OPTICAL FIBER RIBBON AND SLOT-LESS OPTICAL CABLE

Abstract: the present application discloses an optical fiber ribbon () in which a plurality of single-core coated optical fibers () are intermittently connected or separated in a length direction and a width direction while the plurality of single-core coated optical fibers () are connected to each other in units of one or two cores. in the optical fiber ribbon (), conditional expressions [] and [] are satisfied, where a is the thickness of a cross section of a connection part (), b is the outside diameter of the cross section of the connection part (), a is the length of the connection part () in the longitudinal direction, and b is the length of a separation part () in the longitudinal direction. [1]: 10 mm≤a/b*a≤35 mm. [2]: 40 mm≤b≤125 mm.
