Know before you buy
This cable is designed to bridge 40Gbps QSFP+ ports on switches or routers to four individual 10Gbps SFP+ ports on servers or storage devices. It is an ideal solution for high-density data center environments requiring cost-effective, short-reach connectivity.
Yes, this OptoSpan cable is specifically engineered and tested to ensure 100% compatibility with Cisco hardware standards. It functions as a reliable, plug-and-play alternative for your existing network infrastructure.
No, this is a passive copper cable, meaning it does not require external power to operate. It is pre-terminated for immediate plug-and-play use, drawing negligible power through the host port.
This specific model is 1 meter in length. Because it uses passive copper technology, it is optimized for short-reach, point-to-point connections within a single rack or between adjacent server cabinets.
The cable utilizes a 4-channel full-duplex design, allowing for simultaneous data transmission and reception across all channels. This architecture supports an aggregate throughput of up to 40 Gb/s with low latency.
