A system for testing ONU radiation emissions having a plurality of Ethernet ports

Abstract

The invention discloses a system for testing ONU radiation emission with a plurality of Ethernet ports. The system comprises a tested ONU and a test accompanying ONU which are located in a semi-anechoic chamber, and an OLT and a flow striking device which are located outside the semi-anechoic chamber. A plurality of Ethernet ports of the tested ONU are respectively connected with an Ethernet portof the accompanying tested ONU through network cables, optical fibers of the tested ONU and the accompanying tested ONU are led out of a semi-anechoic chamber and then are connected to an interface board of the OLT, and an uplink optical port of the OLT is connected to a flow striking device. The device is simple in structure, is suitable for ONU equipment with a plurality of Ethernet ports, is convenient to operate, and can truly and effectively test the radiation emission of the tested ONU.

Description

technical field [0001] The invention belongs to the technical field of optoelectronic communication, in particular to a system for testing radiation emission of an ONU with multiple Ethernet ports. Background technique [0002] As a terminal communication device, the ONU optical network unit is used more and more widely. In the ONU, there is a device with multiple (more than 4, sometimes up to 24) Ethernet ports. During the radiated emission RE test, it is difficult to lead out the half-wave anechoic chamber from the Ethernet multi-port, because the input and output filtering requirements of the anechoic chamber are high. , the usual EMC semi-anechoic chamber does not have so many Ethernet ports, and it is impossible to lead the Ethernet ports out of the darkroom. If the streaming equipment is moved into the darkroom, it will cause all kinds of troubles, especially the radiation of the streaming equipment itself may not be able to To coordinate with the standard of the equi...

In the ONU, there is a device with multiple (more than 4, sometimes up to 24) Ethernet ports. During the radiated emission RE test, it is difficult to lead out the half-wave anechoic chamber from the Ethernet multi-port, because the input and output filtering requirements of the anechoic chamber are high. , the usual EMC semi-anechoic chamber does not have so many Ethernet ports, and it is impossible to lead the Ethernet ports out of the darkroom. If the streaming equipment is moved into the darkroom, it will cause all kinds of troubles, especially the radiation of the streaming equipment itself may not be able to To coordinate with the standard of the equipment under test, connect the Ethernet multi-port on the ONU to the auxiliary test switch, and then lead out an Ethernet port to the streaming device outside the dark room. There is also the problem of inconsistency between the radiation emission of the switch and the ONU. At the same time, the test is not rigorous enough
