Embodiment Construction

[0031] The present invention will be further described below in conjunction with the embodiments and accompanying drawings.

[0032] This embodiment is an easy-to-lay aerial optical cable with a length measurement function and a manufacturing method thereof. figure 1 It is a cross-sectional schematic diagram of the easy-to-lay aerial optical cable with the function of length measurement. The easy-to-lay aerial optical cable with the function of length measurement is composed of optical fiber 1, optical cable filling paste 2, loose tube 3, expansion water-blocking type cable paste 4, and yarn binding layer 5 , metal composite belt layer 6, sheath 7, central reinforcement 8, reinforcement cushion 9 and filling rope 10. 6-12 optical fibers 1 are placed in the loose tube 3 to form an optical fiber unit, and the gap between the optical fiber in the loose tube 3 and the inner wall of the loose tube is filled with the cable filling paste 2 . Centering on the central strength member ...

Abstract

The invention belongs to the technical field of cables and relates to an easily-laid overhead cable with a length metering function and a manufacturing method of the easily-laid overhead cable. 6-12 fibers are arranged in a loose tube so that a fiber unit is formed. Gaps in the loose tube are filled with cable filling paste. 4-8 fiber units and filling ropes surround a central reinforcement piece. By lapping a yarn bundling layer, a cable core with a circular cross section is formed. Gaps in the cable core are filled with expansion water-resisting type cable paste. A metal composite belt layer is lapped on the yarn bundling layers outside the cable cores. A sheath is arranged on the metal composite belt layer in an extruded manner. Annular hook grooves are arranged in the outer surface of the sheath in pressed manner at equal intervals. According to the invention, by use of nylon, the cable is capable of resisting wear, acid and alkali, light and good in mechanical performance, so transmission of signals is ensured; the hook grooves are distributed in the cable at equal intervals, so the cable has the length metering function; the hook grooves are simple in design and easy to install, so the cable is quite firm during laying, construction efficiency is improved and transmission of signals is ensured; and the cable is suitable for transmission of signals in mountain and forest regions and relatively large-span far-distance signals.

Description

technical field [0001] The invention belongs to the technical field of optical cables, and in particular relates to an easy-to-lay aerial optical cable with a length measurement function and a manufacturing method thereof. Background technique [0002] Aerial optical cable is to use the original electric pole to realize overhead hanging of communication optical cable. It is a construction method for special optical cable and optical cable laying in special areas. Aerial optical cable has strong adaptability and has relatively good performance in various natural environments. Working performance, aerial optical cables have good application performance, and are often used for laying communication optical cables below the second level. [0003] During the installation process, the appropriate hook is selected according to the type of optical cable and the size of the outer diameter, and then they are connected in series and hung on the suspension wire. Because the hook is "eas...
