NEC America has expanded its SpectralWave family of reconfigurable optical add/drop multiplexer (ROADM) technologies with the addition of application-agile, multi-reach systems for service provider and Multiple System Operators’ (MSO) metro, regional and long distance networks. The new the 4200-series is configured to address carriers’ requirements for fiber type, reach and performance requirements.
The new 4240 Metro Edge ROADM can transport up to 40 L-band or C-band wavelengths. Key features include full add/drop at any node, full-band tunable transponders, SONET-on-a-blade multiplexers and upgrade capability to wavelength crossconnect. Topologies include optical rings, point-to-point, or linear-chain.
NEC predicts the 4200-ROADM series can play a major role in facilitating operational improvements by offering application flexibility, while cost-effectively supporting capacity requirements.
