The patent No. is that the Chinese utility model patent specification of ZL200820199642.9 discloses the compound cable of a kind of photoelectricity, this recombination line cable wrap is drawn together outside sheath and inner cable core, its cable core comprises optical cable and data cable, optical cable is positioned at the center of cable, data cable is stranded around optical cable, data cable is formed according to certain twisting pitch is stranded by two heart yearns, and each is to the twisting pitch difference of the heart yearn of data cable.But the data cable in the compound cable of this photoelectricity is looped around the optical cable outside and makes that data cable forms side pressure to optical cable in stranded process, cause the macrobend radius of the optical fiber in the optical cable less easily, cause the decay of light signal to increase, thereby influenced the transfer of data of communications optical cable.
The utility model content
The purpose of this utility model is: provide a kind of photoelectric comprehensive digital communication cable, thereby optical cable is subjected to when stranded the side pressure of telecommunication cable to cause the bigger problem of signal transmission attenuation in the prior art to overcome.
The technical solution of the utility model is: a kind of photoelectric comprehensive digital communication cable, mainly form with the cable core that is installed on sheath inside by the sheath of outside, described cable core contains at least one bundle cable and the Capacitance Unbalance in Telecom Cables more than two bundles is right, described cable core also comprises the web frame that extends along the sheath longitudinally, this web frame comprises the dividing plate that cable along the line radially distributes radially more than two, form relatively independent threading district between the inwall of adjacent separator and sheath, described optical cable and each Capacitance Unbalance in Telecom Cables are to corresponding being located in the corresponding threading district respectively.
Described Capacitance Unbalance in Telecom Cables is provided with three beams or two bundles to twisted-pair feeder.
Be provided with 1～4 optical fiber in the described optical cable.
Described optical fiber is provided with hard-pressed bale dry type stop water outward or the bale breaking petroleum jelly is filled stop water.
It is criss-cross cruciform skeleton that described web frame is connected to form the cross section by four dividing plates, forms four independent threading districts between adjacent separator and the jacket inner wall.
The utility model adopts technique scheme, it is separated optical cable and telecommunication cable by web frame, make mutually noninterfere between optical cable and the telecommunication cable, cable is to the side pressure of optical cable when having avoided stranded, both reduced the decay of optical cable signal transmission, improve right cross-talk and the return loss performance of Capacitance Unbalance in Telecom Cables again, also avoided the construction that repeats of network laying simultaneously, reduced the waste of resource.

Embodiment
Embodiment one: as shown in Figure 1, be provided with in the sheath 4 of the photoelectric comprehensive digital communication cable in the present embodiment three beams order wire cable to a bundle cable, wherein, Capacitance Unbalance in Telecom Cables adopts oxygen-free copper bar to make raw material to the conductor 1 in 20, after continuous casting and rolling processing, its molecular structure is arranged closely, have good electric conductivity and mechanical performance, and then make soft round copper conductor by polyphone line wire drawing and annealing, conductor is coated with polyethylene layer 2.; Be provided with a pair of optical fiber 5 in the optical harness 10; for protection optical fiber is not subjected to external action; outside at optical fiber 5 also is coated with stop water; in the present embodiment; skin at each optical fiber 5 coats hard-pressed bale dry type stop water 6 respectively; it can adopt external diameter is that the primary coating fibre of 250 μ m directly constitutes with soft flexible material hard-pressed bale to 900 μ m such as PVC; it can also adopt external diameter is primary coating fibre coating one deck resilient coating of 250 μ m; the resilient coating external diameter is 350-400 μ m; and then hard-pressed bale to 900 μ m, cushioning layer material is materials such as silicones.For guaranteeing the stranding lay configuration rounding of photoelectric comprehensive digital communication cable, and Capacitance Unbalance in Telecom Cables is not to forming side pressure to tightly packaged fiber in the stranded process, avoid causing tightly packaged fiber macrobend radius little, signal attenuation increases, axially being provided with the cross section in sheath 4 is criss- cross web frame 3,4 dividing plates 31 that this cross web frame 3 is radially outwards dispersed radially by the cable center are formed, each dividing plate 31 is connected towards an end at cable center, form four independently threading districts between adjacent separator 31 and the jacket inner wall, optical harness and three beams Capacitance Unbalance in Telecom Cables are to being located in respectively in each self-corresponding independent threading district.
Embodiment two: present embodiment two is with the difference of embodiment one, the optical fiber 5 outside stop waters that coat in the present embodiment are filled stop water for the bale breaking petroleum jelly, it comprises a loose sleeve pipe 7, optical fiber 5 is set in the loose sleeve pipe 7, is filled with petroleum jelly inserts 8 between loose sleeve pipe 7 and optical fiber 5.
Embodiment three: the area that this embodiment is mainly used in not needing the Local Network or the Local Network has been installed.The difference of itself and embodiment one is, only be provided with two bundle Capacitance Unbalance in Telecom Cables in the communications cable to 20, web frame 3 adopts the Y shape structure that is connected to form by three dividing plates 31, form three independently threading districts between the inwall of adjacent separator 31 and sheath 4, a bundle cable 10 and two bundle Capacitance Unbalance in Telecom Cables are located in respectively in each self-corresponding threading district 20.
Photoelectric comprehensive digital communication cable of the present utility model mainly is the Fast Ethernet 100Base-TX communication standard design of adopting at present communication access net, and this standard only uses two pairs of unshielded twisted pairs just can realize user's online demand in actual applications.But for increasing the function of this telecommunication cable, make telecommunication cable can satisfy the demand of online, can also transmit telephone signal simultaneously, make it can a line dual-purpose, reduce circuit and repeat to lay, therefore, in the foregoing description mainly with 3 bundle Capacitance Unbalance in Telecom Cables to being example.
In actual applications, the number of fibers in the foregoing description in the optical cable can be 1～4, and concrete line number is pressed the actual needs setting.
Because the transmission course of signal in cable be decay easily often, cause transmission range to shorten, and the type of conductor and insulation and physical dimension are the principal elements that influences the decay of data symmetrical cable.Therefore main increase insulation thickness and the pair twist pitch of adopting redesigns to reduce decay in the utility model.Cross-talk is an important indicator of circuit transmission quality, and it is the cross-talk that is caused producing voltage and electric current in adjacent lines by electromagnetic field, it with the right pitch of pair twist pitch, laying up pitch and each line than relevant.For guaranteeing that cross-talk meets the requirements under the high frequency, during practical application, 5 classes or surpass 5 class cable for digital communication pair twist group pitches select suitable pitch within 12～22 scopes, 6 class cable for digital communication pair twist group pitches select suitable pitch could obtain preferable decay and near-end crosstalk within 8～18 scopes.
