Abstract
The invention relates to an outdoor overhead butterfly-type introduced optical cable. The optical cable comprises an optical fiber (1), reinforcement components (2), a sheath (3) and an optical cable reinforcement suspension wire (4). The reinforcement components (2) are symmetrically distributed on upper and lower sides of the optical fiber (1). The sheath (3) is arranged on an outer side of the optical fiber (1), the reinforcement components (2) and the optical cable reinforcement suspension wire (4) in a plastic extruding mode. The reinforcement components (2) adopt a glass reinforcement fiber rod, an aramid fiber reinforcement fiber rod or a finer wire. The optical cable reinforcement suspension wire (4) adopts a high-carbon steel wire possessing a superior tensile ability or a steel strand. The sheath (3) adopts a LSZH or PVC flame retardation material. The optical fiber (1) adopts the optical fiber with performance that bending and losses are not sensitive. A minimum bending radius can be 15mm or even less. The optical cable of the invention adopts a high-altitude overhead mode to carry out laying and construction cost is low. The optical cable reinforcement suspension wire adopts the high-carbon steel wire or the steel strand so that a plurality of the optical cables can be hanged according to a need. Good extendibility and the superior tensile ability are possessed. The sheath adopts the LSZH or PVC flame retardation material and possesses good flame retardation performance.
Description
Technical field
The present invention relates to a kind of optical cable, particularly relate to outdoor built on stilts butterfly leading in cable.
Background technology
Along with the fast development of communication industry, communication network from single speech business to voice, the full-service integrated communication Information Network future development of data, video several data business, the construction of optical-fiber network is from backbone network, core net to Metropolitan Area Network (MAN), Access Network development.Because optical fiber has the characteristics such as bandwidth, transmission capacity is large, decay is little, Fiber to the home has the characteristics such as the multi-service of support, bandwidth is infinitely great, Operation Administration and Maintenance is convenient, a kind of butterfly indoor leading-in optical cable has appearred in the market, such as application number 201220420949.3, this leading in cable comprises optical fiber, non-metal reinforcement member and oversheath, oversheath parcel optical fiber and non-metal reinforcement member, but the non-metal reinforcement member of this leading in cable must be enough to bear the weight of optical cable, cost is high, poor expandability can't be carried additionally the second optical cable according to demand.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, the outdoor built on stilts butterfly leading in cable that a kind of extensibility is good, construction cost is low, friction is little is provided, this optical cable is soft, good bending property, has good anti-flammability and have superior tensile property when outdoor application.
The objective of the invention is to be achieved through the following technical solutions: outdoor built on stilts butterfly leading in cable, it comprises optical fiber, stiffener, sheath and optical cable reinforcement messenger wire, stiffener is symmetrically distributed in up and down both sides of optical fiber, and the sheath extrusion molding is strengthened the messenger wire outside at optical fiber, stiffener and optical cable.
Described stiffener adopts fiberglass reinforcement rod, aramid fiber fortifying fibre rod or finer wire; Described optical cable is strengthened messenger wire and is adopted high-carbon steel wire or the steel strand wires with superior resistance to tension; Described sheath adopts LSZH or PVC fire proofing; The both sides medium position of described sheath is respectively arranged with the V-type groove; Described optical fiber adopts the insensitive optical fiber of bending loss, and minimum bending radius reaches 15mm even less.
The invention has the beneficial effects as follows: adopt the built on stilts mode in high-altitude to lay, construction cost is low; Be provided with optical cable and strengthen messenger wire, this messenger wire adopts high-carbon steel wire or steel strand wires, can hang according to demand many optical cables, is with good expansibility and superior resistance to tension; Sheath adopts LSZH or PVC fire proofing, has good fire resistance and environmental protection; Optical fiber adopts the insensitive optical fiber of bending loss, and minimum bending radius reaches 15mm even less; The both sides medium position of sheath is respectively arranged with the V-type groove, is convenient to peeling off of optical fiber.
