Description
Technical field
The utility model relates to field fiber, particularly relates to a kind of single-mode fiber.
Background technology
Along with development and the active demand of people to long distance, large information capacity communication of the development of Fibre Optical Communication Technology, particularly laser technique, people have searched out again better Fibre Optical Communication Technology-single mode fiber communications.Fibre Optical Communication Technology develops into today, the multimode optical fiber intrinsic a lot of limitation of communicating by letter more loom large: (1), multimode luminescent device are light emitting diode (LED), optical frequency spectrum width, light wave are impure, light transmission dispersion is large, transmission range is little, 1000M bit/s bandwidth for transmission, reliable distance is 255m, 100M bit/s bandwidth for transmission, reliable distance is 2km; (2), because of the intrinsic limitation of multimode luminescent device and the restriction of the existing optical characteristics of multimode optical fiber, the bandwidth of multimode optical fiber communication is 1000M bit/s to the maximum, single mode fiber communications has broken through the limitation of multimode optical fiber communication.
But, the maximum problem that now single-mode fiber exists be optical fiber node mainly with and tortuous wiring more, therefore general single mode fiber bending loss is large, counter-bending drain performance is poor, comprehensive mechanical performance machinery is poor.
Utility model content
The technical matters that the utility model mainly solves is to provide a kind of single-mode fiber, and counter-bending drain performance is good, and compact conformation also has good comprehensive mechanical performance.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of single-mode fiber is provided, comprise: central core, the first counter-bending loss sheath, metal strengthening core, cable core, the second counter-bending loss sheath and surrounding layer, described central core is coated with the first described counter-bending loss sheath, the first described counter-bending loss sheath is outside equipped with described metal strengthening core, described metal strengthening core is outside equipped with described cable core, and described cable core is coated with the second described counter-bending loss sheath and surrounding layer outward successively.
In preferred embodiment of the utility model, the first described counter-bending loss sheath is embossing steel band bonding PE sheath.
In preferred embodiment of the utility model, the second described counter-bending loss sheath is the vertical covering of two-sided chromium plating plastic-coated steel band.
In preferred embodiment of the utility model, the core diameter of described central core is 8 ~ 10 μ m.
In preferred embodiment of the utility model, the thickness of the first described counter-bending loss sheath is 10 ~ 15 μ m.
In preferred embodiment of the utility model, the thickness of the second described counter-bending loss sheath is 15 ~ 25 μ m.
The beneficial effects of the utility model are: the counter-bending drain performance of the utility model is good, and compact conformation also has good comprehensive mechanical performance.
