Problems solved by technology

[0003] (1) Waste of resources: Operators separately purchase optical fiber equipment such as CDMA, GSM, DCS, WCDMA, TDSCDMA, etc.
This will lead to an increase in operating costs and construction difficulties, and problems such as redundant construction caused by operators building their own coverage systems will become more and more prominent
[0004] (2) Capacity: Some buildings such as supermarkets, conference centers, etc., due to the excessive user density, the noise at the bottom of the CDMA network users is greatly increased, and the GSM congestion is serious, resulting in limited capacity
[0005] (3) In terms of quality: due to frequency interference, pilot pollution, and ping-pong effects, the signal in the cell is unstable, the voice quality is difficult to guarantee, and even call drops occur

Abstract

The invention relates to a multi-system optical fiber access system for optical terminals, which includes a near-end computer, a remote computer, an optical fiber module, and an optical fiber cable. machine connection. Compared with the prior art, the present invention has the advantages of less useless signals, low cost, simple networking and the like.

Description

technical field [0001] The invention relates to an optical fiber access system of an optical terminal, in particular to a multi-system optical terminal optical fiber access system. Background technique [0002] The large-scale growth of mobile communication users makes the scale of the wireless network larger and larger, and the requirements for the quality of the network are also higher and higher. However, no matter what kind of wireless communication coverage area will produce weak signal areas or blind areas. Some remote areas, special places (tunnels, subways, large buildings, etc.) usually choose the economical and effective equipment of optical fiber repeater to solve the problem of signal coverage in these places. However, operators in the mobile market all strive to obtain good Customers will actively use a large number of indoor coverage system optimization work for the above-mentioned places. In order to compete for traffic volume and develop new traffic volume, ...
