  • If the optical module port is exposed to the external environment for a long time and is polluted, How to clean?
    If the optical module port is exposed to the external environment for a long time and is polluted, How to clean?
    • November 08. 2022

    Usually, the ports of the newly purchased optical modules are clean, and there is no need to clean the ports, but for the optical modules that are idle or have not been inserted into the dust cap in time, when they are used again, in order to prevent the transmission performance from being affected, we still have It is necessary to clean the port of the optical module first. Then the following ETU...

  • Why does the new data center not use OM2 multi-mode fiber?
    Why does the new data center not use OM2 multi-mode fiber?
    • October 27. 2022

    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 th...
