Optical communication transceiver and application thereof

Abstract

The invention discloses an optical communication transceiver comprising an optical communication transmit-receive component and an optical fiber transmitting optical signals. The optical communication transmit-receive component comprises a shell and a BOSA (optical transmit-receive integrated component) and a PCBA which are arranged in the shell. The optical communication transceiver is characterized in that the BOSA is arranged on the upper part of the PCBA, and the transmitting end and the receiving end of the BOSA are electrically connected with the PCBA. The shell is provided with an optical fiber interface used for inserting of the optical fiber. One end of the optical fiber is provided with an optical fiber connector. The optical fiber connector is connected with the optical fiber interface in a sealing way, and the inserting core of the optical fiber connector is connected with the optical interface of the BOSA in a contact way. The lower part of the PCBA is provided with a connector used for being connected with external equipment. With application of the technical scheme, the optical communication transceiver has the beneficial effects that the optical communication transceiver has the advantages of high degree of integration, small size, great waterproof performance and EMI / EMC performance and fast transmission rate so as to be particularly suitable for the automobile and other environments of severe application conditions.

Description

technical field [0001] The invention relates to the field of optical communication, in particular to an optical communication transceiver and its application. Background technique [0002] Traditional automotive electrical control systems use electrical wires made of metal such as copper as the conduction and connection of control signals. For example, in a car with a central control computer, in order to precisely control various peripheral components of the car, such as engine, transmission system, braking system, suspension, door frame, power distribution, anti-theft, airbag, reversing, entertainment and navigation, etc., it is necessary to A large number of electrical wires made of metal are connected to the central control computer and the drive lines of peripheral components to transmit various electrical control signals so that each peripheral component can work normally. [0003] However, with the rapid development of the automobile industry, the traditional automob...

AI Technical Summary

Problems solved by technology

[0003] However, with the rapid development of the automobile industry, the traditional automobile electrical system with wire harnesses as the main connection method has the following shortcomings in actual operation, mainly in the following aspects: (1) With the increase in the number of data communications between electronic control units Increase, the high-speed data transmission rate becomes very important, the transmission rate of ordinary wire harness can no longer meet the transmission of high-speed data

(2) Metal wires are easy to oxidize and corrode, which leads to an increase in line impedance, affects the correct transmission or connection of electrical signals, and easily leads to short circuit or spontaneous combustion, thus posing safety hazards

[0004] The above-mentioned shortcomings can be overcome by using optical fiber network, but the existing optical transceiver modules are mainly used for commercial or industrial grades. Due to the harsher application environment in the automotive field, the waterproof, size, EMI / EMC performance of optical transceiver modules, etc. Put forward higher requirements, resulting in the existing optical transceiver module can not meet the requirements

In addition, with the rapid development of the automotive industry, the requirements for data transmission rates are getting higher and higher. The transmission rate of traditional automotive-grade optical modules is still below 1G, which cannot meet the requirements of the rapid development of the automotive industry.
