The JDSU MTAS7 Switch Module Mainframe is a 19-inch rack-mountable chassis designed for automated optical signal routing and attenuation. This configuration pairs the MTA150 GPIB Control Cassette with eight MTAS7+1001FA1 optical attenuator modules, enabling precise, programmable control of optical power levels across multiple channels. The system supports IEEE 488.2 (GPIB) remote operation, front-panel keypad control, and SCPI-compatible commands with LabVIEW driver support for integration into automated test environments.
