Overview

The client is a well-known internet company, founded in 2015. It features a social e-commerce model that allows users to enjoy better prices through a new operating model. Users can purchase a variety of goods on the platform, including daily necessities, electronics, clothing, and more. The platform is committed to providing cost-effective goods and services, which attracts a large number of users. The surge in the number of users has created an urgent need for better server links. In some cases, the losses of conventional RISER cables are no longer sufficient. X86 servers are gradually transitioning from EGS platform to BHS, and the requirements for link loss are becoming more and more stringent. In this context, Longtek's high-speed interconnection DA CEM product solution came into being.

Challenges

With the rapid growth of customer services, traditional server links can no longer meet customers' high-performance computing needs, which seriously affects the data transmission efficiency and system stability of enterprises, and greatly affects user experience. In the face of these situations, high-speed interconnection provides targeted solutions and launches DA CEM products. Compared with the traditional PCB solder board solution, DA CEM uses direct solder technology to effectively improve the signal transmission quality. In addition, the DA CEM is a hybrid connector with a crimped power pin for easy rework and repair, greatly improving ease of maintenance. It is also backwards compatible with PCIe 4/3/2/1 specifications. By adopting DA CEM, the customer's server link problem has been solved with high quality, which not only improves the data transmission efficiency, but also enhances the stability and maintainability of the system.

Benefits
