Culvert cables are not easy to bury and difficult to maintain. The problem can be solved by adopting the steel pipe protection and the reverse buckle of the cable trough.
Signals and cables pass through the culvert and cannot be dug deep and buried as usual. Therefore, the cables are exposed, which facilitates protection, but cannot receive good results. The cable trough and the cover plate are used to pro

My colleagues reported that the Local Area Network could not be mounted. After reading the past, they found that the prompt "the network cable is not plugged in". I suspect that it is not plugged in, plug in, restart, and reinstall the NIC Driver.
My colleague reported that the network cable could be connected to the LAN using a laptop. After
verify the connectivity between each pin end and end of the cable link and check the winding problem. Any wrong wiring format, such as open circuit, short circuit, cross-connection, reverse connection, and string winding, should be able to be detected.
Attenuation is another important parameter for determining the performance of the cabling system. Any electronic signal from the signal source will cause energy loss during transmission, which is no ex

Scroll Mandrel must be used for field testing of Multimode Optical Cables according to U. S. TIA/EIA-568B standards ). It can be used to verify whether the 62.5 m and 50 m Multimode Optical Cables support Gigabit or even 10-Gigabit Ethernet networks by using a common LED light source with a wide scattering area.
High-level and low-level models
Multi-mode optical fiber cables contain multiple optical paths at the same time. Some of these paths are in the "low-level" mode in the center of the opti
Regardless of the final minimum copper platform, the complexity of the encoding system is a major obstacle for source equipment manufacturers. For cable and connector personnel and physical layer equipment installers, the question is more about what restrictions will this bring to the cabling facilities and what installation and test parameters will be required.
The Working Group has made a lot of discussions to solve the problem of external crosstalk
We know that the cable is the basis of the network, if you do not well identify the use of the cable, you will not become a qualified engineer.The BNC cable is the copper shaft cable that we use for CCTV, which is used today as a signal input/output probe in an oscilloscope, although the appearance and the traditional
Rules for making cable
Heuristic to think of the last year now do network maintenance day, every day line, pinch line, sometimes a day pinch more than 100 network cable. Based on the discovery that many of the computer-born small partners are unfamiliar with the network cable, the following roughly literacy.

In the construction of digital community, the choice of cable is one of the most important links. At present, several schemes are: 1, twisted pair, 2 coaxial cable, 3, optical fiber. From the practical application, because the price factor of twisted-pair cable has advantages over the latter two kinds of cable, but bec
1, the production of network cable, the first is to prepare materials, tools, etc., we need materials, tools have a suitable length of twisted pair, a number of RJ45 crystal Head, a twisted pair of wire crimping pliers, twisted pair tester;
2, twisted-pair connection method has two kinds: normal connection and cross connection, the normal connection uses is the international Eia/tia 568B Standard, but the cross connection uses is the inte

The UTP and unshielded FTP for category 5 and Category 6 copper cables have already reached a consensus in the industry. After the promulgation of the 10GBase-T standard, the battle for shielding and unblocking 10g copper cables is now in front of us. When more and more 10g copper cable products are available and more mature, are they shielded or unshielded?
Debate stems from out-of-Line crosstalk
Before the promulgation of the 10GBase-T standard, IEE
