As the demands of high-performance computing grow—driven by AI, big data, machine learning, and other cutting-edge applications—data centers are under pressure to process and transfer more information, faster than ever before. Systems such as servers, routers, external storage arrays, and inter-rack cabling are now transmitting exponentially more data, with transfer rates scaling up by as much as 100 times compared to just a few years ago.
This dramatic shift is exposing a critical performance bottleneck: the cables and connectors responsible for managing these massive data flows. If they can’t keep up, neither can the rest of the system.
The EMI Shielding Challenge in Compact Cable Systems
With faster data rates come tighter electromagnetic interference (EMI) and radio frequency interference (RFI) control requirements. At the same time, the physical space available for shielding components is shrinking—especially in tightly packed data center environments where wire densities are high and miniaturization is essential.
As a result, EMI shielding for cables must not only meet stringent performance criteria, but also be compact enough to fit within constrained designs. Even microscopic gaps may require shielding to preserve signal integrity, and in some cases, gaskets or conductive coatings are used to isolate adjacent cables to avoid cross-talk.
Despite the limited space, these solutions must remain highly effective and scalable for mass production—without compromising speed or reliability.
Don’t Overlook Connector Shielding
Connectors play just as vital a role as cables. Today’s high-speed backplane connectors often operate at rates up to 112 or even 224 Gbps, using hundreds of differential pairs. Each pair demands its own shielding or isolation, presenting a significant challenge: how to deliver precise, high-conductivity shielding within ultra-thin, tightly engineered gaskets.
Optical transceivers also present their own set of EMI challenges, requiring pinpoint shielding across small seams in the device housing or connector interfaces. Without the right EMI mitigation strategy, even the most advanced optical systems can suffer performance degradation.
