High quality soliton loss-compensation in 38 km dispersion-decreasing fibre

Straight line 10 Gb/s soliton transmission over 1000 km of standard fibre with in-line chirped fibre grating for partial dispersion compensation

We demonstrate a highly practical and robust soliton transmission system with partial dispersion compensation. Error free transmission was obtained for 10 Gb/s &ta over 1000 km of standard fibre with nominal dispersion of 17 ps/nrm km. Despite variations in the dispersion compensation ratio and the relatively high UV-induced birefiingence of the fibre gratings the system exhibits BERs below lo”...

Second zero dispersion wavelength measurement through soliton self-frequency shift compensation in suspended core fibre

We describe a simple experimental technique to evaluate the second zero dispersion wavelength of very small core microstrutured fibres. Based on the effect of soliton selffrequency shift and its subsequent compensation in the vicinity of the second zero dispersion, the proposed method is applied to both standard and suspended core microstructured fibres by simply measuring the frequency stabili...

High-speed fibre Bragg grating sensor interrogation using dispersion- compensation fibre

Introduction: Fibre Bragg gratings (FBGs) have proved themselves as the ideal candidates for measuring strain and temperature in smart structures, civil engineering or other harsh environments. The advantages of the FBG sensor over conventional electrical sensors include small size, light weight, immunity to electromagnetic interference, low cost and other inherent advantages of fibre-optic sen...

Advanced Fibre Bragg Gratings for High Performance Dispersion Compensation in DWDM Systems

Polarization Mode Dispersion compensation in WDM system using dispersion compensating fibre

In this paper, the polarization mode dispersion in eight channel WDM system is evaluated by considering one even channel and one odd channel performance parameters like BER and Q-factor. As PMD effects transmission at high bit rates so it is compensated with the help of dispersion compensating fibre at different distances by controlling the polarising angle with the help of polarization control...
