Embodiment Construction

[0035] In order to describe the technical content, achieved goals and effects of the present invention in detail, the following descriptions will be made in conjunction with the embodiments and accompanying drawings.

[0036] Glossary

[0037] xPON: As a new generation of optical fiber access technology, it has great advantages in anti-interference, bandwidth characteristics, access distance, maintenance and management, etc. Its application has attracted great attention from global operators, and xPON optical access technology is relatively mature Both EPON and GPON are composed of central office OLT, user ONU equipment and passive optical distribution network ODN. Among them, the ODN network and equipment are an important part of xPON integrated access, involving the establishment and application of a new optical fiber network, and the related ODN equipment and networking costs have become important factors restricting the application of xPON. At present, xPON technologies t...

Abstract

The invention relates to a remote home-entry covering method for an LTE dual-channel digital optical fiber. The remote home-entry covering method comprises an uplink signal transmission step and a downlink signal transmission step. A remote digital optical fiber for LTE dual-channel signals is realized through a near-end unit, the problem that LTE signals and xPON signals are not in the same station address is solved, packaging of the LTE signals and the xPON signals is realized through an extension unit and a far-end unit, home-entry covering is carried out by utilizing an original xPON home-entry optical fiber, and home-entry covering of the LTE dual-channel signals is realized under the condition of not influencing the xPON signals. The construction problems that a traditional indoor distributed system is long in construction time and difficult for property coordination are solved; home-entry covering is carried out on the LTE dual-channel signals through the original xPON home-entry optical fiber, and thus the problems, such as indoor weak covering, ping-pong effect and pilot frequency pollution, of indoor LTE network signals are solved, and the perception of a user is improved.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to an LTE dual-channel digital optical fiber remote home coverage method. Background technique [0002] With the rapid development of optical fiber technology, communication operators have also adopted the strategy of "light into copper and back out" in communication equipment. Existing communities, hotels, and guesthouses have broadband signals, and have basically adopted FTTH to realize xPON signal home coverage; the country is promoting "Broadband China", and the use of FTTH to realize xPON signal home coverage will be promoted on a large scale. However, the traditional indoor distribution system does not have home coverage, and the antennas are all at the door of the house. The LTE dual-channel signal is severely attenuated when passing through the wall, resulting in the same field strength between the indoor signal and the external signal, resulting in ping-pong ...
