Description
Technical field
The utility model relates to plastic optical fiber installing area, is specifically related to a kind of joints of optical fibre.
Background technology
Silica fibre is as the pioneer of fiber optic communication field, and its installation cost is but high.Silica fibre has overcome the serious problem of traditional communication mode electromagnetic interference (EMI), but install, continues very inconveniently, and cost is very high.Silica fibre quality is crisp, bad mechanical strength, install, continue needs certain instrument, equipment and technology; Core diameter is little, and docking is difficult for, along separate routes, be coupled dumb; The bending radius of optical cable is large, easily damages.These problems that silica fibre exists have not only increased the enforcement difficulty of optical fiber telecommunications system, have also increased system installation and maintenance cost simultaneously.In the case, plastic optical fiber is introduced into fiber optic communication field.
Plastic optical fiber does not have the problem of installation and maintenance difficulty, but the transmission range of SI plastic optical fiber is shorter, can only be for hundred rice grain pattern letters.SI plastic fiber core refractive index is greater than coating refractive index, realizes incident light total reflection occurs at core-Pi interface with this, and the transmission of light in fibre core relies on this total reflection to advance with serrate.Because the incident angle of incident light is different, cause each mould light to arrive the asynchronism(-nization) of receiver, and occur pulse strenching phenomenon.Under the limited condition of broadening, the incident angle of the incident light of SI plastic Optical Fiber Transmission is limited, causes its Bandwidth-Constrained, again because of the existence of dispersion, causes SI plastic optical fiber communication distance to be confined to hundred meters.
GI plastic optical fiber has than the much bigger bandwidth of SI plastic optical fiber, and transmission range is also much larger than SI plastic optical fiber simultaneously.GI plastic optical fiber not only has common plastics optical fiber light weight, softness, insensitive to vibrating, bending radius is large, and pulling strengrth is excellent, durable, it is little to take up room, bandwidth is high, it is insensitive that peer end of the connection face is hidden the dust and the chip that stay, do not produce radiation, is not subject to the impact of electromagnetic interference (EMI) and radio frequency interference and noise completely, safe coefficient is high, data transmission possibility is not ravesdropping, cutting, wiring, bonding, polishing and other handling eases, the feature that installation and maintenance cost is low; And light when transmit in GI plastic optical fiber, refractive index Cong Zhou center to edge reduces gradually, radially being para-curve changes, make each mould light transmission speed therein different, and that their arrive time of receiver is almost identical, output pulse strenching is little, so much bigger than SI plastic optical fiber of GI plastic bandwidth of an optical fiber, long transmission distance, can easily transfer to the above distance of 500m simultaneously.
Continuing of any optical fiber all will complete by the joints of optical fibre.Existing silica fibre interface is various in style, but is not all suitable for plastic optical fiber.No matter being external diameter or core diameter, silica fibre is all less than plastic optical fiber, so silica fibre connector is not suitable for plastic optical fiber.Simultaneously, the core diameter of GI plastic optical fiber and external diameter are less than again SI plastic optical fiber, it is not tight that the GI plastic optical fiber insertion SI plastic joints of optical fibre easily occur that the joints of optical fibre coordinate with optical fiber, the problem of the difficult alignment of luminous point, so the SI plastic joints of optical fibre are not suitable for GI plastic optical fiber yet.

Embodiment
Optical fiber communication have bandwidth, at a high speed, exempt from electromagnetic interference (EMI), radiationless, anti-eavesdrop, the multiple advantage such as safe and reliable.At present optical fiber communication medium has two kinds of silica fibre and plastic optical fibers, and wherein, plastic optical fiber can be divided into again SI plastic optical fiber and GI plastic optical fiber.
Silica fibre luminous point docking precision prescribed is high, needs professional instrument, technology to operate, and meanwhile, silica fibre is very responsive to vibration, high to application environmental requirement.SI plastic Optical Fiber Transmission distance is 100m only, at present can only be for " last hundred meters " engineering of fiber entering household.GI plastic optical fiber has overcome the shortcoming that silica fibre installation and maintenance cost is high and SI plastic Optical Fiber Transmission distance is short simultaneously, is conducive to advance the universal of light net.
The utility model is greater than silica fibre for GI plastic fibre diameter and is less than again common plastics optical fiber, and the problem that can not be used in conjunction with existing fiber connector, a kind of FC plastic joints of optical fibre of the GI of being applicable to plastic optical fiber are provided, have been conducive to advance the universal of GI plastic optical fiber.
The FC plastic joints of optical fibre provided by the utility model; as shown in Figure 1; comprise becket 31, sleeve 32, connector 33, lock pin 34, tin hat 35 and tail pipe 36; lock pin 34 runs through connector 33 centers; for optical fiber, insert; connector 33 top layer band metal rotation cover locking structures, can combine closely with interface simultaneously, the location while also having guaranteed to be connected with interface simultaneously.Lock pin 34 is hollow-core construction, by metal or plastics, is made, and external diameter is 2.5mm, can support the use with standard interface.Lock pin diameter of bore is 1.0mm, and GI plastic fiber outer layer diameter is 0.5mm, and the two is suitable in conjunction with degree of tightness, GI plastic optical fiber is easy to insert lock pin endoporus,, applies in the situation of external force meanwhile, also plastic optical fiber can be extracted out from lock pin, be used in conjunction with other connectors.
This FC plastic joints of optical fibre assembling mode is as follows:
With scissors intercepting, need the plastic optical fiber of length, use optical fiber cutter cutting optical fibre, obtain smooth end face;
