100g DAC

Note: Passive cables recommended for lengths up to 3m; active cables with signal conditioning for lengths up to 5m. Custom EEPROM programming and cable colors available.

1. 100G QSFP28 DAC – No Optics, No Hassle
Skip the optical transceivers and fiber cleaning. This direct attach copper cable delivers 100GBPS (4 × 25.78 GBPS) over twinax - just plug it into QSFP28 ports and you have a live link. Zero configuration, zero maintenance.

2. Passive up to 3m, Active up to 5m – Pick Your Range
Passive twinax (30–26 AWG with dual shielding) handles runs up to 3 meters and consumes less than 0.5W per end. Need 5 meters? The active version boosts the signal while staying under 1.5W per end. Same copper simplicity, extended reach.

3. Controlled 100Ω Differential Impedance, Low Insertion Loss
Engineered for 100Ω differential impedance across the full length, with insertion loss below 15 dB at 12.89 GHz on the passive version. That means clean eye diagrams and reliable 25.78 GBPS per lane performance.

4. Plug-and-Play Hardware with Programmable EEPROM
Zinc alloy housings with nickel plating stand up to repeated plugging. EEPROM is pre-programmable with vendor ID and serial number for seamless system recognition. ROHS compliant - ready for global deployment.

Short-Range 100G Copper Connectivity for High-Density Networks

• Top-of-Rack (ToR) Switching: Connecting 100G servers to top-of-rack switches within the same rack, providing cost-effective, low-latency 100G connectivity for data center applications where fiber is overkill.
• Switch-to-Switch Stacking: Used for stacking 100G switches in enterprise networks, providing reliable, low-cost links between adjacent switches in server rooms and wiring closets.
• Leaf-Spine Architecture: Deployed in data center leaf-spine network topologies for interconnecting switches within the same rack or adjacent racks where distance is short and low latency is critical.
• High-Performance Computing (HPC): Used in compute clusters for interconnecting nodes where low latency and high bandwidth are essential for AI/ML training and parallel processing workloads.
• Storage Area Networks (SAN): Deployed in 100G Ethernet storage environments for connecting servers to storage arrays and fabric switches within short distances.
• Cloud & Hyperscale Data Centers: Large-scale deployments where cost-effective, low-power 100G connections are needed for short-reach applications in high-density rack configurations.
• Test & Measurement Equipment: Used in network testers, protocol analyzers, and lab equipment for validating 100G network performance with repeatable, reliable connections.
• AI/ML Clusters: Connecting GPU servers and accelerators in AI training clusters where low latency and high bandwidth are critical for distributed training workloads.

1.Tom, network installer in Chicago
"Data center build used these for leaf-spine connections. The LSZH jacket version for plenum spaces passed fire code. The 3m active cables reach between racks. Good value compared to fiber."

2.Alex, AI infrastructure engineer in Oregon
"GPU cluster needed 100G connections between compute nodes. These DACS work perfectly with our NVIDIA switches. Zero errors in production. The 1.5m length is perfect for our rack layout."

3.Lisa, telecom engineer in Canada
"Edge data center needed 100G connections. The industrial temperature version handled our outdoor cabinets. The 2m cables worked perfectly. Good performance."

4.Raj, IT manager in India
"Data center migration used these DACS with Cisco switches. Plug and play, no configuration issues. The 2m length was just right for our rack layout. Good value."

5.Yuki, lab tech in Tokyo
"Test lab needed 100G connections for validation. These cables hold up to frequent plugging. The metal housings are durable. Good signal integrity on the scope at 100G."
