The communication network is developing to the age of all-optical networks, and the fiber access network will gradually replace the original copper access network. In the next few years, due to the development of high-speed data services and video services, the fiber construction cost has been reduced, with the increased competition among operators and the support of national policies, copper bandwidth has been challenged. Fiber access will enter a period of large-scale construction.
FTTx is the way to apply the optical fiber in the access layer network to make the optical fiber close to the user or even directly connected to the user. The optical fiber access network uses optical fiber as the transmission medium, and has the advantages of large transmission capacity, high transmission quality, high reliability, long transmission distance, and anti-electromagnetic interference. It is the development direction of fixed broadband access in the future. In recent years, people's needs have moved from simple voice communication to multimedia communication. With the rise of IPTV, HDTV, somatosensory games, and digital home services, traditional access methods can not meet the ever-increasing bandwidth requirements. The FTTx access rate can reaqch 20 Mbit/s to 100 Mbit/s. In the future, with the further improvement of the device technology, the bandwidth can be further increased, and it becomes an inevitable choice by its incomparable bandwidth advantage.
Among all the known FTTx implementation technologies, the Passive Optical Network (PON) technology has obvious advantages on manages operation and maintenance, bandwidth performance, integrated service , bandwidth allocation strategy, networking flexibility, and construction cost compared with other optical access technologies due to the optical fiber transmission medium, high access bandwidth and full-range passive optical transmission.
With years of technical accumulation and engineering practice in the field of communication networks, and unique idea on future optical communication systems, Junqian has released FTTX (FTT0, FTTH, FTTB+LAN, ...FTTCab+xDSL) system solutions based on communication networks physical connection devices for domestic and international communication network construction users, providing all-optical or optical copper combined wiring management products from the communication office end to the user's home or office.
