OZ Optics has successfully combined its expertise in variable attenuators with its optical power monitor technology to develop the OPR series of optical power regulators. These systems allow to maintain the output optical power from a fiber optic system at a constant level, countering changes caused by PDL, reduced amplifier gain, or other sources.

The optical power regulators use the output from an optical power monitor as feedback to control an attenuator. Simple controls allow the user to enable or disable the feedback circuit, monitor the signal intensity, and control the output power through the fiber. The systems can maintain output power levels constant to better than ±0.1 dB, with millisecond response speed.

Optical power regulators are used wherever one has an unstable output from an optical fiber and one needs a more stable signal. They are ideal for power stabilization in DWDM networks, where changes in power can produce transmission errors. The complete unit is available either as a miniature module that can be integrated into other devices, a stand-alone module for testing, or as a rack mountable unit for optical networks.
