We propose a channel-reuse, long-reach WDM-PON scheme and an optical beat noise-based automatic wavelength management method. A 40 km reach, channel-reuse, 40 Gb/s/λ downstream and 10 Gb/s/λ upstream signal transmission on a 100 GHz WDM grid is demonstrated.
We propose a remotely pumped EDFA and tunable transmitter-based 40-Gb/s/λ downstream and 10-Gb/s/λ upstream transmissions long-reach WDM-PON scheme and an optical beat noise-based novel automatic wavelength control method for tunable transmitter. Transmissions of 40-Gb/s DQPSK downstream using MZ Modulator and 10-Gb/s OOK upstream using optical beat noise-based self wavelength managed tunable transmitter...
As one of the most promising next generation optical access network (OAN), flexible time and wavelength division multiplexing (TWDM) OAN can increase capacity smoothly and reallocate wavelength and timeslot resource dynamically to cope with variations in traffic pattern. However, the scheduling of both wavelength and timeslot resource becomes a critical problem. In this letter, a dynamic wavelength...
We propose a wavelength-reuse bidirectional 10-Gb/s/l long-reach WDM-PON scheme and a novel automatic wavelength control method for tunable laser-based colorless ONU. Transmissions of wavelength-reuse bidirectional 10-Gb/s OOK are demonstrated with 60-km fiber transmission and 50-GHz channel spacing.
We propose a bidirectional 40-Gb/s/X long-reach WDM-PON scheme and a novel automatic wavelength control method for tunable laser-based colorless ONU. Transmissions of 40-Gb/s DQPSK downstream and upstream are demonstrated with 40-km fiber transmission.
A novel ring-tree TWDM optical access network architecture using matrix optical switch and OEO wavelength converter is proposed. The architecture owns flexible on-demand wavelength and timeslot provision, OLT energy saving ability and backward compatibility.
In this paper, the requirements for next generation passive optical network (NG-PON) and evolution trends of PON are analyzed. Based on the analysis of the requirements for NGPON and the characteristics of various potential NG-PON schemes, it is believed that hybrid TDM/WDM PON will be the most promising candidate NG-PON schemes for different application scenes in the near future, and the OFDM PON...
Proposed in this paper is a 10-Gbps uplink transmission over 25-km fiber in WDM-PON, in which band-limited RSOAs are applied to colorless ONUs and cascaded Mach-Zehnder Interferometers are used as three-tap optical equalizers in OLT.
