Description
Technical field
the utility model relates to electronic technology field, especially relates to a kind of safe optical cable.
Background technology
along with social development, it is more and more important that communication becomes.In prior art, the bandwidth of wireless telecommunications and frequency are all at full stretch, so the stable means of communication of this large bandwidth of optical cable is still the most reliable mode of data transmission.
in prior art, in a lot of situations, need by optical cable installation in the wild, the part optical cable need to through forest with the attached extension of electric pole.Because there is oil optical cable inside, squirrel likes best and bites, easily produce the phenomenon of freezing the optical cable winter on high mountain in addition, the ice layer thickness diameter can reach 5-10CM, when the bear load of weight over optical cable that freeze, optical cable just easily is pressed down, and causes down bar or communicating interrupt, and communication section is caused to heavy losses.
existing rodent-resistant cable adopts chemical agent, and its shortcoming has pollution to environment, optical cable maintenance personnel and processing staff, water source, and can't carry out antifreezely, is specially:
(1). optical fiber is water funk, be afraid of that the ice light wave transmits in optical fiber, along with gaining in strength of transmission range weakened gradually, is called fibre loss.The reason that loss produces mainly is divided into: absorption loss and the large class of scattering loss two.In absorption loss, have hydroxyl to absorb, mainly just refer to the loss that outside moisture produces optical fiber, therefore from the characteristics of optical fiber: optical fiber be water funk, be afraid of ice.
(2). temperature variation makes optical fiber produce microbend, causes fibre loss to increase:
most of material of optical cable is plastics, the characteristic of plastics is easily to be acted upon by temperature changes. what temperature variation had the greatest impact to optical fiber is exactly loss characteristic, it will make the loss of optical fiber increase, fibre core and covering are all the all-glass fibers of glass, under high and low temperature, working loss all can increase, and the attenuation increase of particularly working at low temperatures is more remarkable.The reason that temperature variation increases attenuation is that optical fiber is subject to the effect of axial compressive force and produces microbend, and fibre loss is increased.Axial compressive force is to cause because plastics are different with quartzy linear expansion coefficient, quartzy linear expansion coefficient is 3 * 10-7/ ℃, and silicon rubber and nylon are 1 * 10-4/ ℃, the every variation of temperature once, length variations amount quartzy and plastic coating differs approximately 1000 times, that is to say the quartzy 1mm of contraction, plastic coating shrinks 1m.In this case, optical fiber will produce microbend.
The utility model content
for the unreasonable optical cable that is laid in field that causes of current cable configuration, be easy to suffer muroid invasion and attack, nature extreme climate to affect, thereby cause the problem that the Cable's Fault rate is high, a purpose of the present utility model is to provide a kind of simple and reasonable safe optical cable.
in order to realize this purpose, the utility model provides a kind of safe optical cable, comprises power supply, alternating current-direct current times pressure controller, DC temperature relay, optical cable insulating overcoat, heating tape; Wherein said optical cable insulating overcoat is socketed in outside Cable Core, and described optical cable insulating puts outward and is provided with along the axially extended banded heating tape of described optical cable insulating overcoat, described heating tape one end connects described alternating current-direct current times pressure controller, but the connector that the other end connects by folding connects DC temperature relay, and described alternating current-direct current times pressure controller also connects described power supply.
as technique scheme preferably, described power supply comprises solar panel, alternating current-direct current inverter controller, accumulator; Described solar panel all is connected described alternating current-direct current inverter controller with accumulator, and described alternating current-direct current inverter controller connects described alternating current-direct current times pressure controller.
as technique scheme preferably, a described alternating current-direct current times pressure controller is connected with remote-receiver.
as technique scheme preferably, described safe optical cable also comprises temperature measuring mechanism, described temperature measuring mechanism connects described alternating current-direct current times pressure controller and DC temperature relay.
the beneficial effects of the utility model are: the utility model proposes a kind of safe optical cable, can be powered by sun power, and produce heat by heating tape and carry out the snow melt ice-melt.Simultaneously can also be the optical cable insulating overcoat outside generation current in case the stop thing encroach on.
The accompanying drawing explanation
by below in conjunction with accompanying drawing to a description that preferred embodiment carries out of the present utility model, it is clearer that the technical solution of the utility model and technique effect thereof will become, and easy to understand more.Wherein:
