  • 16G FC CWDM SFP+ series optical module introduction
    16G FC CWDM SFP+ series optical module introduction
    • May 06. 2021

    16G FC CWDM SFP+ series optical modules are mainly used in FC (Fibre Channel) networks. Fibre Channel technology (Fibre Channel) is a network storage switching technology that can provide long-distance and high-bandwidth. It can be used in storage, server and client nodes. Realize the transmission of large data files between. ETU-LINK will focus on introducing the 16G FC CWDM SFP+ series opti...

  • What is the influence of the transmitting power and receiving sensitivity on the optical module?
    What is the influence of the transmitting power and receiving sensitivity on the optical module?
    • May 08. 2021

    We need to pay attention to the two parameters of transmit optical power and receiving sensitivity when purchasing optical modules, because these two parameters are one of the key factors to ensure the normal communication of optical modules. Next, ETU-LINK will introduce to you what are the transmitted optical power and the receiving sensitivity? And how to test the optical power of the optical m...

  • The difference between multimode fiber OM3-150 and OM3-300
    The difference between multimode fiber OM3-150 and OM3-300
    • May 21. 2021

    The OM3 patch cord is a 10-Gigabit multi-mode patch cord. The multi-mode fiber uses light-emitting diodes as the light source, allowing multiple beams of light to propagate in the fiber at the same time, thereby forming a mode dispersion. Mode dispersion technology limits the bandwidth and distance of multimode fiber. Therefore, the core wire of multimode fiber is thick, the transmission speed is ...

  • The difference between switches and routers and optical module collocation solutions
    The difference between switches and routers and optical module collocation solutions
    • May 25. 2021

    We all know that a switch is a network device used to forward electrical (optical) signals, while a router is a hardware device that connects two or more networks. It acts as a gateway between networks and reads the data in each packet. The address then determines how to transmit the dedicated intelligent network device. Next, ETU-LINK will give you a detailed introduction to the differences ...

  • Introduction of 16G FC DWDM SFP+ series optical module
    Introduction of 16G FC DWDM SFP+ series optical module
    • June 08. 2021

    The Fibre Channel protocol was formulated by the X3T11 team of ANSI in 1988. It has the characteristics of high bandwidth, multi-media, and long-distance transmission. It can realize the transmission of large data files between storage, server and client nodes. In this article, ETU-LINK will focus on introducing the 16G FC DWDM SFP+ series optical modules for 16G Fibre Channel networks. ...

  • Introduction of 40G BiDi QSFP+ dual fiber bidirectional optical module
    Introduction of 40G BiDi QSFP+ dual fiber bidirectional optical module
    • June 15. 2021

    In 40G short-distance optical network transmission, the conventional optical module solution is to use QSFP-40G-SR4 optical module and 12-core MPO multi-mode OM3 fiber patch cord. Although this solution can realize the upgrade of 10G network to 40G network, it uses MPO branch jumpers to connect 10G equipment and 40G equipment are obviously too expensive, so the industry has given a new optica...

  • What are the types of Gigabit optical modules
    What are the types of Gigabit optical modules
    • June 17. 2021

    Gigabyte optical module has been a very mature series of products, the common transmission rate is 1.25G, 2.5G, etc., and the package type is SFP. There are many models of gigabit optical modules. Next ETU link will give you a detailed introduction to the types of gigabit optical module.   Gigabyte optical modules can be divided into two categories, namely, single fiber and dual fib...

  • Optical fiber test method
    Optical fiber test method
    • July 09. 2021

    Optical fiber testing is divided into primary testing and secondary testing. The primary testing is also the basic testing. It mainly tests the insertion loss (that is, attenuation) of the optical fiber and the length of the optical fiber link. No matter it is single-mode fiber or multi-mode fiber, they are all made of glass fiber, and natural loss will inevitably occur when optical pulse sig...
