## Summary description

A BlueOptics QSFP112 direct-attach copper cable (CBL-NTWK-0912-QSFP-1-BL) designed for 400GBASE-CR4 links. The 1 m passive DAC with QSFP112 connectors supports high-speed 400 Gbps data transmission for Infiniband and Ethernet applications, suitable for short-reach interconnects between switches, routers and servers in data centers.

## Long description

The BlueOptics QSFP112 Direct Attach Cable CBL-NTWK-0912-QSFP-1-BL is a 1 m passive copper DAC engineered for 400GBASE-CR4 short-reach links. Equipped with QSFP112 connectors on both ends, the cable supports 400 Gbps bi-directional data transfer and is designed for direct connections between switches, routers and servers in data centres. It is suitable for high-density top-of-rack and spine deployments where low-latency, high-throughput interconnects are required.
Advantages
This direct-attach copper cable offers a plug-and-play solution with no additional transceivers or optical modules required, reducing power consumption and component count. The QSFP112 form factor ensures compatibility with ports engineered for 400GBASE-CR4 and provides reliable signal integrity over short distances. Its 1 metre length is compact for tidy cable management in rack environments and helps to minimise insertion loss compared with longer passive assemblies.
Suitable for
Short-reach 400G interconnects between switches in data centre racks
Connections from top-of-rack switches to aggregation or spine switches
Direct links between servers and network devices that support QSFP112
High-density networking environments where passive DACs are preferred to optics
When it may not be suitable
This passive copper DAC is intended for short-reach connections and is not suitable for long-distance links or campus-wide backbone runs. It requires QSFP112-compatible ports and will not function in equipment that only supports optical transceivers or different connector types. Environments that require active cable features, signal conditioning, or extended reach should use alternative active DACs or optical modules.
Key specifications
Data rate: 400 Gbps (400GBASE-CR4)
Connector type: QSFP112 on both ends
Length: 1 metre
Media: passive copper direct attach cable
Applications: Ethernet and Infiniband short-reach interconnects
How to use
Install the cable by firmly inserting each QSFP112 connector into the corresponding 400G port until the latch engages. Verify link status through the host device management interface and ensure matching port configuration (speed and lane mapping) on both connected devices. Route the cable to avoid sharp bends and excessive strain; maintain the 1 m routing within rack units for optimal performance. No optical transceivers or additional power are required for passive operation.
What to consider before purchase
Confirm that both devices have QSFP112 ports supporting 400GBASE-CR4
Verify that a 1 m cable length meets your rack layout and cable management needs
Check equipment compatibility lists for passive DAC support and firmware requirements
Assess whether passive copper is acceptable for your temperature and EMI environment
Usage recommendations
Use this 1 m QSFP112 passive DAC for short, high-throughput connections inside racks and between adjacent network devices. Keep cable paths free of tight bends, avoid kinking, and secure the cable to prevent tension on the connectors. For longer distances or environments with stricter EMI or thermal requirements, consider active DACs or optical transceivers instead.
