Products > Eclipse™> HVOA

Boston Applied Technologies' high speed variable optical attenuator (HVOA) has nano-second response speed and low insertion loss. It provides an ultimate solution for optical power stabilizing and limiting based on the high performance, high precision control circuits. HVOA can be set to maintain the output optical power at a constant level, countering the power fluctuations caused by PDL, channel add/drop, and other sources. The output power fluctuation level can be reduced to less than 0.01 dB. HVOA can also be used as an optical power limiter to protect the down streams. It can be offered either as a stand-alone optical power regulator (OPR) unit or as a module for system integration.
