How to select a network cabling scheme

At present, in general, large and medium-sized network cabling system is generally used in the way of tendering, which puts forward how to review the cabling system scheme and how to choose the Final solution in many schemes. To address the above issues we have a point of view, only for the user's reference.

1. Choose a solution by bidding

Integrated wiring is a large building in the basic nervous system engineering, in general, it should at least guarantee the provision of 15 years to more than 25 years of use, in the guarantee period, no matter how much progress and development of science and technology, integrated wiring infrastructure and investment will not be eliminated. Therefore, the large and medium-sized network of integrated wiring engineering users should be given full attention. In view of the current comprehensive wiring market, the product is complex and diverse, so it should be solved by bidding. The bidding unit proposes its own network cabling scheme according to the bid, and then chooses the best scheme from a batch of schemes.

2. Selection of Bidding objects

When bidding, the unit of network construction should avoid the default contract unit as far as possible, and the technical level, economic strength and back-up guarantee ability of the bidding unit should be comprehensively measured. At present, the domestic integrated wiring market large and small companies, there are strong and weak, they in the economic strength, technical level and management level are very different. In the tender should avoid the "setter" phenomenon, to prevent the real construction unit hand, due to insufficient funds, it can only low-cost raw materials and simplify the process and other methods to achieve profits, engineering quality can not guarantee, bring endless trouble.

3. The choice of price

In terms of network cabling system engineering, users want to be in the economic investment of the most province, the fastest time, so that investors and unit superior praise. It is not necessarily advisable to haggle over the price or choose the lowest bidder. To know, excessive prices and price, is to sacrifice the quality of raw materials as a prerequisite to reduce the cost of construction process to achieve, construction units can not do a loss transaction. Therefore, the tender Unit should grasp the scale of the project cost, to choose a reasonable price, rather than the lowest price, in order to achieve the best value for money as the goal, this is the policy.

4. Product selection

Any project should involve product selection problem. Companies that provide the products are always trying to sell their products, saying their products are of the best quality. But the person responsible for product selection must pay attention to the product has the main components, secondary components, basic products, High-tech products, should fully understand the product performance and technical indicators.

In general, the European and American countries cabling products of excellent quality, but the price is high. In the case of strong financial resources, the choice of European and American products, quality assurance for the project is undoubtedly a favorable factor. However, it is also to prevent "parallel imports", resulting in the cost of a large price, the purchase is a fake things.

Relatively speaking, our country (including Taiwan, Hong Kong), South Korea and Singapore and other place's product price is lower, the quality is more stable, also has the fine goods, compares conforms to the Chinese market. However, in the market, shoddy products are emerging, for the low price, we must pay special attention to, especially vigilant, avoid fooled.

5. Choosing the right Technology

The technology of the integrated wiring system is developing continuously, and new technology is emerging constantly. What kind of technology should we choose? Our views are:

(1) Choose the applicable technology--according to the actual needs of the enterprise network development phase, to determine the wiring technology. Too high a technology, usually can cause high cost, maintenance difficulties, spare parts are not good to buy and so on.

(2) Choose mature and advanced technology-any technology has a development process. We recommend that the general user choose mature advanced technology, avoid blindly pursue the most advanced technology. Mature and advanced technology can provide both hardware and software technical support and assurance, to meet the user's current needs is enough. The most advanced technology is often accompanied by some deficiencies and at the same time, from the hardware point of view, the product has not been a long-term, widespread application of the test, there are congenitally deficient, and parts difficult to find, in the event of failure, may cause greater losses. From the software point of view, the mastery of new technology, digestion is likely to need a process, once there are problems, may not be able to solve, or a small problem solution also requires a very complex process, a lot of time and energy. In short, in addition to scientific research, national defense, higher education and other technical funds are strong, there are real application needs of users, generally do not blindly pursue the most advanced technology and products, the advanced technology to grasp the appropriate.

6. Selection of network Cabling system scheme

General tender units, will come up with their own wiring system solutions, emphasizing their best. Among the many options, how to choose the most suitable for the bidding unit needs of the plan? To sum up, we consider that the following points should be noted:

(1) Does the function meet the current needs of the user unit?

(2) Is there room for development and expansion?

(3) is the current investment still valid when the system is upgraded?

(4) Is the structure of the wiring system reasonable?

(5) Wiring system using the technology is advanced, mature?

(6) What is the quality of the selected devices? What's the price? How about price/performance?
