Embodiment Construction

[0015] see figure 1 , The hardware circuit of the present invention is composed of three parts: an optical relay unit circuit, a photoelectric conversion unit circuit and a power management unit circuit. Introduce respectively below.

[0016] 1. Optical relay unit circuit

[0017] The optical fiber module (Fiber Model, plastic optical fiber module, which collects optical signals) is connected to the optical fiber module for receiving and sending signals. The signal is a differential signal, which is connected by a resistance pull-up and pull-down matching circuit, mainly to complete the voltage matching of the signal. and voltage compensation. The attenuated optical signal coming in from the fiber optic module at one end, after passing through the relay circuit, the signal energy is compensated to its original size, and can be transmitted for a longer distance after going out from the fiber optic module at the other end. Specifically: the optical fiber modules at both ends,...

Abstract

Provided is a photoelectric adapter which comprises a power supply management unit circuit which is used for completing power supply for the overall photoelectric adapter circuit. The photoelectric adapter also comprises an optical relay unit circuit and a photoelectric conversion unit circuit which are connected in turn. The optical relay unit circuit comprises optical fiber modules and a voltage matching compensation circuit which is arranged between the optical fiber modules. The photoelectric conversion unit circuit comprises two coding and decoding chips KS8721 which adopt RMII interfaces. The coding and decoding chips KS8721 have optical and electric interface modes, wherein one chip is arranged to be the optical mode, and the other chip is arranged to be the electric mode so that signal transmission after coding and decoding is completed. A problem of communication distance of plastic optical fibers is effectively solved by an optical relay function completed by the optical relay unit circuit.

Description

Technical field [0001] The invention involves a photoelectric adapter. Background technique [0002] With the continuous development of computer network transmission rates, the application of high rates to desktop is becoming more and more common.Plastic fiber is suitable for connection, and the coupling efficiency of light is also high. At the same time, it also has the advantages of softness, bending, vibration resistance, anti -radiation, cheap price, and convenient construction.Local networks with more connection points. [0003] In order to solve the "last mile" communication solution for plastic optical fiber products to replace glass fiber, a photoelectric adapter will be urgently needed to lead a revolutionary leap in leading communication methods.At present, this photoelectric adapter is very scarce. Invention content [0004] The technical problem to be solved by the present invention is to provide a photoelectric adapter to solve the technical problem of the lack of p...
