configure paths in milliseconds, based on a pre-configured set of rules.

The center of OCC architecture is a three dimensional Micro-Electric-Mechanical (3D-MEMS) switching matrix. This technology allows transparent switching of single mode fiber connections in less than 20 ms with a typical insertion loss of 2.0 dB, and it makes the OCC ideal for:

  • Maintaining optical attributes when testing
  • High density 10 Gbps applications
  • 40 Gbps protocols
  • Non-standard protocols
  • WDM applications with parallel wavelength switching
  • Burst mode signals as in PON applications


  • Logical Cable Management — Using software commands allows non-blocking, any port to any other port, bidirectional or unidirectional mappings. The MCC allows one to any multi-point broadcast mapping, and fiber channel arbitrated loop (FCAL) topologies.
  • Modular Architecture — The MCC is available in 72, 144 and 288 port configurations that support any protocol or media within a single chassis. All service blades are interchangeable and hot swappable between the chassis types. The OCC is scalable to 320 bidirectional ports in 8 port increments.
  • Wide range of data rates and media types — The MCC supports protocols from T1/E1 to Fiber Channel to 10 Gig Ethernet. Different media types, including copper cable and pluggable transceivers such as SFPs and XFPs are supported in the same chassis. The OCC supports single mode fiber data rates to 40Gbps and above.
  • Wire-Once Technology — Once the lab network and equipment is connected to the MCC or OCC, all connections and configurations are done using software commands. Changing a test topology is accomplished by a simple mouse click.
  • Media Conversion — With the MCC, mapping a copper input to a fiber output eliminates the need for standalone converters and maximizes the use of test equipment equipped with one type of connection.
  • Increased Lab Efficiency and Productivity — Topologies can be changed and stored using a web-based GUI, or by using an industry-standard interface, tests and topologies can be scripted and executed 24/7. Inventory management/tracking is simplified as equipment is not physically moved to perform tests.
  • Decrease Capital Expenditures — By sharing expensive test equipment and fixed test beds, capital equipment costs can be minimized without compromising capabilities.
  • Standard Software Interfaces
