NX4000 40G TRANSPORT ANALYZER

The NX4000 40G 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)*.
By using a standards based 40 Gbit/s transponder, the NX4000 can easily support various distances, optical modulation formats and wavelengths.

FEATURES
FUNCTIONS
OTHER FUNCTIONS

Built for 40G Next Generation SONET/SDH/OTN networks the NX4000 is designed to measure the transmission and reception of communication frames, alarm/error characteristics, and the transmission characteristics, such as the transmission delay time. The NX4000 supports multiple optical modulators and wavelength tunable transponders providing measurement solutions tailored to the needs of customers. In addition, the NX4000 can also be used to measure non-frame signals.

SDH/SONET and OTN are high speed digital transmission protocols for optical networks. SDH and OTN are standardized by ITU (International Telecommunication Union).

Interface Capabilities

Various Modulation Formats

By using a standards based 40 Gbit/s transponder, the NX4000 can easily support various optical modulation formats including those listed below.

40/43 Gbit/s NRZ optical interface (NX4120, dual rate)
43 Gbit/s DPSK optical interface, C-band (planned)
43/44 Gbit/s DQPSK optical interface (NX4121, C-band)
43/44 Gbit/s DQPSK optical interface (NX4121, L-band)
43 Gbit/s ODB optical interface, C-band (planned)

Main Measurement Functions

Various alarm and error measurements
Alarms and errors are generated in a variety of modes for SONET/SDH/OTN frames and status and measurement results are displayed.
Bit error (BER) measurement
Bit errors in the payload and non-frame bit errors at 40/43/44 Gbit/s can be measured in addition to the parity errors in the overhead.
Delay time measurement
A transmission delay time from the signal transmission through the decive or network can be measured at a resolution of 0.1 µsec.
Multiple measurements
Not only OTN frames but also mapped multiple channels can be measured at the same time.

Editing and Monitoring

Editing and Monitoring Function

Frame editing
The overhead of the SONET/SDH frame and OTN frame can be freely edited.
Frame monitoring
The overhead and payload of the SONET/SDH frame and OTN frame can be monitored.
Trace message
The trace message of the section (J0) and Path (J1) can be edited, and the trace message in a received frame can be monitored and displayed. Various trace messages of the OTN frame can also be edited and monitored.

Ease of Operation

Stress-free operation
Reduces the setup time and contributes to a reduction in the turn around time for automated systems.
Direct operation with touch panel on the large 10.4-inch display
The settings can be configured by directly touching the GUI window eliminating the need for a mouse or separate PC. The NX4000 provides the ability for the user to select what information is displayed using four configurable workspaces.
Remote Operation
The NX4000 can be remotely controlled via an Ethernet LAN connection using VNC software which provides the exact same user interface as the main display on the unit.

Selection for Each Test

Select Extension Modules Suitable for the Solution

Each function is configured with functional modules.
Only necessary modules need to be selected to build the optical system.
Pluggable modules provide for a tailored solution.

SONET/SDH test system
System can be upgraded at minimum cost.

OTN test system
NX4000 can be upgraded for OTN testing by adding a single module.

Optical modulation formats
Only optical interface modules need to be replaced to use the unit for various optical modulation formats.
