The 2016 China Data Center Annual Forum, sponsored by the China Engineering Construction Standardization Association and jointly sponsored by the China Data Center Working Group (CDCC) and the Integrated Wiring Working Group, was held from November 15 ~ It was held on the 16 th at Beijing New Yunnan Holiday Hotel. The Forum unveiled China's top 10 Generic Cabling brands in 2016. As a trusted communication network supplier in the world, rosenberger onc
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
Industrial Ethernet cabling and fault Maintenance
The industrial environment is worse than the general environment. At least the vibration, moisture, and temperature are worse than the general environment. Industrial Ethernet requires more professional knowledge and practical experience. If you are installing or using an industrial Ethernet (Industrial Ethernet switch), you must understand the Five Points of cabl
It is recommended that enterprises consider the following five issues before switching to VoIP:
1. Is your network wiring qualified?
The level of enterprise internal network cabling is very important. We recommend that you use a CAT-5e (100 M) or CAT-6 (1G) network cable for optimal voice quality because network speech requires additional bandwidth to improve voice quality. According to experience, most problems with many VoIP systems are caused by in
WiringMedium"Cabling,CableThe length of the remaining line in the distribution box must be the same, and the length should not be too long. It is best to group the remaining lines by grouping table, pull and tie them straight from the outlet of the cable trough, and the distance between the binding points is not greater than 50 cm. It should be noted that wire or hard power cord cannot be bound.

The wiring management software is flexible and scalable.
To analyze the requirements of cabling management software, we usually conduct surveys to understand possible device types, device properties, and hierarchical relationships, then, the information is designed into a database, and network data management is provided. However, this method has two problems:
(1) It takes a long time to constantly communicate with network
operation. Although in the actual project implementation process to choose the more advanced wiring scheme seems reasonable is not very good, but we suggest that we should consider the use of better quality products as far as possible. This will not embarrass your business in the face of higher network demand for a long time. Therefore, to ensure that the use of network cabling technology will not prematurely outdated, but also network
In the data center of Finance, Insurance, bond, government agency, etc., in order to ensure the speed of data calculation and the reliability of data storage and management, many core business applications are usually composed of high-performance server equipment such as standard or non-standard minicomputer, mainframe, etc. A separate SAN storage network is matched with these high-performance servers. In the implementation of this kind of equipment area wiring scheme, the wiring scheme implemen
When the 10G or even the million-gigabit copper becomes a hot spot, is it a bit outdated to talk about the 6 categories? Some might ask. But at present, most projects are using 6 types of systems is the fact that the user is reminded that the selection of 6 categories must choose the "whole" 6 categories.
The American Association of Communications Industry TIA has officially passed the 6-class wiring Standard (tia/eia-568b.2-1) as early as June 2002, and the standard is approved by ISO. Standar
General Wiring System Introduction
The Integrated cabling System (pds,premises distribution System) is designed for computer and communication wiring systems, which indicates that it can meet the requirements of various computers and communications. It includes:
1 analog and digital voice system;
2 High speed and low speed data system;
3 fax machines, graphics terminals, plotter, etc. need to transmit the image data

a gas-blown fiber system. After the cable was towed, the fiber was laid out and finally received a hardware device. Link loss can be determined, optical fiber can be put into use. The material cost of this system is lower than that of a gas-blown fiber system, except that the hardware is not needed elsewhere in the cable. The design is fixed, helps long-term maintenance, can move or change the system, no need to ask the installer to come back for a new upgrade. And can install Single-mode fiber
connected with it, so that the entire building grounding system composed of a cage-type pressure net. Good grounding can prevent the damage of weak current equipment by abrupt voltage shock, and reduce the influence of electromagnetic interference on the transmission rate of communication.

The star structure is the most common topological structure of the horizontal cabling subsystem,
Campus cabling is actually very simple: it meets the requirements of devices in the information, alarm, control, and other fields for physical layer transmission. In primary and secondary schools, technical schools, kindergartens, and other campuses, the campus wiring of colleges and universities is the most complex. The campus of a college is itself a small society, which contains almost all places in the city (of course, there are also, such as urba
At the plenary meeting of the Institute of Electrical and Electronics Engineers (IEEE) 802.3, IEEE approved a new generation of BASE-T interest solicitation request (CFI ).
The next generation of BASE-T will enter the stage of the standard development research team, the future direction of research and development is to balance the twisted pair copper cabling to reach at least 40g or even G Ethernet speed (GbE ), this approval is the first important m
