Summary of the invention:
The purpose of this utility model be to provide a kind of simple in structure, cost is low is used for the optical node optical network unit of the full light mouth that optical fiber registers one's residence.
The utility model is that the technical scheme that adopts that achieves the above object is: a kind of optical node optical network unit of full light mouth, comprise housing, be provided with optical network unit, optical-electrical converter, power supply device in the housing and be arranged on last connecting port and second line of a couplet interface on the housing; Power supply device output port is connected to the power input mouth of optical network unit and the power input mouth of optical-electrical converter, the output of last connecting port is connected with the input of optical network unit, the output of optical network unit is connected with the input of optical-electrical converter, and the output of optical-electrical converter is connected with the input of second line of a couplet interface.
Further, described optical network unit is four electric port optical network units, and optical-electrical converter arranges four accordingly.
Further, described power supply device output 12V power supply to optical network unit, output 5V to optical-electrical converter.
Further, the input of the output of optical network unit and optical-electrical converter is the RJ45 interface.
Preferably, described optical-electrical converter is the SFP optical-electrical converter.
The utility model is simple in structure, goes for multiple optical fiber.Up is that the PON of monomode fiber inserts, and the longest 20KM that reaches descendingly can carry out optical fiber by POF and registers one's residence.
