RF Over Fiber Analog/Digital Link 6GHz

SKU: RFOF

The RFOF is designed to form an RF link between two points using fiber optical cables. It features immunity to interferences, high bandwidth, low signal loss over long distances, low signal distortion, low power consumption, high reliability, and is easy to implement. It converts an input RF electrical 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 integrated with low noise amplifier (receiver). The transmitter and receiver pair form a transceiver that provides a transparent data transmission channel. They are available in 1310nm and 1550nm wavelengths, 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 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 rack mount box or ruggedized outdoor aluminum case. Temperature compensation is built into the transmitter.
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.
A pair of transmitter and receiver of the same wavelength is needed to form an RF link over a fiber. Two pairs of transmitter and receiver are needed to form a bidirectional RF link over a single fiber, in which either WDM fiber patch cables (1550nm and 1310nm) or circulator fiber patch cables (same wavelength) are used. We supply these 3-port cables that directly plug into the transmitters, receivers, and transmitting fiber line.
