Allows you to easily test the Integrated Wiring System

The test of the Integrated Wiring System is still quite common, So I studied the differences between the test of the six types of Integrated Wiring System and the cat5e. I would like to share with you here, hoping to help you. Facts have proved that wireless technology is not an alternative to cat5e. It is applicable to environments where mobility is critical, or where Cables cannot be laid between switches and NICs. However, for general office environments, which represents a vast majority of network applications, the most cost-effective medium is undoubtedly the cat5e UTP.

Each port uses an Ethernet (10 Mbps) system, including a switch, NIC, and fully-installed and Integrated Wiring System test:
◆ Cat5e UTP 100%
◆ Class 6 UTP 123%
◆ Cat5e UTP 100%

Network transformation environment #2
Next, we will further analyze the transformation cost of Mbps Ethernet, which is a typical transformation environment for many organizations. For all these organizations, the cost is very high.

In this environment, we have not investigated wireless technology because it cannot support Mbps data rate. In this analysis, we found that the difference between Category 5 and Category 6 options is the same as that between 10 Mbps Ethernet, because NIC and switch are identical. Currently, when purchasing any Ethernet NIC, they usually automatically sense 10/100 Mbps. In this analysis, we also considered multimode optical fiber, because it is a feasible Mbps Ethernet medium. Currently, 100 Base-SX (short wave length) and 100 Base-LX (long wavelength) NICs can be provided at any time at a low price.

The cost model I use is based on medium prices obtained from distributors and a wide range of online surveys. Although the costs of 100 Base-SX and 100 Base-lx nic have changed significantly, I am using medium prices for well-known brands. This model shows that the cost of optical fiber cables is almost four times that of cat5e cabling, and it is not the most cost-effective solution. However, if you select an optical NIC with a lower cost, the cost difference will be much smaller. If end users do not predict further transformation, the most cost-effective option is undoubtedly the Category 5. It provides sufficient performance to support this application.

Small companies are typical representatives of this environment. They have basic network facilities or relatively simple IT needs. The software systems it runs may include text processing, workbooks, inventory management, billing management, and document storage systems. Another possible scenario is that users with relatively short lease periods cannot foresee switching to over Mbps Ethernet during their stay. In this case, cat5e is still the most cost-effective choice.

Each port uses a Fast Ethernet (100 Mbps) system, including a switch, NIC, and fully-installed and Integrated Wiring System testing:
◆ Cat5e UTP 100%
◆ Class 6 UTP 123%
◆ Multimode fiber 376%

Network transformation environment #3
Next, we will compare the cost of switching to Gigabit Ethernet.
The strange thing is that our number shows that the cost model is completely different from the first two environments. In the first two environments, the cat5e option is the lowest cost option, and the cat5e option is the highest cost option in the current environment. The cost of single-mode optical fiber is lower than that of Category 5. The reason for this reversal is that the cost of using the Gigabit Ethernet NIC for cat5e cabling is very high.
The price I use in the comparison of Gigabit Ethernet active devices comes from a wide range of online search results. If you want to complete the comparison by yourself, a simple method is to enter the keyword 'gigabit Ethernet 'on any search engine, such as Altavista, Yahoo, or MSN to search. You will find thousands of products provided by manufacturers and retailers. The price difference is very large.

As mentioned above, I have used medium prices for well-known products. For the cat5e option, the medium price of the Gigabit Ethernet NIC we use is about $600. The cost of each component is similar to that of the switch on the other end, and the cost of the installed wiring device is negligible.

However, compared with the cat5e option, the cost of the cat5e option is 25% lower, even if the cat5e option is 10% lower. This is because these models are built using a different version of Gigabit Ethernet, called 1000 Base-TX. However, 1000 Base-TX is only a rough convention. In the cat5e version, Gigabit Ethernet is called the 1000 Base-T, a ieee standard that has been approved for nearly two years. According to estimates made by institutions that developed the technology, the cost of 1000 Base-TX is basically close, and it is said that the cost of active devices at both ends is at least 1000 lower than that of 30% Base-T equivalent devices. The difference between 1000 Base-TX and 1000 Base-T is that the former requires transmission over Cat 6 Cabling or better copper cables.

Surprisingly, multi-mode optical fiber is the second lowest cost of a Gigabit Ethernet system, which costs about 1000 less than the 20% Base-T model in cat5e, although the installed optical fiber cables are about five times the installed cat5e cabling. Multimode Optical Fiber active devices are divided into two models: the growth wavelength (LX) and the short wave length (SX. Our cost computing is based on a low-cost SC Model that operates at an 850nm wavelength. The cost difference here is also very large, but we calculate it at the medium price of well-known products.
Each port uses a Gigabit Ethernet (1000 Mbps) system, including a switch, NIC, and fully-installed and Integrated Wiring System testing:
◆ Cat5e UTP 100%
◆ Class 6 UTP 75% *
◆ Class 7 STP 89% *
◆ Multimode fiber 80%
◆ Single-Mode Optical Fiber 96%

Gigabit Ethernet Decision Making
Now we can make some decisions on our best network facilities solution. If the organization is large, a network transformation strategy using Gigabit Ethernet should be formulated. If the lease period of a building is long, the selection would be less simple. The cost of media types and network devices will become very important.

Let's take a look at three of these questions:
1. For large organizations, some employees may be "users with high application requirements ". In the short term and medium term, this must be switched to Gigabit Ethernet to the desktop. Therefore, end users must include Gigabit Ethernet in their plans when considering future spending. 1000 Base-TX is not listed yet, but will be listed around next year. If the company's high application demand users switch to Gigabit Ethernet within this time frame, the deployment cost of 1000 Base-TX on Cat 6 Cabling is low. Therefore, although the installation cost of cat6 cabling is about 40% higher than that of cat5 cabling, the deployment cost of Gigabit Ethernet will be quite low in the near future.

2. If the network transformation strategy includes Gigabit Ethernet, users will benefit from immediately installing Cat 6 cabling. Although many users currently only deploy 10/100 Mbps Ethernet, the low-cost 1000 Base-TX standard will facilitate the deployment of Gigabit Ethernet in the future.

3. If the company rents buildings for a long period of time, which may be 5 + 5 + 5 years, or uses its own buildings, the company may eventually switch to Gigabit Ethernet. Installing cat6 cabling now also helps deploy Gigabit Ethernet at a lower cost using 1000 Base-TX.

Undoubtedly, the cost of the 1000 Base-T source device will continue to decline over time, and the cost of the NIC and switch will be half of the current cost when the company turns to Gigabit Ethernet. This is correct and specifies when the company will switch to Gigabit Ethernet. This may indicate that the cost advantage of 1000 Base-TX over cat6 cabling will no longer apply.
However, the same rule related to price drops also applies to 1000 Base-TX. Over time, when the 1000Base-TX technology was adopted, its development cost had been compensated. In production, it had achieved economies of scale and increased competition, the price of the 1000 Base-TX device will decrease in a similar proportion, so it can produce the same price advantage as currently.

Comparison between 1000 Base-T and 1000 Base-TX
Now let's take a closer look at how Gigabit Ethernet works and the differences between 1000 Base-T and 1000 Base-TX.

1000 Base-T, as the standard approved by IEEE, has been used for nearly two years. Its term is IEEE 802.3ab. In essence, a 250 Mbps signal is divided into four Mbps blocks. Each block is transmitted through one of the four wire pairs in the cable. Both ends of the cable transmit signals simultaneously, forming a full duplex transmission. In this way, the devices at each end deploy the transceiver for each wire pair (the transmitter and receiver are integrated in one device ). Therefore, each 1000 Base-t nic has four transceiver.

By using a sound coding system called PAM55 pulse amplitude modulation), signals are transmitted along each line and the transmission center frequency is only 62.5 MHz. This explains why we can run a 100 Mbps data throughput test on the cat5e cabling system, and its rated bandwidth is only MHz.
