Description

BACKGROUND OF THE DISCLOSURETechnical FieldThis disclosure relates to an Internet outlet, and more particularly to an Internet outlet with input signal compensation.Description of the Prior ArtAn Internet cable includes eight wires twisted into four pairs of wires. The first pair of cores is white-orange and orange, the second is white-green and green, the third is white-blue and blue, and the fourth is white-brown and brown. The cores are arranged according to the Internet Regulation of the line location T568A or T568B. For example, the arrangement of 1 to 8 according to the conduction position T568B is white-orange, orange, white-green, blue, white-blue, green, white-brown and brown.The line arrangement indicates that the third and the sixth line are connected to the same pair of wires (green and white-green), while the fourth and the fifth line are connected to the same pair of wires (blue and white-blue). The arrangement is not sequential. This generally leads to interference between the wires, which is caused by the two above-mentioned wire pairs, the so-called crosstalk.In an Internet socket module, the gold pins are also arranged from 1 to 8 to correspond to the 1-8 sequence. This also leads to crosstalk disturbances in the signal transmission. In the prior art, various methods for eliminating crosstalk noise can be applied, for example, compensating the gold pins by specially shaping the rear ends of the gold pins or improving the capacitive coupling to avoid crosstalk.Alternatively, a compensation circuit may be added to the circuit board to prevent crosstalk. To avoid crosstalk, a small compensation board may be added.Another design is a double layer arrangement of gold pins. The gold pins are divided into front and rear areas. The gold pins in the front area are connected to the compensation structure, which in the rear area is connected to the main board. A double-layer structure (two parts) is formed between the gold pins in the front and rear regions. When the plug is inserted, the gold pins in the front portion are pressed down by the plug and contact the gold pins in the rear portion of the double-layer structure. In the plug-to-socket signal transmission, the signals are transmitted to the mother board and compensated by the compensation structure connected to the gold pins in the front area, thereby reducing the crosstalk between the gold pins.Another gold pin design includes main and compensation gold pins. The main gold pins are connected to a motherboard and project forward with their free ends. Each compensation gold pin has a compensation end and a support end. The compensation gold pins are arranged below the main gold pins and correspond to the respective main gold pin. The support ends abut the main gold pins, thus providing a support force. Capacitive couplings are formed at the compensation ends, so that when the plug is inserted, the transmitted signals are compensated for against crosstalk by the compensation structure of the compensation end of the compensation gold pin.Although the additional board for compensation can effectively improve the properties of the Internet socket, it also leads to an increase in costs.In view of the foregoing, the inventor has studied the related technology to solve the above-mentioned drawback and has provided a reasonable and effective solution in this disclosure.SUMMARY OF THE INVENTIONThe disclosure relates to a photonic integrated circuit and a corresponding test method with which the intensity, line width and linearity of the laser light can be checked.This disclosure relates to an Internet outlet with input signal compensation.

A gap between the embedded segment 231 of the third data receiving port 230 and the embedded segment 251 of the fifth bilateral communication port 250 has a second width 102. A gap between the embedded segment 251 of the fifth bilateral communication terminal 250 and the embedded segment 271 of the seventh bilateral communication terminal 270 has a third width 103. The first width 101 is greater than the second width 102, and the first width 101 is less than the third width 103.Specifically, in the first terminal group 201, the embedded segment 231 of the third data receiving terminal 230 and the embedded segment 251 of the fifth bilateral communication terminal 250 have longitudinal edges that protrude laterally from each other, and a gap having the second width 102 is defined therebetween.

At the longitudinal edge of the third data receiving terminal 230, a recessed notch corresponding to the contour of the insulating seat 100 for embedding is formed.FIG. 7 is a perspective view showing the arrangement of the terminals in the second terminal group of the Internet outlet according to an embodiment of this disclosure. Referring to FIGS. 5 and 7, the second terminal group 202 is disposed on the positioning block 110 on the second side 112. Specifically, in the second terminal group 202, the embedded segments ( 221, 241, 261, 281) of the second data supply terminal 220, the fourth bilateral communication terminal 240, the sixth data reception terminal 260, and the eighth bilateral communication terminal 280 are respectively embedded in the positioning block 110 on the second side 112, and the embedded segments ( 221, 241, 261, 281) are embedded in the positioning block 110 within the embedded region 104, as illustrated in FIG. 7.Referring to FIG. 7, a gap between the embedded segment 221 of the second data supply port 220 and the embedded segment 241 of the fourth bilateral communication port 240 is defined with a third width 103, a gap between the embedded segment 241 of the fourth bilateral communication port 240 and the embedded segment 261 of the sixth data reception port 260 is defined with a second width 102, a gap between the embedded segment 261 of the sixth data reception port 260 and the embedded segment 281 of the eighth bilateral communication port 280 has a portion defined with the first width 101 and another portion defined with the second width 102.Specifically, in the second terminal group 202, the embedded segment 241 of the fourth bilateral communication terminal 240 and the embedded segment 261 of the sixth data receiving terminal 260 have longitudinal edges that protrude laterally from each other, and a gap having the second width 102 is defined therebetween.

At the longitudinal edge of the sixth data receiving terminal 260, a recessed notch corresponding to a contour of the positioning block 110 for embedding is formed.Referring to FIGS. 6 and 7, it should be appreciated that a broad embedded segment may result in an increase in self-inductance and mutual inductance. The adjacent side edges of the fourth bilateral communication terminal 240 and the sixth data receiving terminal 260, and the adjacent side edges of the third data receiving terminal 230 and the fifth bilateral communication terminal 250 are straight. Thereby, the effective coupling length between a line pair connected to the third data receiving terminal 230 and the sixth data receiving terminal 260 and a line pair connected to the fourth bilateral communication terminal 240 and the fifth bilateral communication terminal 250 can be extended to improve the compensation.At a part of the side edge of the embedded segment 231 of the third data receiving terminal 230 adjacent to the side edge of the embedded segment 211 of the first data providing terminal 210, there is a recess for reducing the coupling compensation between the first data providing terminal 210 and the third data receiving terminal 230.

In addition, a corresponding compensation circuit is mounted on the printed circuit board 300.Recesses are respectively disposed at the outer edges of the central portions of the embedded segments ( 211, 281) of the first communication terminal 210 and the eighth bilateral communication terminal 280 to increase inductance and provide support via a shape corresponding to the switch of the insulation seat 100.FIG. 8 is a cross-sectional view along the longitudinal direction of a terminal of the first terminal group of the Internet outlet according to an embodiment of the disclosure.
