One hundred years ago, you won't hear anyone laying telephone lines at home. Fifty years later, the telephone line was laid out very common, but it was never heard of anyone who installed the TV cable at home. Today, all residential buildings have installed telephone lines and cable TV cables in advance. What will happen in the future? The future trend is structured cabling for home computer networks. In th

1. Introduction to return loss indicators Ripple loss is an important indicator of digital cable products. Ripple loss combines two kinds of reflection effects, including the deviation of nominal impedance such as 100 Ω and the influence of structure, used to characterize the performance of a link or channel. It is caused by the non-uniformity of the characteristic impedance of the cable length. It is caus

Rats are widely used in various regions of the world as a type of rodents with strong fertility and vitality. Because of their well-developed and constantly growing population, as a result, rats have the habit of keeping their teeth sharp by biting objects. The unique smell of plastic makes plastic a common biting object. Whether it's in the wild or in the human activity area, the mouse has a strong damage to the wire/cable jacket or insulation layer.

Ribbon cable A fiber optic cable that is machined by a plurality of single fiber fibers, which are colored, stacked into strips, and two times molded. There are two kinds of optical fiber, namely the encapsulation type and the side-viscosity type, the former can withstand transverse pressure, the latter thickness is thin. Each band can have 4, 8, 12 or 16 fiber. In-band fiber spacing is 0. 28mm (for 4, 8)

Method/Step: 1 Packing: Super 5 Type network cable marked with cat5e words should be 305 meters (1000 feet) per carton, marked with CAT5 is 5 class line, packaging is not 305.1-meter box may not be network cable. Line above the logo: regular manufacturers of the product logo on the label has length, do the project to facilitate the identification of 1-box line used how many meters, how many rice noodles l

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

1. FTTH development at home and abroad The narrow-sense FTTH cable refers to the further extension of fiber to the user side, ITU believes that FTTH from the fiber-optic end of the photoelectric converter to the user no more than 200 meters, thereby eliminating the need to install an electronic access system in the metal, but not excluding photoelectric converters and desktop terminals using unlimited systems, for commercial systems can also be calle

(1) You can replace a possible faulty network cable with a normal network cable that you are using. If the network connection to the XP system is normal after the replacement, the original cable is faulty. (2) If there is no replacement of the network cable, first of all, you can carefully check the network

With the increasing number of wireless applications in the world, the irony is that it is increasingly necessary to use wires and cables in high-speed environments. A senior system engineer named Carroll Wontrop from Danaher Motion in wooddell, Illinois, said: "wireless is a competitor, but in a habit, it may be difficult for users to perform conversions ". People are worried that wireless communication will be vulnerable to interference from other wireless communications. Therefore, design engi

The daily use of the computer at the same time some friends may encounter is on the internet or just turned on the computer when prompted network cable was unplugged, such a phenomenon makes people very disgusted, the general phenomenon is not the computer network is not connected to the network is always interrupted, so that users can not carry out normal network applications, then how to solve such a phenomenon? Let's first analyze how we can create

The installation of the LAN starts from the cable, which is the most basic part of the network. According to statistics, about 50% of the network failure and cable-related. It can be seen that the quality of cable itself and the quality of cable installation directly affect the healthy operation of the network. In addi

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

specific applications to test the quality of cable jackets. For details, see: CMP: Fill-level communication cable, which is the highest cable Safety Grade and has a perfect flame retardant capability with very low smoke and toxin emissions. According to UL's definition, a bundle of CMP cables must be self-extinguished when the fan is forced to burn in dense comb

Standard Organizations and manufacturers in North America and Europe have long been arguing over the selection and standards of the outer skin of Integrated cabling network data cables, just as they are still using FTP shielding products for UTP. Currently, North America, South America, Asia Pacific, and China all adopt the North America-based cable fire prevention standard UL and NEC (National Electrical Code ), in some parts of Europe, low halogen o

Maybe many people do not have a special understanding of the man optical cable line. Next we will introduce in detail the overall design and technical application of the man optical cable line. How to build a Metro optical fiber network? First, it should be based on the network structure of the man. Second, according to the construction idea of the man, the topology of the network should be flexible and cap
