RF Over Fiber Analog/Digital Link System

SKU: RFOF

This series of RF Over Fiber Link transmits both analog and digital RF signals with a wide bandwidth of up to 40GHz over an optical fiber link with a distance of up to 20 km. It converts an input electrical RF signal into an optical signal via a high linearity DFB laser (transmitter) and re-converts the optical signal back into the RF signal at the other end of the fiber link via a high linearity photodiode and low noise amplifier (receiver). The transmitter and receiver pair form a transceiver that provides a transparent data transmission channel. They are available in wavelengths of 1310nm, 1490nm, and 1550nm, providing a versatile wavelength division multiplexing (WDM) capability. For example, bidirectional RF communication can be established with a single fiber link using two different wavelength transceivers and matching WDM cable adaptors. Another example is that three communication channels can be transmitted through a single fiber link by combining three transceivers of different wavelengths with our WDM cable adaptors. The module is packaged in a ruggedized aluminum case.
The RFOF modules are suitable for telecommunications, satellites, radio telescopes, distribution antennas, broadcasting audio and video, and timing synchronization. For example, point-to-point antennas can be connected from several meters to many kilometers away from the control room by fiber cables; Base stations can be connected through fiber to remote sector antennas; Satellite antennas can be connected through fiber cable to remote sites by RF over Fiber solutions.
