Toslink Audio Transmitter 850nm(TX) DLT 1811
1. Specific wavelength transmission:
850nm wavelength infrared light is used for signal transmission. This wavelength is suitable for multimode optical fiber, in which optical signals can be transmitted with low loss and dispersion, achieving high-speed data transmission, thereby ensuring high-quality transmission of audio signals.
2. Digital audio processing:
Supports a variety of digital audio formats, such as common stereo PCM, multi-channel surround sound, and Dolby Digital, DTS and other encoding formats, and can accurately convert the input digital audio electrical signals into optical signals for transmission.
3. Efficient photoelectric conversion:
The built-in photoelectric conversion element can efficiently convert electrical signals into optical signals, with high conversion efficiency and stability, ensuring the strength and quality of optical signals to achieve long-distance transmission.
4. Strong anti-interference ability:
Optical signal transmission is not affected by electromagnetic interference, such as WiFi signals, Bluetooth signals, and power supply noise. In complex electromagnetic environments, such as machine rooms, around stages, or in environments with multiple electronic devices in the home, it can stably transmit audio signals to ensure that the audio quality is not interfered with.
