Hereinafter, various embodiments of the present invention will be described in detail with reference to the accompanying drawings and accompanying drawings, but the present invention is not limited to or limited by the embodiments.

2 is a diagram illustrating a configuration of an apparatus for supporting optical signal measurement and a ferrule scoping according to an embodiment of the present invention.

2, an apparatus 200 for supporting optical signal measurement and ferruoscopy according to an exemplary embodiment of the present invention includes an optical input port 201, an optical meter 209, a ferrule tester 207, a concentrator 203, And a light output port 205. Here, the optical input port 201, the concentrator 203, the optical output port 205, and the ferrule checker 207 are connected to each other by a single scoping And an optical module 211.

The optical input port 101 may be composed of, for example, a plastic (or metal) optical receptacle or a glass rod optical receptacle, and may receive the optical signal emitted from the optical connector 213 to be measured .

When the plastic optical receptacle is connected to the ferrule of the optical connector 213 to be measured, the plastic optical receptacle may be formed so that the gap with respect to the optical connector 213 is less than the set interval, and may be tightly connected to the optical connector 213 . When the plastic optical receptacle is connected to the optical connector 213 using the structure, the position of the optical connector 213 with respect to the ferrule is fixed, and when the cross section of the optical connector 213 with respect to the ferrule has an inclined plane Also, the problem caused by the conversion of the light path can be solved.

Specifically, the plastic (or metal) optical receptacle may be formed of plastic (or metal) and may be formed to include a structure for connecting in a certain direction (e.g., a depression inserted into the protrusion of the optical connector) have. When the plastic optical receptacle and the optical connector 213 are connected to each other and the optical connector 213 includes a protruding portion serving as a reference for the direction, one side of the plastic optical receptacle is the structure including a depression corresponding to the protruding portion , So that the projection is inserted into the depression.

In addition, the glass rod optical receptacle can fix the ferrule of the optical connector 213 to be measured by using a rod of a transparent material (for example, glass).

Specifically, the glass rod optical receptacle may be formed to include a sleeve for fixing the ferrule of the optical connector to be connected and a transparent rod for restricting the movement of the sleeve. At this time, since the glass rod optical receptacle includes a rod made of a transparent material, it is possible to overcome the limitation that the cross section of the optical connector 213 to the ferrule can not be seen through a general ferrule (not a conventional ferrule) can do.

The rod of transparent material in the glass rod optical receptacle may be formed to have the same inclined surface as that of the ferrule of the optical connector 213 when the section of the optical connector 213 with respect to the ferrule has an inclined surface. When the glass rod optical receptacle is connected to the optical connector 213, the inclined surface of the glass rod optical receptacle with respect to the rod of transparent material may be in contact with the inclined surface of the optical connector 213 with respect to the ferrule.

Since the glass rod optical receptacle and the ferrule of the optical connector 213 are always connected in a constant direction as the inclined surface with respect to the rod of transparent material in the glass rod optical receptacle and the inclined surface with respect to the ferrule of the optical connector face each other, It is possible to solve the problem caused by optical path conversion even when the position of the optical connector 213 with respect to the ferrule is fixed and the cross section of the optical connector 213 with respect to the ferrule has an inclined plane.

The optical measuring instrument 209 can receive optical signals transmitted from the optical connector 213 and transmitted through the optical input port 201 connected to the optical input port 201 to measure information about the optical signals.

Here, the second optical signal may be generated and oscillated by the ferrule tester 209, and may be oscillated using a part of the first optical signal reflected or transmitted by the concentrator 203 according to the embodiment, can do.

At this time, when the optical input port 201 is composed of an optical receptacle having a rod of transparent material (that is, a glass rod optical receptacle), the ferrule tester 207 may be configured so that the transparent receptacle Sectional image of the ferrule of the optical connector 213 can be taken and provided through a rod (for example, a cylinder), and based on the taken sectional image, whether or not the optical connector 213 is contaminated with ferrule As such, it is possible to perform the scoping. At this time, the ferrule tester 207 compares the photographed image with a set reference image, and determines whether or not the optical connector 213 is contaminated with the ferrule based on the comparison result (for example, difference degree) , It is possible to easily recognize whether or not the ferrule is contaminated. As another example, the ferrule tester 207 can determine whether or not the optical connector 213 is contaminated with the ferrule by analyzing the sectional image based on the set data information.

The optical output port 205 may be composed of, for example, an optical receptacle with a general ferrule or a fiber pigtail.

As a result, the optical signal measurement and ferrule scoping supporting apparatus 200 receives the optical signal outputted from the optical connector 213 and scans the ferrule of the optical connector 213 with the measurement of information on the optical signal , Optical wavelength, optical power measurement, and ferrule scoping functions are performed at the same time with one connection, thereby making it possible to collectively process work related to optical wavelength, optical power measurement, and ferrule scoping.

The ferrule tester 303 can photograph an image of the ferrule of the optical connector 307 and display it. At this time, the ferrule tester 303 can take images of at least one of the end face of the optical connector 307 to the ferrule, the core in the ferrule, and the clad area. The ferrule tester 303 may determine whether the ferrule is contaminated based on the photographed image and the set reference image.

The optical output port 305 may be composed of, for example, an optical receptacle with a general ferrule or a fiber pigtail.
