Key Features
The Multiple Application Platform (MAP) Variable Optical Attenuator
(mVOA-A2) is optimized for the industry-leading JDSU MAP-200 platform.
Based on the previous-generation Multiple Application Platform (MAP), the
MAP-200 is the first photonic layer lab and manufacturing platform that is LAN
Extensions for Instrumentation (LXI)-compliant by conforming to the required
physical attributes, Ethernet connectivity, and interchangeable virtual instrument
(IVI) drivers. The MAP-200 platform is optimized for density and maximum
configurability to meet specific application requirements in the smallest possible
foot print.
The mVOA-A2 is a stepper motor and filter based attenuator that takes advantage
of the latest available technologies to provide the highest performance optical
power level control solution with the lowest optical impairments.
– Ultra low insertion loss to minimize loss budget utilization
– High accuracy and high repeatability to reduce measurement uncertainty
– Fast transition speed to reduce testing time
– Flat spectral response to reduce wavelength dependent uncertainty in
multi-wavelength applications (CWDM, DWDM)
– Low backreflection to reduce instabilities due to reflected light
– Optional built-in wavelength calibrated power meter reduces the uncertainty
by reducing external connections
– High input power capability for EDFA testing and multi-wavelength applications
• Ultra low insertion loss (<1.0 dB) and outstanding
spectral uniformity
• Fastest transition speed in its class (up to 25 dB/s)
• Configurable by user at time of order (fiber type, density,
built-in options, high power option)
• Optional built-in power monitor provides comprehensive
closed-loop power control settings
• Optional higher power capability can withstand up to 2W
input power for single-mode fiber (500 mW for MMF)
• Can be automated when used with MAP-200
LXI-compliant interfaces and IVI drivers

The MAP Variable Optical Attenuator is a hot-pluggable cassette designed for use within the Multiple Application Platform
(MAP). The MAP is a general purpose high density test and measurement platform for lab or production environments. Up
to 16 independently controlled attenuators can be installed in a single MAP chassis.
