The NX4000 Transport Analyzer is a measuring instrument to evaluate performance, functionality and reliability of 40 Gbit/s high speed optical telecommunication systems and equipment that use not only SDH/SONET* but also Optical Transport Network (OTN)*, which is a strong candidate for Next generation Network (NGN).

SDH/SONET and OTN are high speed digital transmission schemes using an optical fiber. SDH and OTN are standardized by ITU (International Telecommunication Union). SONET is standardized by ANSI (American National Standards Institute).

• SONET/OTN/Ethernet all in one
• Field Pluggable Modules
• OC-768 / STM-256 and OTN OTU3
• 44G Ethernet over OTN: four 10G Ethernet channels via over-clocked OTU3
• ITU Compliant Tunable DWDM line side optics
• Alarm, error, thru-mode and full BER measurement of the payload
• Full editing and monitoring of Overhead data
• Flexible to support the latest optical modulation scheme such as DQPSK
