- Boston Applied
Technologies Incorporated (BATI), a leading developer of light
intensity and polarization management products, today announced
the introduction of a high speed, high precision optical power
regulator/limiter (OPR). Based on a high performance Eclipse
variable optical attenuator (VOA) and high precision control
circuits, BATI's OPR provides an ultimate solution for optical
power stabilizing and limiting. The OPR uses the output from
an optical power monitor to control the VOA in a closed-loop
fashion. Because of the high-speed response of the VOA, the
OPR can be as fast as 30µ s. The product can be set to
maintain the output optical power at a constant level, countering
the power fluctuations and sparks caused by PDL, channel add/drop,
and other sources. The system can control the output power
level to better than ¡À0.01 dB. The products can also be used
as an optical power limiter to protect the down streams. The
complete unit can be either a stand-alone unit (as shown)
or a module for system integration.
