Abstract
The utility model provides an optoisolator with a bracket, which comprises two symmetrical collimators and an optical core which is arranged between the two collimators. The optical core comprises two symmetrical birefringence optical wedges and a Faraday rotator which is arranged between the two symmetrical birefringence optical wedges. The utility model is characterized in that a first bracket and a second bracket are respectively arranged at the peripheries of the two birefringence optical wedges which are respectively attached to and fixedly connected with the first bracket and the second bracket, the Faraday rotator is fixedly arranged in the first bracket and the first bracket and the second bracket can rotate relatively. The utility model has the beneficial effects that the assembly is convenient, the relative angle and position of the two birefringence optical wedges and the Faraday rotator can be adjusted for obtaining the best isolation.
Description
Technical field
The utility model relates to a kind of isolator, relates to a kind of optoisolator of belt supporting frame particularly.
Background technology
In recent years, the optical fiber communication development is very fast, uses day by day extensive.Optical fiber communication element such as coupler/splitter, optoisolator etc. as the important component part of optical fiber communication equipment have progressively formed industrial scale.In the optical fiber telecommunications system of two-forty, require lasing light emitter highly stable, for this reason, wish to reduce as far as possible the reflected light that laser instrument is got back in load.The performance of optoisolator just light positive to very little by time decay, but oppositely by the time decay very big device, provide reliable solution for addressing the above problem.
Existing optoisolator comprises incident optical, first collimating apparatus, optoisolator core, second collimating apparatus and outgoing optical fiber successively along the light path direction of propagation, the optoisolator core is made up of a pair of symmetrically arranged birefringent wedge and the Faraday rotator between two birefringent wedges, existing optoisolator can be realized the forward low-loss propagation of light, the effect that backlight is isolated, but exist be easy to generate chromatic dispersion, the light isolation is low and problem such as difficult adjusting.
The utility model content
The utility model provides a kind of optoisolator of belt supporting frame for addressing the above problem.
The utility model realizes that the technical scheme that goal of the invention adopts is, a kind of optoisolator of belt supporting frame, comprise symmetrically arranged two collimating apparatuss, and be arranged at two light cores between the collimating apparatus, described smooth core comprises a pair of symmetrically arranged birefringent wedge and the Faraday rotator between two birefringent wedges, it is characterized in that: described two birefringent wedge peripheries are respectively arranged with first support and second support, described two birefringent wedges post and fix with second support with described first support respectively and are connected, described Faraday rotator is fixedly installed in described first support, and described first support can rotate relatively with second support.
Better, described support is the hollow circuit cylinder bodily form.
Better, fixedly connected by the mode of some glue with second support with described first support in the edge of described two birefringent wedges.
The beneficial effects of the utility model are, and are easy to assembly, can regulate the relative angle and the position of two birefringent wedges and Faraday rotator, to obtain best isolation.
