Abstract
A method and apparatus for performing an automatic power adjustment wherein a signal power level of an optical signal transmitted by an optical transceiver via an optical span to a far-end device is adjusted automatically in response to a determined span loss of the optical span to achieve a predetermined desired receive signal power level of the optical signal at the far-end device.
Claims20
A method for performing an automatic power adjustment,
- wherein a signal power level of an optical signal transmitted by an optical transceiver via at least one optical span to a far-end device is adjusted automatically in response to a determined span loss of said optical span to achieve a predetermined desired receive signal power level of the optical signal at the far-end-device.
An optical transceiver comprising a signal adjustment unit adapted to adjust automatically a signal power level of an optical signal transmitted by said optical transceiver via at least one optical span to a far-end-device in response to a determined span loss to achieve a predetermined desired receive signal power level of the optical signal received by said far-end-device.
An add/drop multiplexing node for an optical network comprising
- at least one network interface connected to a multichannel multiplexing/demultiplexing unit comprising a predetermined number of channel ports each being connected to an optical transceiver having a signal adjustment unit to adjust automatically a signal power level of an optical signal transmitted by said optical transceiver towards the respective channel port to provide a predetermined receive signal power level of the optical signal.
