Datasheet

Overview

The MVOA-C2B08-SB0-M100-MLU is the 8-device, no-monitor configuration of the VIAVI MAP Series High Density Variable Optical Attenuator (mVOA-C2B), fitted with singlemode LC/APC connectors. The mVOA-C2B is a precision MEMS-based programmable attenuator built on a MEMS mirror design, offering low insertion loss, return loss and polarization dependent loss together with repeatable, stable attenuation.

The module is a single-slot, hot-pluggable cassette designed for MAP-300 generation mainframes. Up to eight modules fit in one 3U MAP-300 mainframe, allowing up to 96 independently controlled attenuators per chassis in configurations with 12 devices per module. The family succeeds the mVOA-C1 and is intended for client optic testing, coherent interface development, long-haul network stress testing, network emulation and silicon photonics development.

Operating mode

As a no-monitor variant, this model operates in Attenuator Mode: the desired attenuation is entered through the MAP user interface or by remote SCPI command and the module sets the output attenuation directly. Constant Power Mode and IL Mode require the in/out monitor variants of the series.
