Title:
OPTICAL MODULE AND NETWORK DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/042178
Kind Code:
A1
Abstract:
An optical module (10) and a network device. The optical module (10) comprises an emission assembly (11), and the emission assembly (11) comprises a light source (111) used for outputting a first outgoing beam, and a first adjustment assembly (112) used for adjusting the first outgoing beam into a second outgoing beam. The first outgoing beam is a single-mode beam. The mode field diameter of the second outgoing beam is greater than the mode field diameter of the first outgoing beam. The second outgoing beam can generate M modes in a multi-mode optical fiber, and the first outgoing beam being can generate N modes in a multi-mode optical fiber, where 1 ≤ M < N. Given that it is guaranteed that a current multi-mode optical fiber layout scenario does not change, an optical signal transmission rate is improved by means of designing and modifying the optical module (10).
