Special Issue Information

Dear Colleagues,

Modern technologies developed based on optical fibre in the last few decades have achieved significant success in different research fields (e.g., communications, physics, biology, chemistry, materials, medicine, earth science, computer science, etc.), with a variety of applications in data communications, material processing, sensing, detection, monitoring, and for light computing purposes. Due to advantages such as low-cost implementation, compact size and low weight, immunity to electromagnetic interferences, chemical resistance, long distance transmission and large multiplexing capability, optical fibres are steadily being utilized in applications ranging from home broadband to aero-spacecraft sensors. Hence, optical fibre research, as a traditional and fundamental discipline, plays an important role in aspects of our daily life to national defence alike.

The aim of this Special Issue is to highlight the latest developments and trends in state-of-the-art optical fibre research (technical, numerical, and methodological) through the collection of articles covering recent improvements in, but not limited to, the following areas of interest:

  • Basic and fundamental theory of optical fibre and optical fibre-based systems in long-haul, medium-haul, and short-haul communications;
  • The design, fabrication, and application of special fibres (e.g., photonic crystal fibre (PCF), microstructured fibre);
  • Optical fibre (bio/chemical/physical) sensing devices (fibre Bragg gratings (FBG) and PCF-based surface plasmonic resonance (SPR));
  • Optical fibre devices/systems for high-speed 5G and 6G Internet communication and networks;
  • Optical fibre laser, sources, and amplifiers;
  • Nonlinear fibre optics.

Contributions from all areas of research involving optical fibre are welcome. We are pleased to invite you to participate by submitting original research papers, communications, and review articles to provide broad insight into recent developments and the future outlook in this Special Issue.

We look forward to receiving your contributions.

In this paper, we proposed and experimentally demonstrated the association of a fiber Bragg Grating (FBG) sensing system with You Only Look Once V7 (YOLO V7) to identify the vibration signal of a faulty machine. In the experiment, the YOLO V7 network architecture consists of a backbone, three detection heads (Headx3), a path aggregation network (PAN), and a feature pyramid network (FPN). The proposed architecture has an FBG sensor and the FBG interrogator employed for collecting sensing vibration signals or vibration data when degradation or fault occurs. An FBG interrogator collects vibration data independently, and then the YOLO V7 object detection algorithm is the recognition architecture of the vibration pattern of the signal. Thus, the proposed vibration recognition or detection is an assurance for detecting vibration signals that can support monitoring the machine’s health. Moreover, this research is promising for ensuring a high accuracy detection of faulty signals rate in industrial equipment monitoring and offers a robust system, resulting in remarkable accuracy with an overall model accuracy of 99.7%. The result shows that the model can identify the faulty signal more accurately and effectively detect the faulty vibration signal using the detection algorithm. Full article

In the paper, a dual-bidirectional ring-type wavelength-division-multiplexing (WDM) access network with downlink and uplink signal access simultaneously using a single fiber backbone in clockwise and counterclockwise directions, respectively. The proposed network architecture is simple and easy to implement via the designed remote node (RN) and optical line termination (OLT) modules, but it also can double the downlink traffic using the original WDM downlink wavelengths. The presented ring-type WDM network can also avoid the Rayleigh backscattering (RB) beat noise when the same wavelengths are applied as downlink and uplink channels concurrently. In the measurement, 50 km long-reach and 15 km short-reach fiber transmission lengths are achieved for the symmetrical 10 and 28 Gbit/s on-off keying (OOK) data access, respectively. In addition, based on the obtained power budgets of eight downlink WDM signals and network design at the forward error correction (FEC) threshold, 16 optical network units (ONUs) can be supported simultaneously.
