Description
Technical field
The utility model relates to POE network communication equipment field, particularly a kind of system of testing POE network communication equipment.
Background technology
In recent years, adjoint network and digital product universal, people are while to terminal transmission signals of communication such as such as IP telephone machine, wireless local network connecting point AP, web cameras, and the powerup issue of equipment also annoyings people.POE technology is exactly arise at the historic moment in this context, and it can ensure the normal operation of existing network while guaranteeing existing structureization wiring safety, reduces costs to greatest extent.
POE (Power Over Ethernet), Power over Ethernet (also referred to as feeder line power supply) is exactly that the Ethernet cable of transport communication grouping is simultaneously for the equipment be connected with Ethernet is powered.IEEE 802.3af and IEEE 802.3at standard transmit the newest standards specification of data and electrical power while of utilizing Ethernet transmission cable, and the compatibility maintained with existing Ethernet system and user, it adds the relevant criterion of directly being powered by netting twine on the basis of IEEE 802.3, it is the expansion of existing ethernet standard, also be an international standard about power distribution, electric power detection and control item in its clear stipulaties remote system, and routers, switch and hub by Ethernet cable to IP phone, the mode that the equipment such as safety system and Wireless LAN access point is powered specifies, market also produces non-standard POE power demands simultaneously, as the 24V supply network scheme etc. detected without the need to characteristic impedance.With the popularization of POE technology and the Internet flourish, have as POE switch, POE MDU and POE router etc. the network communication equipment that POE powers and arise, this kind equipment possesses Ethernet exchanging function and POE function of supplying power simultaneously.Be all its Ethernet exchanging function is separated with POE function of supplying power test to this kind equipment in the past, and not only ignored this series products quality risk that POE powers and Ethernet exchanging functional operation may be potential at the same time, also reduce production efficiency.
