    Full analysis of the latest 25G SFP28 series optical modules
    • December 07. 2022

    In recent years, with the rapid development of the Internet, cloud computing and big data, the increasingly high demand for bandwidth has promoted the construction of IT infrastructure data centers. The current speed standard of 10G Ethernet cannot meet the rapid growth of network traffic demands of large and medium-sized enterprises. From the perspective of resource investment and cost, 25G is th...

  • 40G QSFP+ SR4 VS 40G QSFP+ BIDI optical module
    40G QSFP+ SR4 VS 40G QSFP+ BIDI optical module
    • December 09. 2022

    Common 40G QSFP+ multi-mode optical modules include SR4 and BIDI, so what is the difference between the two multi-mode optical modules? And how to choose it? ETU-LINK will introduce these two optical modules to you. The package type of QSFP-40G-SR4 is QSFP+, the interface type is MPO, the transmission distance can reach up to 100 meters when used with OM3 patch cords; and the transmission distance...

    Data center cabling solution---DAC direct attach cable
    • December 13. 2022

    DAC cable is often used in short-distance cabling schemes in data centers. Compared with other AOC active optical cable and optical module transmission schemes, it has high performance cost ratio , but the short transmission distance is its limitation. If the equipment spacing exceeds the length of direct attach cable, it is necessary to choose AOC active optical cable and optical module scheme. T...

    The Development Status of 800G Optical Module
    • December 16. 2022

    With the application of cloud computing, VR/AR, AI, 5G and other technologies, the bandwidth capacity of the global Internet has become very large. The flat two-layer leaf-spine (Leaf-Spine) architecture used in ultra-large-scale data centers requires a large number of interconnections, because each Leaf is fully interconnected with the spine to maximize non-blocking network connections between sw...

  • Application of 10G DAC and 40G optical module in Spine-Leaf architecture
    Application of 10G DAC and 40G optical module in Spine-Leaf architecture
    • December 24. 2022

    The traditional computing network of data centers is composed of the access layer, the convergence layer and the core layer. However, with the rapid growth of new applications and the amount of data, the requirements on the network architecture are constantly raised. Therefore, a new network topology architecture -- leaf-spine structure is born in the data center. Now, ETU-LINK will introduce the ...

    100G era has come, demand for 100G optical modules has increased significantly
    • January 11. 2023

    Due to new applications such as 4K high-definition video, live broadcast and VR have promoted the rapid growth of global network traffic, and new applications such as cloud computing, laaS services and big data have higher requirements for data transmission in data centers, global data centers have been upgraded from the original 10G/40G to 25G/100G, which has triggered an increase in the demand f...

  • What direction will data center optical interconnection develop in the future?
    What direction will data center optical interconnection develop in the future?
    • March 14. 2023

    In this blog, ETU-LINK will explain the development direction of optical interconnection of data center in the future from three aspects: geographical location distribution, bandwidth demand and optical module of data center. The construction of data center needs to occupy a relatively large land area, and the current price of land remains high, especially in some more developed cities, so the int...
