Optical transport fibre and method for producing same

摘要

An optical fiber for transmitting laser beams includes at least one fiber core, at least one fiber jacket, a sheath encompassing the fiber jacket, an interlayer between the fiber jacket and the sheath, in which the refractive index of the interlayer is lower than a refractive index of the corresponding fiber jacket that is in contact with the interlayer, and an outputting means for outputting leakage radiation from the fiber.

主权项

1. An optical fiber comprising:
at least one fiber core; a first fiber jacket; a sheath encompassing the first fiber jacket; an interlayer between the first fiber jacket and the sheath, wherein a refractive index of the interlayer is lower than a refractive index of the first fiber jacket; a plug positioned near an end of the optical fiber, the plug being arranged around a contact spot on the optical fiber and being connected to the optical fiber by an adhesive that contacts the interlayer along a longitudinal direction of the optical fiber, wherein the interlayer prevents radiation from escaping the fiber at the contact spot; and at least one outputting means device for outputting radiation out of the first fiber jacket.
