RF Over Fiber Link

SKU: RFOF

This series of RF over Fiber Links is designed to transmit both analog and digital RF signals with a wide bandwidth of up to 40GHz over an optical fiber link spanning distances of up to 20 km. It operates by converting an input electrical RF signal into an optical signal using a high linearity DFB laser (transmitter) and subsequently re-converting the optical signal back into the RF signal at the opposite end of the fiber link using a high linearity photodiode and low noise amplifier (receiver). This transmitter and receiver pair forms a transceiver that offers a transparent data transmission channel. Fiber optical amplifiers and chromatic dispersion compensators are integrated into the system for long-distance links to ensure signal fidelity. These RF over Fiber Links are available in 1310nm, 1490nm, and 1550nm wavelengths, providing versatile wavelength division multiplexing (WDM) capabilities. For instance, bidirectional RF communication can be established using a single fiber link by employing two different wavelength transceivers and compatible WDM cable adapters. Additionally, three communication channels can be transmitted through a single fiber link by combining three transceivers of different wavelengths with our WDM cable adapters. The module is housed in a ruggedized aluminum case, ensuring durability and reliability in various operational environments.
