Self-supporting butterfly-shape optical-electrical hybrid cable

Abstract

The invention relates to a self-supporting butterfly-shape optical-electrical hybrid cable. The cable comprises a suspension wire coating layer (1), a butterfly sheath (2), a suspension wire (4), leads (5) and optical communication unit (6). The suspension wire coating layer (1) is connected with the butterfly sheath (2) through a connection portion (3). The suspension wire (4) is arranged in the suspension wire coating layer (1). The butterfly sheath (2) and the optical communication unit (6) are arranged in the butterfly sheath (2). The optical communication unit (6) is two single-core fibers. A cross section of the butterfly sheath (2) is in a rectangle shape. Two sides of the rectangle cross section are provided with V-shape grooves which are extended parallelly along a vertical direction. The leads (5) are laid on the two sides in the butterfly sheath (2) respectively. The cable of the invention has the advantages that self-supporting strength is high; a optical signal transmission demand and a power supply demand are satisfied; laying operation is simple; labor saving and time saving are achieved; good mechanical performance is possessed.

Description

Technical field [0001] The invention relates to a cable, in particular to a self-supporting butterfly-shaped photoelectric hybrid cable. Background technique [0002] With the vigorous rise of communications, data services, especially IP services, are growing exponentially. Multimedia such as voice, data, and images need to be transmitted, so larger network capacity and wider bandwidth are required. How to connect users to the high-speed, large-capacity backbone network through high-bandwidth and high-quality access methods is of decisive significance for the successful realization of the information superhighway. However, existing optical cables or cables all have a defect, that is, they can only transmit optical signals or electrical signals respectively. However, in many occasions that require simultaneous optical and electrical signal transmission, only separate optical cables and cables can be connected, and corresponding equipment needs to be added. Therefore, the system ...

Problems solved by technology

However, most of the common photoelectric hybrid cables are layer-twisted structures in which the optical unit and the metal wire unit are twisted in layers in a cable core. This structure using the same cable core not only affects the flexibility and economy of the configuration of each unit in the cable. , and it also brings inconvenience to the divergence of photoelectric units in the middle of transmission

[0004] Chinese patent application number: 201220363366.1 discloses a photoelectric hybrid corrugated cable, including an optical communication unit, an electrical communication unit and an outer sheath, the optical communication unit includes at least a pair of optical fiber cores, and the electrical communication unit includes at least one electrical communication link The corrugated cable with this structure has poor bearing and tensile capacity, and most of the cable is exposed to the outside air. After long-term sun and rain, the protective effect of the outer sheath of the cable Small
