  • What are the paths and cabling methods for 100G network upgrading
    What are the paths and cabling methods for 100G network upgrading
    • June 25. 2023

    With the continuous surge of traffic, major operators and data centers began to upgrade the network architecture economically, smoothly and reliably. At present, there are two 100G migration paths, namely 10G to 40G to 100G and 25G to 100G. Next, ETU-LINK will introduce the wiring schemes of these two paths.   1. 10G wiring The 10 Gigabit Ethernet technology defi...
