Line Coding for Downlink DML Modulation in λ λ-Shared, RSOA-based Asymmetric Bidirectional WDM PONs
Line Coding Downlink DML Modulation λ λ-Shared RSOA-based Asymmetric Bidirectional WDM PONs
2015/5/20
We experimentally investigate the use of various DC-balanced line codes for downlink modulation in single-fiber, wavelength-shared WDM-PON systems which employ 10-Gbps directly modulated lasers and 2....
Self-seeding of R-SOAs is a polarization dependent process resulting in unstable operations. We experimentally demonstrate a passive stabilization technique enabling class carrier availability in 1.25...
An ASE-Injected FP-LD-Based Return-to-Zero Transmitter for Long-Reach WDM-PONs
Fiber optics optical communications Fiber optics communications
2015/6/10
We propose and demonstrate a simple RZ transmitter based on incoherent-light-injected FP-LD which improves the dispersion tolerance by a factor of 1.5. Thanks to wide timing margin between adjacent bi...

Colourless real-time 16-QAM optical OFDM end-to-end transmission at 7.5Gb/s over 25km SSMF is demonstrated experimentally, for the first time, using variable power loading and live-optimised RSOA inte...
Optimization and Comparison of the Transmission Performance of RSOA/SOA Intensity-Modulated Optical OFDM Signals for WDM-PONs
Fiber optics communications Modulation Semiconductor optical amplifiers
2015/6/4
For optical OFDM IMDD systems, optimum operating conditions of RSOA/SOA intensity modulators are identified, under which similar performances are obtained for different modulators. Under low-cost comp...
