  • Manufacturing method of a device for attenuating a signal carried by an optical fiber, attenuation device, attenuation system and corresponding applications
    Publication number: 20020114606
    Abstract: An attenuation device for a signal carried by an optical fiber in the form of a light signal is manufactured. The optical cores of a first and a second single-mode fiber are expanded. The first and second fibers are assembled facing each other in a capillary containing a liquid crystal. The liquid crystal is polymerized to produce an attenuation element. The resulting attenuation device comprises a first and a second single-mode fiber with expanded optical cores assembled facing each other in a capillary containing a liquid crystal forming attenuation means.
