  • Channel validation in optical networks using multi-channel impairment evaluation
    Patent number: 9749042
    Abstract: In an optical communication network that includes a plurality of interconnected network nodes, a method includes storing in each network node, and for each communication channel that traverses the node, one or more impairment margins of respective impairments that affect the communication channel. A potential communication channel that traverses a subset of the nodes in the network is identified. A quality of the potential communication channel is evaluated by processing the impairment margins stored in the nodes in the subset.
    Type: Grant
    Filed: July 22, 2014
    Date of Patent: August 29, 2017
    Assignee: Cisco Technology, Inc
    Inventors: Rosanna Pastorelli, Stefano Piciaccia, Alberto Tanzi, Eliana Silvia Vercelli

  • Channel validation in optical networks using multi-channel impairment evaluation
    Patent number: 8670666
    Abstract: In an optical communication network that includes a plurality of interconnected network nodes, a method includes storing in each network node one or more cross-talk margins of respective communication channels that traverse the node. A potential communication channel that traverses a subset of the nodes in the network is identified. A quality of the potential communication channel is evaluated by processing the cross-talk margins stored in the nodes in the subset.

  • Modular Raman pump double-multiplexer
    Patent number: 6731425
    Abstract: Optical amplification bandwidth is improved by providing an economical and practical way of multiplexing together multiple Raman pump energy sources at disparate wavelengths. An arrayed waveguide grating (AWG) may be used to implement a double multiplexer. The insertion loss of the AWG is very low, allowing a reduction in the necessary power. Also, a single AWG may be used to combine numerous pump wavelengths.
