The NTK557NAE5 is a high-capacity digital cross-connect module used in OME 5100 / 5200 / 6500 optical transport nodes.
It is responsible for switching and grooming telecom traffic inside the chassis, especially:
- VT1.5 / VC-12 circuit mapping (SONET/SDH)
- 80G switching fabric capacity (system-level cross-connect)
- Traffic routing between optical line/service cards
- Synchronization and transport layer switching functions
