A 10-Gb/s 1024-way-split 100-km long-reach optical-access network [PDF]

open access: yesJournal of Lightwave Technology, 2007
Optical-access networks have been developed to remove the access-network bandwidth bottleneck. However, the current solutions do not adequately address the network economics to provide a truly cost-effective solution.

Planning of Optical Connections in 5G Packet-Optical xHaul Access Network

open access: yesApplied Sciences, 2022
One of the main challenges in dense 5G radio access networks (RANs) is provisioning of low-cost connectivity between a large number of antennas, located at remote sites, and a central site (hub) in which baseband processing functions are performed ...

Dynamics of Dispersive Wave Emission From Dark Solitons in Kerr Frequency Combs

open access: yesIEEE Photonics Journal, 2016
Taking advantage of an extended Lugiato–Lefever equation with third-order dispersion, we numerically show that dark cavity solitons formed in normal dispersion of microresonators are capable of emitting dispersive waves in both normal and ...

Small-Size Reconfigurable Loop Antenna for Mobile Phone Applications

open access: yesIEEE Access, 2016
A small-size reconfigurable loop antenna for mobile phone applications with a compact volume of 55 × 5 × 3 mm3 is proposed. In addition to the traditional three loop antenna modes, namely, 0.5-λ, 1-λ, and 1.5-λ modes ...

DISCUS: an end-to-end solution for ubiquitous broadband optical access [PDF]

open access: yes, 2014
Fiber to the premises has promised to increase the capacity in telecommunications access networks for well over 30 years. While it is widely recognized that optical-fiber-based access networks will be a necessity in the short- to medium-term future, its ...

Analysis of Cascaded Soliton Spectral Tunneling Effect in Segmented Fibers With Engineered Dispersion

open access: yesIEEE Photonics Journal, 2013
The cascaded soliton spectral tunneling (SST) effect is proposed and numerically investigated in multiple optical fiber segments, which work together to transfer the soliton pulse over a wide wavelength span. A triple-cladding fiber and a solid core step-

Operating penalties in single-fiber operation 10-Gb/s, 1024-way split, 110-km long-reach optical access networks [PDF]

open access: yes, 2006
We report for the first time optical signal-to-noise penalties which lead to performance degradations in single-fiber long-reach optical access networks when compared to identical dual-fiber systems.

A green open access optical distribution network with incremental deployment support [PDF]

open access: yes, 2015
This paper proposes an optical distribution network (ODN) architecture for open access networks. The proposed scheme ensures co-existence of multiple business partners (BPs) e.g., service, network equipment, and infrastructure providers at different ...

Employing Hybrid sub-Nyquist Sampling Rates to Support Heterogeneous Services of Varying Capacity in 25-Gbps DDM-OFDM-PON

open access: yesIEEE Photonics Journal, 2018
Delay-division-multiplexing (DDM) involves the use of signal preprocessing for the detection of data via sub-Nyquist analog-to-digital sampling, based on preallocated relative sampling delays among optical network users (ONUs) in an orthogonal frequency ...
