    What factors need to be considered when purchasing optical modules?
    • May 05. 2023

    With the rapid development of the communication industry and data centers at home and abroad, the demand for optical modules has increased sharply. In addition to the original optical modules of equipment manufacturers, there are also third-party optical module manufacturers. So how should we choose optical modules? In this article, ETU-LINK will introduce to you what factors we need to consider w...

    According to the customer's feedback, how should we analyze and solve the issue that the switch and optical module are incompatible or cannot be used? In this article, ETU-LINK proposes the following solutions to this issue.   Optical fiber patch cord collocation problem If the optical module does not respond to being inserted into the network cord of the switch, check whether the optical fib...

  • Why does the new data center not use OM2 multi-mode fiber?
    Why does the new data center not use OM2 multi-mode fiber?
    • May 12. 2023

    Why don’t data centers use multi-mode OM2 fiber anymore? In this article, ETU-Link will reveal the answer for you. Firstly, OM2 is mainly a traditional 50/125 micron graded index multi-mode fiber. OM2 fiber is based on LED light source in terms of standard and design, and has low bandwidth requirements. It cooperates with LED to transmit 1000Mbit/s and lower rates. OM2 will withdraw from the data ...

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

    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 ...

    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 ...
