Abstract (en)
[origin: WO9935775A1] The present invention provides an expandable and cost-effective high capacity optical communication system using wavelength-division-multiplexing. Low-loss modular multiplexers and demultiplexers are used to increase the flexibility of the system and reduce overall system insertion loss.
