The structure of the invention will be explained with reference to the drawings:

as shown in fig. 8-12, the present application mainly exhibits the following features during the design process:

(1) a beam splitter 9. The light splitter 9 is a right triangle, the inclined plane is at an angle of 45 degrees, and the surface is coated with a light splitting film, for example, 98% transmission 2% reflection, or 90% transmission 10% reflection, or other proportion is adopted according to actual needs, and the other two planes are not coated with films.

(2) A first G-lens collimator. A C-lens collimator can be used in a common optical device, and is designed as a G-lens collimator in the patent, so that the optical splitter and the G-lens are conveniently bonded together by using glue to form a whole, and the first G-lens collimator is conveniently coupled with a second G-lens collimator of which the right side is attached with the optical splitter 9.

(3) The light emitting component 6: after the first G-lens collimator and the second G-lens collimator are coupled and debugged to be qualified, the transparent glass tube 601 is sleeved, and glue is respectively dispensed at the left end and the right end for fixation, so that a complete light-emitting assembly 6 is formed. When the optical signal is normally transmitted from the left side or the right side, the optical splitter only reflects 2 percent of light, and the rest 98 percent of light can still be transmitted, so that the loss is small, and the normal use is not influenced. When the maintenance is needed, the red light is introduced from the left side, and 2% of the red light can be reflected and escaped from the upper surface of the optical splitter according to the reflection principle, so that the observation is convenient; when red light is transmitted from the right side, 2% of red light can be reflected and escaped from the lower surface of the light splitter, and observation is facilitated. The optical path is schematically shown below.

(4) A stop seat assembly 3. The light-transmitting jumper SC stopper is specially designed, and the four sides of the light-transmitting jumper SC stopper are provided with through hole structures 10, so that the transparent parts 10 are convenient to install. The movable base covers the light emitting element 6 during the assembly process and is combined with the front conventional SC part. When the red light detection is performed, the light splitter of the light emitting component 6 emits red light, and the red light is emitted from the transparent member 101, so that the function of quickly searching the link can be achieved.

The invention comprehensively considers the use scene of the connector, the light-emitting component 6 is arranged in the connector structure, when the other end of the light-permeable jumper is led with red light, the light-emitting component 6 of the connector can emit the red light, so that the input end, the output end and the whole link can be quickly searched, and the invention is very convenient, time-saving and labor-saving.

The manufacturing process of the application is as follows:

step (1): two G-lens collimators (a first G-lens collimator and a second G-lens collimator) were fabricated. The method comprises the steps of fixing G-lens and an outer layer glass tube (a first glass tube body and a second glass tube body), enabling two G-lens planes to be outside (paying attention to the fact that the two G-lens planes are exposed to be about 2mm in length), inserting single-fiber tail fibers (a first single-fiber tail fiber and a second single-fiber tail fiber) into the outer layer glass tube (the first glass tube body and the second glass tube body) from the other end, adjusting light spots (or loss), and dispensing and fixing after determining. (note: collimator fabrication has a well established fabrication process in the optical device industry.

Step (2): one plane of the beam splitter 9 is attached to a second G-lens collimator 6032, as schematically shown above.

And then coupling and debugging the first G-lens collimator and the second G-lens collimator, sleeving a transparent glass tube 601 after a preset loss value is reached, dispensing and fixing, and finishing the manufacturing of the light-emitting assembly 6.

And (3): and firstly, a tail sleeve and a pressure ring of the SC connector are inserted into the optical cable. The end of the light-emitting component 6 with the optical splitter is welded with the optical fiber, and the other end is directly manufactured into an SC connector: and the optical fiber penetrates into the ferrule, the solidified optical fiber and the ferrule, and the complete light-permeable connector end is obtained through assembly, grinding and end face detection.

The practical use condition is as follows:

as shown in the following schematic view, when installing the connection of the optical patch cord to the machine room or the upper and lower floors, one side employs the conventional patch cord, and the other side employs the light-permeable patch cord to connect thereto, note that the light-permeable SC connector is installed at the middle panel.

When the optical patch cord works normally, the communication wavelength is generally in the optical patch cord, and the display window of the light-permeable patch cord cannot see any special phenomenon.

As shown in fig. 13, when a link is installed or found to be faulty and needs to be repaired, the following schematic diagram is used for connection confirmation:

(1) adopt 5mW red light pen to connect the pen of leading to light from right side 3# SC connector, inspection panel 3# department light-transmitting window can confirm that ruddiness is clear visible, then the 3# wire jumper in right side is normal, observes simultaneously whether the 3# connector in left side sees through ruddiness, if, then the whole wire jumper in left side is also normal.

(2) When a light-transmitting pen is connected from the left 2# SC connector, a light-transmitting window at the 2# position of the panel is checked, and it can be confirmed that red light is clearly visible, the left 2# jumper wire is normal; and simultaneously observing whether the 2# SC connector on the right side transmits red light or not, and if so, enabling the whole jumper on the right side to be normal. If light is transmitted on one side, no red light is observed on the other side or the brightness is very weak, the jumper wire on the side is damaged or broken, and needs to be replaced.

When the service life of the arranged conventional jumper is long and needs to be replaced, the jumper can be replaced and connected one by one in the mode.

In some application scenarios, if only a certain power of light is required to pass through, this can be achieved by using optical splitters with different splitting ratios.
