Abstract

The invention discloses a C-type-sleeve all-dielectric self-supporting optical cable used for an access network. The optical cable comprises a light unit portion and a bearing component portion. The bearing component portion is a C-type protection sleeve which sleeves an outer portion of the light unit portion. A contact surface of the C-type protection sleeve and the light unit portion is a ''C''-shaped structure. FRP is filled in the C-type protection sleeve. The FRP is arranged at a near open end of the C-type protection sleeve and is served as a reinforcement component of the C-type protection sleeve. In the invention, the brand new C-type self-supporting protection-sleeve all-dielectric self-supporting optical cable used for an access network is exploited. By using the optical cable, manufacturing cost and construction cost of the optical cable are reduced and the novel optical cable with a low price and stable performance is created.

Description

technical field [0001] The invention relates to the field of optical cables, in particular to a C-type sleeve dielectric self-supporting optical cable for an access network and a preparation method thereof. Background technique [0002] Since the self-supporting optical cable does not need to erect steel strands and installation hooks when laying overhead, it has the characteristics of simple laying and low construction cost. It is widely used in long-distance transmission or high-altitude laying, and further optimizes the existing self-supporting optical cable. The structure is an important way to broaden the application of self-supporting optical cables and optimize the working state of self-supporting optical cables. [0003] The traditional self-supporting aerial optical cable is to sheath the optical unit part (optical fiber, loose tube) and the load-bearing element part (aramid fiber, steel wire strand or FRP) in the same optical cable during the production process.
