    What is the difference between single fiber and dual fiber optical module?
    • December 01. 2022

    In this issue, ETU-LINK will introduce what is a single fiber optical module and a dual fiber optical module, and what are the differences between them. So what are single fiber optical modules and dual fiber optical modules? Single fiber optical module is an optical module product with only one optical fiber port. It can transmit and receive optical signals at the same time by inserting only one ...

    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
    • 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 ...
