Datasheet

Overview

The MVOA-C2B04-SB1-M100-MLC is a configuration of the VIAVI MAP Series High Density Variable Optical Attenuator (mVOA-C2B). It has four attenuator devices with input and output power monitors and singlemode fiber LC/PC connectors. The mVOA-C2B is a precision attenuator based on a MEMS mirror design. It replaces the earlier mVOA-C1 and is intended for client optic testing, next-generation coherent interfaces, long-haul network stress testing and silicon photonics development.

The module takes up one slot and is hot-pluggable. It works with all MAP-300 generation mainframes. A single 3U MAP-300 mainframe holds up to eight mVOA-C2B modules, which gives up to 96 independently controlled attenuators across the module family.

Operating modes

Because this variant has input and output monitors, it supports all three mVOA-C2B operating modes. In Attenuator Mode, the user sets the output attenuation directly from the UI or with remote SCPI commands. In Constant Power Mode, the monitors control the attenuator to hold a set output power while the input power changes. In IL Mode, a VIAVI calibration lets the user set the insertion loss between the input and output ports, so the 0 dB loss reference is known.
