Working Principle

1. Electrical Ethernet signal from RJ45 copper port enters internal switching chip after EMC filtering circuit
2. Chip completes frame receiving, error verification and address table forwarding via store-and-forward logic
3. Electrical signal converts to optical modulation signal via fiber transceiver module and transmits through single-mode fiber
4. Receiving terminal optical module converts light signal back to standard electrical Ethernet signal for copper port output
5. Galvanic isolation circuit separates copper port ground and fiber optical circuit ground to cut ground loop current caused by potential difference between field and control room

Installation Requirements

1. Snap mount horizontally or vertically on standard 35mm DIN rail inside control cabinet; allow 20mm surrounding clearance for heat dissipation
2. DC power wiring use 0.75–1.5mm² twisted copper wire; positive and negative polarity strictly follow terminal marking to avoid reverse power supply damage
3. Single-mode fiber cable must adopt duplex SC patch cord matching 9/125μm fiber core; fiber bending radius minimum 25mm to prevent optical power attenuation
4. All RJ45 copper wiring use shielded CAT5e industrial Ethernet cable with 360° shielding grounding at both ends
5. Ambient operating temperature range: -40°C to +70°C (EEC enhanced environmental version)
6. Relative humidity operating range: 5%–95% non-condensing; avoid direct contact with water splash and corrosive gas environment

Usage Precautions

1. Do not touch fiber port optical transmitter/receiver lens with bare hands; dust or fingerprint residue causes severe signal attenuation
2. Disconnect power before plugging/unplugging fiber cable to avoid transient optical power impact damaging transceiver chip
3. Do not use multimode fiber with this single-mode model; mismatched fiber leads to zero signal transmission
4. Regularly inspect fiber port lens cleaning every 6 months in dusty industrial environments with special optical fiber lens cleaning paper
5. Avoid installing near high-power inverters, welding equipment or high-voltage transformers without shielding isolation
6. Do not exceed maximum 32.5km fiber transmission distance; over-range triggers continuous link loss fault alarm
