## Summary description

BlueOptics BlueLAN passive QSFP112 Direct Attach Cable (1 m) supports 400GBASE Ethernet and InfiniBand connectivity. This fixed twinax DAC provides a direct electrical connection between QSFP112 ports for short-reach high-speed links, suitable for data center spine-leaf connections, switch-to-router links, and server interconnects where low latency and low power are required.

## Long description

The BlueOptics BlueLAN passive QSFP112 Direct Attach Cable 400GBASE Ethernet / InfiniBand, 1 m is a fixed twinax DAC designed for short-reach, high-speed interconnects. It provides a direct electrical connection between QSFP112 ports and supports 400GBASE Ethernet and InfiniBand protocols. The cable is intended for use in data centre topologies requiring low latency and low power consumption, such as spine-leaf links, switch-to-router connections and server-to-switch interconnects.
Advantages
This passive QSFP112 direct attach cable delivers a straightforward, low-latency electrical link without the need for active components or transceivers. It offers predictable signal integrity for short distances and reduces power consumption compared with active optical solutions. The fixed 1 m length simplifies cable management in dense rack environments and is compatible with equipment that accepts QSFP112 form-factor interconnects.
Suitable for
Data centre spine-leaf and leaf-to-leaf links requiring 400G bandwidth
High-throughput switch-to-switch and switch-to-router connections
Server to top-of-rack switch interconnects with minimal latency requirements
InfiniBand fabrics and high-performance computing clusters using QSFP112 ports
When it may not be suitable
This passive twinax DAC is intended for short-reach links; it is not suitable for long-distance connections or runs that exceed the supported electrical reach for passive QSFP112 cables. Environments that require optical isolation, longer link spans, or active signal conditioning will need optical transceivers or active cables rather than a passive DAC.
Key specifications
Form factor: QSFP112 direct attach cable (fixed twinax)
Supported protocols: 400GBASE Ethernet and InfiniBand
Length: 1 m
Link type: passive electrical connection
Designed for: short-reach high-speed interconnects with low latency and low power
How to use
Insert each QSFP112 connector into the corresponding QSFP112 port on your network devices until the latch engages. Ensure connectors and ports are free of dust and debris before insertion. Verify link status and speed through device management interfaces after connection. For reliable operation, avoid sharp bends and excessive mechanical stress on the cable and maintain appropriate airflow around connected equipment.
What to consider before purchase
Verify both devices support QSFP112 ports and the desired 400GBASE Ethernet or InfiniBand rates
Confirm 1 m length is sufficient for your rack or cabinet layout and cable management
Check device compatibility lists or vendor documentation for passive DAC support
Assess whether a passive electrical cable meets reach and isolation requirements for your deployment
Usage recommendations
Use this 1 m passive QSFP112 DAC for short, high-density links inside racks or between adjacent racks where low latency and low power are priorities. For runs beyond typical short-reach limits or where optical links are required, choose appropriate optical transceivers or active cables.
