Design and Implementation of ROADM Based on Fiber Bragg Grating and Optical Switch

摘要

With the development of optical communication technology, all-optical network is promising in next generation networks. Characterized by good transparency, wavelength routing, compatibility and scalability, all-optical network has become the most promising candidate for future high-capacity network. And reconfigurable optical add/drop multiplexer (ROADM) has been regarded as one of the key equipments of the intelligent WDM optical communication network. In this paper, we compare several design methods of ROADM, and introduce the design and implementation of ROADM based on fiber Bragg grating (FBG) and optical switch (OSW). We also propose the new idea of FBGs OSW composed OSW and FBG collimator, which is the integration package of FBGs and collimator. Benefited from the filter characteristics of FBGs and the selectivity of OSW, the performance of ROADM can be optimized. In addition, the ROADM has been tested and analyzed.
