Description
Technical field
The present invention relates to a kind of optical cable, be specifically related to the implant of a kind of high resistance pressure outdoor optical cable and use thereof.
Background technology
Optical cable is that a number of optical fiber forms the cable heart according to certain way, is surrounded by outward sheath, and the also cladding outer jacket having, in order to realize a kind of communication line of optical signal transmission.Single-mode fiber and multimode fibre it is divided into by the transmission mode of optical fiber.Single-mode fiber refers in operation wavelength, can only transmit the optical fiber of a communication mode, is often referred to simply as single-mode fiber (SMF:SingleModeFiber).At present, in cable television and optic communication, it is most widely used optical fiber.Due to, the fibre core of optical fiber very thin (about 10pm) and refractive index be step-like is distributed, when normalized frequency V parameter < when 2.4, in theory, can be only formed single mode transport.It addition, SMF does not have mode dispersion, not only transmission band is wider compared with multimode fibre, and the addition of the material dispersion and structure dispersion of adding SMF is offset, and its composite character forms the characteristic of zero dispersion just, makes transmission band more widen.In SMF, because the different difference with manufacture of alloy has many types.Umbilicate type cladded-fiber (DePr-essedCladFiber), its covering forms double structure, the covering of contiguous fibre core, and the refractive index of relatively outer ladle-to-ladle layer is also low.It addition, there is matching type cladded-fiber, its cladding index is evenly distributed.Multimode fibre, is called multimode fibre (MMF:MUltiModeFiber) by those length of work with the optical fiber that its propagable pattern is multiple patterns by optical fiber.Core diameter is 50pm, and owing to transmission mode is up to hundreds of, transmission bandwidth is limited mainly by modal dispersion domination compared with SMF.In history once for the short-distance transmission of cable television and communication system.After SMF optical fiber occurs, it appears that history of forming product.But it practice, owing to the MMF core diameter compared with SMF is big and is combined easily with the light source such as LED, in numerous LAN advantageously.So, in short haul connection field, MMF is still coming into one's own again.
Outdoor optical cable is for outdoor optical cable, because needs are suitable for being used in outdoor application, it is therefore necessary to possess some mechanical properties, the environmental characteristics such as durable, pressure, corrosion-resistant, tension.Existing outdoor optical cable can't fully meet user demand.
