Broadband telecom Project
Nov 04, 2021
Broadband telecommunications system: It is based on fiber optic cables and uses optoelectronics to deliver multiple high-end services such as telephone triple play, broadband Internet and TV to homes or businesses. Optical fiber communication is widely used as a medium for information transmission due to its unique anti-interference, light weight, and large capacity. However, it is the most economical and most effective to use the existing transmission lines to lay optical cables. Because optical fiber communication has the advantages of large capacity, long distance and resistance to electromagnetic interference, optical fiber communication is well adapted to the needs of today's power communication development. Especially the optical fiber composite overhead ground wire (OPGW), which combines the high mechanical, high conductivity and good corrosion resistance of the aluminum clad steel wire, effectively combines the power overhead ground wire with the communication optical fiber, so it is affected by the power system industry. Attached importance to, and gradually being promoted and used.

There are many architectures for fiber to the home, of which there are two main ones: one is a point-to-point topology, which uses an optical fiber from the central office to each user; the other is passive optical that uses a point-to-multipoint topology. Network (PON), the use of point-to-multipoint solutions can greatly reduce the number of optical transceivers and fiber consumption, and reduce the rack space required by the central office, which has cost advantages and has now become the mainstream.
