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.

    Using this 25G SFP28 LR on my Cisco WS-N9K-C93108TC-EX switch, no errors were reported, very easy to use, plug and play. Also purchased the matching LC optical fibre from the website, overall a very easy shopping experience and you can quickly find other products you need.

    I recently obtained multiple 25G SFP28 modules from QSFPTEK and found them to be comparable to Cisco's own transceiver modules, with the only noticeable difference being the more affordable price of the third-party transceivers. Delivery was prompt, and the modules were highly functional straight out of the packaging, working seamlessly with my Cisco C9500-24Y4C switches. I would definitely consider purchasing from QSFPTEK again for any future needs.

    I purchased a 25G optical module for my Cisco N9K-C93180YC switch. QSFPTEK AM confirmed the module's compatibility before I placed the order. Upon plugging the module into the switch's port, it was able to read the module's TX and RX power.

    We've been using the 25G SFP28 LR from QSFPTEK for a while now and I'm happy with the experience. No hassle and it's more affordable than the original Cisco brand. We will continue to use these products in the future and will continue to source at QSFPTEK.

    I got a C9200L-24PXG-2Y as an aggregation switch in my server room, I find it works well with the 25g lr over my os2 smf. Maybe review later again if there are any issues.
