Identification of optical fibres in a passive optical network using highly temperature insensitive filters and reflectors

IET Optoelectronics, Volume 19, Issue 1, January/December 2025.
The authors demonstrate the use of highly temperature insensitive dense wavelength division multiplexing filters combined with optical reflectors and optical time domain reflectometry to uniquely identify specific optical fibres beyond the optical splitter in an optical access passive optical network (PON). The very low wavelength shift (∼0.1 pm/°C) of

A New Prime Code for Synchronous Optical Code Division Multiple‐Access Networks

Journal of Computer Networks and Communications, Volume 2018, Issue 1, 2018., 2018
A new spreading code based on a prime code for synchronous optical code‐division multiple‐access networks that can be used in monitoring applications has been proposed. The new code is referred to as “extended grouped new modified prime code.” This new code has the ability to support more terminal devices than other prime codes. In addition, it patches

Lossless WDM PON Photonic Integrated Receivers Including SOAs [PDF]

Applied Sciences, 2019
The role of a semiconductor optical amplifier (SOA) for amplifying downstream traffic at optical network terminals (ONT) within a silicon-photonics integrated receiver in a high capacity passive optical network (PON) is investigated. The nearly traveling wave SOA effects are evaluated by considering fabrication and link loss constraints through ...
