Dynamic bandwidth allocation in time division multiplexed passive optical networks: a dual-standard analysis of ITU-T and IEEE standard algorithms [PDF]

PeerJ Computer Science
In the last 25 years, operators have effectively established passive optical networks (PONs), catering to around 1 billion users and earning income surpassing 8.5 billion Euros. Major standardization bodies like IEEE and ITU-T have introduced several PON

Investigation of a Flexible Downstream Scheme for Sampling Rate and Bandwidth Reduction in Short Reach Communication Systems

IEEE Access, 2020
We demonstrate a cost- and spectrum-effective orthogonal frequency-division multiple access passive optical network downstream scheme based on multi-band and modified sub-Nyquist sampling over transmission reach of 20km.

Performances of Conventional SOAs Versus QD-SOA in 1530-nm Upstream Transmission of 40 Gb/s Access Network

IEEE Photonics Journal, 2022
SOA is the key device for burst-mode upstream transmission of 40 Gb/s access network to extend distance and increase users. We evaluate two conventional SOAs and our QD-SOA in networks, consisting of 20-km Single Mode Fiber (SMF) and splitters (1 ...

UDWDM-PON using low-cost coherent transceivers with limited tunability and heuristic DWA [PDF]

, 2016
A new Passive Optical Network (PON) for access, making use of Ultra Dense Wavelength Division Multiplexing (UDWDM) by densely spacing channels at few GHz, and introducing the “wavelength-to-the-user” concept, is proposed.
