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

Abstract

We have evaluated the performance of strain-chirped fiber Bragg grating (FBG) based tunable dispersion compensator in a 40 Gb/s transmission link. In our proposed compensator, the value of dispersion could be changed from -353 ps/nm to -962 ps/nm by adjusting the rotation angle of the metal beam on which the FBG was mounted. In order to evaluate the effect of ripples in reflectivity and variations in passband of the FBG based dispersion compensator, transmission performance has been measured with our tunable dispersion compensator. Error-free transmission of a 40 Gb/s non-return-to-zero (NRZ) signal over conventional single-mode fiber (SMF) was achieved.

Specialty Fiber Coupler: Fabrications and Applications

“…At both output ports of the coupler, the bit error ratio (BER) performance of HAF WDM couplers were measured with/without 6 mm bending radius at the PCF. Figure 9 presents the BER curves measured at the 1310 nm port, which shows that the HAF WDM coupler has almost no power penalty caused by the 6 mm bending radius [30]. At the 1550 nm port, the same negligible power penalty was observed also.…”

PMD Effect on the Clock-based Optimum Dispersion Compensation Monitoring Technique

“…In high-speed optical transmission systems with ≥40 Gb/s per channel, it is essential to monitor and compensate for chromatic dispersion in real time [1,2]. In the linear optical transmission systems with a low signal power, a 100-% dispersion compensation gives the best signal quality.…”

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.…”
