    Application of 10 Gigabit Optical Module in Building Network Construction
    • September 28. 2021

    With the gradual improvement of living standards, the concept of networked and intelligent buildings is no longer unfamiliar to everyone. In intelligent buildings, we can not only exchange data information quickly, control lights and adjust air conditioning through the network system, but also build intelligent scenes such as network monitoring systems and intelligent parking systems. In order to ...

  • Application of 10G SFP+ DWDM Wavelength Division Optical Module in Long-distance Backbone Network
    Application of 10G SFP+ DWDM Wavelength Division Optical Module in Long-distance Backbone Network
    • September 25. 2021

    DWDM is a dense wavelength division technology. This technology multiplexes the tight spectral spacing of a single optical fiber carrier in a designated optical fiber in order to utilize the achievable transmission performance. This technical solution is used to increase the bandwidth of the existing laser technology on the optical fiber backbone network. The following ETU-LINK will introduce 10G ...

  • Application of 10G SFP+ CWDM Wavelength Division Optical Module in Metropolitan Area Network
    Application of 10G SFP+ CWDM Wavelength Division Optical Module in Metropolitan Area Network
    • September 23. 2021

    Nowadays, the rapid development of data services has led to an increasing speed of IP network convergence, so network expansion is very important. In the construction of metropolitan area networks, there is a widespread problem of optical fiber shortage. Because metro expansion requires less channel numbers than trunk systems, and the distance is relatively short, optical amplification is not requ...

  • Precautions for the use of 10G SFP+ BIDI single fiber optical module
    Precautions for the use of 10G SFP+ BIDI single fiber optical module
    • September 16. 2021

    Optical modules can be classified into single-fiber and dual-fiber according to the number of interfaces. Dual-fiber optical modules have two optical fiber interfaces, and single-fiber optical modules have only one optical fiber interface. In addition to the difference in optical fiber interfaces, the use of the two is also different. Therefore, ETU-LINK will introduce the precautions for the use ...

  • The difference between AOC and DAC
    The difference between AOC and DAC
    • September 14. 2021

    In this article, ETU-LINK will introduce to you, what is the difference between active optical cable(AOC) and direct attach cable(DAC)? First, the AOC is composed of integrated optoelectronic devices. The signal transmission process is that the A terminal module converts the electrical signal into an optical signal, the optical signal is transmitted to the B terminal module by an optical fiber pat...

  • Introduction and application of 32G SFP28 FC single-mode optical module
    Introduction and application of 32G SFP28 FC single-mode optical module
    • September 11. 2021

    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. Fibre Channel SCSI techn...

    How many kinds of 10G network cabling solutions are there?
    • September 03. 2021

    In the establishment of a 10G network, we will face a choice, that is, whether we choose optical fiber cabling or copper cabling. Optical fiber cabling systems are divided into multi-mode(MM) optical fiber cabling systems and single-mode(SM) optical fiber cabling systems, among which 10G MM optical fiber cabling systems need to use 10G SFP+ MM optical modules, 10G AOC active optical...
