Influence of Fiber-Bragg Grating-Induced Group-Delay Ripple in High-Speed Transmission Systems

“…A similar investigation of a 40 Gbit/s binary DPSK system has also been experimentally conducted as a function of the GDR presented in the system [4]. In addition, successful transmission of 10 Gbit/s OOK and 43 Gbit/s 4-ary DPSK (DQPSK) with inline FBG modules over 1000 km has recently been reported [7,8]. These results show the feasibility of using FBG modules for dispersion compensation in high-speed transmission systems.…”

Performance and cost comparison of extended length WDM-PON

“…Three commonly used techniques for dispersion compensation are employed in the simulations: Dispersion Compensating Fibers (DCFs) [8], chirped Fiber Bragg Gratings (FBG) [9][10][11][12][13][14], and FEC [15]. The diagram in Figure 3 shows the simulated configuration and indicates the place where the dispersion compensation device (e.g., DCF and FBG) is located.…”

42.8-Gb/s RZ-DQPSK Transmission With FBG-Based In-Line Dispersion Compensation

“…The GDR is caused by imperfections in the gratings fabrication process. Improved fabrication processes have, however, gradually reduced the GDR of state-of-the-art slope-matched FBGs [4], such that for 10.7-Gb/s transmission FBG-based in-line dispersion compensation is an appealing alternative to DCF, up to approximately 2000 km [5]. For future link upgrades (e.g., from 10.7 to 42.8 Gb/s per wavelength-division-multiplexing (WDM) channel), the FBGinduced penalty can still be a key concern since the higher line rate increases the associated penalty [6].…”
