Problems solved by technology

[0006] POI (Point of Interface, multi-network combination platform) can only solve the combination of several standard mobile communication signals; BBU (Baseband Unit, baseband resource pool / baseband shared resource pool / baseband pool / baseband unit)+RRU (Remote Radio Unit, remote radio frequency unit) The main problem is that the frequency band is narrow, and multi-network integration cannot be realized;
[0007] The main problem of the equipment system of LGC wireless equipment company in the United States is also the narrow frequency band, which cannot realize multi-network integration;
[0008] General traditional repeater relay (RFPA, Radio Frequency Power Amplifier, radio frequency power amplifier), including channel selection repeater, frequency band selection repeater, broadband repeater, etc., the main problem is also the narrow frequency band, Multi-network integration cannot be realized;

Abstract

The invention discloses a device for realizing the access of a plurality of information resources. The device comprises a downlink unit and an uplink unit, wherein the downlink unit is used for compositing an original data signal with each standard signal of mobile communication after modulating the original data signal, performing photoelectric conversion on a composite signal, and dividing the converted composite signal into at most eight selfsame composite optical signals for outputting; and the uplink unit is used for performing the photoelectric conversion on the at most eight received composite optical signals respectively, compositing the at most eight converted electric signals, separating each corresponding standard signal of the mobile communication and a data signal from a composite electric signal, recovering the data signal into the original data signal through demodulation, and sending the original data signal to respective information resource. The device realizes the access of the information resource of an overall transmission system, converts the information to be transmitted into spectral transmission, and meets the access requirement on the plurality of information resources.

Description

technical field [0001] The invention relates to the technical field of mobile communication access network, in particular to a device for realizing multiple information source access. Background technique [0002] In the current access network construction, in order to meet the requirements of multi-service signal access, such as Ethernet, CATV (CableTelevision, cable TV), CDMA, GSM and other signals, ultra-broadband, ultra-low power consumption, and low-cost optical fiber media have been adopted. Become a common goal pursued by the industry. However, due to the large differences in the transmission characteristics and node processing equipment of various service standard signals, it is difficult to transmit and process other service signals with any kind of transmission and node processing mechanism. Therefore, in the actual construction of the current network, independent network construction and parallel development are generally adopted. Various services monopolize one ...
