Working Principle
An 820 nm AlGaAs LED converts electrical input current to optical power launched into multimode fiber. The LED is driven by the TTL/CMOS-compatible input through an internal driver circuit. The 820 nm wavelength matches low-cost silicon detectors and provides low attenuation in PMMA and glass multimode fiber.
Applications
- Industrial fieldbus fiber link
- Automotive MOST network
- Medical isolated link
- EMI-immune communication
