The Digital Optical Audio Cable product tells you that optical fiber connections can achieve electrical isolation, prevent digital noise from being transmitted through the ground wire, and help improve the signal-to-noise ratio of the DAC. However, since it needs a light emitting port and a receiving port, and the photoelectric conversion of these two ports requires photodiodes, there can be no close contact between the optical fiber and the photodiode, which will produce digital jitter-like distortion, and this distortion is superimposed of. The Digital Optical Audio Cable product tells you that coupled with the distortion in the photoelectric conversion process, it is much worse than coaxial in terms of digital jitter. Therefore, now the optical fiber interface has gradually faded out of people's field of vision.

The Digital Optical Audio Cable product tells you that it is suitable for connecting Blu-ray players and CD players with optical fiber audio cables to power amplifiers or televisions (optical square ports).
The Digital Optical Audio Cable product tells you that you need to pay attention to 3 points when using optical fiber audio cables:
1. Do not bend the fiber optic cable to an angle less than 50 degrees to avoid damage to the fiber core;
2. Before use, remove the dust plug on the optical fiber plug and keep the optical fiber plug clean;
3. The Digital Optical Audio Cable product tells you that the optical fiber plug is directional. When using it, please make sure that the direction of the plug and the socket is the same before inserting it into the socket.
