Optical network unit and method for controlling power supply user terminal access thereof

Abstract

The invention discloses an optical network unit (ONU), wherein, a voltage detection module is added to the ONU, according to a detection result of the voltage detection module to a subscriber terminal power supply, an Ethernet transformer or a master control unit is controlled to realize subscriber terminal access port control; a diode is added to the ONU, multi-power supply load sharing is realized by using the characteristic of the diode selecting a branch with higher service voltage for connecting; power supply is transmitted from the subscriber terminal by the original Ethernet cable, so that supply voltage inputted from the subscriber terminal is converted to working voltage required by the ONU in a power supply module of the ONU, thereby realizing that all subscriber terminals connected with the ONU together supply electricity for the ONU. The invention also discloses a method that the ONU controls the access of the service subscriber terminal. With the application of the ONU and the control method thereof, all the subscriber terminals connected with the ONU together supply electricity for the ONU without fetching electricity from power supply in a passageway, thereby reducing power supply difficulty of the ONU and saving power supply construction cost.

Description

technical field [0001] The invention relates to an Ethernet passive optical network (EPON) technology, in particular to an optical network unit (ONU) and a method for controlling power supply user terminal access. Background technique [0002] Passive Optical Network (PON) has the characteristics of saving fiber resources and being transparent to network protocols, and has played an increasingly important role in optical access networks in recent years. At the same time, after 20 years of development, Ethernet (Ethernet) technology has almost completely dominated the local area network due to its simplicity, practicality and low price, and has been proved to be the best carrier for carrying IP data packets in fact. As the proportion of IP services in MAN and backbone transmission continues to rise, Ethernet is gradually penetrating into access networks, MANs and even backbone networks through improvements in transmission rate and manageability. The combination of Ethernet a...

Problems solved by technology

Since the current residential corridors adopt the method of buried wires, it is difficult to supply power to the ONU equipment in the corridors and buildings, and the construction cost of power supply for operators is high, and the way of obtaining power from the corridors also causes difficulties in settlement with the property.
