Questions & Answers

more+
  • Have undergone any test programs? If yes, what are they?
    This module usually has the following tests: Normal/High Temperature Testing, Power Testing, Eye Diagram Testing, Sensitivity Testing, DDM Monitoring and Ping Package Testing.
  • Is it compatible with my Cisco C9500 series switch?
    You need to check whether the device is equipped with sfp28 ports or not by youself. Or tell us the specific switch model name (like C9500-48Y-4C) and then we'll check it for you. If the swich has bulit-in sfp28 ports, there will be no issue.
  • Can this 25G transceiver run at 10G? On your product page, I see it is connected with OM3/OM4 cables, but I only have OM2 cables, can I use OM2 directly?
    I'm sorry. It can only work at 25Gbps. However, you can use the OM2 cables to connect this 25G transceiver, but pls know the transmission distance would be less than 100m over OM2 cables.

    Wendy answered many of my questions and was always very responsive whenever I emailed her. I asked about the specs of the product and she sent me a complete spec report that was identical to what was shown on the website.

    I bought three compatible modules from Cisco, Juniper and Arista. The delivery speed was very fast and the account manager also gave me feedback on the logistics information in time. It is plug-and-play, compatible and stable, and the transmission is also very stable, and it can achieve the expected transmission rate, which is great.

    The express was very fast and it was delivered to my address in three days. The product was well packaged so I didn't have to worry about it being damaged during transportation. It was plug and play, no additional configuration required, and overall it was a good shopping experience.

    We required SFP-25G-LR modules for our data center setup. Our switch brand is Cisco, and the original product was considerably pricey. However, these 25G transceivers not only successfully passed our rigorous performance tests but also seamlessly integrated with our switches. This product has certainly exceeded our expectations, earning a resounding thumbs up from our team.

    The 25G SR modules I purchased were an excellent choice for my network. They provide reliable and high-speed connectivity, and I love the fact that I can upgrade to 100G in the future without removing them.
