Optical fiber distribution system and method realizing multipath access of different-address information sources

Abstract

The invention discloses an optical fiber distribution system realizing multipath access of different-address information sources. The optical fiber distribution system comprises a plurality of access units, at least one expansion unit respectively connected with each access unit, and at least one far-end unit connected with the expansion units, wherein the access units respectively support a plurality of communication standards of different service providers; in a down link, the access units respectively add corresponding communication standard labels to received radiofrequency signals and send the radiofrequency signals to each corresponding expansion unit through an optical fiber; the expansion units respectively carry out data processing on the received down optical signals sent by the plurality of access units supporting different service providers and send the optical signals to the each corresponding far-end unit through optical fibers; and the far-end units respectively process the received optical signals so as to convert the optical signals into radiofrequency signals of the corresponding communication standards, thereby enabling the radiofrequency signals to be sent to users. The invention further provides a communication method of the optical fiber distribution system realizing multipath access of different-address information sources.

Description

technical field [0001] The invention relates to the field of electronic equipment, in particular to an optical fiber distribution system and method for realizing multi-channel access of different address information sources. Background technique [0002] After years of long-term development in China's communication industry, a situation of 2G / 3G / 4G coexistence has gradually formed. Mobile communication signal transmission is transmitted through a certain frequency, and the frequencies and network standards owned by the three major operators are not the same. At present The formats already in use in the market are: [0003] China Mobile: GSM800, GSM1800, TD-SCDMA, TD-LTE; [0004] China Unicom: GSM800, GSM1800, WCDMA, TD-LTE, FDD-LTE; [0005] China Telecom: CDMA, CDMA2000, TD-LTE, FDD-LTE. [0006] The above does not include the excessive standards produced by various generations of communication technologies during the speech process. It is not difficult to see that ther...
