Network Tester

Network tester profile

Along with the network popularization and complicate, network rationally set up and normal operation become abnormal important, and ensure the normal operation of the network must be from two aspects. Firstly, the network construction quality directly influence network of subsequent used, so the construction quality nots allow to ignore, must strictly and authentication check, bud. Secondly, the network breakdown telecontrol crucial, directly affecting the network operation efficiency must pursue high efficiency, short time. Therefore network detection auxiliary equipment in the network construction and network maintenance work becomes more and more important.

Network tester is usually called professional network tester or network detector, is a kind of can detect the OSI model definition of the physical layer, data link layer, network layer operation condition of portable, video intelligent detection equipment, mainly is suitable for the LAN fault detection, maintenance and the comprehensive wiring construction, network of tester functions cover physical layer, data link layer and network layer. Network of tester use can drastically reduce the network administrator grate network fault time, may provide the comprehensive wiring construction personnel working efficiency, accelerate the progress of the projects and project quality.

Network tester classification

A, network according to the network transmission medium tester can be divided into the wireless network tester and cable network tester two kinds.

The wireless network tester

The wireless network tester is mainly directed against the wireless router and AP, can detect a wireless network in the grate terminal connected and wireless signal strength, which can effectively management network nodes, enhance the network security. This product technology is not mature yet, along with the wireless network promotion, wireless network tester will more and more get of network management attention, become a kind of important testing tools.

Cable network tester

Cable network of common transmission medium to include: twisted-pair cable, optical fiber and coaxial cables. Coaxial cable are becoming a rarity, commonly used is twisted-pair cable, optical fiber is the development direction of the network. Market on transmission medium to develop the network tester, divided into fiber network tester and twisted-pair cable network tester, fiber network tester is not common, so we say normally network tester mean twisted-pair cable network tester. Second, the function can be divided into network tester cable detector, multi-function network tester and network performance tester.

Cable detector

Cable tester is mainly based on the network media, including cable length detection, crosstalk attenuation, signal-to-noise ratio, the circuit diagram and cable specification, used for parameters such as integrated cabling construction.

Multiple web tester

Multiple web tester usually refers to the many kinds of test function integration together network detection equipment, such as integrated link recognition, cable search, cable diagnosis, scan sequence, the topological monitoring, Ping function, looking for port, the concepts behind POE detection, etc. Such because of its equipment complete function, application range, can be competent for network maintenance, network construction and cable diagnosis, etc.

Network performance tester

Network performance testing equipment of high-end equipment, the main features include network flow test, data interception, IP query, flow analysis etc, used for large network security area, industry products.

Three, network tester can be divided into the end-use network construction equipment and network maintenance equipment.

Network construction equipment

Network construction equipment mainly refers to the comprehensive network wiring construction used in equipment, emphasizing the product quality is excellent, the measurement data of accurate, can adapt to construction environment and data requirements.

Network maintenance equipment

Network maintenance equipment focused more on product function to be complete, multi-purpose, can solve the network the several problems. Normally, the construction equipment and maintain the equipment has no obvious boundaries, mainly is according to the specific conditions and requirements to choose.
