Optical network unit (ONU)'s wavelength tuning time is a key factor that cannot be ignored in
ONU scheduling algorithm for multi-wavelengths passive optical network (PON). In this …

With the smooth upgrade of the access network, multiple tuning-time devices will coexist in
the long-reach access network, and the subsequent problems of high round-trip time (RTT) …

Abstract Hybrid WDM–TDM PON (wavelength division multiplexing–time division
multiplexing passive optical network) that applies wavelength-independent or colorless …

Abstract Long Reach PONs (LR-PON) were proposed to extend the benefits of Passive
Optical Networks (PON) to more users and to a larger area. This paper considers a Dynamic …

The unused slot remainder (USR) problem in Ethernet Passive Optical Networks and long-
reach Passive Optical Networks (LR-PONs) results in both a lower bandwidth utilization and …

To achieve low-latency and energy-efficient in a 10 Gbps Ethernet Passive Optical Network
(10G-EPON) having heterogeneous Optical Network Unit (ONU) propagation delays, this …

In this paper, we present a new service scheme, Periodic GATE Optimization (PGO) for long-
reach passive optical networks. PGO is based on a previously proposed service scheme …

An inter multi-thread polling algorithm (IMTP) applied for the bandwidth allocation in Long-
Reach passive optical network (LR-PON) is proposed. Simulation results show that IMTP …

Passive optical network (PON) is a highly dynamic access network that effectively converges
several service providers. In a time cycle, some optical network units (ONUs) of a PON may …

Presented is a fuzzy-logic-based scheduling algorithm for passive optical networks (PONs)
that considers four different metrics to allocate an upstream bandwidth to optical network …
