The RF Over Fiber (RFoF) Analog/Digital Link converts wideband RF signals into optical signals for long-distance transmission over single-mode fiber.
By leveraging the inherent advantages of optical fiber—low loss, immunity to EMI, and wide bandwidth—the system enables transparent RF transport with excellent noise and linearity performance.
This solution consists of a Transmitter (TX) and a Receiver (RX), forming a complete point-to-point RF optical link suitable for demanding communication and broadcast applications.
