AI Technical Summary

Technical Problem

Within a limited space, the packaging size of optical modules is restricted, making it difficult to accommodate more optical devices. Furthermore, the ever-increasing demand for transmission rates leads to increased circuit wiring density and low space utilization.

Method used

Design an optical module comprising a mounting section and a storage section on a circuit board. An optical component is housed in the mounting section, and an optical fiber component is located in the storage section. Optical lens components are optically coupled to the optical fiber component, and the beam propagation direction is changed by a lens array to achieve composite utilization of space.

Benefits of technology

Achieving higher transmission rates (such as 800Gbps and 1.6Tbps) within a limited space improves space utilization, reduces the space occupied by lenses on the circuit board, and enhances the capacity to accommodate optical components.

Abstract

This application discloses an optical module comprising: a circuit board including an optical port and an electrical port disposed opposite each other along an axial direction; a mounting portion disposed on the circuit board and located between the optical port and the electrical port; a receiving portion extending axially from the optical port towards the mounting portion and connecting the mounting portion and the optical port; an optical component disposed within the mounting portion for transmitting and receiving optical signals; an optical fiber component disposed within the receiving portion and partially located within the mounting portion; and an optical lens component disposed within the mounting portion and optically coupled to the optical fiber component. Through this method, this application enables the optical component and the optical fiber component to be integrated into the circuit board, achieving combined use of the internal space of the circuit board, effectively improving space utilization, and reducing the size of the optical module.
