SFP and QSFP Cables (DACs)

DACs, the High-Speed Connections between Networks

When it comes to connecting networking equipment in high-density, high-bandwidth applications, SFP cables and QSFP cables – also called Direct Attach Cables (DACs) – that operate over passive copper are the most cost-effective interconnects available.

Limited in length due to their copper construction, they are perfect for intra-rack connections of switches, routers, servers, and other high-performance networking equipment.

In comparison to Active Optical Cables (AOCs) and modular mini GBIC SFP or QSFP transceiver solutions, you cannot beat the value of a high-performance, low-cost copper solution that consumes practically zero power.

DAC Benefits

Premium Connectivity
SFP and QSFP cables provide error-free ultra-high-bandwidth performance for data, storage, high-performance computing (HPC), and more.

Highly Affordable
The lowest-cost SFP and QSFP high-speed network connectivity solutions available. You won’t find a better value than DACs.

Convenient, All-in-One Cable Design
No more time consuming, expensive cleaning of fiber optic connectors to ensure optimal performance, just plug and play.

Reliable Performance
Once connected, the data keeps flowing. Additionally, a fully shielded design protects against EMI/RFI, so you never have to worry about signal disrupting interference.

Low Latency
DACs feature an all-in-one copper cable design with no opto-electronic conversion in its path and have none of the additional points of connection of a modular solution to ensure all signals arrive at the same time.
