Improvement of all optical networks with Bragg grating fibers

In this paper we mainly discuss the low-cost way to improve the performances of wavelength routed optical networks. It is really a tough work to reduce the probability of traffic loss due to the lack of abundant lightpath between arbitrary nodes connected by precious wavelengths. Aiming to solve the problem, we probe an economical proposal that local optical nodes can be equipped with extra receiving components with cheap Chirp Bragg Gratings. Under the experimental platform of single-direction double-fibers optical network rings, this scheme has been verified, showing the result that the traffic loss ratio can be reduced significantly by adding more Chirp Bragg Gratings especially under heavy service loads. Consequently, it is feasible to improve the performance of all optical networks with several groups of Chirp Bragg grating fibers with whole consideration of cost-effective optical network design.
