Future development trend of indoor cabling cable
To view:3  The release date:2019-12-19

As standardization organizations increasingly feel the need to adopt more common protocols in their work, the emergence of new technologies (such as enhanced category 5 and 6 cables, gigabit Ethernet, upgraded field testers, fireproof cables, etc.) has accelerated the pace of alliances between countries and international organizations. Standardization efforts have gained more participants, such as the international organization for standardization (ISO), and there has been a growing harmony in their cooperation, which has led to a greater understanding of ideas that have influenced technical specifications, including cables and components. For example, remote crosstalk and other phenomena have become important indicators of transmission performance.

云顶集团网址 We now have the telecommunications industry association (TIA), the electronics industry federation (EIA), and the cable standardization organizations of each country. In fact, the cable industry is now globalized, and based on this fact, a universal cable standard is coming soon, both from the perspective of suppliers and consumers. There will be a bloodbath before then, but hopefully the new standards will combine the merits of the various standards.

Gigabit Ethernet is increasingly used in some backbone networks, and its use in high-speed fiber and copper core cable backbone networks and private networks is growing rapidly. In addition, a new generation of Ethernet LAN protocols will move to the desktop for wider applications. This development has been facilitated by the increase in desktop processing power and speed, as well as the increased demand for quick response from users across networks.

Gigabit Ethernet (or called base - 1000 T on copper cable) theory has been widely installed in the cable system, including worldwide has been widely installed cable system, which includes all over the world have been widely used in high speed LAN cabling systems, namely: no shielding five types of twisted pair (UTP). Contrary to misleading claims in the market, gigabit Ethernet is designed to operate in the 100 MHZ frequency range. As the enhanced class 5 cable offers higher performance, it will be the best choice for future gigabit Ethernet installations.

云顶集团网址 Performance standards for class 6 UTP cables are expected to accelerate the widespread use of gigabit Ethernet in offices. "Compared to 10base-t, or even 100base-t, 1000base-t is a significant leap in network performance. Class 6 cables will be more suitable for l000base-t and 100base-t Ethernet. Since both TIA and ISO work closely with the ieee-8022.3 gigabit Ethernet committee, backwards compatibility with existing systems can be assured. Therefore, both 10base-t and 100base-t can run on a 1000base-t network.

云顶集团网址 The application of 5 kinds of wires in the home

Residential cables will undergo a huge development and the digital revolution will sweep through household electronics.

With the emergence of the Internet as a viable household medium and the gradual shift of the workplace from corporate offices to small home offices, residential cabling systems will evolve into high-volume, high-reliability cabling systems. Most home users can use the Internet for educational and entertainment purposes. By 2002, at least 100m people worldwide are expected to work from home.

Residential/home offices need to be connected to computers, printers, modems, Ethernet, integrated services digital network (ISDN), and require high-speed, broadband digital and communications transmission. In order to solve this problem, considering the cost and performance factors, 5 types of UTP cables and related equipment are obviously a reasonable choice. You can use 5 types of cables to create a virtual home LAN. Home users can use the bandwidth and enjoy any service on the LAN by simply plugging into any socket in the room. Today, many major cable manufacturers offer category 3, category 5, and coaxial cable to home users.

云顶集团网址 50/125 micron fiber

At present, many end users and manufacturers are turning to 50-125 micron multimode fibers with strong interest. In North America, the majority of users adopt the 62.5 micron fiber because it has been approved by the TIA and is sold in large quantities. Still, the 50 micron fiber has inherent advantages because it is technically superior to the 62.5 micron fiber and is cheaper.

云顶集团网址 The 62.5/125 micron fiber is optimized for use with leds. However, studies have shown that when other light sources (such as VCSEL and lumen surface laser emitters) are used with multimode fibers, the 62.5-125 micron fibers sometimes exhibit performance limitations that the 50-125 micron multimode fibers do not.

A growing number of 50 to 125 micron cables and supporting equipment are replacing or supplementing the 62.5/125 micron fiber in backbone horizontal cabling systems. The 50 micron fiber supports gigabit Ethernet and can transmit more than 500 meters (recommended value) for both long and short wavelength light sources. With the advent of low-voltage cable systems in the United States, traditional sound, video, and security systems will be incorporated into low-voltage cable structures. However, cable installers may find that the process will not be smooth because all of these manufacturers have different cultural backgrounds.
