What interface is optical?

Optical is an optical fiber interface; the optical fiber interface is an audio input method that connects optical fiber for audio transmission. Optical fiber transmission can achieve electrical isolation and prevent digital noise from being transmitted through the ground wire, which is beneficial to improving the signal-to-noise ratio of the DAC. If there are many optical fiber interfaces, you can choose the interface and optical fiber of the connecting cable according to the interface type.

What is the optical interface?

Optical optical fiber interface input.

Optical optical fiber interface is an audio output method that connects optical fiber cables for audio transmission. Currently, most DVD players and Blu-ray players have optical fiber output terminals, and the optical fiber output on the TV can be connected Home theater system outputs better sound quality. Optical fiber transmission can achieve electrical isolation and prevent digital noise from being transmitted through the ground wire, which is beneficial to improving the signal-to-noise ratio of the DAC. Currently, not many fiber optic outputs are used, and only some high-end home theater players are using fiber optic interfaces.

There are different types of fiber interfaces to adapt to different network environments. Pictures of various interfaces are as follows:

optical is a fiber optic interface, where optical means fiber optic. However, you need to understand that there are many types of fiber optic interfaces on routers. , users need to select the interface and optical fiber of the connecting cable according to the interface type.
