    Abstract: Provided is an optical fiber ribbon capable of achieving higher density and reduction in diameter and accurately placing optical fibers in V-shape grooves in a fusion machine without failure. The optical fiber ribbon 1 includes three or more of optical fibers 2 arranged in parallel and connecting portions 3 connecting adjacent two optical fibers 2 together, the connecting portions 3 being intermittently provided in each of a ribbon longitudinal direction and a ribbon width direction. The connecting portions 3 are each formed in such a manner as to fill resin into a gap S formed between adjacent two optical fibers 2, and both surfaces of the respective connecting portions 3 are each formed into a recess having a concave shape curved toward a center of the gap S to separate from lines 4,5 each connecting contact points of the optical fibers 2 when being placed on a horizontal surface.

    Abstract: It is an object of the present invention to suppress a coating resin from being shaved off in an event where optical fibers are sent out from a coating dice. When a Young's modulus of ultraviolet curable resins 13 located on outermost layers of optical fibers 3 is 300 MPa or more, and the Young's modulus is 300 MPa to 600 MPa, a plurality of the optical fibers 3 in which friction force measured by the following measurement method is 0.3 N or less are arranged in parallel to one another, these respective optical fibers 3 are fixed to one another intermittently along a longitudinal direction thereof, and adhered portions 5 are formed.

    Abstract: An optical fiber cable of the present disclosure is formed by assembling a plurality of drop optical cables, and each of the drop optical cables has a structure where at least one or more optical fiber cores and a tension fiber or a tension member is embedded in a sheath such that the drop optical cable has two or more axes each having a minimum value of a second moment of area with respect to arbitrary neutral planes, and even an optical cable obtained by assembling drop optical cables has a structure having two or more axes each having a minimum value of the second moment of area with respect to arbitrary neutral planes.

    Abstract: An object is to provide a closure with a structure having a drainage function to eliminate water immersion into a coated optical fiber against temporary flooding and to prevent water from continuously contacting the coated optical fiber. Another object is to provide a closure with improved workability for opening and closing.
    A closure according to the present invention protects a connection part that connects a coated optical fiber enclosed in a optical fiber cable with a coated optical fiber enclosed in a optical fiber cable. The closure includes a coated optical fiber housing that divides an interior of the closure into a first space that is on a side of a road and has a main body cable insertion hole for inserting the optical fiber cables from an exterior and a second space that is on an opposite side of the road and includes the connection part. The coated optical fiber housing has a frustum shape with two bases each open and a base with a smaller area of the two bases protruding toward the side of the road. The base with the smaller area of the two bases is a cable insertion hole for inserting the optical fiber cable from the first space into the second space and is not in contact with a bottom surface of the first space on the side of the road.
