Symmetric 10G-EPON ONU burst-mode transceiver employing dynamic power save control circuit was, for the first time, developed. Reduction of power consumption up to 37.7% was successfully achieved with...
In a cost-effective TDM-OCDMA-PON system without en/decoder at each ONU, the uplink dispersion-compensation-free 10 Gbps/1 Gbps-co-existing TDM x 4-OCDMA transmission over 100 km SMF is demonstrated b...
Chirped IRZ downstream is used together with a delay interferometer and a RSOA at a low complexity ONU for full-duplex 10.5Gbps transmission on a single wavelength, supported by modulation format conv...
We propose an SLA-based scheduling scheme for EPON in which OLT can adjust sleep time and ONU can quit sleep mode for sending expedited frames. Considerable energy can be saved under practical power c...
We propose and demonstrate an OCDMA-PON scheme with optical network unit (ONU) internetworking capability, which utilizes low-cost gain-switched Fabry-Pérot (GS-FP) lasers with external dual-wavelengt...
A n energy conserving TDM-PON architecture using sleep mode ONU is presented. Sleep mode ONU with fast wake-up capability is demonstrated. The architecture employs novel just-in-time sleep control sch...
A single-fiber full-duplex hybrid TDM/WDM-PON is demonstrated to operate at 2.5/1.25 Gbps rates, with RSOA ONU. It achieves high power budget (GPON compliant) at a distances higher than 20km, and serv...
We developed symmetric 10G-EPON ONU transceiver fully compliant with IEEE802.3av PR30.Output power of +5dBm, sensitivity of -32.4dBm, and fast LD turn-on/off time of 10ns/7ns were successfully achieve...
We demonstrated 10Gb/s bi-directional symmetric transmission based on polarization-division multiplexing with a centralized light source. One of two orthogonal polarization states carries downstream d...
The influence of the distribution element position in PONs is reported. Best Crosstalk-to-Signal ratio (C/S) is achieved if it is placed either in the ONU or OLT vicinity with optimum ONU gain dependi...
We present a new approach to mitigate the gain transients in remote Erbium Doped Fibre Amplifiers by means of pre-distortion of data packets at the ONU, allowing a strong reduction (30%) of the packet...
This paper presents the first burst-mode system tests of a new hybrid 10Gb/s DWDM-TDM PON. The upstream channels in the network are enabled by combining novel, cost-effective tuneable ONU lasers and a...
The optimum design characteristics to maximize the performance of 10Gbps full-duplex bidirectional transmission are studied experimentally using a low-bandwidth RSOA assisted by electronic equalizatio...
We present experiments on a wavelength-flexible WDM/TDM-PON with an integrated reconfigurable OADM and a reflective electro-absorption modulator. We successfully transmit multiple wavelength channels ...
We demonstrate a full-duplex DPSK SCM PON operating at 2.5Gbps/1.25Gbps bitrates, with RSOA ONU and simplified scheme. It achieves low sensitivity and is implemented with low-cost components.
