AbstractData transmission using optical fiber can be affected by nonlinear effects, dispersion, and crosstalk. These effects are causing the optical signal to be degraded. Optical clock and data recovery are necessary to synchronize and regenerate the affected signal and consequently achieving a good BER value. In this paper, a system with optical clock and data recovery function using FBG and FP-FBG filter technique is tested and analyzed using OptiSystem software. Eye diagram for both configurations is observed. Some parameters are also being manipulated such as the data rate and transmission distance to compare both FBG filtering effect. Clock data recovery signal with FBG filtering shows better performance compare to FP-FBG filtering at 10 Gbps.
