TWDM-PON-compatible 10 Gbps Burst-mode coherent reflective ONU achieving 31 dB ODN loss using DFB lasers

open access: yes, 2014
We present a self-coherent reflective PON demonstrator, TWDM-PON compatible, running at 10 Gbps upstream bit rate per ONU using commercial DFB lasers, achieving 31 dB ODN loss at BER=10-3 over splitter-based PON in TWDM-like burst mode ...

Traffic Scheduling Strategy for Mitigating DDoS Attack in Edge Computing-enabled TWDM-PON

open access: yes, 2020
A traffic scheduling strategy based on edge coordination is proposed to mitigate DDoS attacks for edge nodes in TWDM-PON. Results reveal that our proposed algorithm effectively reduces service blocking and QoS degradation caused by ...

Experimental demonstrations of symmetirc 40-Gb/s TWDM-PON [PDF]

open access: yes2013 9th International Conference on Information, Communications & Signal Processing, 2013
We have experimentally demonstrated symmetric 40Gb/s TWDM-PON with long passive reach and high power budget. Directly-modulated lasers (DMLs) are used as both downstream and upstream lasers to reduce the system cost, and optical reshaping filter is used to manage the chirp of the DMLs for all the upstream and downstream channels, enabling long distance

TWDM-PON With Signal Remodulation and Rayleigh Noise Circumvention for NG-PON2

open access: yesIEEE Photonics Journal, 2013
We propose and demonstrate a 40-Gb/s (4 × 10 Gb/s) downstream and 10-Gb/s (4 × 2.5 Gb/s) upstream time-wavelength-division-multiplexed passive optical network (TWDM-PON) using signal remodulation. Here, a downstream differential-phase-shift-

Symmetric 100-Gb/s DSP-enhanced TWDM-PON

open access: yes, 2014
We propose a 100-Gb/s DSP-enhanced TWDM-PON architecture. The RSOA are used to enhance the sensitivity of downstream OFDM signals, while SCFDE is used for upstream transmission to reduce the complexity and cost of access network. ?
