D450S Digital Transmission Analyzer

A transmission test module, supporting full-rate SDH/SONET and PDH/DSn testing from 1.5 Mbps (DS1/E1) to 10 Gbps (STM64/OC192).

Highlights

10G high-speed full coverage: Industry-leading STM64/OC192 testing capabilities meet the high-speed transmission testing needs of backbone networks and metropolitan area network core layers.
A single module supports SDH/PDH/Ethernet/PTN testing, eliminating the need for stacking multiple devices and reducing procurement and operation and maintenance costs.
Supports intelligent scanning, automatic channel discovery, and signal structure recognition, greatly improving test efficiency and accuracy.
Enables overhead modification and error alarm insertion without interrupting services, enabling accurate fault simulation and location.
Built-in clock accuracy is ±0.5ppm, loop delay resolution is at the microsecond level, and APS switching test resolution is 1ms.
Supports FT100 and FT6800 platforms, and can flexibly expand test modules such as OTN, synchronization, and Ethernet.
