  ABSTRACT: We experimentally demonstrate a 42.6 Gbit/s asynchronous digital optical regenerator (ADORE) in a dual-window quad-gate configuration using an EAM loop and a dual-gate configuration using a single MZM. These ADORE configurations regenerate, re-shape, and re-time incoming asynchronous bursts of data to a local clock with a desired wavelength without the need for any clock recovery. The dual-window quad-gate and dual-gate ADOREs were used to regenerate and retime a 42.6 Gbit/s RZ-ASK data signal to a local generated clock with a maximum receiver penalty of only ~4.5 dB and ~2 dB, respectively, for any arbitrary data input phase delay.

  ABSTRACT: This paper proposes an innovative self-managed optical network architecture for heterogenous transparent optical networks. A self-optimized dynamic network testbed that comprises multiple multi bit-rate ligthpaths on a mesh topology that utilizes a dark fiber link has been implemented and evaluated.

  ABSTRACT: An enhanced version of hardware accelerated QoT estimation tool in impairment-aware optical network is demonstrated and evaluated against the different number of lightpaths and wavelengths per link. It outperforms the software version by 28 times in the order of millisecond. Postprint (published version)
