Each connector is structurally characterized in that the single-core butterfly-shaped optical cable is connected with a back end of a metal tail handle, and the front end of the metal tail handle is connected with the back end of a ceramic insertion core after being sleeved with an SC (square connector) main body and a spring; an optical fiber fibril and a blue core wire which are covered by a stiffener penetrate through a centre hole of the metal tail handle, the optical fiber fibril is connected with the ceramic insertion core; a joint of the single-core butterfly-shaped optical cable and the metal tail handle is in protective fixed connection by an aluminum riveting component, and the joint is sleeved with a plastic sheath; the SC main body is connected with the back end of a plastic inner frame in an embedding mode, so that a connection head which consists of the ceramic insertion core, the metal tail handle, the aluminum riveting component and the single-core butterfly-shaped optical cable is movable relative to the plastic inner frame. The butterfly-shaped optical cable jump fiber disclosed by the invention has the advantages that a hard optical fiber is used as the jump fiber, the optical fiber fibril is protected more effectively, threading and connection are convenient, bending is not overlarge, signals can not be attenuated, and a ready-mad jump fiber is provided for the last section of FTTH (fiber to the home).
Description
Technical field
The present invention relates to optical-fibre communications equipment technical field, specifically, is a kind of hard optical cable---butterfly optical cable jumping fiber using in Fiber to the home (FTTH).
Background technology
Optical fiber technology is very general in the application of China, and Fiber to the home (FTTH) is one of best measure of efficiency in current fiber optic applications, and it need to use many optical fiber dispensing apparatus and parts.Realize after Fiber to the home, family's broadband access ability can surpass 100 megabits per second, and the effect of its application is very obvious.
Outdoor optical cable is switched in the each household resident family of residential quarters and will and continues through a series of fiber distribution, at present, in city or population concentration occupy residence and adopt floor distributing cabinet to realize more, in Fiber to the home process, to use a large amount of tail optical fibers and jumping fiber.From the fibre-optic terminus to family, to what still will connect with optical fiber concrete equipment, that is, in user family, also also has the demand of fibre junction.To this, the method adopting is at present, connects joint make jumping fiber and use with flexible optical cable.But, because flexible optical cable consists of the outer coating (sheath) of optical cable, virtue wheel, white heart yearn and optical fiber, the problem that the jumping fiber made from soft fiber (seeing accompanying drawing 1) easily produces is: 1. because of line body too soft when doing engineering cross-under sometimes inconvenient, while wearing especially from lower to upper; 2. flexible optical cable is easily subject to the impact of extraneous factor (people, environment), easily causes bending radius little, causes the decay of signal; 3. due to what arrange between white heart yearn and the outer coating of optical cable, be that Kev draws material; between have certain gap; therefore; white heart yearn can be movable in coating outside optical cable; in other words; the outer coating of optical cable is contractile with respect to optical fiber, due to inotropic existence, sometimes to the optical fiber protection after being connected and fixed not.
Summary of the invention
Of the present inventionly to solve above-mentioned technical matters; for fiber-to-the-home final stage provides a kind of ready-made, butterfly optical cable jumping fiber that need not field fabrication; it adopts hard optical cable to do line body; during use, wear easy-to-connect, optical fiber does not allow to be subject to the impact of extraneous factor (people, environment) yet, causes bending radius little; main is; hard butterfly sheath is connected with optical fiber closely with blue heart yearn, irremovable each other, more effective to the protection of optical fiber.
For addressing the above problem, the technical scheme that the present invention takes is:
A kind of butterfly optical cable jumping fiber, comprise ceramic insertion core, plastic cement housing, plastic cement inside casing, spring, aluminum riveting part, optical cable and plastic jacket, ceramic insertion core is socketed in plastic cement inside casing, and plastic cement inside casing is socketed plastic cement housing outward, and plastic jacket is socketed in the junction of butterfly optical cable and connector; It is characterized in that, described optical cable adopts single core butterfly optical cable, and the connector that structure is identical is equipped with at the two ends of single core butterfly optical cable; The structure of described connector comprises: ceramic insertion core, metal caudal peduncle, aluminum riveting part, single core butterfly optical cable, wherein, and the structure that single core butterfly optical cable is connected with metal caudal peduncle rear end, the front end of metal caudal peduncle is being socketed
sC(Square Connector, is translated as: foursquare connector) body and the structure being connected with ceramic insertion core rear end (fixing) after spring; Optical fiber and blue heart yearn are through the mesopore of metal caudal peduncle under the wrapping of reinforcement, and optical fiber is connected with ceramic insertion core; At single core butterfly optical cable, with aluminum riveting part, as protectiveness, be fixedly connected with overcoat plastic jacket with the junction of metal caudal peduncle; The interlocking of SC body is in the rear end of plastic cement inside casing, and therefore, the connector consisting of ceramic insertion core, metal caudal peduncle, aluminum riveting part, single core butterfly optical cable is movable with respect to plastic cement inside casing.
Described metal caudal peduncle adopts copper structural member, and handle is provided with two annular projections.On the annular projection of metal caudal peduncle rear end, be socketed with aluminum riveting part, aluminum riveting part overlaps simultaneously catches single core butterfly optical cable, increases the pulling force of single core butterfly optical cable and connector.
On the annular projection of described metal caudal peduncle rear end, be socketed with aluminum riveting part, aluminum riveting part overlaps simultaneously catches single core butterfly optical cable, increases the pulling force of single core butterfly optical cable and connector.
The optical property of butterfly optical cable jumping fiber of the present invention requires:
Insertion loss: the insertion loss of arbitrary connector (plug) (containing adapter)≤0.30d B (containing repeatability);
Return loss: the return loss > 50dB of arbitrary connector (plug).
The good effect of butterfly optical cable jumping fiber of the present invention is:
(1) adopting hard optical cable---single core butterfly optical cable is made connection optical cable, according to single core butterfly optical cable design feature, (optical fiber is embedded in optical cable, can not be freely movable), butterfly optical cable connector connects by adapter, or after moving after ceramic insertion core, more effective to the protection of optical fiber, and in construction, wear easy-to-connect, the impact that is not subject to extraneous factor (people, environment) causes bending, also can not cause the decay of signal;
(2) butterfly sheath is connected with optical fiber closely with blue heart yearn, irremovable each other, the connector consisting of ceramic insertion core, metal caudal peduncle, aluminum riveting part, single core butterfly optical cable is mass activity with respect to plastic cement inside casing, according to single core butterfly optical cable design feature, this protection to optical fiber is more effective;
(3) for fiber-to-the-home final stage provides a kind of ready-made, butterfly optical cable jumping fiber that need not field fabrication, to user, provide larger convenience.
