Effect of Bending Optical Fibre on Bend Loss over a Long Period of Time
نویسندگان
چکیده
In Malaysia, fiber cable is commonly installed underground or overhead. Once optical fibre cable is installed either underground or over-head, there is no physical maintenance implemented. The only maintenance on fibre cable is the monitoring of optical fibre attenuation. Bend loss affects the attenuation and any bending cable that contributes to the bend loss remains unmaintained since there is no study on the effect of bending fibre on bend loss in a long period of time. The effect of bending optical fibre in long term is investigated in this paper. The study has been done on the existing optical fibre of OPGW that is installed on a high voltage transmission tower. The effect of bending optical fibre with bend loss is monitored in 10 months and the permanency is verified.

Birefringence analysis of multilayer leaky cladding optical fibre
We analyze a multilayer leaky cladding (MLC) fibre using the finite element method and study the effect of the MLC on the bending loss and birefringence of two types of structures: i) a circular-core large-mode area structure and ii) an elliptical-small-core structure. In a large-mode-area structure, we verify that the multi-layer leaky cladding strongly discriminates against higher order modes...
متن کاملEffect of Nonlinear Phase Variation in Optical Millimetre Wave Radio over Fibre Systems
In this paper, we propose an optical millimetre wave radio-over-fibre (mm-wave RoF) system that uses a dual drive Mach Zehnder modulator (DD-MZM), which is biased at the maximum transmission biasing point, to generate an optical double sideband-suppressed carrier. The input to the DD-MZM are binary phase shift keying (BPSK), quadrature phase shift keying (QPSK), 8-phase shift keying (8-PSK) and...
متن کاملOptical fibre long-period grating sensors: characteristics and application
Recent research on fibre optic long-period gratings (LPGs) is reviewed with emphasis placed upon the characteristics of LPGs that make them attractive for applications in sensing strain, temperature, bend radius and external index of refraction. The prospect of the development of multi-parameter sensors, capable of simultaneously monitoring a number of these measurands will be discussed.
متن کاملTemperature insensitive long period grating sensors in photonic crystal fibre
A Long Period Grating was fabricated in endlessly single mode photonic crystal fibre using a spatially-periodic electric arc discharge. The sensing characteristics of the grating were studied and it was found to possess an insensitivity to temperature, a bend sensitivity of 3.7 nm.m and a strain sensitivity of -2.0 pm/με. Introduction: Long period gratings (LPGs) consist of a large scale (hundr...
متن کاملRaman Spectra of a PMMA Microstructured Optical Fibre and Direct Measurement of Its Gain Coefficient
A polymethylmethacrylate (PMMA) microstructured polymer optical fiber (mPOF) is fabricated and characterized. Using the cut-back technique the fiber loss is measured which is higher than the step-index silica fibers. Through a novel experimental scheme, the backward Stokes spectrum of the fabricated mPOF is recorded over a range exceeding 3000 cm‑1 during the cut-back method and compared ...
