Optical fiber distribution system and method for realizing multi-channel different address source access

Abstract

The invention discloses an optical fiber distribution system for realizing the access of multi-channel heterogeneous information sources, which comprises a master access unit, a plurality of slave access units respectively connected to the master access unit, and a plurality of slave access units connected to the master access unit. at least one extension unit, and at least one remote unit connected to the extension unit, wherein, the main access unit and each of the access units respectively support multiple communication systems of different operators; in the downlink Each of the slave access units sends the received radio frequency signal to the main access unit via an optical fiber after adding a corresponding communication standard label; the main access unit adds the corresponding radio frequency signal to the received After the communication standard label is sent to each corresponding expansion unit together with the received optical signal from the slave access unit; each said expansion unit sends the received optical signal to the corresponding through optical fiber after data processing Each of the remote units; each of the remote units processes the received optical signal to convert it into a radio frequency signal of a corresponding communication standard for transmission to the user.

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 different address information source access. 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 there ar...
