Field Transmission using Fiber Bragg Grating-based Dispersion Compensating Modules with Continuous Response over the Full C-band
Fiber Bragg grating-based dispersion compensating modules with continuous response over the full C-band are demonstrated. Group delay characteristics are analysed and modules are used in 10-Gbit/s and 40-Gbit/s field experiments over 820 km installed fiber.
16 x 10 Gb/s WDM transmission over 840-km SMF using eleven broad-band chirped fiber gratings
We demonstrate wavelength-division-multiplexed transmission of 16 10-Gb/s nonreturn-to-zero channels with 50-GHz spacing over 840 km of conventional single-mode fiber (SMF), or 14 times the 10-Gb/s dispersion limit, using a total of eleven chirped fiber gratings for dispersion compensation. Each grating has a nominal dispersion of -1330 ps/nm km for compensating 80 km of SMF and a bandwidth of 6.5 nm, and one grating has additional dispersion slope compensation of -35 ps/nm/sup 2/ equivalent to 480 km of SMF. The large number of closely spaced wavelengths and long transmission distance significantly stress the wavelength uniformity, bandwidth, and cascadability of the fiber gratings.
Chirped fiber grating characterization with phase ripples
The performance of chirped fiber gratings as dispersion compensators can be specified with the variance of their phase ripples weighted by the input signal spectrum.
