Description

Optical transceiver components and fiber optic cable modules

technical field

The utility model relates to the technical field of optical fiber communication, in particular to an optical transceiver assembly and an optical fiber cable module.

Background technique

In the application of optical fiber communication technology, it is necessary to convert an electrical signal into an optical signal through an optical emission subassembly (such as a laser), and then couple the optical signal into an optical fiber that conducts the optical signal.

At present, the demand for computing devices continues to rise, and even the demand for computing devices to achieve higher performance is also increasing. However, traditional electrical I/O (input/output) signal transmission is not expected to keep pace with the demand for increased performance, especially for future high-performance computing expectations. Today, I/O signals are routed electrically to and from the processor through the circuit board and out to peripheral devices. Electrical signals must pass through solder joints, cables, and other electrical conductors. Therefore, the electrical I/O signal rate is limited by the electrical characteristics of the electrical connector.

Traditional telecommunication transmission systems are gradually being replaced by optical fiber transmission systems. Since the optical fiber transmission system does not have bandwidth limitations, it has the advantages of high-speed transmission, long transmission distance, and materials that are not interfered by electromagnetic waves. Therefore, the electronics industry is currently researching and developing in the direction of optical fiber transmission.

However, in recent years, further miniaturization of optical modules such as optical transceivers has been demanded, and thus it is necessary to optimize the structure of optical fiber transmission systems.
