New Description: [New Technology Field] This creation is about a photoelectric connection device, especially a direct-coupled photoelectric connection device for photoelectric conversion and photoelectric connection by direct coupling with an optical fiber. [Prior Art] " Traditionally, an optoelectronic connector provides fiber coupling into an electronic circuit, and the optical signal enables the optical signal to be converted into an electrical signal through a photoelectric conversion unit disposed in the optical connector. The electronic circuit for the back end performs subsequent electrical signal processing, and at the same time, the electrical signal is also converted into an optical signal through the electro-optical conversion unit, so as to achieve communication between the electro-optical and the optoelectronic. However, as in the optical connector 2 shown in FIG. 1, the optical connector 2 is used to couple the external optical fiber 4, and the optical repair symbol LS transmitted in the optical fiber 4 is disposed through the device. The inclined surface 6 provides the optical signal LS for secondary optical conversion (for example, using a beam splitter) to change the optical path. However, those skilled in the art should be aware that if the optical signal LS is converted by secondary optics, optical loss of light reflection, diffraction, and diffusion will occur, causing the optical signal LS to be in the light. The receiving end 8 generates an error 'affecting an increase in the bit error rate (BER). In addition, the structure of the optical connector 2 is such that when the optical signal LS of the optical fiber 4 is aligned with the light receiving end 8, since the conversion of the inclined surface 6 is required, a lot of difficulty is added to the correction alignment. . 3 M416093 The author of this book proposes a direct-type optoelectronic connection device that can be used to solve the lack of conventional techniques.

For the above purposes, the present invention provides a direct-type optoelectronic connector with a complex field for converting optical signals into electrical signals, including a substrate, an optical connection unit, a communication unit, and an electrical connection unit.

In one embodiment of the present invention, the optical connector unit is a connector of the type of angled physical contact. Compared with the prior art, the direct photoelectric connection device of the present invention is directly coupled to the optical fiber via the optical connection unit, and the optical signal transmitted in the optical fiber can be low in coupling loss (for example, light scattering, light diffusion).

The substrate 12 is provided to "and the optical connection unit 14, the communication unit 16 and the electrical connection unit 18, for example, the substrate 12 can be a semiconductor substrate or a printed circuit substrate. The optical connecting unit 14 is disposed on the substrate 12, and the optical connecting unit 14 is used to connect the optical fibers 4. The optical connection unit can be an Enterprise System Connector, a Ferrule Connector, a Fiber Distributed Data Interface Connector, and a local connector (Local). Connector), Subscriber Connector, Straight Tip Connector or Multi-Fiber Push On Connector. Alternatively, in order to avoid reflection of light, the optical connecting unit 14 described above may be further provided with a connector of an angled physical contact type. Here, the optical connecting unit 14 having the plurality of trenches 142 is taken as an example M416093. The trenches 142 directly provide the optical fibers 4 to be disposed in the optical connecting unit 14. In addition, the trenches 142 can be disposed on the substrate 12 in addition to the optical fibers 4, and the communication unit 16 can be effectively aligned by the trenches. In other words, the communication unit 16 is disposed at the same level as the optical connection unit 14 to reduce the incidence of incidence and exit. In addition, the trench 142 can be of any shape, and the s 冓 and 142 are exemplified by an inverted ν type trench, such that the optical fibers 4 and the tether are placed at the bottom of the V-shaped trench, such as the fourth. As shown in the figure, the fourth figure is a schematic diagram showing the structure of the 第_Β in Fig. 2 . Furthermore, in the present embodiment, the trenches 142 are described by taking four trenches as an example. In this embodiment, the trench 142 is used for two channels for the channel of the light money LS input, and the other two channels are used for setting the channel for the output of the optical signal LS. The communication unit 16 has a light detector 162 and an optical transmitter, and the communication unit 16 is disposed on the substrate 12 and at the edge end a of the optical connection unit 14. Here, the communication unit is disposed vertically on the § earth plate 12 for allowing the optical detector 162 and the optical transmitter 164 to directly receive the optical signals LS from the optical fibers 4. In other words, the optical signal LS can be directly incident into the optical detector 162 without optical conversion of secondary optical elements (such as lenses and beamsplitters) (eg, reverse:: refraction, diffraction, and The electric signal ES is converted into an optical signal LS via the communication unit & 16, and is incident on the optical fiber 4 disposed on the optical connection unit 4 by the communication unit 16.

Further, the optical detector 162 and the optical transmitter 164 form a light input and output configuration having η xm. Here, the η and m are integers. Here, the number of the optical detector 162 and the optical transmitter 164 may correspond to the number of the optical fibers 4, respectively. In another embodiment, the optical detector 162 and the optical transmitter 164' can be configured to provide optical signals LS having different wavelengths incident on the optical detector 162 at different positions. However, the number of optical detectors 162 and the optical transmitter 164 is not for the number of confined channels.
