Optical / RF Delay Lines

Fiber Optical Transmitter/Receiver 10MHz to 35GHz

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 an electro-optical modulator coupled with a 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 wavelengths 1550nm C-band, providing a versatile wavelength division multiplexing (WDM) capability.
