Abstract
Optical cable. The utility model provides a simple structure improves life's optical cable. Optical cable's cross -section is the ellipse, including PVC sheath, kevlar silk and a pair of optic fibre, optic fibre include the fibre core with and seal the PE sheath outside the fibre core, a pair of optic fibre is established symmetrically in the PVC sheath, the kevlar silk is established in the PVC sheath, and be located between a pair of optic fibre. The utility model discloses set up the kevlar silk in optical cable, strengthened optical cable's tension stress and compliance, a pair of optic fibre is connected through gomphosis structure (being the sawtooth gomphosis), has improved joint strength between them, forms wholly, has improved life. The utility model provides an optical cable is with low costs, light in weight and tensile can the reinforces.
Description
Technical field
The utility model relates to communication technical field, particularly relates to optical cable.
Background technology
Optical cable is that the optical fiber of some forms the cable heart according to certain way, is surrounded by sheath outward, the also coated outer jacket had, in order to realize a kind of communication line of optical signal transmission.Along with informationalized development, the conveying capacity of information increases rapidly, and optical fiber cable obtains a large amount of application.The cable configuration used at present is comparatively simple, this optical cable is made up of single core tight tube fiber and the restrictive coating being coated on single core tight tube fiber surface, the production technology of this optical fiber is comparatively simple, the bad mechanical property of optical fiber, in construction or use procedure, easily cause the bending of optical fiber or fracture, finally cause the Transmission of light signal, have a strong impact on the long-time stability of optical fiber transmission property.
Utility model content
The utility model, for above problem, provides a kind of structure simple, improves the optical cable in serviceable life.
The technical solution of the utility model is: the ellipsoidal cross section of described optical cable, comprise PVC sheath, Kevlar fiber and a pair optical fiber, described optical fiber comprise fibre core and and the PE sheath that is encapsulated in outside fibre core, optical fiber described in a pair is located in described PVC sheath symmetrically, and described Kevlar fiber to be located in described PVC sheath and between a pair optical fiber.
Connected by embedded structure between the PE sheath of a pair optical fiber, described embedded structure is: the inner side of a pair PE sheath is respectively equipped with the sawtooth staggered.
Described Kevlar fiber is located at the one or both sides of a pair optical fiber.
Described fibre core material is polymethylmethacrylate.
Described PE sheath is provided with the storage tank placing Kev wire drawing.
The utility model arranges Kevlar fiber in optical cable, enhances tension stress and the flexibility of optical cable; A pair optical fiber is connected by embedded structure (namely sawtooth is fitted together to), improves both strength of joint, is formed overall, improve serviceable life.Optical cable cost in the utility model is low, lightweight and resistance to tension is strong.
