A passive optical network pon system carrying domestic LTE room distribution system

Abstract

The present invention describes a passive optical network PON system carrying a domestic LTE indoor distribution system, including OLT, ODN and ONT, the OLT communicates with the ONT through the ODN; the OLT integrates the multi-mode connection of the LTE indoor distribution system Incoming unit and multi-mode expansion unit, it is provided with: radio frequency feed-in unit sub-card, baseband feed-in unit sub-card and Femeto unit; Described ONT merges the multi-mode remote unit of LTE room distribution system, and it is provided with physical sub-card Card, the physical sub-card realizes the indoor coverage function. Due to the adoption of the above technology, the present invention utilizes the ODN fiber pre-laid by the mobile operator, and improves and upgrades the OLT equipment module and the ONT equipment module at the central office, thereby realizing the LTE indoor distribution coverage signal for home use. Finally, on the basis of realizing low-cost user broadband access, the LTE signal enhancement in the user's home is improved, and the deep coverage of 3G / 4G / 5G signals is realized.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a passive optical network PON system carrying a domestic LTE indoor distribution system combined with an LTE indoor distribution system on the basis of a mobile PON carrying home broadband system. Background technique [0002] At present, in the field of mobile communication, the system block diagram of PON (Passive Optical Network: Passive Optical Network) is as follows: figure 1 As shown, its optical distribution network does not contain any electronic devices and electronic power sources, and its system structure is mainly composed of the optical line terminal (OLT: Optical Line Terminal) of the central office, and the optical distribution network (ODN: Optical Line Terminal) containing passive optical devices. Distribution Network), optical network unit / optical network terminal (ONU / ONT: Optical Network Unit / Optical Network Terminal) at the user end, wher...
