    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...

  • QSFP-100G-ER4 Lite Optical module --- data center long-distance transmission solutions
    QSFP-100G-ER4 Lite Optical module --- data center long-distance transmission solutions
    • May 31. 2023

    In this blog, ETU-LINK will introduce the QSFP-100G-ER4 Lite optical module, which uses LWDM multiplexing technology and operates in the wavelength range of 1295, 1300, 1304, and 1309. The optical signal is multiplexed by a WDM wavelength division multiplexer and transmitted on a single-mode fiber through an industry-standard LC connector. At the receiving end, the SOA amplifies the signal before ...

    What kind of changes will the emergence of 400G bring to data centers
    • May 27. 2023

    Recently, 400G Ethernet has become a hot topic in the communication industry. It is both an outlet and a challenge. Network equipment manufacturers have launched 400G switches, and optical communication products have also launched 400G optical modules. In this article, ETU-LINK is about the impact of the emergence of 400G switches and 400G optical modules on data centers.   First of all,...

  • 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...

  • 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...

    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 ...

    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...
