Title:
PARALLEL TRANSMISSION AND RECEPTION OPTICAL MODULE FOR DUAL-LINK TRANSMISSION, AND PREPARATION METHOD
Document Type and Number:
WIPO Patent Application WO/2017/118271
Kind Code:
A1
Abstract:
A parallel transmission and reception optical module for dual-link transmission, and a preparation method. The transmission and reception optical module comprises a transmission optical device (103), a reception optical module (104), a PCB circuit board (102), and a data interface. The transmission optical device (103) consists of a first contact pin collimator (201) and a first tube assembly (202). The first contact pin collimator (201) comprises a first optical fiber interface (401), a single-mode contact pin (402), and a first collimation lens (403), all of which are sequentially coupled and fixed to the first contact pin collimator (201). The first tube assembly (202) comprises a wavelength division multiplexing assembly (405), a coupling lens group (406), and a laser chipset (407), all of which are sequentially coupled and fixed to the tube assembly. The reception optical module (104) consists of a second contact pin collimator (204) and a second tube assembly (205). The second contact pin collimator (204) comprises a second optical fiber interface (501), a multi-mode contact pin (502) and a second collimation lens (503), all of which are sequentially coupled and fixed on the second contact pin collimator (204). The second tube assembly (205) comprises a wavelength division demultiplexing assembly (504), an array lens (505) and a detector chipset (506), all of which are sequentially coupled and fixed to the tube assembly. The optical module has capabilities of transmission on a long-distance single-mode optical fiber and a short-distance multi-mode optical fiber, and has the characteristics of low costs, batch production and miniaturization. Also provided is a preparation method for the optical module.
