What is the complete process of optical fiber upgrade in Xi 'an Telecom broadband community?

Generally, upgrading optical fiber in a telecom community means that when the number of residents in the community reaches a certain level, or local residents are within the scope of the optical fiber transformation plan, they can upgrade optical fiber without going through the application and provision procedures for the community.

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.

Optical fiber is one of the most ideal transmission media in broadband network, which has the characteristics of large transmission capacity, good transmission quality, low 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.
