How to better understand 2.5G switches?

In recent years, various emerging scenarios have gradually emerged, and people have put forward higher requirements for network speed. Network communication-related technologies are developing rapidly. In addition to 5G in the mobile field, new features such as WiFi6 are rapidly popularizing in-home broadband scenarios. At the same time, high-speed broadband coverage is also expanding.

At the same time, many flagship network equipment have quietly been upgraded to 2.5G interfaces. Regarding this, there are two opposing voices.

– The 2.5G port is a cutting-edge technology. The Gigabit port can still meet the current mainstream needs. Consumers should not pay unnecessary costs.

– 2.5G is a rigid need. Gigabit ports are outdated and cannot meet the needs of Aeon in emerging scenarios. 2.5G should become the standard configuration of future flagship network equipment.

Why not, let’s take a look first, what is the 2.5G interface? The 2.5G port is a network interface with a rate of 2.5Gbps. The actual rate is usually calculated as 2500Mbps.

Converted into a value that we can better understand, it is about 312.5MB/s, which is the theoretical upper limit of the download or upload rate of Internet-connected devices in daily use.

In the early days, switches were usually divided into 100Mbps and Gigabit products, namely switches with 100Mbps ports and switches with 1000Mbps ports.

In recent years, it has become a trend for switches to transition from 100M products to Gigabit products. In wireless scenarios, it is not uncommon for mobile phones and computers that now support WiFi6 to run network speeds exceeding 2000Mbps. In this case, Gigabit ports are It is easy to become a bottleneck. The emergence of a 2.5Gbps network port has undoubtedly greatly increased the upper limit of network transmission rate.

With the 2.5G port, will the network speed soar?

Objectively speaking…the network speed provided by the 2.5G port can theoretically reach a maximum of 312.5MB/s, which is far beyond ordinary imagination.

However, based on the actual situation, it is very unlikely to achieve this speed. Switches or routers with 2.5G ports increase the upper limit of network speed. To have this speed, you must first have such a large bandwidth. Compared with Gigabit switches, the speed will be significantly improved.

However, the more practical value of the 2.5G port lies in the intranet!

WiFi6 has a lot of new technical advantages, which can bring a better network experience. For ordinary users, a WiFi6-supporting mobile phone paired with a WiFi6 router or AP can theoretically run a wireless network speed of more than 2,000 megabits. This is Probably the most intuitive experience upgrade.

When we move away from the external network and turn to the intranet transmission, we can find its huge use.

The intranet mentioned here is simply a local area network composed of multiple networking devices on a router and switch, which can transmit data to each other.

Even if we unplug the optical modem, it will not affect the operation of the intranet. And if the intranet needs to use a network speed of over 300MB/s, it is naturally a NAS.

NAS is a private network disk, and the bottleneck of file transfer rate is usually the interface and network card. I used a 100M switch to connect to the NAS before, and the stable speed of around 10MB/s made people anxious. But after switching to a Gigabit switch, the speed of copying large files soared to more than 100MB/s, and the experience has naturally improved. Quite a few.

What about changing to a 2.5G Ethernet switch? Internet speeds soar and experience doubles.

Judging from the trend of technological development, it may only be a matter of time before mainstream broadband breaks through Gigabit in the future. Extending the time horizon, even 10G network cards, and 10G broadband will become commonplace in the future.

To meet the needs of new scenarios, buy actmtech Ethernet switches and pair them with 2.5G NAS equipment to easily upgrade the whole-house network.
