The invention discloses a multi-service optical fiber distribution system, which includes multiple access units, at least one extension unit connected to each of the access units, and at least one remote unit connected to the extension unit, wherein, Each of the access units supports multiple communication systems of different operators, and each of the remote units supports multiple communication systems of different operators; in the downlink, each of the access units will The received radio frequency signal is added with a corresponding communication standard label and sent to each corresponding expansion unit through an optical fiber; each of the expansion units processes the received optical signal according to the communication standard label in the received optical signal Then send it to the remote unit supporting the communication standard; the remote unit processes the received optical signal to convert it into a radio frequency signal of the corresponding communication standard for transmission to the user.
Description
technical field [0001] The invention relates to the field of electronic equipment, in particular to a multi-service optical fiber distribution system and method. 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 service in the Chinese communication in...
