An LTE dual-channel optical fiber remote home coverage system

Abstract

The invention relates to an LTE dual-channel fiber remote household coverage system. The system comprises a near-end unit, an expansion unit and a far-end unit which are successively connected, wherein the near-end unit comprises a diplexer 1, a diplexer 2, a laser 1, a laser 2, an optical wavelength division multiplexer 1 and an optical demultiplexer 1; the expansion unit comprises an optical wavelength division multiplexer 2 and an optical demultiplexer 2; and the far-end unit comprises an optical wavelength division multiplexer 3, a laser 3, a laser 4, a power amplifier low-noise integrated module 1, a power amplifier low-noise integrated module 2, a diplexer 3 and a diplexer 4. The LTE dual-channel fiber remote household coverage system can solve the problems of low LTE dual-channel signal indoor coverage, ping-pong effect, pilot frequency pollution and the like and improves the perception of users.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to an LTE dual-channel optical fiber remote home coverage system. Background technique [0002] Operators adopt the strategy of fiber-in and copper-out. Existing communities, hotels, and guesthouses have broadband signals, and have basically adopted fiber-to-the-home to achieve xPON signal home coverage; the country is implementing "Broadband China", using fiber-to-the-home to realize xPON The signal home coverage method will be promoted on a large scale, but the traditional indoor distribution system does not have home coverage, and the antennas are all at the door of the house. When the LTE dual-channel signal passes through the wall, the attenuation is serious, resulting in the same field strength between the indoor signal and the external signal. Large, resulting in ping-pong effect and pilot pollution, seriously affecting the user's perception. Contents of the ...

Problems solved by technology

[0003] In view of this, the purpose of the present invention is to propose a LTE dual-channel optical fiber remote home coverage system, which uses secondary optical fiber remote, and the primary optical fiber remote solves the problem of different sites for LTE dual-channel signals and xPON signals. Then use the original home optical fiber of xPON signal to transmit LTE dual-channel signal and xPON signal at the same time, realize the home coverage of LTE dual-channel signal and xPON signal at the same time, solve the problem of indoor weak coverage, ping-pong effect and pilot pollution of LTE dual-channel signal problems, improve user perception
