Fiber optic extender is mainly composed of optical transmitter and optical receiver. The optical transmitter converts electrical signal into optical signal, transmits it to the optical receiver at the other end through optical fiber, and the optical receiver converts optical signal into electrical signal and transmits it to the receiving device. In addition, fiber optic extender can also realize bidirectional transmission of image and data signals through wavelength division multiplexing technology.
Technical types and application scenarios of fiber optic extender
There are many technical types of fiber optic extenders, including analog fiber optic extender and digital fiber optic extender. Analog fiber optic extender adopts PFM modulation technology and is suitable for scenes requiring high-quality image transmission, such as television broadcasting and film production industry. Digital fiber optic extender includes MPEGII compressed and non-compressed digital image fiber optic extender. The former is suitable for occasions with low real-time requirements, while the latter guarantees the transmission quality and real-time of video signals and is suitable for fields requiring high-quality and large-capacity transmission. .
The advantages of fiber optic extender include:
Long-distance transmission: The transmission distance can reach tens of kilometers or even hundreds of kilometers.
High speed: The transmission speed can reach hundreds of megabits per second.
Strong anti-interference ability: The signal will not be attenuated or distorted, suitable for long-distance, high-quality transmission needs.
High stability: Suitable for application scenarios that require stable data transmission.
