Abstract: A phase modulation device is provided that comprises a retardation device and a control device. The retardation device is characterized by first and second polarization eigenstates SOPf and SOPs. Light polarized according to the second polarization eigenstate SOPs acquires, upon passing through said retardation device, a delay with regard to light polarized according to the first polarization eigenstate SOPf, which delay corresponds to λ/2±30%, preferably λ/2±20% and most preferably λ/2±10%. The retardation device is arranged to receive input light having a polarization state SOPf; that defines an angle with respect to one of the first and second polarization eigenstates SOPf, SOPs within a predetermined angle range and to emit output light. The control device is configured to control at least one of a change of the angle between the polarization state SOPi; of
the input light and the respective polarization eigenstate SOPf, SOPs by less than 0.1*π, preferably less than 0.05*π and most preferably less than 0.02*π; and a change of the amount of said delay upon passing through said retardation device by less than 0.3*λ, preferably less than 0.2*λ and most preferably less than 0.1*λ, such that a phase shift of π±30%, preferably π±20% and most preferably π±10% on the output light is obtained.

Abstract: A method for determining the position of an irregularity in an optical transmission fiber using an optical time domain reflectometer, the method comprising the steps of emitting a succession of sampling light pulses into the optical transmission fiber, detecting reflected light pulses resulting from the reflection of the sampling light pulses at the irregularity in the optical transmission fiber and generating corresponding time-dependent detection signals, wherein different delays are associated with detection signals corresponding to different sampling light pulses, obtaining a combined signal from the detection signals, and analyzing the combined signal for determining the position of the irregularity in the optical transmission fiber with respect to the optical time domain reflectometer, wherein the combined signal corresponds to a super-position of the detection signals.

Abstract: Enclosed herewith is a method for protecting a link in an optical network configured for transmitting digital data employing a predetermined modulation format which comprises a number of symbols in a constellation diagram. A binary address is associated with each symbol. The modulation format allows for a constellation distortion, according to which the relative positions of constellation points in the constellation diagram are varied in a predetermined way by a predetermined degree. The method comprises the steps of: A) partitioning the traffic in two or more priority classes, B) mapping higher priority traffic to predefined bit positions within the binary symbol addresses, C) evaluating the quality of a predetermined protection link, D) determining a degree of distortion such that a desired transmission quality for the transmission of the traffic of the highest priority class or classes via said predetermined protection link and a desired transmission quality for the full traffic via said given link are simultaneously ensured, and E) employing said distorted constellation diagram for transmission of digital data over said given link.
