Description
Technical field
The present invention relates to the optoelectrical cable of a kind of transmitting optical signal simultaneously and electric power, particularly a kind of as the electric power between the network equipment and the user terminal, the optoelectrical cable of digital signal duplicate transmissions.
Background technology
3G (Third Generation) Moblie technology (being commonly referred to as 3G network) has various ways such as can handling image, music, video, and the function of webpage visit, videoconference, electronic commerce information service etc. is provided.Present situation is, is connected often still to adopt at 3G network equipment and transmission between the user terminal cable of transferring electric power and the optical cable of transmission of digital signals are laid, insert respectively the connection mode in the system separately respectively.Yet, owing to have a plurality of base stations in the 3G network, adopt one of obvious deficiency that above-mentioned connection mode shows, circuit numerous and complicated, laid down cost height, have multihead management and manage and protect difficulty big (concerned power by power office manage, transfer of data manages by commmunication company), the probability that causes various faults is higher relatively; Two, can not embody multi-purpose and cause the wasting of resources, cost to increase.
The applicant retrieved before the technical scheme of oneself is released, in document especially Chinese patent literature, detected much about not only have optical communication, but also the light harvesting, electrical transmission that have the transmission of electricity function concurrently in the following technical information of a cable.
Chinese patent Granted publication CN2435750 discloses a kind of comprehensive leading in cable, it combines in a cable with optical fiber, transmission pressure, signal transmssion line, has contribution to remedying aforesaid 2 deficiencies, but as if too having paid attention to the pursuit multi-purpose has ignored following technical problem owing to it: at first, and because of it is preferably 2 pairs and 4 pairs to transmission pressure and signal transmission wire, thereby cause the interior circuit of cable numerous and complicated, be difficult to identification, optical fiber is as the same, brings puzzlement for continuing when using; Secondly, the single base station that the optical cable of this structure can only be suitable in the 3G communication network uses, and can't be fit to the environmental requirement of the required many power lines of big capacity in many base stations in the 3G communication network.Perhaps think, as long as organically corresponding transmission pressure is aided with colour code in order to differentiation, and in cable core again according to needing to increase transmission pressure, use the many base stations that just can satisfy in the 3G communication network.But in the manufacturing process of reality, this structure arrangement can cause the unreasonable increase of the external diameter of optical cable, thereby also can bring the increase of the material that is located at the outer waterstop of cable core, embossing steel band, outer jacket etc. in regular turn; Also have, the optical cable of this structure is poor because of disturbing property, both has been difficult to moulding, makes troubles to construction again.
The comprehensive leading in cable of the central tubular that CN2548170Y disclosed also exists except the deficiency of being deposited with tool CN2435750: because of optical fiber directly being placed the stainless steel sleeve pipe, cause cable core difficult forming, softness poor, be difficult for out stripping, and because of a little less than the bend resistance performance when the bending stainless steel sleeve pipe easy to crack; Transmission pressure is directly contained by the PE oversheath, and separation difficulty not only, and can't discern for a long time when lead is given and installed and the investigation during the fault generation causes difficulty in the differentiation.
CN2554778Y has disclosed the photoelectromotive force combine rope, though provided the enlightenment of distinguishing cord and soft fiber with different colours, but the photoelectromotive force combine rope of this structure does not belong to the application category of aforesaid binomial patent, even after by means of aforementioned binomial patent structure, it is satisfied to the purposes identical with aforementioned patent, the shortcoming that can similarly expose aforementioned patent so and deposited, only be to distinguish cord, soft fiber is gained ground.
Again, CN2689262Y has provided central beam tube type power supply optical cable, this patent has objectively been pointed out Chinese patent CN2548170Y, CN2308949Y, CN1163414A and the shortcoming that CN2543750Y deposited, concrete structure is: with optical fiber in the centering tube bank and that filled by filler, the cable core that water blocking layer, steel band constituted in the beam tube of center outside is entreated among being arranged at outer jacket in order, has the transmission pressure of the color of different Gong identification differentiations respectively in the outer layout of the steel band of cable core.Technical contribution be moulding easily, softness, lateral pressure resistant intensity height, open stripping convenient, transmission pressure is easy to distinguish, recognize.But also have following deficiency: the one, the arrangement of transmission pressure in outer jacket requires harshness, harsh to the processing request of the mould that is used to produce; Two because transmission pressure is arranged in the oversheath, thereby require oversheath that enough thickness need be arranged, cause the material use amount to increase; Three, to the protective ratio of transmission pressure fragile (it is outer to be positioned at steel band), transmission pressure is short of by extraneous pressure, easily causes the cable distortion, transmission pressure exposes, has potential safety hazard; Four, be not suitable for the field and lay, the limitation of being used is bigger; Five, be not suitable for the required big capacity in many base stations in the 3G communication network, many power supplys, big current-carrying requirement equally.
And, the optoelectronic composite cable that CN2708456Y is related, this is the special submerged cable of a kind of purposes, if it is diverted to single base station in the 3G communication network, then is extremely uneconomic.Equally, if by the applicant in to CN2435750Y, commented like that, satisfy a plurality of base stations in the 3G communication network to increase corresponding cable core, so also will expose identical problem.
Also, though Chinese patent Granted publication CN2548171Y, CN2713490Y, CN2660657Y all disclose the optical cable technology information that has transmitting optical signal, the signal of telecommunication concurrently, therefrom also can't obtain they are transform as and be applicable to that the 3G communication network should have the technology enlightenment of requirement.
Explore and find through the applicant, preferably should possess following key element as the electric power between 3G communication network device and the user terminal, digital data transmission optical cable: one, in an optical cable, be equipped with a plurality of photoelectricity transmissions unit, though each photoelectricity transmission unit structure is in form gathered in a cable as a wholely, yet substantially be again independently separately, use avoid injuring all, all loosing of loosing; Two, each photoelectricity transmission unit can easily be identified, and should satisfy the photoelectricity transmission requirement of single base station; Three, flexibility good, lay conveniently, wiring opens stripping easily; Four, embody maximum economized on the whole to the external protective material of oversheath, armour, inner sheath, water blocking layer and so on.Yet the applicant thinks that top mentioned arbitrary patented technology scheme all can not satisfy the degree of aforementioned key element.
