Are indoor mobile optical fibers and telecommunication cables common?

Mobile and telecom are not the same network operators, so it is impossible to be universal.

The biggest difference between wired broadband and optical fiber broadband is that optical fiber is the most ideal transmission medium in broadband network, which is characterized by large transmission capacity, good transmission quality, small loss and long relay distance. Optical fiber transmission adopts wavelength division multiplexing, that is, the data of multiple users in the cell are combined into high-speed signals through PON technology, and then optical signals with different wavelengths are modulated and transmitted in one optical fiber.

Wired broadband, also known as network cable and network cable, is a medium for transmitting information from one network device (such as a computer) to another, and is a basic component of the network.

Optical fiber broadband is to convert the data to be transmitted from electrical signals to optical signals for communication. The two ends of the optical fiber are respectively equipped with "optical cats" for signal conversion.
