Overview
VIAVI offers optical attenuators for field use and for laboratory and manufacturing test. The range includes the handheld SmartClass OLA-54 and OLA-55 optical level attenuators and the MAP series Variable Optical Attenuator module (mVOA-C1).
SmartClass OLA-54 and OLA-55
The SmartClass OLA-54 is designed for multimode fiber systems (50/125 μm fiber). The SmartClass OLA-55 is intended for system testing, installation, maintenance and production of single-mode fibers, and is available in PC and APC versions. Both instruments have a wheel for manual setting, absolute and relative attenuation setting, a graphical display, battery or AC adapter operation, and need no warm-up time.
MAP Variable Optical Attenuator (mVOA-C1)
The mVOA-C1 is a stepper motor and filter-based attenuator for the VIAVI Multiple Application Platform (MAP). It attenuates light through an expanded beam modified by a linearly variable neutral density filter. The module is available for single-mode or multimode fiber, supports several optical connectors, and comes in single, dual or quad configurations, all in single-slot modules. Up to 48 independently controlled attenuators fit in one 8-slot MAP chassis. The module is hot-pluggable and compatible with all current MAP-300 and MAP-200 chassis.
The mVOA has two operating modes. Attenuation mode changes the insertion loss of the module regardless of input power. Power mode sets the absolute output power and requires the internal power meter option; with input power tracking enabled, the attenuator adjusts automatically to keep output power constant. Three configurations are available: standard attenuator, attenuator with output tap, and attenuator with output power monitoring. Typical uses include amplifier testing, 100/400GE client optic testing and CWDM/DWDM test applications.
