The VIAVI Solutions ANT-20SE Advanced Network Tester is a portable instrument in VIAVI's ANT family (formerly Acterna/WWG Wandel & Goltermann) used for advanced network testing. The ANT-20SE designation, along with references to 10Gig capabilities, indicates support for testing high-speed links, including 10 Gigabit Ethernet. As part of the legacy ANT-20 line, the ANT-20SE is documented by VIAVI and third-party listings as a discontinued model. This device is designed to characterize network performance and validate transport-network behavior in telecom and data-network environments.
