Description
Technical field
The invention belongs to optoelectronic communication technical fields more particularly to a kind of for testing with multiple ethernet ports
The system of ONU radiation-emitting.
Background technique
For ONU optical network unit as terminal called equipment, application is more and more extensive.There is one kind to have multiple (4 in ONU
More than a, sometime up to 24 mouthfuls) equipment of ethernet port, Ethernet multiport, which is encountered, in radiation-emitting RE test draws half
The difficulty of anechoic chamber, since input and output filtering requirements in darkroom are high, common EMC semi-anechoic chamber is not provided with so much
Ethernet port can not all be drawn darkroom by ethernet port, if moving into darkroom flow device etc. is beaten, and will cause various tired
It disturbs, the radiation for especially beating flow device itself may not be able to be coordinated with the standard of equipment under test, the Ethernet multiport on ONU
It is connected to and draws beating on flow device outside an ethernet port to darkroom after the interchanger of subtest again, equally there is interchanger
Radiation-emitting and ONU uncoordinated problem, while test is not stringent enough in this way.
Summary of the invention
It is a kind of for testing with multiple Ethernets it is an object of the invention in view of the above shortcomings of the prior art, provide
The system of the ONU radiation-emitting of port.
To solve the above problems, the technical solution used in the present invention is:
A kind of system for testing the ONU radiation-emitting with multiple ethernet ports, including it is located at semi-anechoic chamber
Interior tested ONU and accompany and survey ONU, and OLT outside semi-anechoic chamber and beat flow device, the tested ONU it is multiple with
Too net port passes through cable respectively and is connected with the ethernet port for surveying ONU is accompanied, the tested ONU and the optical fiber extraction for accompanying survey ONU
The interface board of OLT is connected to after semi-anechoic chamber, the first line of a couplet optical port of the OLT, which is connected to, beats flow device.
Further technical solution be further include PD load board, it is negative that the ethernet port of the tested ONU is connected to PD
The too net port accompanied and survey ONU is connected to behind the port of support plate.
Further technical solution is that the tested ONU has eight ethernet ports, described that survey ONU is accompanied also to have
Eight ethernet ports, the PD load board are also eight.
Further technical solution is that the ethernet port is the port GE.
Further technical solution is that the flow device of beating is BigTao series of tests instrument.
The beneficial effects of adopting the technical scheme are that the configuration of the present invention is simple, be suitable for having it is multiple with
The ONU equipment for netting very much port, can be convenient operation, the authentic and valid radiation-emitting for testing out tested ONU.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the embodiment of the present invention 1；
Fig. 2 is the structural schematic diagram of the embodiment of the present invention 2.
In figure: 1, being tested ONU；2, it accompanies and surveys ONU；3,OLT；4, flow device is beaten；5, PD load board.
Specific embodiment
Embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples.Following embodiment is used for
Illustrate the present invention, but cannot be used to limit the scope of the invention.
Embodiment 1: a kind of system for testing the ONU radiation-emitting with multiple ethernet ports as shown in Figure 1,
It including the tested ONU1 being located in semi-anechoic chamber and accompanies and surveys ONU2, and OLT3 outside semi-anechoic chamber and beat flow device
Eight ethernet ports of 4, the tested ONU1 pass through cable respectively and are connected with eight ethernet ports for surveying ONU2 are accompanied, described
It is tested ONU1 and is connected to the interface board of OLT3, the first line of a couplet optical port of the OLT3 after accompanying the optical fiber for surveying ONU2 to draw semi-anechoic chamber
Dozen flow device 4 is connected to carry out playing flow point analysis.In the present embodiment, the tested ONU1 and accompany survey ONU2 optical fiber draw respectively
Darkroom is connected to two channels single fiber WDM of the PON passive optical network interface board of OLT3 (optical line terminal), on two of OLT3
Connection Ethernet double-fiber optical port is connected to dozen flow device 4 and carries out playing flow point analysis.The ethernet port is the port GE.The stream of beating is set
Standby 4 be BigTao series of tests instrument.It is two of same model device because being tested ONU1 in semi-anechoic chamber and accompanying survey ONU2
Individual both also is from equipment itself, not will cause erroneous judgement even if having exceeded in test process.
Embodiment 2: as shown in Fig. 2, itself the difference from embodiment 1 is that: further include PD load board 5, the tested ONU1
Ethernet port be connected to the too net port for being connected to behind the port of PD load board 5 and accompanying and surveying ONU2.PD load board 5 is for testing
Whether the PSE function of supplying power for demonstrate,proving ONU is normal, is applicable in the ONU with PSE function.
Finally, it should be noted that the above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations；Although
Present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that: it still may be used
To modify to technical solution documented by previous embodiment or equivalent replacement of some of the technical features；And
These are modified or replaceed, the spirit and model of technical solution of the embodiment of the present invention that it does not separate the essence of the corresponding technical solution
It encloses.
