Highlights

  • Validate the BER performance of 112G optical transceivers and silicon devices with 2-ports of the G800GE BERT, FEC, and Layer-2 packet blast capabilities using the KiOS browser application
  • Perform long-duration (timed tests) and stress tests by using Keysight’s KP4 FEC symbol error correction density distribution analysis—excellent for catching bursty errors that occur over time
  • Simplify connection of the G800GE to Keysight's M8040A high-performance BERT analyzer or Infiniium UXR Oscilloscopes for FEC-aware physical layer IEEE 802.3ck and OIF compliance tests. Use the G800GE’s FEC codeword trigger and capture option to analyze bit-errors
  • Find problems faster with KiOS browser-based single-page application (SPA), system-view of all the BERT, FEC, and packet statistics of all the lanes and ports with 1x800GE, 2x400GE, 4x200GE, and 8x100GE speed support
  • Measure line-rate BER and FEC performance in minutes, not hours— evaluate optical transceiver and silicon device BER at all Ethernet speeds simultaneously by using the patented enhanced BERT option (BERT inferred FEC)
  • Connect a module compliance board or your own development device evaluation board by using the G800GE electrical coaxial cabling system

World’s First Line-Rate 2 x 800GE Test System

Keysight’s G800GE OSFP112G and QSFP-DD800 test systems make the challenges of qualifying bit error rate (BER) and forward error correction (FEC) symbol error correction performance and stress-testing with line-rate layer 2 packet traffic on 800GE electronic devices easier and affordable. Used to validate chips, optical transceivers, or the port electronics of networking equipment, the G800GE is a purpose-built BERT and FEC test system with 112Gb electrical lane, PAM4 signaling per port that gives you the ability to find a problem in minutes, not hours. It shows a system-level view of the BER, FEC performance and packet processing of all lanes and on the ports, as desired, all at once, in real time.

MORE ACCURATE MEASUREMENTS USING ELECTRICAL COAXIAL CONNECTIVITY

The G800GE 1-port optical transceiver and 1-port interface electrical Tx/Rx coaxial interface models are a unique benchtop test chassis. The coaxial interface is an excellent medium for electrical signals. Its use results in more accurate measurements because it offers an extremely clean test signal with minimal signal loss. The coaxial interface connects with Module Compliance Boards and your device evaluation boards to validate devices under test with the G800GE’s BERT, FEC, and packet transmission capabilities.

High-Performance BERT Analyzer Synchronization

The G800GE OSFP112G and QSFP-DD800 chassis can be upgraded in the field to support interconnection and synchronization with Keysight’s M8040A high-performance BERT analyzer or Infiniium UXR Oscilloscopes. The combined system is a symbol-striped, FEC-aware physical layer BER tester for 112G electrical lanes. It is a solution for 800GE characterization, stress, and conformance tests, and to perform physical-layer channel stress and impairment of a channel. Additionally, advanced tests such as TDECQ and optical receiver stress testing (ORST) may be performed for optical transceivers in conjunction with various Keysight Layer 1 instruments such as a real-time oscilloscope, a DCA, and other equipment and accessories depending on the application.

100G Serial FEC-Aware Conformance Testing Demonstration

Reducing cost and power per transported bit, the 100G serial interface will become the workhorse for hyperscale data centers deploying increasing numbers of posrts 400GE today and 800GE ports in the future. For interoperability and conformance testing, predicting the forward error correction margin under realistic conditions requires the ability to quantify and understand error burst mechanisms. This demonstration shows such validation using Keysight's G800GE, the industry’s first electrical lane FEC-aware receiver conformance test solution for 100G serial interfaces.

Keysight and LuxshareTech interoperability demo – DesignCon 2022

Data Center Operators (DCOs) are moving towards 800GE to accelerate the upgrade cycle of switching silicon to derive power saving benefits and physical interconnect links need to scale to 112G PAM4 electrical signaling. This produces unique challenges in which all network points must be tested, including 800GE ports and 112G-per-lane interconnect.

The collaboration for 800GE readiness testing in 1x400GE mode is comprised of Keysight G800GE FEC Aware and Compliance test system using the LuxshareTech 400GE QSFP112 DR4 optical transceiver. The need for higher rate pluggable optics modules is evident and Keysight supports the 800GE eco-system to validate implementations of high bandwidth interconnect, including OSFP, QSFP-DD and QSFP form factor. In parallel, LuxshareTech will soon continue offering 800G/1.6T optics which is based on integrated photonic platform with low power electronics.

"Keysight's G800GE test system meets both the performance and verification needs of 112G-electrical-lane interconnect and infrastructure," said Mike Gao, GM of LuxshareTech Opto-electronic BU. "We are extremely pleased to deliver LuxshareTech’s industry leading 400GE QSFP112 DR4 optical transceiver to the market with silicon photonics technology, and validated using Keysight’s G800GE QSFP-DD800 BER, and FEC symbol error correction FEC Aware and Compliance test system.”
