Along with EPON EPOU, GPOU technology are day by day ripe, the FTTH network layout is surging forward, and is widely used in business premises, residential quarters and industrial park, and it has comprehensive functions such as carrying high speed Internet access, VoIP, IPTV.Transmission medium is an optical cable in the FTTH line construction, comprises feeder line optical cable, optical distribution cable, the optical cable of registering one's residence.General feeder line optical cable and optical distribution cable adopt outdoor optical cable more, and the optical cable of registering one's residence adopts inside cable.
At present, outdoor optical cable enters building, adopts common layer-twisted type or central tubular optical cable more, and its reinforcement adopts phosphatization steel wire or nonmetal making, and all fills the interior loose sleeve pipe of cable with the fine cream that blocks water, and cable cream is filled the cable core slit, is used for preventing the invasion of moisture.Since in the Connectorized fiber optic cabling fine cream, cable cream are arranged, the cleaning when the influence construction continues, and fine on the other hand cream cable cream all belongs to combustible material, by the outdoor building that enter, has potential safety hazard.
Inside cable also has branched cable and optical distribution cable except the butterfly leading in cable.The butterfly leading in cable is mainly used in the FTTH optical cable of registering one's residence, at present extensively utilization have only 1 core or 2 cores, it is simple in structure, is difficult for making big core number; Branched cable is used for indoor vertical wirings, is easy to branch and independently uses, and can bear bigger mechanical pulling force, and it surpasses 12 cores needs repeatedly stranding, and structure is more too fat to move, and the cable footpath is bigger; Optical distribution cable is mainly used in the indoor horizontal wiring, and the cable footpath is thinner, and its cable inner structure is looser, and the optical fiber ordering is chaotic, is looked for fibre to make troubles, and is difficult for bearing bigger mechanical pulling force and flat pressure.
No matter outdoor optical cable, be built on stilts laying if being registered one's residence, still utilize pipeline laying, all requires cable outer diameter little, and in light weight, anti-flammability is good, nonmetal full medium; The optical cable of registering one's residence is also pliable and tough, and can bear certain pulling force and pressure.
Summary of the invention
The purpose of this utility model is in order to solve the deficiency of above-mentioned technology, to provide a kind of simple and reasonable, in light weight, with low cost, and the cable external diameter is little, and it is high that density of optic fibre is wanted, and look for fibre, divide easily fine, Connectorized fiber optic cabling easy to maintenance.
The utility model solves the scheme that its technical matters takes: a kind of Connectorized fiber optic cabling; comprise subelement, central reinforce member, reinforcing band, oversheath; the end face that it is characterized in that subelement is and has scalloped recess and be symmetrically distributed in circle on the circumference; be provided with optical fiber and reinforcement in the subelement; subelement is stranded around central reinforce member; its outside is provided with waterstop; the outside of waterstop vertically is provided with the aramid fiber reinforcing band; the reinforcing band outside is provided with the oversheath protective seam, is placed with one and tears rope between reinforcing band and oversheath.
Described subelement inner fiber places the circular end surface center, and outer fiber is distributed with two non-metal reinforcement members, two non-metal reinforcement member symmetries, and its line is perpendicular with the line of centres of circular last two scalloped recess; The cone angle of described scalloped recess is 34 °～38 °, and the cone angle top is 0.7mm apart from optical fiber.
The utility model is reasonable in design, and compact conformation is easy to manufacture, and cost is low, and is in light weight, and pliability is good, and the core number is big, can be used for outdoor optical distribution cable, also can be used for indoor multi-usage wiring.Owing to vertically be provided with the aramid fiber reinforcing band in the Connectorized fiber optic cabling, increased tension, the compressive strength of optical cable, mechanical property improves, and can prevent from effectively also when being used for pipeline laying that the mouse ant from nibbling to hinder cable core.
Below in conjunction with drawings and Examples the utility model is further specified.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Mark among the figure: 1, reinforcement, 2, optical fiber or fibre ribbon, 3, scalloped recess, 4, subelement, 5, central reinforce member, 6, tear rope 7, water blocking yarn, 8, waterstop, 9, reinforcing band, 10, oversheath.
Embodiment:
