Material Composition:
- Module frame: Flame‑retardant metal‑plastic composite structural housing
- Circuit substrate: Conformal coated multi‑layer industrial PCB, industrial optical transceiver components
- External interfaces: ST‑type fiber optic sockets
- Backplane connector: Gold‑plated 96‑pin industrial backplane connector
- Fastening hardware: Anti‑corrosion stainless steel locking latches
Structural Characteristics: Standard Trusted rack‑mount module form factor. Front‑panel installs ST‑fiber sockets and link status LED indicators. Rear‑side 96‑pin backplane connector exchanges data with local rack TMR main processor. Optical transmission path achieves full electrical isolation between different racks. Dual side spring latches complete mechanical locking inside rack slots.
Working Principle: Local rack safety logic data passes to T9311C module through backplane bus. Module converts electrical data signal into optical signal, transmits data stream to remote T9311C module via multi‑mode optical fiber. Remote module converts optical signal back to electrical data, delivers synchronized safety data to its local rack main processor. Bidirectional data transmission is implemented. Built‑in link monitoring detects optical power loss and channel fault, and reports fault events to local main controller.
Installation Requirements:
- Insert T9311C module into designated slot of Trusted controller rack.
- Lock dual‑side spring latches fully for reliable backplane connector contact.
- Deploy specified multi‑mode ST‑terminated optical fiber cables. Keep fiber bending radius larger than minimum allowable bending value.
- Arrange optical fiber wiring path away from high‑temperature heat sources and sharp mechanical edges.
- Complete rack protective ground connection to site safety grounding busbar.
Usage Notes:
- Do not look directly at energized optical fiber transceiver ports. Internal laser light source causes eye injury risk.
- Maintain minimum optical fiber bending radius specified in hardware manual. Excessive bending damages optical fiber core permanently.
- Clean ST‑fiber connector end‑face before installation. Dust contamination reduces optical link power and triggers communication fault.
- Confirm matched fiber type, multi‑mode fiber only for T9311C. Single‑mode fiber cannot satisfy working requirement.
- Hot‑swap operations shall strictly follow official Trusted system operation procedure.
