Description
Technical field
The present invention relates to a kind of joints of optical fibre and joints of optical fibre group, particularly have the joints of optical fibre and the joints of optical fibre group of three optical fiber.It has the simple and big characteristics of use elasticity of using method.
Background technology
The joints of optical fibre are indispensable in the communication system of any utilization optical fiber significant components.For instance, the joints of optical fibre can be used to arrange in pairs or groups optical fiber reaching longer length, and then optical fiber is connected to as aggressive devices such as transceiver, detecting device and repeaters, or optical fiber is connected to as passive devices such as switch and attenuators.One of Core Feature of the joints of optical fibre is in order to keep or to locate two optical fiber, causing the fibre core (core) of an optical fiber axially to calibrate with the fibre core of another optical fiber.In addition, another Core Feature of the joints of optical fibre is can be with light and the calibration fiber that optical transmitting set sent.Therefore, the light that is transmitted can be coupled in the optical fiber efficiently.This is a challenging especially task, and (that is fibre core) is quite little because the light of optical fiber carries the zone.In single mode (single mode) optical fiber, about 9 microns of core diameter.In multimode (multi-mode) optical fiber, its fibre core can be as big as 62.5 to 100 microns.Therefore, accurate calibration is the necessary link that optical fiber is connect mutually.
Another function of the joints of optical fibre provides mechanical stability and the protection of optics intersection (optical junction) at its working environment.In general, the stable and protection of intersection is the function (for example, reducing the influence of different heat expansion and mechanical motion) that the design connector must be considered.The accurate calibration of optical fiber is normally finished among the design of optic terminal assembly (optical terminus assembly).Typical optic terminal assembly adopt a kind of terminal is remained in the connector and with the method for its integration, and the method that adopts a kind of clamping and fiber optic calibration.For fiber optic calibration, its terminal can comprise a metal or ceramic small column usually, generally is called " lasso " (ferrule).Lasso has high-precision hole by its center line, makes that glass or plastic optical fiber can be by machinery, that stick together or other reservation method with in the holes that is mounted to lasso.
Connection between a pair of optical fiber is with a pair of lasso two end ons together, and light can be passed to another optical fiber along common central shaft by optical fiber wherein.In traditional optics connects, expect that very the fibre core of glass fibre can be calibrated accurately, to reduce the light loss (that is so-called insertion loss) that is caused by connecting as far as possible.But well known, also can not make one at present and perfectly connect.Manufacturing tolerance may can be near 0, but actual Consideration (for example cost) makes slight deviation to tolerate.In other words, though stable operating environment is vital for the connection of optical fiber, and non-essential.
On history, because manufacturing cost and design feature, optic terminal often manufactures the assembly with loose assembly.In the high performance connectors that single mode is used, need to adjust the eccentric phenomena of assembly.This adjustment can realize by the interaction between terminal or ferrule supports structure and the connector shell.If connector shell is a conformability assembly, then when optic terminal shifts out from connector shell (for example, because factors such as cleaning or replacings) adjusts the effect that just lost.
The fine setting of optic terminal assembly normally is used for reducing the arbitrary position of optical fiber in optical conenctor inside.Arbitrary position may be in the grade of hundreds of nanometers to several microns.Yet, be optical waveguide (optical waveguide) diameter when having only 8 to 9 microns single-mode fiber when what consider, under the situation of not retentive control fibre core, it will be appreciated that the insertion loss of highly significant.The optical fiber eccentricity compensation is common on the single passage Lucent Connector at present.Compensation is to utilize end face (facet) structure (for example, square or sexangle) to be indicated in the front end of ferrule supports structure and realize.The ferrule supports structure can suitably complementally be connected with the LC connector, and remaines in the LC connector.Therefore, adjustment or optical fiber eccentricity compensation just are retained in the ferrule supports structure in the connector.In case remove, just can not determine the definite position relation between optical fiber clamp structure and the connector.
Summary of the invention
