Abstract: A method to skew or deskew a plurality of optical channels in a multichannel optical cable which includes the steps of determining an optical pulse transmission time in at least a first channel and a second channel of the multichannel optical cable. A relative pulse delay between the first channel and the second channel of the multi-channel optical cable is calculated. Delay optics with the appropriate relative pulse delay are serially optically connected to at least one of the channels to one of skew or deskew the first channel relative to the second channel.

Abstract: A flexible image-conducting bundle of optical fibers is produced by juxtapositioning and drawing a multiplicity of glass-clad glass fiber preforms and interstitial rods of leachable glass. The drawn assembly is cut to desired length and interstitial glasses are leached from the intermediate portion of the cut piece.

Abstract: A plurality of optical glass cores of selected refractive index and dimension are clad with a first glass of lower refractive index providing substantially total internal reflection within the cores. The clad cores are then clad with a glass displaying a lower viscosity than either the core or the first cladding and fused into a final assembly. The cross-sectional area of the second core cladding is selected to provide a minimum free space within the fused assembly.

Abstract: A leached fiberscope formed of a multiplicity of optical fibers each surrounded by a stray light absorber adjacent opposite ends of the fiberscope. This light absorber is formed by adding a light-absorbing constituent to leachable overcladdings initially provided on the optical fibers which are retained adjacent opposite ends of the fiberscope as the absorber and removed from intermediate portions of the length of the fiberscope to render it flexible.

Abstract: A fiber optic image transporting device for converting the shape of optical images directed thereinto. The device is formed of an initially rigid multifiber conduit having a leachable fiber connecting matrix. The matrix is removed from one end of the conduit and replaced with a fiber bonding resin. The intermediate portion of the conduit is then leached, keeping its opposite end intact as one image transmitting face of the device, and the resin bonded end is cut into sections of predetermined shapes and sizes which are reassembled to form a differently shaped second image transmitting face.
