VIAVI MAP Series mOSX-C1 Cross Connect Optical Matrix Switch Module

The VIAVI MAP Series mOSX-C1 is a cross connect optical matrix switch module and part of the VIAVI test automation switch portfolio. It acts as a test path manager: multiple test paths can be connected across the switch fabric at once, so test processes can run in parallel.

The mOSX is a non-blocking, bidirectional matrix switch with an any-port to any-port connection fabric. It supports both symmetric MxM topologies, such as 8x8, and asymmetric topologies, such as 4x12, so the switch can be reconfigured on demand. Ports can be allocated as inputs or outputs as needed. Connections can be pre-configured without light present. They stay in a blocking state until activated, and connections can be made or broken without affecting other connections.

Switching principle

The switching engine uses compact piezoelectric actuators to align the signal path through expanded beam optics. A capacitive sensor matrix measures the position of the collimating lens to keep the alignment stable and repeatable. Connections are held even when no light is present. Reflective optics fold the switch engine so that each fiber can connect to every other fiber. As a result, software can set up the same hardware in different configurations: for example, a 16-port switch can run as a dual 4x4, 8x8, 7x9, 6x10 or 1x15.

Control and platform

The module is controlled through a SCPI remote interface or the MAP Series graphical user interface. Ports can be given logical names, and individual connections can be disabled or re-enabled. As a software option, the switch can be restricted to a defined MxN topology. The mOSX belongs to the LightDirect switching module family and works with current MAP-300 and MAP-200 chassis. It can be paired with MAP-Series mOSW modules to build larger switching systems.
