Abstract: An improved optical cable (10) having increased bending flexibility along with increased tensile strength comprises means for controlling coupling between a cable jacket (28) and its reinforcing strength members (26). In one embodiment, a reinforcement bedding layer (23) is applied between a plastic-extruded inner jacket (22) and the outer cable jacket (28). Before extrusion of the outer jacket (28), the reinforcing strength members (26) are helically applied onto the bedding layer with predetermined strength member surfaces (27) making intimate surface contact with the bedding layer. Because the bedding layer is impervious to the plastic extrudant used to construct the outer jacket and is capable of rendering the predetermined strength member surfaces sufficiently inaccessible to the plastic extrudant, encapsulation of strength member lengths (25) containing the predetermined strength member surfaces (27) by the plastic extrudant is prevented. In another embodiment, the cable sheath (57) includes two separate layers (64, 70) of strength members, each layer having predetermined lays in opposite directions such that under a tensile load they produce equal but oppositely directed torques about the cable's longitudinal axis. The coupling between each layer of strength members and its surrounding jacket can also be controlled.

Abstract: An optical fiber demultiplexer comprises first (325b) and second (325c) ports located in the focal plane of a first spherical reflective surface (313) such that light at one port is focused on the other. A second spherical reflective surface (315) which is dichroic is located between the ports and the first spherical surface and has a focal plane common with that of the first spherical surface. A third port (325a) is located in the common focal plane such that light from the first port of the frequency reflected by the dichroic surface is focused at the third port (325a).

Abstract: 57 Multifilament bundles are impregnated with an ultraviolet curable resin to form a composite material suitable for use as a strength member in cables and other applications. The inventive coatings obtain good wetting of the filaments, allowing rapid penetration into the roving or yarn. A much faster coating and curing operation is obtained as compared to prior art methods. Fiberglass strength members made by this technique are especially advantageous for use in optical fiber cables where high strength and a low thermal coefficient of expansion are desired, as well as nonconductivity to protect against lightning strikes.

Abstract: A light conduction apparatus for photosynthetic reaction includes a rotatable light distributor which may be a transparent rod or disc. Converged light is guided by a solid or tubular light conducting member into the light distributor and routed along at least one optical path through the tight distributor as far as a radiation surface of the latter. The light output from the radiation surface is applied a moment to each of a number of light conducting rods, which lead to a confinement for photosynthesis, once for each full rotation of the light distributor. Thus, the confinement shares a single light source which can be small size for given dimensions of the confinement.

Abstract: An individually armoured fiber optic core assembly (10) having a diameter not greater than 0.050" (1.72 mm) is provided as well as a process for making same. A fiber optic core (11) comprising a fiber optic element (12) and a surrounding protective layer (13) is encased within a drawn metal sheath (14) having a generally longitudinally extending seam (15). The ratio of the outside diameter of the fiber optic core (11) to the inside diameter of the metal sheath (14) is at least about 0.6:1. The fiber is formed by drawing metal strip (32') through a die (36) and simultaneously laying the core into the sheath as it is formed by the die. Optionally the sheath can be sealed by a line of solder applied along the length of the seam. Fiber optic cables comprising a plurality of individual fibers according to the invention are also described.
