Abstract
The utility model relates to a photoelectric composite communication cable. The photoelectric composite communication cable is composed of an outer surface layer structure and a photoelectric composite cable core, wherein the photoelectric composite cable core is formed by an electric cable and an optical cable. The utility model also provides two technologies of electric transmission and optical transmission. The photoelectric composite communication cable is advantaged in strong adaptability, expandability, low cost for customer purchase, low construction cost and low cost of network construction. On condition that the cost of an original bandwidth access medium of a communication line is constant, an FTTB broadband access mode and an FTTN local telephone twisted-pair access mode can be satisfied. At the same time, when the bandwidth is to be upgraded to the FTTH access mode, only a user terminal needs upgrade so that the FTTH access mode can be realized without a need to change a line, thereby, avoiding waste of resources; and therefore, with the photoelectric composite communication cable, significant economic benefits and social benefits can be achieved.
Description
Technical field
The utility model relates to a kind of photoelectricity composite communication cable.
Background technology
Broadband services is as the emphasis of communications industry fixed network development; The main common carrier of domestic 3 families continues to increase investment on line arrangement; The broadband access pattern is main with FTTB (FTTB) and FTTH (Fiber to the home) mainly; Use last 100 meters product performance based on two kinds of network line access modules, satisfy YD/T1019-2001 and YD/T1997-2009 technical standard.
The exploitation of photoelectricity composite communication cable is the basis with electrical transmission technology and optical transport technology; With light signal and the compound design object that is transmitted as of the signal of telecommunication; With the structural design is research emphasis; Design copper conductor diameter, insulation thickness, twisting pitch have improved the right performance index such as cross-talk, decay, characteristic impedance and return loss of Capacitance Unbalance in Telecom Cables; Select fiber type reasonable in design and manufacturing process to satisfy the circuit optical transmission performance, realization telecommunication and optical communication while also deposit or use separately, satisfy the needs of circuit upgrading.
Application number is that 201020507633 Chinese patent file " optoelectronic composite cable " provides a kind of optoelectronic composite cable scheme, but its optical cable is in the cable center place, makes to be difficult for.
The utility model content
The purpose of the utility model provides a kind of photoelectricity composite communication cable, can realize that telecommunication and optical communication are simultaneously and deposit or use separately and satisfy the needs of circuit upgrading.
For realizing above-mentioned purpose; The scheme of the utility model is: a kind of photoelectricity composite communication cable; Be made up of extexine structure and optoelectronic composite cable core, said optoelectronic composite cable core is made up of cable and optical cable, and said cable is made up of first, second two pairs of unshielded twisted pairs; Said optical cable is a butterfly optical cable, and first, second two pairs of unshielded twisted pairs are distributed in said butterfly optical cable both sides; The single line of the single line of said first pair of unshielded twisted pair and second pair of unshielded twisted pair near; Other single line of the in addition single line of first pair of unshielded twisted pair and second pair of unshielded twisted pair away from; And folder is established the central concave place of said butterfly optical cable between them, and said first, second two pairs of unshielded twisted pairs surround reinforcement one side of said butterfly optical cable.
Said extexine structure is the PVC sheath.
The utility model provides photoelectricity two kinds of transmission technologys simultaneously, and adaptability is high, extensibility is strong, and the family purchase cost is low; Operating expenses is low; The networking expense is low, under the constant situation of the former bandwidth access medium of communication line cost, satisfies FTTB broadband access pattern and FTTN local telephone network twisted-pair feeder and inserts; When bandwidth upgrading is to the FTTH access module in the future simultaneously, only need just can realize the FTTH access module, need not to change circuit, avoid the wasting of resources, have remarkable economic efficiency and social benefit in the user terminal upgrading.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further detailed explanation.
Photoelectricity composite communication cable as shown in Figure 1; Constitute by extexine structure and optoelectronic composite cable core; The extexine structure is a PVC sheath 1, and the optoelectronic composite cable core is made up of cable and optical cable, and cable is made up of first pair of unshielded twisted pair 2 and second pair of unshielded twisted pair 3; Optical cable is a butterfly optical cable 4; The single line of the single line of first pair of unshielded twisted pair 2 and second pair of unshielded twisted pair 3 presss from both sides the central concave place that establishes butterfly optical cable 4 in addition near the single line in addition of, first pair of unshielded twisted pair 2 and second pair of unshielded twisted pair 3 between the single line, the reinforcement of butterfly optical cable 4 one sides partly is between first, second two pairs of unshielded twisted pairs.First, second two pairs of unshielded twisted pairs do not carry out stranded.
Two pairs of unshielded twisted pairs constitute digital communication unit, and butterfly optical cable constitutes optical communication element, and two pairs of 0.5mm data wires of the stranded employing of cable core and GJXH 2 B1.3 specification butterfly optical cables are flat to be dragged, and forms cable core, extrudes one deck LSZH protective cover material.Adopt two twisted pair wire groups, can satisfy voice transfer and transfer of data simultaneously, and twisted pair wire is carried out rational pitch.
