Datasheet

Overview

The VIAVI MVOA-C2B12-SB0-M100-MLU is a configuration of the MAP Series mVOA-C2B high-density variable optical attenuator module. This version has 12 attenuator devices, no input/output power monitors, and singlemode fiber LC/APC connectors.

The mVOA-C2B uses a MEMS mirror design. It offers low insertion loss, low return loss and low polarization dependent loss, with good repeatability, accuracy and long-term stability. It succeeds the mVOA-C1 and covers a wide wavelength range. Typical uses include client optic testing, next-generation coherent interfaces, long-haul network stress testing and silicon photonics development.

The module is a hot-pluggable, single-slot cassette for MAP-300 generation mainframes. A 3U MAP-300 mainframe holds up to eight modules, for up to 96 independently controlled attenuators. This suits network emulation test systems in lab and production environments.

Operating mode

The no-monitor variant runs in Attenuator Mode. In this mode the user sets the output attenuation directly, either from the user interface or with remote SCPI commands. Constant Power Mode and IL Mode need the in/out monitor variant.
