Optical fiber distribution system and method supporting multi-communication-standard access

Abstract

The invention discloses an optical fiber distribution system supporting multi-communication-standard access. The system comprises a plurality of access units, at least one expansion unit which is connected with each access unit, and at least one far-end unit which is connected with the expansion units, wherein the access units respectively support a plurality of communication standards of different service providers, and the far-end units respectively support the plurality of communication standards of the different service providers; in a down link, the expansion units respectively process received optical signals according to communication standard labels in the received optical signals and send the optical signals to the far-end units supporting the communication standards; in an up link, the expansion units respectively process the received optical signals and send the optical signals to each access unit; and each access unit filters out data of unsupported communication standards according to the communication standard labels in the received optical signals and converts the filtered signals into radiofrequency signals of the corresponding communication standards, thereby enabling the radiofrequency signals to be sent to corresponding 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 supporting multi-communication standard 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 are many standards in servi...
