Abstract

The utility model discloses a fiber cable which includes an outer protective sleeve, a warping tape and a central reinforcer; the fiber cable also includes a plurality of strands of fibers and a plurality of five target cables in the warping tape; the fiber includes a fiber protective sleeve layer, an aramid fiber layer, a cushion layer and a core layer in sequence from outside to inside; the outermost layer of the five target cables is a five target cable protective sleeve the inside of which comprises twin twisted single cables; each strand of single cable includes an insulating layer and a copper wire layer in sequence from outside to the inside. The fiber cable provided by the utility model has the advantages of reasonable design, compact structure, easy manufacture, low cost, light weight and good flexibility. During actual use, the loss of the fiber is lower as the fiber is transmitted by light; moreover, the interference of electromagnetic signals can be avoided; however, as the joint part of the fiber is easily damaged, the joint of the fiber is troublesome to be replaced during actual use; in the fiber cable, when the fiber is damaged, the five target twin twisted cables are used to replace the fiber for signal transmission, which can achieve redundancy.

Description

A kind of Connectorized fiber optic cabling

Technical field

The utility model relates to a kind of Connectorized fiber optic cabling, particularly relates to a kind of Category-5 twisted pair that comprises, and just with the transmission of Category-5 twisted pair substitution signal, can accomplish redundant Connectorized fiber optic cabling when optical fiber damages.

Background technology

Along with the development of intelligent comprehensive wiring, the effective bandwidth that data cable provided can not satisfy the demand of high-end user.Along with EPON EPOU technology is day by day ripe, the FTTH line construction will be widely used in the intensive business premises of user distribution, residential quarters and industrial park, and it has the ability of Triple-Play (triple play) such as carrying high speed Internet access, VolP, IPTV and TDM business.Transmission medium is an optical cable in the FTTH line construction, comprises feeder line optical cable, optical distribution cable, register one's residence optical cable and workspace wire jumper.

At present, Chang Yong multicore horizontal wiring cable configuration is that optical fiber and non-metal reinforcement member bunchy loosely are in the cable outer sheath center.The optical cable core number of this structure is big, in light weight, but the optical fiber in the cable core is easily free stranded, and ordering is chaotic, and beam split inserts when indoor, looks for fine trouble, and dish is fine irregular; And because structure is not compact, quite a few concentrates on the oversheath to bear tension force, and the effect of non-metal reinforcement member holding capacity is limited.

Its every interior optical fiber of vertical wirings branched cable commonly used has independently nonmetal reinforcing element and protective sleeve, and every optical fiber energy individual branches is convenient to install identification.But the branched cable cost is higher, and the cable footpath is thicker relatively, and the core number is difficult for increasing.General 12 cores of core number now commonly used insert when indoor owing to be single fiber, also need use wavelength-division multiplex technique and relevant equipment, cause the optical fiber cost of registering one's residence to heighten.In addition, also have the big ribbon fiber optical cable of a kind of core number to make distribution usefulness, but fine trouble of the time-division of continuing, dish is fine uneven, and it is difficult to safeguard.Therefore, when rational and effective is utilized conduit resource, require external diameter little to feeder line optical cable and optical distribution cable, it is high that the density of optic fibre in the cable is wanted; The optical cable of registering one's residence is also pliable and tough, and can bear certain pulling force and pressure, possesses better mechanical property.

The utility model content

At the problems referred to above, fundamental purpose of the present utility model is to provide a kind of Category-5 twisted pair that comprises, when optical fiber damages,, can accomplish redundant Connectorized fiber optic cabling, compare with common Connectorized fiber optic cabling just with the transmission of Category-5 twisted pair substitution signal, the Connectorized fiber optic cabling that the utility model provides is reasonable in design, compact conformation, easy to manufacture, cost is low, in light weight, pliability is good.

The utility model solves above-mentioned technical matters by following technical proposals: a kind of Connectorized fiber optic cabling, this Connectorized fiber optic cabling comprises oversheath, twining package tape and central reinforce member, it is characterized in that: described Connectorized fiber optic cabling also comprises some strands of optical fiber and some to category-5 cable that wrap in the twining package tape, described optical fiber is followed successively by fiber jacket, aramid layers, cushion, fiber core layer from outside to inside, the outermost layer of described category-5 cable is the category-5 cable sheath, described category-5 cable sheath includes two strands of single lines of multiple twin, and per share single line is followed successively by insulation course, copper wire layer from outside to inside.

Wherein, described central reinforce member is a gasket for packing.

Wherein, described category-5 cable has two pairs.

Wherein, the thickness range of described oversheath is: 0.8-1.2mm.

Wherein, the thickness range of described cushion is: 0.7-1.1mm.

Positive progressive effect of the present utility model is: the Connectorized fiber optic cabling that the utility model provides has the following advantages: reasonable in design, and compact conformation, easy to manufacture, cost is low, and is in light weight, and pliability is good.Because the joint of optical fiber is damaged easily, when damaging,, can accomplish redundancy just with the transmission of Category-5 twisted pair substitution signal.

Embodiment

Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to describe the technical solution of the utility model in detail.Fig. 1 is the utility model structural representation, and as shown in Figure 1, this Connectorized fiber optic cabling comprises oversheath 100, twining package tape 200 and central reinforce member 300, and described cable also comprises two strands of optical fiber 400 and the two pairs of category-5 cables 500 that wrap in the twining package tape 200.Described optical fiber 400 is followed successively by fiber jacket 401, aramid layers 402, cushion 403 and fiber core layer 404 from outside to inside, as shown in Figure 3.The outermost layer of described category-5 cable 500 is a category-5 cable sheath 501, and described category-5 cable sheath 501 includes two strands of single lines of multiple twin, and per share single line is followed successively by insulation course 502 and copper wire layer 503 from outside to inside, as shown in Figure 2.In the actual manufacture process, central reinforce member 300 is generally gasket for packing, category-5 cable among the present invention has two pairs, is twisted-pair feeder in twos, also can increase logarithm according to actual needs, the thickness range of oversheath 100 is: 0.8-1.2mm, be preferably 1mm, the thickness range of cushion 403 is: 0.7-1.1mm is preferably 0.9mm, the raw material that cushion 403 adopts is a Polyvinylchloride, and the raw material that fiber jacket 401 and oversheath 100 adopt also is a Polyvinylchloride.

In actual use, optical fiber is because be light transmission, the loss ratio of optical fiber is lower, and can avoid the interference of electromagnetic signal, but because the joint of optical fiber is damaged easily, in actual the use, the joint of optical fiber is changed cumbersome, when optical fiber damages, just transmit among the present invention, can accomplish redundancy with the Category-5 twisted pair substitution signal.
