Abstract
In this paper, we theoretically and experimentally introduce a new reconfigurable optical add/drop multiplexers (ROADM) module which bases on the narrow-band optical switch (NBOS) technology and achieves the narrow-band optical switching with a Fabry-Perot cavity. In comparison with the analysis of the current ROADM technologies, the NBOS-based ROADM module is proven to be cost-effective, low insertion loss, narrow-band, and has a more mature technology. It would grow to be a cost-effective ROADM solution than any of the others.
