OPTISCHES MODUL ZUR KOMPENSATION DER CHROMATISCHEN DISPERSION UND ENTSPRECHENDES VERFAHREN

摘要

The module has a portion of fiber (10) with a variable pitch Bragg grating. The fiber portion attached to flexible mountings (2, 2`) at two rigid mount points (4, 4`). A mechanical piezoelectric actuator (20) acts on a mechanical structure (1) to compress a section and stretch another section of the Bragg grating portion of fiber, while keeping a central section of the grating portion of the fiber fixed. - Independent claims are also included for the following: - (A) a system of optical transmission through wavelength multiplexing - (B) a chromatic dispersion compensation process.
