The present invention takes rational twisting pitch to subelement;
The twisting pitch of subelement of the present invention is 10CM～100CM;
The present invention adds carbon black in outer jacket 06.
The quantity of subelement of the present invention is 2～4, each subelement can be single core cable 07 or filler cells 08, that is to say, subelement can be single core cable 07 all, can be filler cells 08 all, also can be made of jointly single core cable 07 and filler cells 08, for example, optical cable has 4 subelements, and wherein 2 subelements are single core cables 07, and other 2 subelements are filler cells 08.
The problem that has solved the optical cable for connection of present no chamber inside/outside light device of the present invention, well solve present common outdoor optical cable and be unsuitable for indoor use, the general room optical cable can not be used for outdoor contradiction, have that transmission capacity is big, speed is fast, good confidentiality, flexible, fire-retardant, lightning protection, plurality of advantages such as light, is the dual-purpose optical cable of building at the 3G optical-fiber network of a kind of chamber inside/outside.Adopt optical cable of the present invention, can directly connect two equipment during construction, the equipment room outdoor section carries out according to the construction method of outdoor optical cable fully.
The beneficial effect that obtains:
1, the present chamber inside/outside optical cable of having determined needs the problem of welding conversion;
2, the light device that directly connects two chamber inside/outsides;
3, need not earthing device, optical cable itself prevents the introducing of thunder and lightning.
Description of drawings
Fig. 1 is the optical cable schematic cross-section of the preferred embodiment of the present invention.
Embodiment
With reference to Fig. 1, single-core fiber 01 is placed in the central authorities of tight sleeve layer 02, and tight sleeve layer 02 is placed in reinforcement 04 central authorities, it outside reinforcement 04 subelement sheath 03, take this to constitute single core cable 07, filler cells 08 comprises reinforcement 04 and subelement sheath 03, and 4 subelements 07 are placed outer jacket 06.Can also between subelement and outer jacket 06, reinforcement 05 be set.As previously mentioned, tight sleeve layer 02 material is a flame-proof polyvinyl chloride, and structure is circular, can be good at protecting single-core fiber 01, can also adopt polyester material to improve heat resistance when specific (special) requirements is arranged; The reinforcing material 04 and 05 that adopts is an aramid yarn, has very high modulus, can well improve tensile strength, protects optical fiber, and can not cause the conduction of thunder and lightning; Outer jacket 06 and subelement sheath 03 material adopt the low-smoke non-halogen flame-retardant tygon, and flame is propagated along optical cable when effectively having solved burning, can not produce poisonous flue gas simultaneously; Outer jacket 06 is a black, and has dosed carbon black, can effectively absorb ultraviolet ray, and the protection optical cable is injury-free.Simultaneously, subelement is taked rational twisting pitch, this twisting pitch can be 10CM～100CM.In addition,, guarantee the serviceable life of optical cable, in outer jacket 06, dose carbon black in order effectively to absorb ultraviolet ray.
