The VeEX UX400 is the smallest multi-service transport test solution to offer test capabilities ranging from DS1/E1 all the way up to 6x 100G traffic generation, supporting the latest 100G/40G optical pluggable form factors (CFP4, CFP2, CFP, QSFP28, QSFP+, no adapters required). Its modular architecture allows for up to six independent test modules and up to twelve concurrent tests or combinations of tests, including legacy PDH/DSn, SDH/SONET, OTN, Ethernet, Fibre Channel, CPRI/OBSAI, C/DWDM spectrum analysis and more. The platform's software architecture has been developed so that multiple users or scripts are able to access and operate different test modules at the same time, maximizing the use of resources. A battery backup option is available for the portable UX400 platform. Test modules can also operate in a standard 19" rack – the UX400R, when portability or battery operation is not needed.
