Recently it has been demonstrated that pulse width modulation (PWM) can represent a viable solution for the analog optical fronthaul alternative to standard radio over fibre, which still avoids the bandwidth expansion of the digital fronthaul. The PWM encodes the analog samples at the transmitter onto the duration of the on/off keyed optical signal, splitting the sampling and quantization of the radio...

WDM-PON colourless transmitters based on RSOA self-seeding (SS) proved to be compact self-tuning transceivers up to 10 Gb/s. We employ frequency-division multiplexing (FDM) with different subcarrier modulations to effectively exploit a 2-GHz limited O-band RSOA in a SS architecture, achieving, for the first time to the best of our knowledge, 12-Gb/s transmission over 10-km SSMF. Due to O-band low...
WDM PONs offering point-to-point connectivity, independence of multiple access protocol to share the medium are good candidates for supporting the new fronthaul fibre network requirements. The necessity to allow inventory and maintenance cost reduction will favour WDM PON solutions based on colourless transceivers. We present the proposal of a network embedded self-tuning colourless transmitter, based...
We present an experimental analysis on externally seeded colourless transmitters for WDM PON. We take advantage of direct modulation of a high performance MQW RSOA. Chirp is analysed as main limiting factor to SSMF propagation at 10 Gb/s. We demonstrate that off-set filtering performed by the OLT demultiplexer allows to cope with chromatic dispersion impairments and to bridge 24-km SSMF at 10 Gb/s...
