Abstract
The utility model relates to a circular optical cable of banding relates to the optical cable that is used for communication. A strip-shaped round optical cable is provided with an optical fiber unit and a wrapping layer, wherein the cross section of the wrapping layer is round, and the optical fiber unit is arranged in the wrapping layer; the optical fiber unit is formed by overlapping a plurality of layers of optical fiber ribbons with the same specification, and the cross section of the optical fiber unit is rectangular. The outer surface of the optical fiber unit is provided with a longitudinal cladding; the longitudinal cladding layer is a strip-shaped plastic film. The wrapping layer is sequentially provided with an inner sheath, an aramid fiber layer and an outer sheath from inside to outside. The inner sheath is made of flame-retardant foaming material. The outer sheath is made of flame-retardant materials. The optical fiber ribbon is 12-core single-mode optical fiber, and the number of the optical fiber ribbon is 8. The flexible corner protection strip is arranged at the corner of the optical fiber unit and used for preventing the optical fiber unit from being extruded; and can be used as a ripcord when the optical fiber unit is stripped.
Description
Technical Field
The utility model relates to a circular optical cable of banding relates to the optical cable that is used for communication.
Background
With the rapid development of informatization wave, the optical cable plays an increasingly important role in the communication process, and as an important medium for information transmission, the information transmission amount of the optical fiber is important, and in the face of more and more massive information, the existing single-core optical cable has the trend of catching the forever in transmission capability, and a plurality of single-core optical cables are simply bundled together for use, so that the optical cable is easy to loosen and has low tensile strength, and the outer wall of the optical cable is easy to damage, so that the optical cable with large-capacity communication capability is necessary to be provided to meet the increasing use requirement, and the optical cable is better served for broad users.
