What are the requirements for fiber optic transformation in residential areas?

1, optical fiber reconstruction requires rewiring. The original adsl directly used the telephone line at home, but now it is necessary to pull the optical fiber from the radio and television box to the home.

As for the wiring, it depends on the specific situation. If you can take the concealed pipe, the staff will take the concealed pipe, but some concealed pipes have their own defects and cannot be used for extra wiring, so you may need to re-thread.

3, the optical upgrade does not need to change the router, but it needs to change the modern and switch to the photoelectric cat.

4. Don't worry if you need to re-thread. Generally, I will discuss with my family and get permission before threading.

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.

5. 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.

6. The difference between fiber-optic broadband and ADSL access mode is that ADSL is the transmission of electrical signals, while fiber-optic broadband is the transmission of optical signals.

7. Optical fiber access is an access network with optical fiber as the transmission medium. Technically, optical fiber access networks can be divided into two categories: active optical networks (AON) and passive optical networks (PON). Active optical networks can be divided into AON based on SDH and AON based on PDH. Passive optical networks can be divided into narrowband PON and broadband PON.

8. Because the transmission medium used by optical fiber access network is optical fiber, according to the penetration degree of optical fiber to user groups, optical fiber access network can be divided into FTTC (fiber to the roadside), FTTZ (fiber to the community), FTTB (fiber to the building), FTTO (fiber to the office) and FTTH (fiber to the home), which are collectively called FTTx. FTTx is not a specific access technology, but the promotion degree or use strategy of optical fiber in access network.
