G800GE-02 OSFP800 & QSFP-DD800 800GE BERT, FEC, L2 Test Systems

Challenge: Finding Problems Faster and Earlier in the 800GE Development Cycle

800 Gigabit Ethernet (GE) technologies based on the 106.25Gb/s electrical lane signaling rates have exponentially increased the level of complexity for the development of stable port electronics in all networking devices. Now, the challenge has become characterizing and quantifying the actual bit error ratio (BER) and forward error correction (FEC) performance of IEEE802.3ck and IEEE802.3bs compatible silicon devices, application-specific integrated circuits (ASICs), optical transceivers, and fiber and copper interconnects. Quickly identifying BER and FEC performance problems at 1x800GE, 2x400GE, 4x200GE, 8x100GE and 8x100GE (ck) Ethernet port speeds is critical, as the resolution and implementation of potential solutions is complex and time-consuming. The G800GE-02 reduces this cycle time. The G800GE02 support the testing of 400GE technologies based on 53.125Gb/s electrical lane signaling to validate the performance of 1x400GE, 2x200GE, 4x100GE, and 8x50GE optical transceivers and fiber interconnects.

Solution: A simplified, affordable BERT, FEC, and L2 packet blast test system

Keysight’s G800GE-02 test systems make the challenge of qualifying BER, FEC symbol error correction performance and line rate traffic stress testing on 800GE electronic devices easier and affordable. Whether validating chips, optical transceivers, or the port electronics of networking equipment, the G800GE-02 is a purpose-built test system with 106.25Gb/s and 53.125Gb/s electrical lane 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 and FEC performance, at full line rate, of all the lanes and on the ports, over all the Ethernet speeds, as required, all at once, in real time.

The G800GE-02 test system is a compact benchtop chassis. It may also be installed on a rackmount, as required. The G800GE-02 is provided with the Layer 1 BERT, FEC, and Layer 2 test software called KiOS. The KiOS single-page application (SPA) uses the Google Chrome browser implementation. It makes set up so easy and fast that you can start testing and generating PASS/FAIL test reports by using your tolerance and limits within minutes. KiOS has REST API and Python library to facilitate a rapid build of test automation suites.

G800GE-02 chassis are available in four models:

• G800GE OSFP-02, 800GE, 2-port OSFP800, Layer 1 BERT, FEC and L2 test and measurement system, fixed chassis (941-0086).

• G800GE OSFP-COAX-02, 800GE, 1-port OSFP800, 1-port electrical coax breakout, Layer 1 BERT, FEC and L2 test and measurement system, fixed chassis (941-0087).

-       The 941-0087 is recommended for use with the Keysight M8040A BERT Analyzer, and the Infiniium UXR‑Series Oscilloscopes.

• G800GE QSFP-DD-02, 800GE, 2-port QSFP-DD800, Layer 1 BERT, FEC and L2 test and measurement system, fixed chassis (941-0088).

• G800GE QSFP-DD-COAX-02, 800GE, 1-port QSFP-DD800, 1-port electrical coax breakout, Layer 1 BERT, FEC and L2 test and measurement system, fixed chassis (941-0089).

-       We recommend the 941-0089 for use with the Keysight M8040A BERT Analyzer, and the Infiniium UXR‑Series Oscilloscopes.

• All models include support for 1x800GE, 2x400GE, 4x200GE, 8x100GE and 8x100GE (ck), plus 1x400GE, 2x200GE, 4x100GE and 8x50GE Ethernet speeds, BER test, FEC test, and Layer 2 packet blast capabilities. No additional option purchase is necessary for complete Ethernet speed support.

-       Advanced options such as BERT inferred FEC, FEC codeword trigger and capture, and synchronization to the Keysight’s Layer 1 instruments are available as purchased options. Both factory installed and field upgrade options are available.

The RS-544 (KP4) FEC symbol error correction test capability simplifies FEC testing over electrical lanes, just as easily as the built-in Layer 1 BER features. Keysight’s FEC codeword bit-error density distribution analysis (the FEC tail) shows the symbol error correction performance, error density distribution, FEC margin, and Frame Loss Ratio (FLR), as well as many other advanced and useful measurements. It is an excellent system to use to perform long-duration performance and stress tests. It simply cannot be made any easier to use.

The patented Enhanced BERT option with BERT-inferred FEC analysis provides your development teams test capabilities to quickly pinpoint problems and to predict excellent or poor BER and FEC symbol error correction performance on a given device. This feature analyzes all the Ethernet speeds that the given device supports, simultaneously with the full statistical analysis of the G800GE-02 made available, all at once.

Innovation on the G800GE-02 did not stop at the Enhanced BERT-inferred FEC option. The G800GE-02 offers a FEC Trigger and Capture option. This feature provides deep insight into exactly where the bit errors are located inside a FEC codeword for all speeds. You can set the Ethernet speed, trigger logic, trigger bit error, or FEC codeword error thresholds as to how many and which bit-errors or FEC symbol errors you want to capture. Then, a graphics capture display shows where the bit errors occurred and provides a summary analysis report of the events that occurred in a structured and organized manner.
