Technical Specifications
Cable type: duplex multi-mode optical fiber. Length: 10 meters. Connector type: ST standard connector. Wavelength: 850nm. Maximum bandwidth: 1Gbps. Attenuation: <3.5dB/km @ 850nm. Operating temperature range: -40°C to +85°C. Protection rating: OFNR. Minimum bend radius: 20× cable diameter.
Functional Features
Fiber optic construction provides complete immunity to electromagnetic and radio frequency interference. Full galvanic isolation eliminates ground loop currents between remotely located equipment. High bandwidth supports real-time high-speed industrial communication. The rugged OFNR jacket meets industrial flame retardant requirements. ST connectors ensure stable and repeatable optical connections.
Application Scenarios
It applies to long-distance communication between Ovation DCS chassis, cross-building plant control networks, high-EMI manufacturing floors, substation control systems, and data links between process areas with significant ground potential differences.
Performance Parameters
Maximum data rate: 1Gbps. Insertion loss: <0.5dB per connector. Attenuation: <3.5dB/km. EMI rejection: >60dB. Operating temperature range: -40°C to +85°C. Minimum bend radius: 20× outer diameter.
Material Composition
Fiber core: high-purity fused silica glass. Cladding: polymer matching cladding. Strength member: aramid yarn. Jacket: industrial-grade flame-retardant PVC. Connector: ceramic ferrule with gold-plated bronze body.
Structural Characteristics
It features a duplex zipcord construction, ST type bayonet connectors at both ends, aramid tensile strength members, flame-retardant outer jacket, and molded strain relief boots at both connector ends.
Working Principle
It transmits data via modulated light signals through the optical fiber core. Electrical signals from control equipment are converted to light signals at the transmitting end, propagate through the fiber with total electrical isolation, and are converted back to electrical signals at the receiving end, enabling noise-free data transmission across long distances and harsh electrical environments.
Installation Requirements
Clean fiber end faces with approved cleaning tools before connection. Align ST connector keys and seat fully before locking the bayonet nut. Maintain minimum bend radius at all points along the cable run. Route cable away from high-temperature sources and sharp edges. Secure cable with strain relief at both ends to avoid connector stress.
