Abstract

A monitor device and method for monitoring operating conditions of a wavelength division multiplexed optical signal. The monitor device includes an optical engine for receiving the multiplexed optical signal and generating a plurality of demultiplexed optical signals. An array of optical detectors is disposed to receive the demultiplexed optical signals from the optical engine. The demultiplexed optical signals form spots on the array of optical detectors. At least one spot is wider than a center-to-center dimension spanning two optical detector elements in the array of optical detectors.
