Title:
ALL-OPTICAL REGENERATOR SELF-ADAPTING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2019/033331
Kind Code:
A1
Abstract:
Disclosed is an all-optical regenerator self-adapting apparatus, consisting of a bandwidth adjustable filter unit (1), an automatic gain control (AGC) light amplification unit (2), a signal processing/control unit (3) and a light shaping unit (4). Under the control of the signal processing/control unit (3), measurement of the optical power of an input degraded signal is automatically completed by means of the bandwidth adjustable filter unit (1), and the operating bandwidth of a bandwidth adjustable filter (101) is fixed in an optimized position. The signal processing/control unit (3) determines, by means of an externally input clock pumping power detected by a photoelectric detector (303) inside the signal processing/control unit, an optimal operating point of a light shaper, and thus controls, according to the characteristics of an input degraded signal, an amplification factor of an AGC gain light amplifier, so that an all-optical regenerator always operates in an optimal state matching an input signal.
