D300S Digital Transmission Analyzer

A transmission test module, supporting full-rate SDH/SONET and PDH/DSn testing from 2.5 Gbps (STM16/OC48) to 2.048 Mbps (E1/DS1).

Highlights

Supports STM1/4/16 and OC3/12/48 optical port testing, meeting the high-speed transmission testing requirements of backbone networks and metropolitan area networks.
Enables intelligent scanning of remote devices and automatic configuration mapping structure, greatly improving testing efficiency and reducing manual configuration errors.
Online pass-through and advanced pass-through modes support real-time overhead modification and error insertion without affecting existing network services.
High-precision APS testing: APS switching time measurement resolution reaches 1μs, accurately verifying network protection performance.
Modular platform compatibility: Based on the FT100 platform, it can be expanded with modules such as OTN, Ethernet, and synchronous testing, achieving “one machine with multiple functions
