    Connection solution between 12 core optical fiber distribution box and 40G 100G optical module
    • July 11. 2023

    In generic cabling, MTP / MPO components have strong flexibility, which can realize 72 core optical fiber cabling at most, and 12 core optical fiber distribution box is mainly used for 40G / 100G data center. In 40G data center, 12 core optical fiber distribution box can be used to connect 40G QSFP + SR4 optical module and 10G SFP+ SR optical module; In 100G data center, 12 core optical ...

  • 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...

    How to judge the performance of fiber optic patch cord connectors?
    • July 28. 2023

    As an important component of optical communication systems, the quality of fiber optic jumpers' connectors determines the transmission quality of the network. The function of the connector is to precisely connect the two separated fiber end faces, so that the optical energy output by the transmitting fiber can be coupled to the receiving fiber to the maximum extent. Optical fiber connectors i...
