The present disclosure relates to an optical fiber ribbon, which is a component included in a high-density optical fiber cable including high-density optical fibers (which are installed in a limited space such as a conduit line) per unit area to build a large-capacity communication network, in which bonding of optical fibers is maintained to allow the optical fibers to be rolled in a width direction, and which is configured to achieve an optimal separation force on each bonding region in a longitudinal direction of the optical fibers and a direction perpendicular to the optical fibers, thereby improving workability in splitting or connecting the optical fiber ribbon and preventing inadvertent separation of the optical fibers of the optical fiber ribbon during the manufacture of the optical fiber cable.

Optical fiber ribbon

The present disclosure relates to an optical unit including a tubular member, which accommodates a plurality of optical fibers and whose shape is variable to achieve an optimal space factor, to minimizes optical loss or the deterioration of optical properties when the optical cable is bent or compressed or external impact is applied, secure waterproof performance, and minimize an outer diameter, and an optical cable including the same.

Optical cable

An optical cable is provided in which an optical fiber bundle with clustered or bundled optical fibers is accommodated in a tubular member and the optical fibers are formed in an excess group length (EGL) by modeling considering bending properties of the optical cable or a lossless bending radius of the optical fibers of the optical fiber bundle, thereby minimizing stress, damage or optical loss of the optical fibers in the optical fiber bundle.
