Performance evaluation of single carrier 40-Gbit/s downstream for long-reach passive optical network [PDF]
, 2014 This paper presents a new long reach PON (LR-PON) scenario operating at a single carrier of 40-Gbit/s for downstream, as an upgrade option of the LR-PON evolutionary strategy. An electrical 3-level duobinary modulation format was proposed for the 40-Gbit/

Performance Analysis of Microwave Photonic Spectral Filters based on Optical Microcombs
Advanced Physics Research, Volume 4, Issue 1, January 2025.A comprehensive analysis of microcomb‐based microwave spectral filters based on the transversal filter approach is presented. Theoretical limitations in the filter spectral response from finite tap numbers, experimental errors, and the influence of the input signal's bandwidth are all analyzed.

Distributed remote antenna unit with selection‐based of (RoF‐IoT) paradigm: Performance improvement
IET Communications, Volume 19, Issue 1, January/December 2025.Abstract Mixing the wireless medium with fiber optics can form a new communication system called a radio‐over‐fiber (RoF) network; it is a promising solution that can provide high bandwidth and a reliable connection between numerous sensors in wireless sensor networks (WSN) and the central office (base station) within a particular area.

Optical signal to noise ratio monitoring using single channel sampling technique.
Optics Express, 2014 In this paper, we propose a novel method to depict 2-dimension (2-D) phase portrait by using single-channel-sampling (SCS) technique, which can be used for optical performance monitoring.
