Title:
OPTICAL MODULE
Document Type and Number:
WIPO Patent Application WO/2021/109645
Kind Code:
A1
Abstract:
An optical module (200), comprising: a circuit board (300), an optical transmitter (301), an optical detector (302), an optical receiver (303), a lens assembly (400), and an optical fibre strip (500); the optical fibre string (500) is connected to the lens assembly (400); a first recessed part (401) and a second recessed part (402) are arranged on the top surface of the lens assembly (400), the bottom surface of the lens assembly (400) comprises a first stepped surface (405) and a second stepped surface (406), and a third recessed part (403) is arranged on the side surface of the lens assembly (400); a first inclined surface (4013), a second inclined surface (4011), and a third inclined surface (4012) are formed on the bottom surface of the first recessed part (401), and a mirror (404) is obliquely arranged in the first recessed part (401), a cavity being formed between the mirror (404) and the first inclined surface (4011) and the third inclined surface (4012); a first reflective surface (4021) is formed on the bottom surface of the second recessed part (402); a third lens matrix (4032) is arranged on the end surface of the third recessed part (403); a first lens matrix (4051) is arranged on the first stepped surface (405), a second lens matrix (4061) is arranged on the second stepped surface (406), and there is a height difference between the first stepped surface (405) and the second stepped surface (406). The present invention facilitates achieving an optimal spot at the transmitting end optical fibre position and at the optical receiver (303) simultaneously.
