Spezifikationen
AFBR-1521CZ is a Broadcom Versatile Link horizontal plastic fiber optic transmitter with 650nm red LED light source, perfectly matched with AFBR-2521CZ receiver to form complete galvanically isolated fiber link. It targets low-speed control signal transmission under ultra-wide temperature environments for industrial drives, new energy equipment and factory automation systems.
👉 It is not the high-speed 50MBd AFBR-1624Z transmitter nor the ordinary HFBR-1521Z limited to +70°C max temperature.
👉 It is an extended high-temperature 4-pin POF transmitter supporting ultra-long-distance PCS fiber transmission, with dual 3.3V/5V power compatibility, ideal for high-temperature cabinet and harsh outdoor industrial control signal isolation transmission.
Key Features of AFBR-1521CZ Fiber Optic Transmitter
Power electronics and automation engineers select AFBR-1521CZ for ultra-wide temperature tolerance, ultra-long transmission distance and flexible system compatibility:
- Supports DC to 5 MBd digital signal transmission, peak optical wavelength at 650nm red light, stable matching with AFBR-2521CZ receiver for low-speed fieldbus and switch signal links
- Dual fiber compatibility: up to 58 meters stable transmission via 1mm core POF plastic fiber; up to 500 meters ultra-long-distance transmission via 200μm PCS hard-clad silica fiber
- Built-in integrated LED drive circuit, TTL compatible electrical input, can be directly driven by MCU, FPGA, DSP and PLC IO without extra level conversion circuits
- Fast switching performance: typical 10ns rise time and 10ns fall time, low pulse distortion to guarantee reliable transmission of PWM trigger and switching digital signals
- Universal dual power supply design: compatible with 3.3V (3.135V~3.465V) and 5V (4.75V~5.25V) industrial control power rails, fits both new low-voltage and legacy 5V mainboards
- Horizontal 4-pin through-hole Versatile Link flame-retardant plastic housing, supports interlock stacking of multiple modules to save PCB layout space; matched simplex/duplex push-in fiber connectors for fast field wiring without special tools
- Ultra-wide industrial temperature range: -40°C ~ +95°C, stable optical and electrical performance under long-time continuous high-temperature cabinet operation, better heat resistance than standard HFBR series modules
- Complete optical galvanic isolation thoroughly eliminates ground loop interference and high dv/dt EMI noise generated by IGBT/MOSFET high-speed power switching
- Electrical parameters: max forward voltage 2.3V, max forward drive current 30mA, low power consumption for 24-hour uninterrupted industrial equipment operation
- RoHS6 lead-free and REACH compliant, tube tray packaging, MSL3 moisture sensitivity rating, compatible with automated wave soldering and automatic component insertion production lines
- Cross-series interoperability, compatible with HFBR-2521Z and AFBR-2521CZ receivers, convenient for old equipment hardware upgrade and replacement
- Mature mass-production optoelectronic device with stable long-lifecycle component supply for new energy power conversion, industrial drive and harsh environment automation batch projects
