Abstract
A method and system for controlling extinction ratio in an optical network is disclosed. A first optical transceiver sends modulated light to a second optical transceiver and a digital measurement of a signal parameter reflecting the optical power levels of the received modulated light is taken. The modulated light sent by the first optical transceiver is adjusted in accordance with the digital measurement.
Claims56
A method of controlling extinction ratio in an optical network configured for transmitting and receiving network data, the method comprising the steps of
- providing a first optical transceiver configured for sending modulated light,
- providing a second optical transceiver configured for receiving modulated light,
- taking a digital measurement of at least one signal parameter reflecting the optical power levels of the received modulated light, and
- adjusting the modulated light sent by the first optical transceiver in accordance with the digital measurement.

An optical network for transmitting and receiving network data comprising:
- a first optical transceiver configured for sending modulated light;
- a second optical transceiver configured for receiving modulated light;
- an optical fiber coupling the first optical transceiver to the second optical transceiver;
- where the second optical transceiver is configured to perform a digital measurement of at least one signal parameter reflecting optical power levels of the received modulated light, and
- where the first optical transceiver is configured to adjust the modulated light sent by the first optical transceiver in accordance with the digital measurement.
