Abstract

The invention discloses an optical fiber coupling module and relates to an optical component in an active optical cable. An active optical cable in the prior art has defects such as large module size, a limited number of transmitting and receiving ports, complex process and the like. According to the optical fiber coupling module, a 45-degree oblique end surface optical fiber array is coupled to a laser array; a flat end surface optical fiber array is coupled to an optical detector through a right-angle prism and a micro lens array; and a transmitting assembly and a receiving assembly are integrated in one module. The optical fiber coupling module has the advantages of compact structure, high density interconnect and simple process.

Description

technical field [0001] The invention belongs to optical components in active optical cables, in particular to a high-density multimode fiber coupling module. Background technique [0002] With the advent of the era of big data, bandwidth-consuming Internet applications such as streaming media, social networking, and cloud computing have flourished, and the scale of the data centers that support them has become larger and larger. Data exchange puts forward higher requirements on interconnection speed and density. Traditional electronic interconnection technology cannot meet the needs of new data centers. Currently, active optical cables (AOC) are commonly used for interconnection between cabinets. In systems such as high-performance computers and large-capacity storage, active optical cables are often used to achieve high-speed interconnection between devices. [0003] Active optical cable is an integrated photoelectric module, which consists of a pair of optical fiber tran...
