Background
With the development of information technology, people have increasingly high demands for telecommunication services represented by fixed telephone networks, television broadcast networks and Internet data networks, but repeated investment of different networks causes resource waste and management cost increase, and the rapid development based on the three-network integration technology promotes the improvement of access network performance; PON (passive optical network) is the most attractive technology for access networks, and has been in deep focus in the last few years, and some areas have been applied on a considerable scale, and the broadband and comprehensive access feature of PON is one of the important means for all-service operation of large operators, so that it has received widespread attention.

POE (Power Over Ethernet) refers to a technology for transmitting power through a network cable, and on the basis of not changing the network architecture of the existing product, the existing ethernet is used for simultaneously transmitting data and supplying power to an IP terminal device (such as an IP phone, a wireless AP, an IP camera, etc.) through the network cable. POE is also known as a local area network-based Power over LAN (PoL) or active ethernet (ACTIVE ETHERNET), sometimes also referred to as Power over ethernet. The technology utilizes the existing standard Ethernet cable to transmit data and power which meet the standard specification, and maintains the compatibility with the existing Ethernet system. A complete POE system includes two parts, a Power sourcing equipment (PSE, power Sourcing Equipment) and a Powered Device (PD).
At present, products with POE functions are realized in PON communication equipment, POE power supply protocol standard tests IEEE802.3AF, IEEE802.3AT, IEEE802.3 BT/60W products, ONU equipment with the POE power supply functions are required to carry out a series of product batch test/verification work before the products leave factories so as to ensure the quality of the products. In the test of POE exchanger products, a great amount of POE power carrying capacity and data flow capacity under various load states are required to be measured simultaneously. The conventional method is to adopt a standard PD chip to carry cement resistance to simulate PD load capacity so as to realize test fixture equipment. The device has limited functions and does not have/has a simple function of manually switching the power gear of the PD analog load; the PD simulation load power gear is realized through the serial-parallel connection of simple power cement resistors, and the problem that PD simulation power is inaccurate due to the device consistency difference of the cement resistors and resistance value drift caused by temperature rise after the PD simulation load works is not solved effectively, so that the test may not reach the expected condition and the test is judged to be qualified.

Detailed Description
It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.
Fig. 1 is a block diagram of a PON product testing system according to an embodiment of the present application, referring to fig. 1, a PON product testing apparatus may include a first conversion module 100, a first analog module 300, a second conversion module 200, a second analog module 400, a switching module 26, a detection module 500, and a main control module 14, where the first conversion module 100 is connected to a first POE port 101 of a device under test 1; the first analog module 300 is connected to the first conversion module 100; the second conversion module 200 is connected with the second POE port 102 of the device under test 1; the second analog module 400 is connected to the second conversion module 200; the switching module 26 connects the first converting module 100 and the second converting module 200; the detection module 500 is connected with the second simulation module 400; the main control module 14 is respectively connected with the switching module 26, the detection module 500, the first simulation module 300 and the second simulation module 400; specifically, the first conversion module 100 and the second conversion module 200 may be configured to convert the electrical signals of the first POE port 101 and the second POE port 102 into electrical signals, respectively; the switching module 26 may be configured to be turned on or off according to an instruction of the main control module 14 to obtain a first test unit and a second test unit, where the first test unit is configured to test one network port of the device under test 1 when the device under test 1 uses a first protocol, and the second test unit is configured to simultaneously test two network ports of the device under test 1 when the device under test 1 uses a second protocol; the detection module 500 may be configured to detect a measured power value of the first test unit or the second test unit load; the main control module 14 may be configured to determine the matching capability of the device under test 1 and the load according to the comparison result between the measured power value and the actual power value output by the device under test 1.
The device under test 1 may operate the IEEE 802.3af and IEEE 802.3at protocols, i.e. the second protocol, and may also operate the 802.3bt protocol, i.e. the first protocol. IEEE 802.3af and IEEE 802.3at are two different POE (Power over Ethernet ) standards, IEEE 802.3af and IEEE 802.3at define methods of transmitting power and data over ethernet cables, and IEEE 802.3af (POE) standards define the manner of communication and power distribution between a power sourcing equipment (PSE, power Sourcing Equipment) and a Powered Device (PD). The PSE of the IEEE 802.3af standard may be a network switching device such as a switch, router, hub, etc., while the PD may be a wireless Access Point (AP), IP phone, webcam, etc. The PSE output power of the IEEE 802.3af standard is no more than 15.4W at maximum, and devices with no more than 12.95W at maximum power consumption can be powered due to the loss of the transmission wire. The IEEE 802.3at (poe+) standard requires that devices above 12.95W be defined as Class 4, and can extend power levels to 25W or higher. IEEE 802.3at may output more than 2 times more power than 802.3af, and the output power per port may be more than 30W. The PD responds with a Class 4 Class current telling the PSE whether it can be supplied with the higher power specified by 802.3 at. The device under test 1 operating in the IEEE 802.3bt protocol is the device under test 1. The IEEE 802.3bt specification introduces four new high power PD classes (Class 5-8) to bring the total number of classes to 9. Class 5-8 is new to the POE standard and translates to PD power levels of 40.0W to 71W. 802.3bt may be backward compatible with 802.3at and 802.3af, and a lower power PD may be connected to a higher power PSE without any problems. The test device sets the power of the POE powered device PD, which is an important step for simulating different POE power supply scenarios.
Specifically, in the embodiment of the present application, the device under test 1 is a test Power Sourcing Equipment (PSE), and the first analog module 300 and the second analog module 400 are Powered Devices (PDs). The switching module 26 is used for selecting the first test unit and the second test unit according to the instruction of the main control module 14. After the first test unit and the second test unit are determined, the detection module 500 detects a measured power value of the load of the first test unit or the second test unit. The main control module 14 determines the matching capability of the device under test 1 and the load according to the comparison result of the measured power value and the actual power value output by the device under test 1. The actual power values may include power values that the device under test 1 may increase under different protocols and at different levels. The measured power value is a test power value outputted by the first analog module 300 or the second analog module 400 according to the command of the main control module 14, and the test power value can test whether the device 1 to be tested can provide a corresponding power value under different power values, and whether the power level of the test power value is the same as the power level provided by the device 1 to be tested, so as to determine the matching capability of the device 1 to be tested and the load.
