Welcome to Tech Pulse, I’m your host, Alex Johnson. Today we’re talking about Molex’s bold step toward tomorrow’s data centers with its PCIe 7.0 cabling solution. At Computex, Molex “demonstrated its Genesis cable and connector solution” capable of sustaining 128 gigatransfers per second over a full meter. Traditional PCB traces start to fall apart at those speeds, but Genesis leans on an SFF TA-1040 connector and low-loss microwave coax to keep signals clean.

Molex’s own simulations reveal insertion loss of just ‑3.4 decibels at 250 millimeters and ‑9.2 decibels at 1,000 millimeters, with crosstalk kept impressively low. The design scales from x8 to x16 and even an upcoming x20 connector, supporting up to 148 pins for massive throughput in dense server racks.

With PCI-SIG’s PCIe 7.0 specification at final draft version 0.9, we’re looking at real-world adoption late this decade or early 2030s. Stay tuned as Molex moves from prototype to production on this next-generation backbone.
