Material Composition:
- Conductors: Multi‑strand tinned copper wires
- Inner insulation: Flame‑retardant PVC compound
- Shielding layer: Copper‑alloy braided shielding mesh

- Connectors: ODU 12‑pin circular gold‑plated contact assemblies, metal locking shell
- Strain‑relief components: Rubber strain‑relief sleeves at cable‑connector transition position
Structural Characteristics: Complete pre‑assembled cable assembly. Two cable ends are fitted with 12‑pin ODU circular locking connectors. Internal multi‑pair differential signal conductors are arranged, wrapped by full‑coverage braided shielding layer. Outer abrasion‑resistant protective jacket covers whole cable length. Strain‑relief structure eliminates mechanical stress transfer to internal conductor‑connector joint points.
Working Principle: Transmits differential TMR communication signal from T8312 adapter port to expander chassis communication port. Braided shielding layer diverts external electromagnetic noise to grounding potential, avoids noise coupling into differential signal pairs. Matched characteristic impedance ensures signal integrity for 1.5 Mbps high‑speed inter‑chassis data transmission.
Installation Requirements:
- Align connector pin notch, insert ODU connector fully and rotate locking ring until complete lock engagement.
- Reserve cable laying slack, avoid applying tensile pulling force onto cable‑connector joint.
- Maintain cable bending radius larger than minimum allowable bending radius during routing.
- Route expander communication cable separately away from high‑voltage power cables.
- Connect cable shielding terminal to chassis protective grounding point according to official grounding drawing.
Usage Notes:
- Do not use non‑original substitute cables. Impedance mismatch will cause inter‑chassis communication error.
- Do not drag cable by pulling connector housing. Mechanical damage will occur inside connector contact parts.
- Avoid placing cable close to high‑temperature equipment surfaces. High temperature accelerates outer jacket aging.
- Periodically inspect connector locking state and cable outer‑jacket integrity for vibration‑intensive working locations.
