AI Technical Summary
Traditional electrical interconnect technologies in network equipment are limited by chip manufacturing processes, heat dissipation, and link loss control, making them unable to meet the requirements of high-speed information transmission. Furthermore, the high failure rate of onboard optical modules results in low maintenance flexibility for network equipment.
The design employs a line card, which includes a packaging substrate and an optical engine. The light source module cage and the optical engine are pluggable. The light source module is placed outside the line card, and optical signals are interconnected through an optical backplane. The optical engine and the processing chip are co-packaged to reduce electrical distance and signal loss.
It improves the maintenance flexibility and maintainability of the light source module of network equipment, increases the interface density and transmission capacity of network equipment, reduces the cost and power consumption of line cards, and achieves stable transmission of high-speed signals.
