The AFBR-POC205A2 belongs to the Broadcom® Power Components product family. The device converts optical power to electrical power for applications that require complete electrical isolation in highly demanding industrial environments and applications. The AFBR-POC205A2 is an excellent choice for powering electronic circuitry where electrical wired solutions are not feasible due to high voltage, electromagnetic interference, or strong magnetic fields.
The AFBR-POC205A2 is based on a patented multi-junction compound semiconductor device that is optimized for an optical input wavelength range of 840 nm to 860 nm. Therefore, this device is ideal for 850 nm, a common wavelength for low-cost LEDs and VCSELs. It is also an optimal choice for cryogenic operation using 808 nm laser light.
Features
- RoHS compliant.
- Fully isolated power over fiber (PoF) solution that efficiently converts optical power to electrical power with a ~5V output.
- Qualified for an operating temperature range of –40°C to +85°C.
- The device is configured with an FC optical port for use with MM fibers with an NA ~ 0.22 and for any fiber core diameters (for example, from 40 μm to >400 μm).
- Easy heat-sink mounting for thermal management.
- Ideal output power range for regular-power applications, complementing Broadcom’s mediumpower power converters (for example, AFBRPOC306xx).
Applications
- Sensor applications: Provides isolated power for various sensors.
- Electric power utilities: Provides fully isolated power to protect sensor devices.
- Lightning: Protects key circuits.
- Biomedical and neuro-stimulation: Provides safe and tailored voltage and current sources.
- RF power electronic circuits: Reduces interference and ringing.
- Chemical plants: Uses power over fiber in corrosive areas where metal wires can be attacked.
- Avionics: Uses power over fiber instead of metal wires to reduce weight and EMI and to eliminate the risk of fire from sparks.
- Security: Triggers and powers sources unaffected by EMI-RFI.
