A RoF communication device includes a RF circuit board and an optical module. Radio over fiber transports RF signals via optical fiber, enabling low-loss distribution for wireless networks, radar systems, and radio astronomy applications. Radio frequency over fiber (RFoF), also known as radio over fiber (RoF), is a hybrid technology that combines wireless communication with. Radio over Fiber (RoF) is an analog transmission that uses RF signals to modulate light which is transmitted over a fiber-optic cable. At the receiving end, the RF energy is recovered. RoF technology has been widely used in avionics, distributed antennas, cellular telephones, satellite communications, and other fields.
