  • What are the differences between 100G QSFP28 CLR4 and CWDM4 optical modules?
    What are the differences between 100G QSFP28 CLR4 and CWDM4 optical modules?
    • August 16. 2022

    With the continuous surge in data center traffic, the market demand for 100G optical modules is also further increasing. Common 100G optical modules include SR4, LR4, ER4, etc. However, in practical applications, due to the length of the optical fiber link. Several types of optical modules alone cannot meet the most cost-effective optical network transmission solutions in data centers. Therefore, ...

  • Analyze the 100G QSFP28 SR4 branch solution from the perspective of cost and networking flexibility
    Analyze the 100G QSFP28 SR4 branch solution from the perspective of cost and networking flexibility
    • July 21. 2023

    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...
