We propose a novel noise-suppression scheme in spectrum-sliced WDM-PONs.Experimentally, low-noise windows can be created in which the noise is reduced by more than 20dB and the performance of vector s...
WDM-PONs for 10-Gb/s bidirectional transmission are realized with REAMs as ONUs and ASE source for channel fault monitoring. The remotely pumped scheme can simultaneously boost up- and down-stream sig...
Time-interleaved phase remodulation is proposed to realize broadcast transmission for WDM-PONs. Simultaneous transmission of 5-Gb/s bidirectional unicast data and broadcast data is demonstrated at the...
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...
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...
Optically assisted downstream cancellation for wavelength reuse in WDM-PONs is demonstrated, allowing downstream extinction ratios up to 9dB for symmetrical full-duplex data transmission at 10Gbps wit...
The presented “Scalable Advanced Ring-based passive Dense Access Network Architecture” transparently integrates WDM metro and PON access technologies,implementing ring protection, 100Km reach and up t...
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...
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...
We demonstrate 10Gb/s VCSEL transmission for WDM PON over 23.6km single mode fiber. Dispersion penalty is limited to 2.9dB by introducing a wavelength offset with respect to the remote array waveguide...
We implement a cost efficient 10.7Gb/s directly modulated DPSK transmitter in a bidirectional WDM-PON, which also remodulates the downstream phase encoded signal for 2.5Gb/s OOK upstream transmission.
An Optical Network Unit based on colourless detection of optical frequency modulated signals based on a combination of Semiconductor Optical Amplifier and Reflective Electroabsorption modulator with i...
The reduction of both Rayleigh backscattering and reflections in passive optical networks with remotely seeded network units by means of optical frequency dithering is demonstrated.
We propose a novel automatic wavelength control method for a tunable laser for wavelength division multiplexed-passive optical networks by using a low power broadband light source.
