Description

Technical Field

[0001] The present invention relates to the field of optical communication technology, and in particular to an optical module circuit aggregation design system and a design method. Background Art

[0002] Optical communication technology uses light waves as a transmission medium. Light waves and radio waves are both electromagnetic waves, but light waves have higher frequencies and shorter wavelengths than radio waves. Therefore, optical communication offers advantages such as wide transmission bandwidth, high communication capacity, and strong resistance to electromagnetic interference. With the rapid development of optical communication technology, the use of optical modules is becoming increasingly popular.

[0003] The stable operation of optical modules is crucial to the smooth operation of optical communications. Optical communications between base stations are typically achieved by connecting optical modules using optical fibers. However, if any optical module on a single optical fiber transmission chain within a base station fails, signal transmission along the entire line will be interrupted. In existing technologies, when such a failure occurs on a line, communication operations at the base station where the optical module resides must be suspended for emergency repairs, significantly impacting line efficiency.

With this design, the first base station 1 serves as a node in an optical fiber transmission chain. The first D optical module 105 is added as the backup optical module to readily compensate for any failure or damage of the common optical modules within the station. This compensates for optical signal-to-optical signal transmission through electrical signal-to-electrical signal transmission, proactively responding and promptly ensuring normal communication on the line.

This design eliminates the need for serial connection between the regular optical fiber transmission chains or the backup optical fiber transmission chains, ensuring that the multiple optical fiber transmission chains between the base stations transmit optical signals linearly and incoherently.

[0041] In one embodiment, each group of optical modules includes a TOSA unit for converting an electrical signal into an optical signal and a ROSA unit for converting an optical signal into an electrical signal;
