The Molex BiPass solution allows designers to bypass the lossy printed circuit board through high-speed twinax cabling, providing lower insertion loss, efficient thermal management, and great signal integrity performance. Who does it benefit? The data center and telecom infrastructure industries are constantly changing and progressing. The BiPass solution can help alleviate several of the issues that manufacturers are having. From space constraints to heat dissipation to increasing speed needs, Molex can help provide a quality system to take your end products to the next level. Overview In data centers and telecommunication infrastructure, 56 and 112 Gbps PAM-4 signaling is the latest development in serial data signal formats. Implementation of high data rate protocols such as PAM-4 require a clean channel (i.e., low signal-to-noise ratios). Compared to PCB materials, BiPass I/O Cable Assemblies dramatically reduce insertion loss between the ASIC and the front panel I/O, creating greater channel margins. As signal integrity becomes paramount, data center and network designers can no longer utilize inexpensive FR4 material. Yet, better-performing PCB materials come at a price premium. BiPass I/O Cable Assemblies reduce the overall signal integrity requirements of the main PCB by removing the sensitive high-speed signals via twinax. With the move to PAM-4, ASICs used in data centers and networks are being asked to do more, resulting in increased energy consumption. As a result, designers have turned to installing retimers on the main PCB or have relied upon them in the active optical transceivers to enable a “turning down” of the ASIC.
