NextStream Connector System

Molex NextStream Connector System features high-speed data transmission rates up to 64Gbps PAM-4 and PCIe Gen 6 standards, ideal for data-intensive applications. The connector system offers an internal active re-driver channel that improves signal loss performance and system gain ratings over long distances, which is critical in low-latency data uses. The NextStream series provides future-proof systems via an upgrade capability to PCIe Gen 7 with 128Gbps PAM-4 data rates, allowing for user flexibility and growth. The Molex NextStream Connector System possesses 38 to 154 circuits and supports standardized applications and protocols. The connector system ensures signal integrity (SI) for various applications, including artificial intelligence (AI) infrastructure, servers, data storage, networking, and consumer devices.
