Abstract
The utility model discloses a side pressure resistant optical cable which comprises an optical fiber, wherein a flat armored elastic tube is arranged outside the optical fiber; a reinforcing layer is arranged outside the armored elastic tube; and an outer sheath is arranged outside the reinforcing layer. By adopting the structure, the side pressure resistance is improved along with reduction of the outer diameter of the armored tube, and the maximum value reaches the extreme value (8000N/10CM) of the conventional optical cable testing equipment at present. The indoor and outdoor optical cables of various specifications processed by the side pressure resistant optical cable are small in size, light in weight and good in environmental suitability and can be widely applied to optical transmission operations under complex environment conditions such as building wiring, key machine room equipment optical connection, field operation, sensing detection, fiber-to-the-home and fiber to the desk.
Description
Technical field
The utility model relates to a kind of cable, particularly a kind of lateral pressure resistant optical cable.
Background technology
Since optical fiber comes out, because the optical fiber self character uses under various environment, must be processed into the optical cable with corresponding mechanical property, guarantee optical fiber is guaranteed the safety used to guarantee the unimpeded of network in the process of laying, install, use, safeguarding.And optical fiber is very weak originally in anti-side pressure and shock resistance aspect.
The utility model content
The purpose of this utility model is, a kind of lateral pressure resistant optical cable is provided.This optical cable can raising itself anti-side pressure and impact resistance, use safer.
The technical solution of the utility model: a kind of lateral pressure resistant optical cable, comprise optical fiber, optical fiber is provided with the flat armouring elastic tubes of one deck outward, and the armouring elastic tubes is provided with enhancement Layer outward, and enhancement Layer is provided with oversheath.
In the aforesaid lateral pressure resistant optical cable, described armouring elastic tubes is spiral fashion.
In the aforesaid lateral pressure resistant optical cable, the described material that shoots solenoid is stainless steel.
In the aforesaid lateral pressure resistant optical cable, the material of described enhancement Layer is aramid yarn.
In the aforesaid lateral pressure resistant optical cable, the material of described oversheath is PBT.
Compared with prior art, the utility model has consisted of a kind of lateral pressure resistant optical cable by optical fiber, armouring elastic tubes, enhancement Layer and oversheath.The utility model adopts such structure, and the lateral pressure resistant ability increases along with reducing of armour pipe external diameter, and maximal value has reached the extreme value (8000N/10CM) of present conventional optical cable testing equipment.And the indoor and outdoor optical cable of all size that is processed into by the utility model, volume is little, lightweight, good environmental adaptability, can be widely used in the light transmission operation under building cabling, the connection of emphasis calculator room equipment light, field work, sensor measuring, fiber entering household, fiber to the desk etc. the complicated environmental condition.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described, but not as the foundation to the utility model restriction.
Embodiment.A kind of lateral pressure resistant optical cable consists of shown in Fig. 1, comprises optical fiber 4, is provided with the flat armouring elastic tubes 3 of one deck outside the optical fiber 4, and the armouring elastic tubes is provided with enhancement Layer 2 outward, and enhancement Layer 2 is provided with oversheath 1.
Armouring elastic tubes 3 is spiral fashion.
The material that shoots solenoid 3 is stainless steel, also can adopt sand blast hose.
The material of enhancement Layer 2 is aramid yarn, and aramid fiber has the special performances such as yarn density is little, and stretch modulus is high, and fracture strength height and fracture elongation are lower; Under higher temperature, can keep intrinsic stability, unusual low-shrinkage, lower creep and very high glass transition temperature, have in addition higher corrosion resistance, non-conductive, except strong acid and highly basic, have stronger anti-chemistry must, be that superior optical cable is strengthened unit material.
The material of oversheath 1 is PBT, and PBT is good fire proofing, has good heat resistance, good corrosion resistance, the characteristics such as electrical specification is good, water absorptivity is little.
