100G switches are popular currently as 100G data rates have become the dominant network speed. This article will give a brief introduction to the development and current situation of 100G network switches and introduce a high-performance 10G/40G/100G stackable managed L3 switch developed by QSFPTEK.

With the increasing demand for higher data rates and bandwidth, 100G data rates have become the dominant network speed. The continued growth in 100G ethernet networks stimulated the development of 100G switches. This article first gives a comprehensive overview of 100G switches and introduces one high-performance 10G/40G/100G L3 stackable managed switch S7300-48X2Q4C developed by QSFPTEK, presenting its specifications and features. Finally giving a recommendation for matched optical module products.

Things to know about 100G switch

More than a decade ago, the demand for high bandwidth networks from enterprise core businesses and applications stimulated the demand for 100G networks. For example, in order to cope with more than 1 billion transactions and petabytes of data per day, the New York Stock Exchange decided to deploy a 100GE network in 2010. Demands for 100G network switches are mainly focused on data centers, and high-end enterprise and campus applications to solve the problem of large traffic data transmission.  

 

When it comes to 100G, we must first think of the high-speed network transmission capability. In terms of 100G switch products, what are the technical and functional characteristics of the 100G switch compared with the previous gigabit and 10-gigabit series switch equipment? First of all, because of the high-density 10G access demand, more and more traffic and services are converging, 100G network switches must have the characteristics of large capacity, high stability, and virtualization. In addition, the increase in port capacity puts forward higher requirements for the overall capacity and performance of the switch, which requires more advanced high-integration technology to achieve 100G.

 

At present, the port rate of mainstream data center switches is upgrading from 10G/40G to 25G/100G, and the market demand for 25G/100G data center switches is growing explosively. After decades of development, the 100G switch technology in the market is mature enough both in hardware and software. Next, we will introduce a QSFPTEK 10G/40G/100G stackable layer 3 switch with cost-effective and high performance.
