- 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.
