  • Does 400GBASE-SR8 support DSP?
    Yes, The 400GBASE-SR8 incorporates DSP (Digital Signal Processing) technology, offering greater flexibility than CDR. DSP allows for tailored configuration adjustments to accommodate diverse application requirements.
  • I want to build a 850m optical link, can I use The 400GBASE-FR4?
    Yes, The 400GBASE-FR4 optical module's maximum transmission distance is 2 km, so it can be used for an 850m connection.
  • What type of optical cable should be used with 400G-SR8?
    The 400G-SR8 optical module employs a single-row, angled (APC) MTP16 connector to establish a connection with parallel multi-mode fiber, facilitating the linkage of 8 fiber pairs. We recommend utilizing the QSFPTEK MTP-16 APC OM4 Cable for optimal performance.

    This is my second time buying from QSFPTEK, and I gotta say, they've been solid. Last year, I grabbed some 100G QSFP28 SR4 and 10G modules for a project, and they've been chugging along without a hitch. So, when my company needed some 400G modules for our spine-leaf connections, QSFPTEK was the first place I thought of. And man, was I relieved to see they had them in stock. Talia threw in a recommendation for an MTP-16 OM4 cable to hook up the transceiver to my switch, so I figured why not? Three days later, the goods were at my door. Couldn't be happier with the whole deal.

    A few years ago, we collaborated with QSFPTEK to deploy our 10G network, primarily because their products were cost-effective. I never thought that I could depend on QSFPTEK for our high-speed transmission needs as well. To my surprise, QSFPTEK continued to make progress, and their 400G modules and MTP cables worked seamlessly with our Cisco switches, resulting in a smooth 400G direct connection.

    Our goal was to upgrade our network system to achieve higher speeds, so we opted for a 400G upgrade and needed to select appropriate transceivers. Since we didn't require long-distance transmission, the 400GBASE-SR8 transceivers were the perfect fit for us. Initially, we were apprehensive that these modules might not be compatible with our Cisco switches, but to our delight, they exhibited outstanding connectivity, and all performance metrics were within normal parameters. I highly recommend them!
