Gbit / s asynchronous digital optical regenerator
We present the first experimental demonstration of an asynchronous digital optical regenerator at 42.67 Gbit/s. The system effectively retimes incoming asynchronous data bursts to a local clock without burst mode clock recovery and converts the signal to a desired wavelength and duty cycle. ©2008 Optical Society of America OCIS codes: (060.2330) Fiber optics communications; (060.4510) Optical c...
متن کاملAsynchronous Digital Optical Regenerator for 4 x 40 Gbit/s WDM to 160 Gbit/s OTDM Conversion.
We propose and numerically analyse an asynchronous digital optical regenerator using a single-EAM loop and a novel neighbor-combine approach. It effectively re-synchronizes input signals with arbitrary phases to the local clock, and regenerates signals with high amplitude fluctuation and polarization mode dispersion. We demonstrate the application of this regenerator for 4x40 Gbit/s WDM to 160 ...
متن کاملOptical LDPC decoders for beyond 100 Gbits/s optical transmission.
We present an optical low-density parity-check (LDPC) decoder suitable for implementation above 100 Gbits/s, which provides large coding gains when based on large-girth LDPC codes. We show that a basic building block, the probabilities multiplier circuit, can be implemented using a Mach-Zehnder interferometer, and we propose corresponding probabilistic-domain sum-product algorithm (SPA). We per...
متن کاملRegenerator Location Problem in Flexible Optical Networks
In this study we introduce the regenerator location problem in flexible optical networks (RLP-FON). With a given traffic demand, RLP-FON tries to solve the regenerator placement, routing, bandwidth allocation and modulation selection problems jointly to satisfy data transfer demands with the minimum number of regenerators. We propose a novel branch and price algorithm for this challenging probl...
متن کاملNumerical study of an optical regenerator exploiting self-phase modulation and spectral offset filtering at 40 Gbit/s
In this work, we numerically investigate the performances of optical regenerators based on self-phase modulation and spectral offset filtering at 40 Gbit/s. We outline the different effects affecting the device performances and explain the choice of the optimal working power. The impact of the regenerator on the output signal is also analysed through a statistical approach. Both single and doub...
