Detailed Description
Embodiments of the present invention are described in further detail below with reference to the accompanying drawings and examples. The following examples are illustrative of the invention but are not intended to limit the scope of the invention.
Example 1: the system for testing ONU radiation emission with a plurality of Ethernet ports as shown in fig. 1 comprises a tested ONU1 and an accompanying ONU2 which are positioned in a half-wave dark room, and an OLT3 and a streaming device 4 which are positioned outside the half-wave dark room, wherein eight Ethernet ports of the tested ONU1 are respectively connected with eight Ethernet ports of the accompanying ONU2 through network cables, optical fibers of the tested ONU1 and the accompanying ONU2 are led out of the half-wave dark room and then are connected to an interface board of the OLT3, and an uplink optical port of the OLT3 is connected to the streaming device 4 for streaming analysis. In this embodiment, the optical fibers of the detected ONU1 and the accompanying ONU2 are respectively led out of two single-fiber WDM channels of a PON passive optical network interface board, where a darkroom is connected to an OLT3 (optical line terminal), and two upstream ethernet dual-fiber optical ports of the OLT3 are connected to a streaming device 4 for performing streaming analysis. The Ethernet port is a GE port. The flow device 4 is BigTao series of testers. Because the ONU1 to be tested and the ONU2 to be tested in the semi-anechoic chamber are two individuals of the same type of equipment, even if the standard is exceeded in the test process, the ONU is from the equipment itself, and misjudgment is not caused.
Example 2: as shown in fig. 2, it is different from embodiment 1 in that: the device also comprises a PD load board 5, wherein the Ethernet port of the ONU1 to be tested is connected to the port of the PD load board 5 and then is connected to the Ethernet port of the ONU2 to be tested. The PD load board 5 is used for verifying whether the PSE power supply function of the ONU is normal or not, and is applicable to the ONU with the PSE function.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present invention, and are not limiting; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present invention.
