After upgrading, how much faster is more GiG than 1G?

Recently, Nbase-T products (multi-Gigabit switches and wireless AP, etc. ) has been seen in the online market, but many people still don't know much about this technology. Today, let's take a look at the application of this technology and its products. Nbase-T technology is a brand-new network technology led by Nbase-T alliance. By defining a new Ethernet signal mode, it makes the existing twisted pair (Cat5E/Cat6) as long as 65,438+. Nbase-T can make the transmission speed of a large number of existing super Category 5 and Category 6 cables reach 2.5Gbps or 5Gbps, so that users can greatly improve their network speed with the highest cost performance and the lowest impact, and there is no need to replace cables on a large scale, thus saving considerable installation costs and avoiding the interruption of daily work. In this way, we can clearly understand how to evaluate its wiring topology and infrastructure, so as to determine how to make the best use of the advantages of Nbase-T solution, solve the rate limitation for enterprises that have implemented Cat5E/Cat6 cables, and improve the performance of enterprise networks.

I. Application of Nbase-T technology

Transmission distance of 1 and CAT5E/CAT6 copper cables

The data comes from a third party. In the global market, the cables using Cat5e and Cat6 still account for the vast majority in the laid wiring system, and the two together account for about 75%, which is very large. If the 10Gbps network cannot be upgraded at one time, many problems will be involved, such as the need to replace the new standard 10G copper cable, the need to rebuild it, and the need to suspend daily network work. This will directly affect the normal office of enterprises and increase more costs.

Therefore, the speed cannot be increased to 10Gbps on the cable of Cat5e and Cat6. To break through the limit of 1Gbps, Nbase-T is the best solution, which can be upgraded to 2.5Gbps or 5Gbps.

The transmission distance of Nbase-T on CAT5E/CAT6 copper cable is shown in the following table:

2. The application of NBASE-T in WIFI.

With the development of wireless technology, especially after the emergence of 802. 1 1AC technology, the wireless network rate has exceeded the bandwidth of 1Gbps, and the theoretical value can reach more than 6Gbps in WAVE2. Therefore, in the implementation of applications, we often encounter the following network architecture problems (as shown in the figure below), and wireless AP and switch still transmit at the traditional rate of 1Gbps.

One of the main applications of Nbase-T is that with the transition of the new generation 802.1acwave2 access point technology and the development of the next generation 802.1ad/ax wireless, 2.5G or 5G ports will be widely popularized in the next few years, because this technology can use the existing Cat5E/Cat6 for enterprises.

As shown in the following figure: With the original infrastructure unchanged, Nbase-T technology scheme can be adopted to build a new generation wireless network scheme. The switch connects the multi-Gigabit switch and the multi-Gigabit wireless AP through the Cat5E/Cat6 network cable, which can increase the speed limit of 1Gbps, and the speed can be increased to 2.5Gbps or 5Gbps.

In the above solution, the multi-Gigabit switch M4200- 10MG-POE+ and the multi-Gigabit wireless AP WAC740 can be used together.

M4200 switch is a multi-Gigabit access, 10Gigabit uplink full network management switch, which also supports POE+ power supply. M4200 switch provides high-quality solutions for campus networks and medium-sized organizations, regardless of the application type 1G, 2.5G or 5G, including wireless access, IP video and unified communication.

WAC740 is a wireless access point supporting 802. 1 1ac Wave 2. 802. 1 1AC 4*4 antenna can provide a throughput of up to 3.2G (600M+2.6G) and is equipped with 1 Nbase-T 2.5G Ethernet RJ45 interface, 65438.

Second, the speed test of Nbase-T switch under super-Category 5 network cable.

Performance test of 1 and Nbase-T switches

Aiming at Nbase-T technology, this time we mainly use netware to test gigabit switching rate in practical application. We use Cat5E (Super Category 5 network cable) to test various rates (1Gbps, 2.5Gbps, 5Gbps) of multi-Gigabit switches, and compare the transmission rates of these rates on Cat5E cables.

Super Category 5 network cable:

Nbase-T products:

There are many models in the product line of Netware Nbase-T switch, such as M4200- 10GM-POE+, MS5 10TXPP, MS5 10TX, XS505M, XS508M, GS1/0mx. It can support 100M, 1G, 2.5G, 5G and 10G connections. This port automatically detects the required rate for connecting devices and provides sufficient rate.

Comparison of test results:

According to the above rate test results, the Nbase-T switch product of Netware eliminated the bottleneck of 1Gbps on the original Cat5E/Cat6 network line, making it break through the rate of 1Gbps and reach the rates of 2.5Gbps and 5Gbps. Therefore, when the original cabling system is Cat5E/Cat6 infrastructure, if enterprises need to increase the speed of 1G, the application of multi-gigabit switches is a very suitable and economical solution.

Note: this test uses the application in the actual environment, and does not use a special rate test tool, so the actual rate of the measured data is biased.

Third, the application of multi-Gigabit switches.

Nbase-T technology helps to make better use of the original infrastructure and will be widely used in all walks of life in practical application. The main applications are not only multi-Gigabit switches and multi-Gigabit wireless AP with the above interfaces, but also NAS devices, game machines, servers and other devices.

Application of 1, Gigabit Switch in New Era Star Hotels

In addition to the wired and wireless network connection of the most basic rooms in the hotel, the TV system, telephone system, monitoring system and access control system are gradually IP-based, becoming a part of the hotel network system. Nowadays, the world has gradually entered the Internet of Things era, and the information application of hotels will inevitably enter the Internet of Things era. Speaking of which, I suddenly feel so sorry for the information manager of the hotel.

But no matter how high the information application is, it can't be played without a high-quality basic network architecture. Especially with the increasing demand for IPTV, Internet of Things applications and other video applications, higher requirements are put forward for the hotel's basic network architecture. In the Internet of Things era, the number of networked devices has increased several times. Coupled with the traffic brought by various video applications, the hotel's basic network is under great pressure.

Due to historical reasons, the basic network of most hotels is still in the stage of 100 megabits access to Gigabit uplink, and the wiring system is mainly over five types of wiring systems. For such a network infrastructure, I really feel helpless to realize rich Internet of Things applications and video applications. Netgear has recently launched several cost-effective five-speed switch products, which is the gospel of network upgrade of star-rated hotels.

2. Promote the application of a new generation of Gigabit switches.

After the "Digital Campus" is completed, the original wired network needs to meet the requirements of high bandwidth, high stability, high security and high reliability. In the application of various functions such as "Banbantong", "e-bag" and "multimedia classroom" in general education, the network support platform seamlessly connected with the terminal at high speed is a basic and comprehensive project, which can provide digital resources and management platform for learning and also a platform for communication between teachers and students.

Therefore, this network support platform must be a highly stable, reliable and reliable basic network architecture. In order to improve the performance of the original CAT5E wiring system, NETGEAR five-speed switch products are needed to meet the requirements of the general education industry, so that the bandwidth of the original backbone network and the high-speed wireless AP can be increased to 2.5G or 5G networks.
