Fiber Optic Connection Overview
The module connects to the drive (NAMC/NDCO board) via fiber optic
cables. Please note the color coding of the fiber optic connectors:
- Blue connector should connect to the Blue receiver (RXD)
- Grey (or Black) connector should connect to the Grey transmitter
(TXD)
- Multiple modules in a single channel are connected in a ring
topology
Fiber Optic Handling Precautions
- Handle fiber optics with care
- Maximum long-term tensile load: 1 N
- Minimum long-term bend radius: 25 mm
- Do not touch the fiber optic tips; they are very sensitive to dust
- Use grommets where fiber optics pass through holes
Terminal Connections
The terminals connected to NTAC-02, NDIO-02, and NAIO-03 modules
are shown in the table above.
