In this letter, we propose and demonstrate a signal- remodulated wired/wireless network using reflective semiconductor optical amplifier as a colorless modulator in the optical networking unit/remote antenna unit. Dark return-to-zero and binary phase-shift-keying signals are used for the downstream wired and wireless broadcast, respectively. The downstream signal will be remodulated to produce the...
We propose a signal remodulation of DPSK downstream and OOK upstream signals using RSOA at the customer side for the hybrid WDM-TDM PONs. Error-free operation was achieved in a 20-km-reach WDM-TDM PONs without dispersion compensation.
In this paper, we propose and experimentally investigate a simple self-injection Fabry-Perot laser scheme on each optical network unit (ONU) for 10 Gbps TDM passive optical networks (PONs). Based on the proposed four piped 2.5 Gbps lasers, the 10 Gbps uplink traffic can be easily achieved at a cost-effective way. The network architecture and performance have also been analyzed and discussed.
We present a performance analysis of a Rayleigh-noise-mitigation scheme for carrier-distributed PON, named PM-NRZ, at different AWG offsets and profiles; and at different channel separations, showing different tradeoffs in achieving DWDM operation.
