As shown in fig. 2, 3, and 4, the fiber optic cartridge tester 100 of the present disclosure includes a detector 120 and a light source module 140.
The light source module 140 includes a plurality of light sources 142 and is disposed opposite the detector 120, wherein the fiber optic cartridge 200 may be disposed between the detector 120 and the light source module 140 during testing.
According to an embodiment of the present disclosure, the fiber optic cassette 200 includes an integrated end 201 having one or more fiber optic connection interfaces and a fan-out end 202 having one or more fiber optic connection interfaces. By way of non-limiting example, fiber optic cassette 200 may comprise, for example, a fiber optic cassette such as MPO-LC/SC, such that one end of fiber optic cassette 200 may be an integrated end having an MPO fiber optic connection interface and the other end may be a fan-out end having an LC or SC fiber optic connection interface. However, in other embodiments, the fiber optic cartridge 200 may include any type of optical cartridge suitable for placement between the light source module 140 and the detector 120 for optical detection, and is not limited to the above-mentioned examples.
As shown in fig. 2 and 3, the detector 120 is disposed at the integrated end 201 of the fiber optic cartridge 200 and the light source module 140 is disposed at the fan-out end 202 of the fiber optic cartridge 200. According to some embodiments of the present disclosure, the detector 120 and the light source module 140 are arranged at a distance from the fiber optic connection interfaces at both ends of the fiber optic cassette 200, i.e., the detector 120 and the light source module 140 are free of any physical contact with the fiber optic connection interfaces at both ends of the fiber optic cassette 200. However, in other embodiments, it is also possible that the detector 120 and the light source module 140 are arranged in contact with the fiber optic connection interfaces at both ends of the fiber optic cassette 200.
In order to allow the light source module 140 to better couple light to the fiber optic connection interface of the fan-out end 202 of the fiber optic cassette 200. The light source module 140 can include a plurality of light sources 142 forming an array, and the plurality of light sources 142 are arranged such that each light source 142 can be aligned with each fiber optic connection interface at the fan-out end 202 of the fiber optic cassette 200, whereby optical incidence can be achieved from each light source 142 to each fiber optic connection interface at the fan-out end 202 of the fiber optic cassette 200. The alignment of each light source 142 with each fiber optic connection interface at the fan-out end 202 of the fiber optic cassette 200 as described above is advantageous in that it allows the light sources 142 to emit light to each fiber optic connection interface in a non-interfering manner, thereby enabling non-interfering transmission of each fiber optic pathway within the fiber optic cassette.
The fiber optic cartridge tester 100 may also include a frame 110 such that the detector 120 and the light source module 140 can be arranged in a relatively fixed manner on the frame 110. As a non-limiting example, as shown in fig. 2 and 3, the detector 120 is disposed at an upper side of the frame 110, and the light source module 140 is disposed at a lower side of the frame 110. However, in other embodiments, the detector 120 and the light source module 140 can be arranged on the frame 110 in other manners.
In some embodiments of the present disclosure, the frame 110 may further include a slideway 111 thereon. Thus, the detector 120 can slide on the frame 110 along the slide 111 in a first direction, which may be parallel to the end face of the integrated end 201 of the cartridge 200. This enables the detector 120 to slide to different fiber optic connection interfaces of the end face of the integrated end 201 of the cartridge 200 in order to receive light exiting from the different fiber optic connection interfaces. As shown in FIG. 2, the end face of the integrated end 201 of the fiber optic cassette 200 shows two fiber optic connection interfaces, but in other embodiments, the end face of the integrated end 201 of the fiber optic cassette 200 may have more or fewer fiber optic connection interfaces depending on the particular type of fiber optic cassette 200.
The frame 110 may further include a holder 160 thereon, and the holder 160 may be used to hold the fiber cartridge 200 above the light source module 140 and below the detector. In particular, the retainer 160 keeps the detector 120 and the light source module 140 from any physical contact with the fiber optic connection interfaces at both ends of the fiber optic cassette 200.
Furthermore, the fiber optic cassette tester of the present disclosure may also preferably include a controller configured to sequentially drive the plurality of light sources in the light source module 140 to emit light towards the plurality of fiber optic connection interfaces at the fan-out end of the fiber optic cassette. At the same time, a detector 120 is disposed at the integrated end 201 of the cartridge 200 to detect light coupled in from the fan-out end 202. The detection of the continuity of the plurality of fiber paths within the cartridge 200 and the polarity of the fiber optic connection interface may be accomplished using the detection of the output light at the integrated end 201 of the cartridge 200 by the detector 120.
According to a preferred embodiment of the present disclosure, the controller may be further connected to the frame 110 and the detector 120, thereby enabling automatic control of the sliding of the detector 120 and the detection. In a preferred embodiment of the present disclosure, the detector 120 may include a CCD.
The testing process of the fiber optic cassette tester of the present disclosure is briefly described as follows:
during testing, first, the fiber optic cassette 200 is disposed between the detector 120 and the light source module 140 comprising the plurality of light sources 142, wherein each light source 142 of the plurality of light sources 142 is alignable with each fiber optic connection interface of the plurality of fiber optic connection interfaces at the fan-out end 202 of the fiber optic cassette 200; then, light is emitted from the plurality of light sources 142 to the plurality of fiber optic connection interfaces in the fan-out end of the fiber optic cassette 200; and detecting light at the integrated end of the cartridge 200. In particular, the plurality of light sources in the light source module 140 may be sequentially driven to emit light toward the plurality of fiber optic connection interfaces at the fan-out end, thereby further improving the detection efficiency of the fiber optic cassette 200.
The fiber optic cassette tester and the testing method thereof of the present disclosure have been described above in detail. Through the optical fiber card box tester and the test method thereof, optical detection of the optical fiber card box can be realized without plugging and unplugging jumper wires, so that the test efficiency of the optical card box is greatly improved. Test experiments show that: with the fiber optic cassette tester of the present disclosure, it is possible to test fiber optic cassettes at least 4 times faster than conventional methods of testing fiber optic cassettes.
In addition, because the optical fiber cassette tester disclosed by the invention does not need to use jumper connection for optical test, the non-contact optical test of the optical fiber cassette becomes possible, thereby avoiding the scratch and/or pollution of the inserting core of the optical fiber interface of the optical fiber cassette, and ensuring that the optical test can not cause any influence on the quality of the optical fiber cassette. In addition, due to the method of contactless optical testing, it is possible to achieve the desired optical testing of the fiber optic cassette even without the dust cap of the fiber optic cassette being removed.
Embodiments of the fiber optic cassette tester and method of testing the same of the present disclosure have been described above in detail. Various modifications to the described embodiments can be understood and effected by those skilled in the art in practicing the claimed invention, from a study of the drawings, the disclosure, and the appended claims. It is to be understood that, unless indicated to the contrary, in any methods defined herein as including more than one step or action, the order of the steps or actions of the method is not necessarily limited to the order of the steps or actions of the method recited. In the claims, the word "comprising" does not exclude other elements or steps, and the indefinite article "a" or "an" does not exclude a plurality. The mere fact that certain measures are recited in mutually different dependent claims does not indicate that a combination of these measures cannot be used to advantage. Reference signs in the claims shall not be construed as limiting the scope.
