Abstract
An optical receiver and a method of controlling the optical receiver. The method may include setting, by a controller, a dispersion value of a dispersion compensator to compensate for a dispersion of an optical signal received through an optical fiber, compensating, by the dispersion compensator, for the dispersion of the optical signal based on the set dispersion value, performing, by the controller, an error correction with respect to the optical signal of which the dispersion is compensated and verifying a number of bit errors, and resetting, by the controller, the dispersion value of the dispersion compensator based on the verified number of bit errors.

A method of controlling an optical receiver, the method comprising:
- setting, by a controller, an optical power of an optical signal which is to be amplified and output through an optical amplifier;
- amplifying, by the optical amplifier, the optical signal, which is received through an optical fiber, based on the set optical power;
- performing, by the controller, an error correction with respect to the amplified optical signal, and verifying, by the controller, a number of bit errors;
- and
- resetting, by the controller, the optical power of the optical signal, which is to be amplified and output through the optical amplifier, based on the verified number of bit errors.
An optical receiver comprising:
- an optical amplifier configured to amplify an optical signal received through an optical fiber, based on an optical power of the optical signal which is set by a controller;
- a dispersion compensator configured to compensate for a dispersion of the optical signal output from the optical amplifier, based on a dispersion value of the dispersion compensator which is set by the controller;
- and
- the controller configured to perform an error correction with respect to the optical signal output from the dispersion compensator and verify a number of bit errors,
- wherein the controller is further configured to reset the optical power of the optical signal, which is to be amplified and output through the optical amplifier, and/or the dispersion value of the dispersion compensator, based on the verified number of bit errors.
