MACOM Supports PCIe and CXL Connectivity Over Optical Fiber with High Performance Chipset
As data centers and high-performance computing environments demand increasing bandwidth and reach, MACOM’s chipset enables PCIe extension up to 100 meters over multimode fiber. The chipset supports eight PCIe 6.0 lanes at 64 Gbps PAM4, while also transporting critical sideband signals including clock, reset, wake and communication channels like USB and Ethernet over an additional fiber. This ensures full PCIe bus transparency across extended distances.
PCIe is a key enabler for disaggregated computing, providing high bandwidth connections between components like GPU to GPU and CPUs to memory. Unlike traditional server architectures that rely on bundled hardware and layered network protocols, disaggregated computing uses photonic interconnects to link resources directly. This reduces latency, lowers power consumption and allows flexible scaling and can provide a faster, more efficient computing model.
“Extending PCIe over fiber is essential for next generation disaggregated computing infrastructure,” said
MACOM will demonstrate its new PCIe 6.0 solution at CIOE 2025 in Stand 11D31 from
