Embodiment Construction

[0024] In order to make the above-mentioned features and advantages of the present invention more comprehensible, the following specific embodiments are described in detail with reference to the accompanying drawings.

[0025] The present invention designs a multi-standard digital optical fiber five-category line distribution system, which includes the following parts:

[0026] (1) After the BS interface of the near-end access unit of the multi-standard digital optical fiber distribution system is coupled with downlink radio frequency signals from multiple base stations (or remote base station systems) of different systems, it enters into a circuit that contains multiple different standard radio frequency circuits. The near-end integrated module is then filtered by the dielectric duplexer of the respective standard, the low-noise amplification of the downlink low-noise amplifier circuit, and the down-conversion circuit of the down-conversion circuit is down-converted to the down-...

Abstract

The invention relates to a multi-system digital optical fiber category 5 cable distribution system which is characterized by being composed of a near-end access unit part, an expansion unit part and a far-end cover unit part. The near-end access unit part, the expansion unit part and the far-end cover unit part form an up link and a down link of the system. The multi-system digital optical fiber category 5 cable distribution system is high in integration level. Low-noise circuits, frequency conversion circuits and amplifying circuits of the near-end access unit part, the expansion unit part, the far-end cover unit part and the like are all in an integration module design thought, and therefore the multi-system digital optical fiber category 5 cable distribution system is smaller in size, stronger in reliability and more beneficial for installation and use of practical projects.

Description

technical field [0001] The present invention relates to wireless communication equipment, especially a multi-standard digital optical fiber five-category line distribution system, which is suitable for solving the problems of difficult wireless signal access and property coordination. The system does not need to redeploy cables and can directly use resident network resources 1. User resources are used for cell signal coverage, and remote power supply can be used to solve the problem of user terminal power access. One system can complete the signal transmission coverage of multiple standards, realize the wireless voice and data coverage shared by multiple systems, and overcome the problems of large interference and repeated investment of operators in the traditional mobile phone signal coverage method. Background technique [0002] Domestic personal mobile communication operators have always attached great importance to the network construction of indoor coverage, and have bu...
