Influence of nonideal chirped fiber grating characteristics on dispersion cancellation

Performance Evaluation of A Tunable Dispersion Compensator based on Strain-Chirped Fiber Bragg Grating in a 40 Gb/s Transmission Link

“…Thus, in both cases, passbands of the FBG were wide enough for a 40 Gb/s NRZ signal transmission. Previously, it has been reported that the ripple in reflectivity spectra of the FBG based dispersion compensator should be less than 1.67 dB for <1-dB penalty in a 10 Gb/s NRZ transmission link [9]. As it can be seen in Fig.…”

“…Among them, the chirped FBG based tunable dispersion compensator is an attractive solution for the dispersion management in high-speed optical transport networks, since it can provide high dispersion, wide passband for high bit-rate applications and wide tunability [1,[6][7][8]. However, it has been reported that the ripples in amplitude and phase response of a chirped FBG could affect the transmission system's performance [9][10]. Therefore, the system's performance should be evaluated for the feasibility demonstration of FBG based tunable dispersion compensators.…”

Performance Analysis of Chromatic Dispersion Compensation of a Chirped Fiber Grating on a Differential Phase-shift-keyed Transmission

“…In DPSK transmission, most research results ever published have used DCFs rather than CFBGs, and there are few researches about the properties of dispersion compensation of CFBGs. The effects of CFBG on the optical transmission system have been researched in the several papers [4][5][6][7]. In this paper, the comparison of a CFBG used in the OOK and the DPSK systems in 40 Gbps speed was shown by simulations.…”

Advanced fibre Bragg gratings for high performance dispersion compensation in DWDM systems

“…The inverse scattering design gives (both theoretically and experimentally) extremely linear group delay over the complete reflection bandwidth. The low level of noise on the experimental group delay (±10 ps peak to peak) has a very short spectral period (~10 pm compared to typical pulse widths of 100 -200 pm) and, from recent results [5], should not have a significant effect on the transmission of 10 Gb/s signals. The peak-to-peak group delay noise of the experimental grating is less than the theoretical deviation of the traditional apodised CFBG with the same bandwidth.…”
