  • Method and apparatus for monitoring mechanical fiber stress of optical fiber spans
    Patent number: 9337921
    Abstract: The length of the optical fiber section under tension expands by a certain amount that is proportional to the level of tension applied to it. Monitoring the variations in the phase of the arriving signal allows to discover a fiber that is subject to a certain level of mechanical tension. With the method and apparatus according to the present invention it is possible to protect optical communication channels against failures in an optical transmission fiber that are caused by any kind of mechanical disturbances.
    Type: Grant
    Filed: November 14, 2013
    Date of Patent: May 10, 2016
    Assignee: ADVA Optical Networking SE
    Inventors: Mohammad Alfiad, Mark Filer, Ted Rabenko, Sorin Tibuleac

  • Method of operating an optical transmission system and optical transmission system
    Patent number: 8818195
    Abstract: The invention relates to a method of operating an optical transmission system (100), wherein an optical signal (s, s1) is transmitted (200) through at least one component (102) of said optical transmission system (100) which exhibits spectral phase ripple, and wherein a phase of at least one frequency component of said optical signal (s, s1) is altered (210) by phase influencing means (110) to at least partly compensate for said phase ripple of said at least one component (102), whereby a phase ripple compensated signal (s2) is obtained.
