Described herein is an optical channel monitor (1) including a protective housing (3), an input port (5) disposed in the housing (3) and configured for receiving at least one input optical signal (7) including one or more optical channels separated by wavelength. A wavelength configurable laser (9) is located within the housing (3) and is configured to provide an optical reference signal (11) at a first wavelength (λr). The laser (9) is adapted to scan across a range of wavelengths covering the one or more optical channels. An optical mixing module (13) is coupled to the input port (5) and the laser (9) for mixing the input optical signal (7) with the optical reference signal (11) to produce a mixed output signal. A receiver module (15) is configured to receive the mixed output signal and extract signal information indicative of at least the optical power of the at least one input optical signal at the first wavelength (λr).
An optical channel monitor including:
A optical channel monitor including:
A control system for an optical network having a plurality of interconnected nodes and at least one compensating module disposed between the nodes, the optical network adapted to transmit optical signals including one or more wavelength channels between the nodes, the control system including:
