  • Several ways to Improve the Transmission Rate of Optical Modules
    Several ways to Improve the Transmission Rate of Optical Modules
    • September 22. 2022

    As data centers and telecom operators require higher transmission rates for optical modules, what technologies do optical module manufacturers use to achieve higher transmission rates? This article ETU-LINK will reveal the answer for you. 1. Increase the baud rate. The baud rate refers to the modulation rate of the data signal to the carrier. This method is mostly used for low rate optical modules...

    High-order PAM4 modulation 50G SFP56 SR optical module
    • October 24. 2022

    In this blog, ETU-LINK will talk about the 50G SFP56 SR optical module using PAM4 modulation technology. Since the PAM4 signal has four level values, the PAM4 signal can be used in the same physical bandwidth of the channel. Downlink transmission is twice the amount of information compared to NRZ signals, enabling single-channel 50G applications. Therefore, PAM4 signal modulation has become t...

    • October 25. 2022

    It is believed that everyone should be very familiar with the packaging of optical modules after reading the previous articles of ETU-LINK. So how much do you know about the packaging of optical components in optical modules? In this article, ETU-LINK will take you to understand the packaging process of optical devices.   At present, the common optical device packages include Box, COB, TO-CAN...

  • What is WDM technology?
    What is WDM technology?
    • October 29. 2022

    This blog ETU -LINK will take you to read what is WDM, before that we first to get to know why the WDM technology, it appears from the background of the Internet, development rapidly in a short few decades, so operators urgently needs a lot of network capacity to meet growing customer service requirements.   For network expansion, simply increase the transmission capacity linearly by increasi...

    What is the cabling structure under the leaf ridge network?
    • November 01. 2022

    As networks grow in size, we are seeing a shift from the traditional three-layer network architecture to a flatter, wider Spine-Leaf architecture. Most modern e-commerce, social media and cloud applications use distributed computing to serve their customers.  Distributed computing means that servers speak to servers and work in parallel to create dynamic web pages and answer customer question...

  • 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...
