Know before you buy
This cable is designed for high-speed, short-distance connections within data centers, such as linking servers to top-of-rack switches. It is ideal for low-latency environments where devices are in close proximity.
No, this is a passive direct attach cable. It is hot-pluggable, meaning you can simply plug it into your SFP28 ports and it will be recognized by your networking equipment without needing manual setup.
Yes, this cable is TAA compliant, which meets the requirements for procurement by the U.S. government and other regulated entities.
While the SFP28 connector is physically similar to SFP+, it is specifically engineered for 25 Gbps data rates. You should verify that your specific switch or server port supports the 25G standard before installation.
A passive cable does not contain active electronic components to boost the signal. This design keeps power consumption and latency to a minimum, making it a cost-effective and efficient choice for short-run connections.
