solutions for broadband connections. For IEEE, the universal standard for Gigabit Ethernet is to be international, including its broad market potential, compatibility with other Ethernet standards, technical feasibility and economic viability. The goal of the research team is to translate these requirements into actual operational content, making it an official standard.

between manufacturers is poor.
In early 1985, the computer industry association (CCIA) proposed a proposal for building cabling system standardization. The American Association of Electronic Industry (EIA) and the American Telecommunications Industry Association (TIA) began to work on standardization.
In July 1991, ANSI/EIA/TIA568 was published as the telecommunications cabling

The maximum length of these cables in trunk and horizontal hub-to-desktop) Structured Cabling System applications is described in detail in the International Standard IS0/iecis11801.
4. Size Limit
Before determining the cable type, it is also important to check the available space for
foreseeable that, in the near future, category 6 cables will become the mainstream solutions for copper cabling. In the end, with the development of the network, the six types of Structured Cabling solutions, rather than the 5E class, will certainly be supported. It is hard to say the specific time when the six types of solutions provide support, but the technic

Since the birth of the concept of structured cabling, command signals, control signals, and communication signals have been centrally transmitted through a common
In the digital age, you and I will be able to cross the border of the region without leaving home, and go all over the world of information, relying on the ever-changing data transmission technology. A seemingly illusory, hard-to-touch technical concept is closely related to us. The key lies in the structured cabling network in which we are surrounded.Structured Cabling

In recent years, the wiring technology is changing with each passing day. Compared with a few years ago, the wiring of non-standard devices shown in 1 is believed to be not accepted by most users. In the field of wiring, various manufacturers ha
Almost all projects require performance verification tests on the cabling system after construction. At present, copper cable testing methods, instruments and testing standards have been widely used by practitioners. Compared with copper systems, the popularity of optical fiber testing is much lower. Many projects do not perform fiber link tests, or only use a VFL light source to verify the optical connection. Using VFL light source to test the connec
