Xgig OCP3 16-lane Interposer Module for PCI Express 5.0

Interposer Module for PCI Express 5.0 Platform

The PCIe 5.0 16-lane OCP3 Interposer provides a tap of host-system PCIe signals to OCP NIC 3.0 devices for input into the VIAVI Analyzer

The VIAVI Solutions Xgig® 16-lane OCP3 Interposer for PCI Express® 5.0 is optimized for developing, debugging and performance tuning OCP NIC 3.0 devices used in data centers.  The OCP-NIC 3.0 specification was created by the Open Compute Project® to define a data center optimized form factor for PCIe devices which will in turn support large scale artificial intelligence and machine learning adoption in data centers.  

This Interposer enables debug and verification of new ICs, new system hardware designs, FPGA firmware, validation of system BIOS and software—and supports manufacturing test.  It provides connection between the VIAVI PCIe 5.0 Analyzer/Exerciser/Jammer platform and an OCP system under test. It operates at the 32GTps, PCIe 5.0 rate, across up to 16-lanes (bi-directional).


  • Provides consistent, repeatable capture of link training, equalization negotiation and other data analysis 
  • Faster analysis and problem isolation
  • Quicker time to market and earlier revenue
  • Lower engineering costs


  • Supported by VIAVI Analyzer tools for trace capture with filter, trigger and more 
  • Supports error injection for deep system analysis
  • Works together with the 5P16 and 5P8 Analyzer/Exerciser/Jammer platforms 


  • Operates up to 32GTps, PCIe 5.0 data rates 
  • Downward compatible with PCIe 1.0, 2.0, 3.0 and 4.0, and data rates of 2.5, 5.0, 8.0 and 16GTps 
  • Supports link widths up to and including 16-lanes 
  • Supplied with high-quality custom cables for Analyzer attachment
  • Four cables provided for optional clocking sources
  • Supports Analyzer side-band signal triggering and capture via custom cable 
  • Supports Jammer error injection for deep system analysis and debug
  • Data path uses high-speed linear redrivers to ensure good signal capture with minimal tuning 
  • Interposer power is independent of host system. A 120/220 AC in, 12V/3A DC out converter is included 
  • LEDs give quick indication of power and operation 
  • Supported by VIAVI Xgig tool suite including Trace Control, Expert and Serialytics
