摘要： The invention relates to high-strength, abrasion-resistant optical fiber cable having a supplemental layer consisting essentially of a liquid crystal polymer (LCP) to enhance the cable's tensile strength and hermetically seal it, and an outermost encasing layer to protect the LCP supplemental layer from damage that could otherwise diminish the tensile strength or destroy the moisture barrier properties of the cable gained by adding the supplemental liquid crystal polymer layer. The encasing layer is preferably a thin layer of a smooth, non-crystalline thermoplastic that can be easily removed with chemicals that do not affect the properties of the supplemental layer so that the supplemental layer can be made accessible for promoting the formation of hermetically sealed interfaces between the cable and other structures. Cross-head extrusion methods for coating optical fibers with LCP and encasing layers are described along with laser and ultrasonic bonding techniques for fabricating hermetic packages.

摘要： To determine the radial profile of the refractive index of a substantially cylindrical transparent object such as an optical fibre or optical fibre preform, the object is illuminated with a collimated beam of light incident at an angle to the axis of the cylindrical object differing substantially from 90 degrees and measuring the refraction angle at which light leaves a substantially plane endface as a function of the radial position on the endface.

摘要： An improved method for forming optical fiber preforms by the chemical vapor deposition technique utilizes an elongated burner having an array of burner orifices that forms an elongated silica particle stream having a thickness generally related to the diameter dimensions of a cylindrical preform starter rod. The burner can be formed as an elongated plate having the array of gas ports that produce the desired or silica stream. As a consequence, high initial silica particle deposition rates are obtained compared to prior methods utilizing circular burners, with the high initial deposition rates maintained throughout preform fabrication to result in an increase in preform production rates with an accompanying reduction in costs.

摘要： An optical fiber preform is formed by plasma chemical vapor deposition utilizing a plasma torch that includes a chamber into which a plasma starting gas, such as argon, is introduced and converted to a plasma by application of high frequency electromagnetic energy. A suitable entry port is provided in the torch chamber to allow dopant material in solid form to be introduced directly into the plasma for vaporization or ionization. The dopant material passes into a lower temperature region where gaseous silica precursor gases are introduced to undergo reaction in the presence of the vaporized dopant to form appropriately doped silica particles for deposition onto a substrate. Solid dopants of low volitility or vapor pressure may be used as dopants which could not otherwise be used in vapor deposition processes. The absence of hydrogen in the reaction dynamics results in a preform having greatly reduced hydroxyl ion content. If desired, a high-purity starting glass, rather than the precursor gases, can be introduced directly into the plasma to form the appropriately doped material.
