Abstract

The invention discloses a parallel optical structure double receiving and double transmitting box seal packaging optical device comprising a box seal tube shell having a multilayer ceramic circuit. Afirst flexible circuit board and a second flexible circuit board are electrically connected on the circuit of the multilayer ceramic circuit outside the box seal tube shell. The box seal tube shell isinternally provided with a first laser, a second laser, a first photodiode, a second photodiode, a first trans-impedance amplifier, a second trans-impedance amplifier, a reflecting mirror, a first filter, a second filter, a third filter, a fourth filter, a first collimating lens, a second collimating lens, a first focusing lens and a second focusing lens. The outer side of the third filter insidethe box seal tube shell is provided with a common end lens. The position, which is close to the common end lens, of the outside of the box seal tube shell is provided with an optical fiber insertingcore sleeve component. The degree of integration of the optical device can be enhanced, the volume can be reduced, the packaging process can be further simplified and the coupling efficiency of the device can be enhanced.

Description

technical field [0001] The invention relates to a double-emitting and double-receiving device for single-mode optical fiber data transmission, which is applied in the technical field of optical communication. Background technique [0002] With the development of data centers, passive optical network fiber-to-the-home and wireless data transmission networks, the hermetic packaging of miniaturized integrated optical transceivers is in great demand in the application of short-distance single-mode optical fiber wavelength division multiplexing data transmission. The existing multi-channel optical device sealing and packaging method uses a single optical device to be sealed and packaged one by one, and then performs wavelength division multiplexing; or uses all lasers to be sealed and packaged in an optical emitting device, and all photodiodes are sealed and packaged in an optical receiving device, and then wavelength division multiplexing is performed. Multiplexing. Due to the ...
