FreyaCompact ANLT OSFP Test Appliance
The industry's first dedicated 112G SerDes Auto-Negotiation & Link Training (AN/LT) test solution
The FreyaCompact AN/LT Test Appliance OSFP is designed specifically for Ethernet AN/LT testing at 56G/112G PAM4 SerDes speeds.
Ideally Auto-Negotiation & Link Training are initiated automatically, and the two devices run through the different states in the protocols to negotiate speed and tune to optimal settings. However not all endpoints behave the same and interpretations and implementations of the standards varies. Also, the quality of the AN/LT training results are not always consistent which can lead to erratic link stability.
The FreyaCompact AN/LT Test Appliance allows thorough testing of the endpoint behavior. It provides insight, visibility, and configuration possibilities to the AN and LT process making it easy to analyze DUT behavior during AN/LT, and configure and optimize the relevant AN parameters and LT coefficients.
Leveraging Xena’s award-winning Freya 800G test modules, the FreyaCompact AN/LT Test Appliance is a small 1U “desktop” tester that is easy to transport from site to site in a 19” flight case. It’s available in QSFP-DD (C-Freya-800G-ANLT) and OSFP (C-Freya-800G-ANLT-OSFP) versions.
The advanced AN/LT test capabilities can also be enabled on “standard” Freya modules using a dedicated AN/LT Test Appliance license “Freya-ANLT”.
Layer 1 Test Tools
The FreyaCompact AN/LT Test Appliance includes ValkyrieManager, Xena’s user-friendly management software which supports the same L1 features as the Freya test modules incl.: PRBS, single stream TGA for PHY/PCS testing, Advanced PMA and PCS/FEC Error Injection, lane skewing & swapping, and ppm sweeping.
Also included is the Xena OpenAutomation (XOA) AN/LT Test Utility and the AN/LT Protocol Test Suite for performance and conformance testing.
The Xena OpenAutomation (XOA) AN/LT Test Utility is a command line tool for Interactive AN/LT Protocol Testing with single stepping of the LT protocol towards the DUT while providing statistics and logging.
The Xena OpenAutomation (XOA) AN/LT Test Suite is designed for performance and compliance testing. It can be orchestrated from third party analyzers or automation systems through its REST API or run as a stand-alone application together with the XOA AN/LT Test Suite Application.
