T1 to 100G

All-in-one Optical and Service Test Platform

The TX300s-100G, with the latest technology in pluggable physical interfaces, is a perfect complement to the TX300s Platform, extending its testing range to 100 Gbps. Compatibility with the companion TX320sm option offers a complete 64k to 100G test solution in a compact portable package.

Installation, commissioning, monitoring and maintenance of Ethernet, OTN and SDH/SONET networks is simplified thanks to a combination of intuitive features and powerful test functions. Fast troubleshooting and comprehensive analysis of transmission problems can be performed using its common graphical user interface. Novice users benefit from the easy-to-use GUI, while experienced users will appreciate an array of advanced features such as OTL/PCS, CAUI-4/XLAUI Lane BERT, Service Disruption, overhead monitor/control, Tandem Connection Monitoring, Protocol Capture/Decode, BERT, Throughput test, and much more.
