Fujitsu Network Communications (Richardson, TX) plans to expand into the long-haul transmission arena with a variety of new products. The 32-channel Flashwave 320G OC-192 system represents the first of these new offerings. Future systems include optical add/drop multiplexers and crossconnects (which should be ready for the market next year) and the Flashwave Metro multiplexer for the metropolitan area market. Key enabling technologies for the Flashwave product line include an amplifier that incorporates a patented Faraday rotator-based variable attenuator, as well as a patented acousto-optical tunable filter that will augment the add/drop multiplexer.
