  • How to interconnect the Gigabit RJ45 port with the SFP optical port -Copper-T module
    How to interconnect the Gigabit RJ45 port with the SFP optical port -Copper-T module
    • May 10. 2023

    Now Gigabit Ethernet has been popularized in a large area, and Gigabit Ethernet switches are also widely used in scenarios such as enterprise networks and optical access networks. Gigabit Ethernet has two types of ports, namely RJ45 and SFP ports. These two ports can support the highest transmission rate of Gigabit, and can also be backward compatible with the transmission rate of 10/100M.   ...

    What are the differences between single-mode and multi-mode fiber optic patch cords How to choose
    • May 16. 2023

    Before understanding the differences between single mode and multimode, we need to know that light propagates in a fiber as a set of independent beams, which propagate at a specific angle to the fiber axis and are called modes. We can distinguish between single mode and multimode by transmission mode. Single mode fiber supports one mode, while multimode fiber supports multiple modes. Below, ETU-LI...

    Introduction and application of 32G SFP28 FC single-mode optical module
    • May 19. 2023

    The previous storage technology only uses the storage device as an auxiliary device of the server. The large-capacity data exchange between servers can only rely on traditional networks, and cannot adapt to the development of IT technology in terms of speed, security, cross-platform sharing, and unlimited expansion. Under such circumstances, SAN technology came into being. fiber Channel SCSI ...

  • OM2, OM3, OM4 multimode fiber, which one is better
    OM2, OM3, OM4 multimode fiber, which one is better
    • May 23. 2023

    Multimode fiber has been developed from OM1 to OM5 now, so which one is better among OM2, OM3, and OM4 multimode fiber? In this blog, ETU-LINK will explain to you.   Multimode fiber is mainly used for optical transmission with a wavelength of 850nm. Here, the two points of effective mode bandwidth and full injection bandwidth can be compared separately. First, let us understand what bandwidth...

  • Compared with Media converter, what’s advantages of optical modules?
    Compared with Media converter, what’s advantages of optical modules?
    • May 26. 2023

    Media converter are Ethernet transmission conversion units that convert electrical signals and optical signals to each other, so they are also called photoelectric converters. The main purpose of using Media converter is to extend the transmission distance of the signal. Since the twisted pair wires used in our daily life, that is, network cables, have a very limited transmission distance, if...

    Single-mode 10G and 40G interconnect solution—40G QSFP+ PSM4 optical module
    • June 20. 2023

    We all know that the multi-mode 40G SR4 optical module adopts 4-way 10G parallel technology and MPO interface, and can use MPO-LC multi-mode OM3 fiber jumper and 10G SR for access。So are there any 40G optical modules that can be connected to single-mode 10G LR optical modules?In this article, ETU-LINK will introduce the next 40G optical module that can be interconnected with 10G LR optical module ...

  • 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...

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