Title:
OPTICAL FIBER TRANSMISSION SYSTEMS WITH SUPPRESSED LIGHT SCATTERING
Document Type and Number:
WIPO Patent Application WO2002069529
Kind Code:
A3
Abstract:
A system and method for suppressing light scattering in optical fiber transmission systems are disclosed. The system (600) includes an optical fiber assembly (620) having first and second ends and at least one blocking apparatus (610) disposed along the fiber between the first and second ends. The method includes providing a fiber assembly having a first end and a second end; installing a blocking apparatus in the fiber assembly between the first end and the second end; and transmitting light between the first end and the second end. The fiber assembly generates Brillouin and Rayleigh scattering light in a direction opposite the direction of the transmitted light, and the blocking apparatus suppresses the Brillouin and Rayleigh scattering light. A method of optimizing the location of a blocking apparatus is also disclosed.
