Description
The 40G QSFP+ to QSFP+ Active Direct Attach Copper (DAC) Cable, 24AWG, 15 meters, is engineered for high-performance, short- to medium-range connectivity in modern data centers. Unlike passive DAC cables, active DAC cables feature integrated circuitry that amplifies signals, reduces electromagnetic interference (EMI), and extends reliable link distance, ensuring optimal performance in demanding environments.
This 15-meter active DAC cable is ideal for connecting QSFP+ ports across switches, routers, host bus adapters (HBA), and storage devices. It supports 40-Gigabit Ethernet, QDR InfiniBand, Fibre Channel, and SONET applications, providing consistent high-speed data throughput for large-scale network infrastructures.
Built by FiberMania, the cable is manufactured to strict quality standards to deliver superior signal integrity, long-term durability, and dependable operation in data center and enterprise networks.

Q&A
Q1: What is the advantage of an active DAC over a passive DAC?
A1: Active DAC cables amplify the signal, reduce EMI, and extend reliable link distances beyond what passive DAC cables can achieve.
Q2: Can this cable be used for 40G Ethernet and InfiniBand QDR?
A2: Yes, it supports both 40GBASE-CR4 Ethernet and QDR InfiniBand applications.
Q3: Is 15 meters the maximum length available?
A3: FiberMania can provide custom lengths through OEM/ODM services.
Q4: Does it require external power?
A4: No, the active circuitry is self-powered via the QSFP+ ports.
Q5: How is signal integrity ensured over longer distances?
A5: The built-in active circuitry boosts signals, compensates for losses, and minimizes EMI for stable performance.
