ALLNET 100G QSFP28 Direct Attach Cable 0.5m ALL4787-0,5

High-density data centers and high-performance computing clusters demand reliable, low-latency connectivity between switches, servers, and storage. The ALLNET ALL4787-0,5 is a 0.5-meter QSFP28 to QSFP28 Direct Attach Cable (DAC) that delivers 100 Gigabit Ethernet over passive copper twinax, eliminating the need for separate optical transceivers and reducing both cost and power consumption.

Who is it for

Network architects and data center operators who need short-reach, high-bandwidth interconnects within racks or between adjacent racks. Ideal for spine-leaf architectures, top-of-rack switching, and high-frequency trading platforms where every watt and microsecond counts.
