In this article, ETU-LINK will introduce the 100G QSFP28 and 25G SFP28 cost-effective port branch connection solutions. The following will analyze and compare from the two aspects of saving space and cost. First of all, let's talk about why the cost performance is high, we can judge by comparing the cost. We can assume a scenario with an 8-slot chassis, which is fully equipped with 36 QSFP28 ports...

The current branch deployment of ports has become one of the popular ways to build networks, and has driven the development of the parallel optical module market. At present, the commonly used parallel modules are 40G QSFP+ SR4 and 100G QSFP28 SR4, which can be converted into four 10G/25G links for link. This parallel optical module is conducive to multi-link applications, such as the constru...
