Buried optical cable

Abstract

The invention discloses a buried optical cable, which comprises a protecting bush. A base is arranged on the lower end of the protecting bush; an inserting block is arranged on the lower end of the base; a protecting plate is arranged on the upper end of the protecting bush; a reinforcing rib is arranged in the middle part of the upper end of the protecting plate; reinforcers are respectively arranged on two ends inside the protecting bush; two connecting strips are arranged between the two reinforcers; a cylindrical core is arranged in the middle in the protecting bush; an optical fiber placement layer is covered outside the cylindrical core; optical fiber is placed in the optical fiber placement layer. According to the buried optical cable provided by the invention, through the matching of a limiting slot and a limiting lug, the protecting bush can be well fixed on the base; through the reinforcers on two ends of the protecting bush, the overall strength can be effectively improved; the reinforcers can be made of conductive materials, and the two connecting strips are made of non-conductive materials, so that an electroshock proof function is realized in the protecting bush. The buried optical cable provided by the invention does not need to arrange lightning-protection wires additionally, is time saving, high in strength, good in tensile resistance effect, and suitable to be popularized.

Description

technical field [0001] The invention relates to the technical field of optical cables, in particular to a buried optical cable. Background technique [0002] Buried optical cable is a kind of optical cable buried underground. It is usually used in urban roads, wild mountains, expressways and other areas where only underground cables can be routed. The current buried optical cable has poor lightning protection performance and structural stability. Not good enough, the strength is low, and it is prone to damage after long-term use. For this reason, we propose a buried optical cable to solve the above problems. Contents of the invention [0003] The object of the present invention is to propose a buried optical cable in order to solve the shortcomings in the prior art. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: [0005] A buried optical cable, comprising a sheath, the lower end of the sheath is provided wit...
