Timing jitter analysis of a multi-wavelength all-optical regenerator

We designed and built a novel all-optical re-timing, re-amplifying, and re-shaping (3R) regeneration system based on terahertz optical asymmetric demultiplexers (TOADs) developed in our laboratory. The system is capable of parallel processing multiple wavelengths, a feature which will significantly improve the scalability of current wavelength division multiplexing (WDM) networks. Performance against timing jitter of the regenerator is analyzed by VPI TransmissionMakertrade simulation platform and supported with experimental results at 10 Gb/s bit rate. The all-optical regenerator showed jitter tolerance up to 0.8 UIpp, while breaking the original input BER floor with improved BER at 10-9.
