    Is it possible that QSFP+ optical modules be used on the QSFP28 port?
    • July 28. 2017

    With the rapid development of optical communications in recent years, the user demand for the network has also soared. The rapid rise of 100G optical transceiver in the market has become the focus of attention of users. Users of 100G networks often meet some problems. For example, the maximum transmission distance of QSFP28 optical module is 10km. To achieve a longer distance data transmission, ne...

    How was 25G Ethernet technology born?
    • August 02. 2017

    Energy saving and cost are two important factors that need to be considered when deploying data centers. The price of 40G optical module and 100G optical module is too high and the power consumption is too large, and the speed of 10G optical module can not meet the demand of network. Therefore, 25G SFP28 optical module was born in this case, just to make up for the deficiency between the them, gre...

    Why are original modules so expensive?
    • August 14. 2017

    With the development of optical communication industry, the demand for optical module is increasing rapidly. As we all know, the price of the original optical module is very high, and many users can only flinch from it. Therefore, many third party optical modules have appeared on the market. Some third party optical modules have good compatibility, and their performance is comparable to that of or...

    Do you know about PON optical transceiver
    • August 23. 2017

    The PON optical transceiver is a high performance optical module for the PON system, also known as the PON module, conforms to the ITU-T G.984.2 standard and the MSA. It uses different wavelengths to send and receive signals between the OLT (optical line terminal) and the ONT (optical network terminal). Classification of PON optical modules: 1. According to the package type: SFF/SFP/SFP+ and XFP o...

    The influence of temperature to the optical transceiver
    • August 25. 2017

    As a sales of Optical Transceiver Modules should know that the working temperature will influence the parameters of the optical transceiver. When the applied environment temperature of the module is changed, then the working current will change as the temperature changes. At the same time, it will lead to changes in the parameters of the optical transceiver.Thus affecting the normal transmission o...

    Module verification is very important
    • August 28. 2017

    Optical transceiver is a small product, it seems simple. In fact, it is assembly completed after more than 10 processes, but still can’t be sold. Because the product need to be strictly testing before shipment, including parameter testing, aging testing, distance testing (fiber testing) and switch testing. We've had a detailed explanation of the tests except switching testing, today we're going to...
