VIAVI, the leader in metro Ethernet testing, recently added a 400G all-in-one portable tester to their metro portfolio, the OneAdvisor-1000. The powerful tool has the same test scripts and GUI as the other VIAVI metro products, supports multiple line rates, and runs Optics Self-Test/RFC2544/Y.1564 at 400GE. OneAdvisor-1000 supports multiple pluggable types including QSFP-DD, and its industry-leading battery life is critical for field use. For long range applications, the OneAdvisor-1000 has the power, cooling, and controls to support ZR optics. Go to viavisolutions.com to request a demo or a quote.
