Cost-Effective Multi-Services Hybrid Access Networks with no Optical Filter at Remote Nodes
2011/11/22
This letter experimentally demonstrates a multiservices hybrid access network integrated radio-over-fiber and fiber-to-the-home systems which share the same distributed architecture. A 1.25-Gb/s baseb...
A Cost-effective Pilot-Tone-based Monitoring Technique for Power Saving in RSOA-based WDM-PON
Cost-effective Pilot-Tone-based Monitoring Technique Power Saving RSOA-based WDM-PON
2015/5/21
We propose and experimentally demonstrate a simple and novel monitoring technique with the modulation of RSOA’s ASE by the pilot-tone monitoring signal at the ONU, to provide power saving in RSOA-base...

Employing rectangular TO-CAN and optimizing coupling mode of transmission line realize both TEC power consumption of 0.6W at 90 °C and superior optical output waveform with mask margin of 24% at 10.7...
Cost Efficient Directly Modulated DPSK Downstream Transmitter and Colourless Upstream Remodulation for Full-duplex WDM-PONs
Optical communications Phase modulation
2015/6/4
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.
Low Cost Multi-Impairment Monitoring Technique for 43 Gbps DPSK and 86 Gbps DP-DPSK Using Delay Tap Asynchronous Sampling Method
Multi-Impairment Monitoring Technique DPSK DP-DPSK
2015/7/17
We present a novel low cost method of multi-impairment monitoring for 43 Gbps DPSK using delay tap asynchronous sampling with 12 GHz receivers. This technique is also demonstrated for 86 Gbps DP-DPSK ...

Error-free transmission over 20km of 8-channels for both downstream and upstream in colourless WDM-PON based on injection-locked Fabry-Perot laser is experimentally demonstrated at 2.5Gbit/s, using a ...
Reducing the Optical Component Cost for Future Fibre Access
Optical Component Cost Future Fibre Access
2015/7/15
Next generation fibre access will require components with performance comparable to today’s long-haul DWDM but at GPON prices. This paper outlines the role of “colourless” technology and photonic inte...
