  • Method for localizing an optical network termination in an optical access network
    Patent number: 8755689
    Abstract: A method for localizing an optical network termination in an optical access network including an optical line termination and a number of optical links.
    Type: Grant
    Filed: May 29, 2008
    Date of Patent: June 17, 2014
    Assignee: Telecom Italia S.p.A.
    Inventors: Maurizio Valvo, Roberto Mercinelli, Paolo Solina
  • Method for increasing security in a passive optical network
    Patent number: 8490159
    Abstract: A method for security in a passive optical network is disclosed. The method includes, at an optical line termination (OLT): detecting an optical termination device and establishing a connection with the device; generating a first authentication message including a first random number; and transmitting the first authentication message through the established connection. At the optical termination device, the method may include: receiving the first authentication message; calculating a first authentication code by using the first random number and a secret code stored at the device; and generating and transmitting to the OLT a second authentication message including the first authentication code.

  • Method of and device for controlling the peak power of a laser transmitter in discontinuous optical transmission systems
    Patent number: 5530712
    Abstract: A method and apparatus is disclosed for modulating a laser by a current resulting from the combination fo a threshold current and a current due to a data signal and in which a fraction of the laser output signal is taken and converted into a monitoring current, such monitoring current is sampled, an actual value of the peak power is obtained as an average over a number of samples of the monitoring current, the actual value of the peak power thus found is compared with a desired value of the peak power and an updated value for the laser threshold current is obtained from the difference, if any, between the desired value and the actual value, the updated value being such as to compensate for the difference.
