Near-Zero Latency. Zero-Distance Purity. Absolute Gen5 Velocity
As the industry transitions to PCIe Gen5, IT architects are encountering a common physical bottleneck: the lack of onboard NVMe connectivity. With most enterprise platforms offering only one or two native Gen5 M.2 slots, scaling high-speed infrastructure has historically meant compromising on signal integrity or latency. The Rocket 1604L, an Gen5 x16 M.2 Expansion Add-In-Card, was engineered to address this growing problem.
The Signal Integrity Revolution - Motherboard-Grade Stability: Unlike traditional passive bifurcation cards that suffer from signal attenuation at 32GT/s, the Rocket 1604's integrated Astera Labs Gen5 Retimer actively terminates incoming signals, eliminates electrical noise, and re-transmits a bit-perfect, "clean" signal to your devices. The result? 100% data integrity across all four M.2 ports - the exact same performance and reliability as a native motherboard-integrated slot!
