Abstract
The utility model discloses a flange type fixation fiber attenuator suitable for a fiber communication system, a fiber sensor, a test apparatus, and a fiber CATV. Attenuation pads (9) are disposed at the bottoms of two inner ends of a seat body (1), a fixed socket (3) is fixed at the inner end of the seat body (1), and is movably connected to the attenuation pads (9). An arc plug (7) of a movable inserting block (2) is movably inserted into the fixed socket (3) via a positioning groove (4) at the right end of the seat body (1). Since an air gap is used to achieve light attenuation, the gap size can be determined by the thickness of a prefabricated attenuation pad, optical power attenuation can be adjusted to a required level, and expensive attenuation fibers are not needed. Flange type connection and fixation are designed, fixed connection is stable. A modular plugging mode is used, and therefore, operation is convenient, connection among components is reliable, plugging loss is low, repeated plugging performance is good, stability is good, size is small, cost is low, service lifetime is long, and fiber attenuation precision is high.
Description
Technical field: the utility model relates to a kind of flange form fixed fiber attenuator that Fiber Optical Communication System, Fibre Optical Sensor, testing tool and Optical CATV are used that is applicable to.
Background technology: along with the extensive of optical fiber popularized, optic fiber converter is also used widely.In the transmission channel of light, need, with attenuator, the signal intensity of receiving is reduced to needed degree, the method of using at present is more generally in optical fibre channel, to access one section of attenuating fiber, to consume or to attenuate part power input in signal transmission, and remainder can continue by this system; Although this method is simple, attenuating fiber needs to add impurity element during fabrication, and production cost is higher, and reliability and stability are poor.
Utility model content: the purpose of this utility model is to provide a kind of decay that realizes light with air-gap, and the damping capacity of light can preset, does not need to consume expensive attenuating fiber.Adopt modularization inserting mode, insertion loss is little, and optical fiber attenuation is accurate, can reduce the flange form fixed fiber attenuator of optical signal transmission loss.
The technical scheme that the utility model taked is for achieving the above object: its attenuation gasket 9 is arranged on 1 liang of inner bottom of pedestal, fixed socket 3 is fastened on pedestal 1 the inner, and be flexibly connected with attenuation gasket 9, the circular arc plug 7 of movable inserted block 2 is plugged in fixed socket 3 by locating slot 4 activities of pedestal 1 right-hand member.
The beneficial effects of the utility model are: owing to adopting air-gap to realize the decay of light, this gap length can be determined with prefabricated attenuation gasket thickness, optical power attenuation can be adjusted to needed level, does not need to consume expensive attenuating fiber.Design flange form and be connected and fixed, be fixedly connected with stablely, utilized modularization inserting mode, easy to operate, between member, connect reliably, insertion loss is little, repeats plug property good, and stable type is good, cheap, long service life, optical fiber attenuation precision is high.And volume is little, lightweight, easy for installation.
Accompanying drawing explanation: Fig. 1 is the utility model structural representation
Fig. 2 is the left view of Fig. 1
Embodiment: as shown in Figure 1 and Figure 2, its attenuation gasket 9 is arranged on 1 liang of inner bottom of pedestal, fixed socket 3 is fastened on pedestal 1 the inner, and is flexibly connected with attenuation gasket 9, and the circular arc plug 7 of movable inserted block 2 is plugged in fixed socket 3 by locating slot 4 activities of pedestal 1 right-hand member.
