The YC series uncompressed digital optical transceiver developed and produced by Shenzhen Feiying Communication Technology Co., Ltd. adopts a fully digital optical transmission method, which simultaneously transmits over 100 channels of uncompressed video and stereo audio that meet national broadcasting standards, as well as over 100 channels of telephone or low-speed data streams (such as RS232, RS422, RS485, MAN code, etc.) on a single fiber optic cable, BIPHASE, By using advanced digital technologies such as high-speed DSP, FPGA, CPLD, etc., the use of switch signals and 10M/100M computing network data signals avoids the disadvantages of analog frequency modulation, phase modulation, amplitude modulation optical transceivers that are prone to intermodulation distortion interference, image and control data crosstalk, and product performance that is easily affected by environmental factors. All products use industrial grade chips, full surface mount, and are equipped with advanced technologies such as switch power supplies and anti electromagnetic radiation devices This ensures that the product can operate in various complex environments (such as outdoor environments with temperatures ranging from -35 to 70 ℃, power plants, etc.) with long-term and fault free connectivity The use of fully digital uncompressed transmission technology for video ensures that the video signal is transmitted remotely without damage, and guarantees that the baseband bandwidth of the restored video signal is greater than 8MHz. No matter how complex the optical transmission link conditions are, digital optical transceivers have the ability to ensure the transmission quality of audio and video signals.
