  • Technique for monitoring optical networks
    Patent number: 8837935
    Abstract: A technique for monitoring at least a network portion of an optical communication network, by monitoring changes of a decision threshold used for discriminating a digital optical signal being propagated via the network portion.
    Type: Grant

  • Method and system for span optical power control
    Patent number: 7046429
    Abstract: There is proposed a method and a module for real time control of power per optical channel in a multi-channel optical communication line formed by a group of optical elements connected in a chain by fiber spans. The group of elements comprises one or more optical fiber amplifiers (OFA); each of the spans is characterized by its span loss, while each of the OFA is characterized by its gain and its designed output power per channel. The method comprises steps of calculating an expected total input power value (EIP) for a particular optical amplifier (OFA) in the line, measuring a real total input power (MIP) at the particular optical amplifier, and comparing the values. If a difference between the EIP and the MIP at the OFA exceeds a predetermined value, the method (and the module) ensures adjusting the gain of the OFA to maintain its output power per channel constant.
