Xgig CDFP 16-lane Interposer for PCI Express 5.0

Interposer Module for Xgig® PCI Express 5.0 Analysis Platform

This PCIe 5.0 16-lane CDFP/CopprLink™ Interposer provides a tap of PCIe data signals between two externally cable-connected CDFP/CopprLink™ devices

The VIAVI Solutions Xgig® 16-lane CDFP/CopprLink™ Interposer for PCI Express® 5.0 supports analysis of PCIe5 communication between two CDFP devices connected by external cabling.  CDFP/CopprLink™ is an emerging external cabling interface used for applications such as PCIe fabrics, artificial intelligence and machine learning.  It provides connection between the VIAVI PCIe 5.0 Analyzer/Exerciser/Jammer platform and a system under test. This Interposer installs between a CDFP/CopprLink™ host port and a CDFP/CopprLink™ attached endpoint device.  It operates at the 32GTps, PCIe 5.0 rate, across up to 16-lanes (bi-directional).
