## Summary description

Passive QSFP112 Direct Attach Cable by BlueOptics (BlueLAN) for 400GBASE Ethernet and InfiniBand connections. This 2 meter copper DAC provides a fixed high-speed link for switches, routers and network interface cards supporting 400GBASE ports. Designed for short-reach interconnects in data centers and high-performance computing environments where a direct attach solution simplifies cabling and reduces optical module requirements.

## Long description

BlueOptics BlueLAN passive QSFP112 Direct Attach Cable 400GBASE Ethernet / InfiniBand, 2 m is a factory-terminated copper DAC designed to provide a fixed, high-bandwidth connection between 400GBASE-capable network devices. The 2 meter length is intended for short-reach interconnects in data centers and high-performance computing racks where direct attach cabling simplifies infrastructure and avoids the need for active optical transceivers. This cable supports QSFP112 form-factor ports and is suitable for use with switches, routers and network interface cards that accept passive 400G direct attach links.
Advantages
The passive QSFP112 DAC offers predictable latency and stable electrical performance without consuming power for active components, which can lower device power draw. A factory-terminated copper assembly reduces deployment time and potential connector mismatch. The 2 m length balances reach and signal integrity for short interconnects while maintaining the full 400G data rate for Ethernet and InfiniBand applications.
Suitable for
 Short-reach interconnects within server racks and between adjacent racks
 400GBASE Ethernet uplinks and spine/leaf connections in data centers
 High-performance computing clusters using InfiniBand or Ethernet at 400 Gbit/s
 Direct-attach connections between switches, routers and NICs with QSFP112 ports
When it may not be suitable
This passive copper direct attach cable is not suitable for longer-distance links that require optical transceivers or active cabling solutions; its performance is limited to short-reach topologies. It may also be incompatible with devices that do not support QSFP112 passive DACs or that require vendor-specific transceiver authentication.
Key specifications
 Connector type: QSFP112 to QSFP112 passive copper assemblies
 Supported data rate: 400 Gbit/s
 Media: Twinax copper, passive
 Length: 2 meters
 Applications: 400GBASE Ethernet, InfiniBand
 Typical use: Short-reach rack and adjacent-rack connections
How to use
Insert each QSFP112 connector into the corresponding port on the two devices until the retention latch engages; ensure both ports are rated for 400G passive DACs. No additional configuration is required on the cable itself, but verify device firmware and port settings to enable 400G operation. Route the cable to avoid sharp bends and maintain recommended bend radius for twinax copper assemblies. For best results, install with devices powered down or after confirming the host ports support hot-plugging according to the equipment vendor guidance.
What to consider before purchase
 Confirm both endpoints have QSFP112 ports that accept passive 400G direct attach cables
 Verify the 2 m length matches rack layout and does not require longer reach
 Check device compatibility notes for any vendor locking or transceiver validation
 Ensure your environment and airflow requirements are compatible with copper DAC routing
Usage recommendations
Use the BlueOptics 2 m passive QSFP112 DAC for short, direct connections where consistent 400G performance and low power consumption are priorities. Maintain manufacturer-recommended bend radius, avoid repeated unplugging that may stress contacts, and verify device firmware and port settings to ensure full 400G operation.
