    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...

    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.   ...

  • 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 ...

    The Alcatel-Lucent OmniSwitch 6860 Virtual Chassis Full Layer 3 Ethernet Switch is a compact, high-density Gigabit Ethernet (GigE) and 10 Gigabit Ethernet platform designed for converged networks. There are four models of this series: OS6860-P24, OS6860E-48, OS6860E-P24Z8, and OS6860E-U28. The following ETU-LINK will introduce the OS6860E-48 switch and optical module solutions separately. &nb...

  • 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 ...

  • 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...
