    Abstract: The present disclosure relates generally to a positioning arrangement for positioning optical fibers. The positioning arrangement can include a positioning substrate with a plurality of fiber receiving locations arranged in a row. Each of the fiber receiving locations can be configured to receive one of the optical fibers. Each of the fiber receiving locations can include a first fiber contact surface and a second fiber contact surface that are each adapted to contact a corresponding one of the optical fibers when the optical fiber is received in the fiber receiving location. The first and second fiber contact surfaces of each of the fiber receiving locations can be relatively oriented to define a fiber receiving angle that is greater than 90 degrees. The positioning arrangement can also include a pressing structure with pressing surfaces for opposing the row of fiber receiving locations to press the optical fibers within the fiber receiving locations.

    Abstract: An optical fiber ribbon cable is formed using thermally expandable core (TEC) fibers. Expanded optical cores are formed in sections of TEC fibers, so that each section of TEC fiber comprises a first region having an unexpanded core, a second region having an expanded core, and a tapered region between the first region and the second region. The respective sections are cleaved to length and formed into a ribbon. A hybrid optical fiber ribbon cable can be made by fusing single mode optical fibers of a single mode fiber ribbon cable with TEC fibers of a TEC fiber ribbon cable using a laser. The laser is also used to form tapered core regions in the TEC fibers to reduce coupling losses between the TEC fibers and the single mode fibers.
