Technical Specifications Plastic optical fiber core, length 0.35 meter. Supports high‑speed optical signal transmission. Operating temperature ‑40 ℃ to +85 ℃, storage temperature ‑40 ℃ to +85 ℃. Resists electromagnetic interference. Matched with ABB drive optical transceiver interface.
Functional Features Transmits trigger optical signal from main control board to power unit. Returns power unit hardware status feedback optical signal to control board. Optical transmission completely isolates high‑voltage and low‑voltage circuit. Resists strong electromagnetic interference inside power cabinet. Flexible structure adapts internal cabinet wiring layout.
Application Scenarios Optical signal transmission spare part for ABB high‑power industrial converter. Used for replacement of aging optical fiber inside drive cabinet.
Performance Parameters Low optical signal attenuation. Stable bidirectional optical signal transmission. Excellent anti‑electromagnetic‑interference performance.
Material Composition Plastic optical fiber core. Wear‑resistant outer protective sheath. Precision optical connector heads at both ends. Reinforced stress‑relief structure for connector root.
Structural Characteristics Short‑length flexible optical cable assembly. Both ends equipped with dedicated optical plug‑in connectors. Outer sheath protects internal fiber core from mechanical damage.
Working Principle Electrical control signal is converted into optical signal by transmitting‑end optical transceiver. Optical signal transmits along fiber core to receiving‑end connector. Receiving‑end optical transceiver converts optical signal back into electrical signal for circuit processing. High‑voltage electromagnetic noise cannot pass through optical medium.
Installation Requirements Shut down converter main power and auxiliary power before replacement. Remove old optical fiber connectors carefully. Insert DCF803‑0035 two‑end optical plugs into corresponding optical transceiver sockets. Ensure connectors are fully seated. Arrange cable routing without sharp bending. Restore equipment power and verify trigger and feedback signal communication.
Usage Notes Do not bend optical fiber with sharp angle, minimum bending radius meets specification. Keep optical connector end face clean, avoid dust and scratch. Do not pull cable body by force. Confirm optical signal communication status after replacement.
