摘要： Provided are an optical fiber ribbon and an optical fiber cable which prevent cracks of a connection and detachment of the connection from a colored optical fiber core when the optical fiber cable is subjected to repetitive ironing and which does not impair characteristics of the cable at the time of high-density cabling.
In the present invention, an optical fiber ribbon 2 is intermittently connected in a length direction by an intermittent connection 3 which includes a polyol having a weight-average molecular weight of 3000 to 4000 in a specific amount relative to the entire intermittent connection 3 and which has Young's modulus at 23°C within a specific range. Therefore, when collectively unitizing optical fiber ribbons 2 to form an optical fiber cable, the present invention provides an optical fiber ribbon 2 which maintains advantages of the optical fiber ribbon 2 and which prevents cracks of the intermittent connection 3 and detachment of the intermittent connection 3 from a colored optical fiber core 1 when the cable is subjected to repetitive ironing. The present invention also provides an optical fiber cable provided with the optical fiber ribbon 2.

摘要： A coated fiber strand includes one or more coating layers located directly or indirectly on the strand and at least one heterogeneous region present in or on one or more of the coating layer(s). The heterogeneous region(s) preferably comprises a material useful for coding of the fiber. One particularly preferred embodiment relates to an optical fiber having a primary coating layer and a secondary coating layer where the heterogeneous region(s) defines one or more colored stripes in or on the secondary coating layer. A method for forming a coated fiber, such as an optical fiber, includes introducing at least one coating layer onto a fiber strand such that one or more coating layers directly or indirectly cover at least a portion of the surface of the strand. The method further includes introducing at least one heterogeneous region into or onto a coating layer(s). The fiber can then be treated, e.g., cured so as to provide a desired product. By this method, a desired functionality, e.g., coding, can be introduced onto a fiber without adversely effecting subsequent processing steps, e.g., curing of the coating layer(s).

摘要： A nitrogen injection assembly for use in coloring and curing optical fibers is disclosed. The nitrogen injection assembly includes a cover section and a distribution seal. An optical fiber coated with ink passes from a coating die to a curing chamber via a passageway defined by the cover section and the distribution seal. The distribution seal injects nitrogen into the passageway to keep the coated fiber and the curing chamber substantially free of oxygen. With the distribution seal positioned closer to the curing chamber than the cover section, the apparatus minimizes the risk of leaks in the passageway and the number of required seals.

摘要： The present invention provides coating methods for use in the manufacture of coated optical fibers. The coating methods of the present invention coat an optical fiber (12) with a primary coating material (34) that has a non-reactive colorant. A secondary coating material (36) is applied over the primary coating material. The primary coating material may either be cured prior to application of the secondary coating material or both the primary and secondary coating materials may be cured at the same time to create primary and secondary coating layers over the optical fiber. In one embodiment, the secondary layer is formed of a substantially transparent material, visibly exposing the colored primary coating layer for inspection and/or measurement (24). In this process, there is a first coating system (20a) and curing stage (26a) for applying and curing a primary layer and a second coating system (20b) and curing stage (26a) located after the first coating system and curing stage for applying and curing a secondary layer. The coating method may be used in a "wet on wet" or "wet on dry" manufacturing process.

摘要： An optical fibre with a coloured coating, in particular a primary coating, is described, together with a polymer composition for said coating in which an organic dye is dissolved in the base cross-linkable mixture. The optical fibres of the invention show a lesser signal attenuation and a more stable primary coating coloration with the passage of time.

摘要： An apparatus for coloring optical fibers, includes: a first reservoir for containing a natural coating material to be applied onto an optical fiber being drawn; a second reservoir for containing a colorant to be mixed with the natural coating material; a mixer in fluid communication with the first and second reservoirs to receive a first flow of natural coating material and a second flow of colorant and to mix the first and second flows to obtain a colored coating material; a coating die in fluid communication with the mixer to receive the flow of colored coating material and to apply it onto the optical fiber being drawn. A first gas pressure source is associated with the first reservoir, exerting on the natural coating material a first gas pressure variable as a function of at least one optical fiber drawing parameter, and a second gas pressure source is associated with the second reservoir, exerting on the colorant a second gas pressure variable as a function of at least one optical fiber drawing parameter. The first and second lines have relevant pressure drop in a ratio corresponding to the ratio of natural coating material and colorant providing the colored coating material.
