Embodiment 2

[0050] Such as image 3 As shown, the first lens base 100 and the second lens base 200 include two rows of optical paths, half of each row of optical paths are used as emitting optical path components and half are used as receiving optical path components. The receiving optical path component can receive it. Other specific structures and working principles are the same as those in Embodiment 1.

Embodiment 3

[0052] Such as Figure 4 with Figure 5 As shown, the first lens base 100 includes two emitting light paths, that is, the first light emitter 1 and the second light emitter 12 are located on one side of the first lens base 100, through the transmission in the first lens base 100 and After being reflected, it passes through the multi-channel optical fiber 11 and then enters the second lens base 200 , and finally exits through the second lens base 200 and is received by the first light receiver 13 and the second light receiver 10 . The specific principles of reflection and transmission are the same as those in Embodiment 1, and will not be repeated here.

[0053] Beneficial effects of the present invention: the dual-wavelength multi-channel parallel transmission optical component provided by the present invention includes a light emitting component, a light receiving component and a multi-channel optical fiber, the light transmitting component includes a light transmitter and a...

Abstract

The invention, which belongs to the technical field of optical communication, particularly provides a dual-wavelength multi-channel parallel transmission optical assembly comprising a light emitting assembly, a light receiving assembly and a multi-channel optical fiber. The light emitting assembly includes a light emitter and an emitting lens substrate; and the light receiving assembly includes alight receiver and a receiving lens substrate. The emitting lens substrate and the multi-channel optical fiber are sequentially arranged at an emission light path of the light emitter; and the receiving lens substrate and the light receiver are sequentially arranged at an emergent light path of the multi-channel optical fiber. According to the invention, multi-channel multi-wavelength transmissionis realized; the incident collimating lens array and the receiving collimating lens array can adopt the same array lens; the optical fiber transmission capability is fully utilized; a dual-wavelengthscheme is provided for high-speed parallel transmission products such as a chip on board and an active optical cable; and thus an active coupling packaging scheme as well as passive coupling packaging can be realized.

Description

technical field [0001] The invention belongs to the technical field of optical communication, and in particular relates to a dual-wavelength multi-channel parallel transmission optical component. Background technique [0002] With the rapid growth of services such as the Internet, cloud computing, and big data, the large-scale construction of large-capacity and high-bandwidth data centers is being promoted. In the field of optical communication, single-fiber bidirectional transmission is used to increase the transmission capacity of optical fiber, and parallel multi-channel is used to achieve large capacity. [0003] In practical applications, the existing COB (chip on board) optical components used in 40G SR4, 100G SR4, etc. are all single-wavelength unidirectional transmission, and the laser uses VCSEL (Vertical-Cavity Surface-Emitting Laser, that is, vertical cavity surface-emitting type laser). Although the transmission capacity can be increased by increasing the numbe...
