Abstract
The present disclosure relates to an optical fiber ribbon that provides a high-capacity communication network, is capable of being rolled in a width direction so as to efficiently use a space in a conduit, minimizes separation between ribbons constituting the optical fiber ribbon or damage to optical fibers during a rolling process, and facilitates overall connection or branching at a connection end.
Claims16
An optical fiber ribbon formed by bonding a plurality of optical fibers in parallel to each other, wherein
- each pair of adjacent optical fibers among the plurality of optical fibers is bonded to each other through a plurality of bonding parts disposed at predetermined intervals in a longitudinal direction of the optical fiber, and
- in the longitudinal direction of the optical fiber, a length of each of the bonding parts is 5 mm to 15 mm, a period of the bonding parts is 10 mm to 90 mm, and a length of a non-bonding part is 5 mm to 75 mm,
- wherein the period (P) of the bonding parts is a sum of the length (a) of each bonding part and the length (c) of the non-bonding part, wherein a coupling rate is given by:
