Azlan NVIDIA DGX Spark DAC Cable, QSFP 112G Passive 32 AWG, 0.5m
Azlan NVIDIA DGX Spark DAC Cable, QSFP 112G Passive 32 AWG, 0.5m
NVIDIA DGX Spark Stacking DAC QSFP112 400G Cable 0.5m
A passive DAC cable designed for interconnecting (stacking) two or three NVIDIA DGX Spark systems via the native 400G QSFP port (ConnectX-7). The QSFP112 standard cable combines four channels, each with a transfer speed of up to 100Gb/s (PAM4-112G), for an aggregated throughput of 400Gb/s; however, the DGX Spark firmware limits the operating speed to 200Gb/s, and the use of slower QSFP56 (200G) cables is not compatible – the ConnectX-7 firmware will reject them as non-compliant. The Amphenol Spectra-Strip SKEWCLEAR EXD technology with 32 AWG conductors ensures a smooth high-frequency response above 20GHz, lower crosstalk, and greater flexibility compared to standard 30 AWG alternatives.
Key Features of the Azlan NVIDIA DGX Spark DAC Cable, QSFP 112G Passive 32 AWG, 0.5m
- Certified cable for NVIDIA DGX Spark stacking
- Fully compatible with ConnectX-7 (QSFP112) ports, functionally equivalent to Amphenol OEM cables NJAAKK-0006, NJAAKKR-0006, and NJAAKK-N911; the DGX Spark firmware recognises it as compliant and operates it at 200Gb/s
- Aggregated throughput of 400Gb/s (4×100Gb/s PAM4-112G)
- Four QSFP112 channels with PAM4 modulation provide full 400GbE capacity according to 802.3by/802.3bs standards
- The cable also supports 200GbE and HDR InfiniBand for deployment in various environments
- SKEWCLEAR EXD 32 AWG technology.
- Exclusive Amphenol Spectra-Strip 8-pair cable technology with extended reach
- Passive Direct Attach Copper (DAC) with no active components
- Passive design reduces power consumption and cost per port compared to optical solutions
- Die-cast zinc connectors with a 38-position design
- Backwards compatible with QSFP+ / QSFP28 / QSFP56
- The cable meets the QSFP112 MSA (Multi-Source Agreement) specification and is physically and electrically compatible with older generations of QSFP ports
- 0.5m length, RoHS 2 certified
The Right Cable for Interconnecting NVIDIA DGX Spark Systems
The ConnectX-7 firmware in NVIDIA DGX Spark systems requires cables certified exclusively for QSFP112 for stacking – slower QSFP56 (200G) alternatives are actively rejected as non-compliant, even though they would theoretically cover the 200Gb/s operating speed at which the DGX Spark operates. The Amphenol SF-NJAAKK0006-000.5M passive DAC cable meets this condition and is functionally equivalent to the OEM cables NJAAKK-0006 and NJAAKK-N911, which NVIDIA lists as reference interconnect cables for configuring two or three DGX Spark units. The 0.5m length covers the standard distance between units on the same desk or in the same rack, and the SKEWCLEAR EXD technology ensures signal integrity even under full 400G electrical load – with lower power consumption and without the costs associated with optical transceivers.
