Optical signal transmitting-receiving module and light path controlling method thereof

Abstract

The present invention mainly comprises light signal transceiving component and circuit board. The optical fibre connection end disposed via one side of the light signal transceiving component is connected with optical fibre, a filtering plate is utilized to generate deffection for light signal issued by the optical fibre for it being into input end then the light signal is converted to be electric signal transmitted to the circuit board through photoelectric converting unit. With the same principle as above, the electric signal can be converted to be the light signal which is transmitted to the optical fibre so action of transmitting and receiving light signal can be selected at the same time by setting on optical fibre at an optical connection end.

Description

technical field [0001] The invention relates to an optical signal transceiver module and an optical path control method thereof, which are applied to receive and transmit optical signals, in particular to an optical signal transceiver module integrating output and input optical signals and an optical path control method thereof. Background technique [0002] The prosperity of the optoelectronic industry in recent years has improved the quality of life of the general public. The application of optical fiber networks and the development of leisure home appliances are attributed to the efforts of related research units and industries in optoelectronic communication. Among them, the conversion and transmission of light energy signal and electronic signal play a pivotal role. The optical transceiver module is installed in the electronic device, so that the electronic device can receive or transmit optical signal through optical fiber. Please refer to figure 1 , is a perspective ...

Problems solved by technology

[0003] As can be seen from the above, the known design uses the receiver 13 and the transmitter 14 to perform receiving and transmitting operations respectively, and divides the circuit board into two blocks to prevent cross talk and improve transmission efficiency. quality; but the receiving and transmitting actions must be handled separately, the space required is large, and the production cost is also increased; moreover, the distance between the two circuit boards is very close to reduce the size, so not only the assembly is difficult, but also the product development Testing and correcting actions are often thus limited
