40G/100G Modules

UX400-40G/100G Now up to 600G

This multi CFP form-factor high-speed OTN, SDH/SONET and Ethernet test module offers up to 600G traffic generation for development, verification and commissioning for today’s demanding speed requirements. As well as all the standard installation and maintenance tests, including advanced features such as OTL/STL/PCS, CAUI/XLAUI Lane BERT, overhead monitoring and byte control, Tandem Connection Monitoring, protocol capturing and decoding, traditional BERT and throughput tests, advanced OTN/SDH/SONET/PDH/DSn payload multiplexing and much more.
