Optical fiber radio frequency transmission is a technology
Optical fiber radio frequency transmission is a technology that transmits radio frequency signals through optical fibers. Its structural principles mainly include the following aspects:
1. Basic principle of optical fiber transmission: An optical fiber is composed of a fiber core and a layer of cladding. The core of the optical fiber is made of high refractive index material, while the cladding is made of low refractive index material. Through this The structure can realize the total internal reflection of Industrial Router/Gateway light, so that the light is transmitted along the fiber core. The transmission characteristics of optical fiber include high bandwidth, long transmission distance, and small signal attenuation.
2. Radio frequency optical modulator: A radio frequency optical modulator is a device that converts radio frequency signals into optical signals. It can modulate radio frequency signals by changing the intensity, frequency or phase of optical signals, thereby converting radio frequency signals into optical signals.
3. Optical fiber transceiver: Optical fiber transceiver is a device that converts optical signals into electrical signals or converts electrical signals into optical signals. In the process of optical fiber transmission, it is necessary to convert optical signals into electrical signals for processing or convert electrical signals into optical signals for transmission. Optical fiber transceivers usually include components such as optical-to-electrical converters, amplifiers, and filters.
4. Fiber optic coupler: A fiber optic coupler is a device that connects multiple optical fibers together. It can realize the mixing and separation of multiple signals, and transmit multiple radio frequency signals through optical fibers. ethernet to rs485 converter To sum up, the structural principle of fiber optic radio frequency transmission is to transmit radio frequency signals through optical fibers, in which radio frequency optical modulators and optical fiber transceivers are key devices to realize the mutual conversion between optical signals and radio frequency signals, and fiber optic couplers can realize multiple signal transmission. mixing and separation.
