## Summary description

The BlueOptics 720196-B21-BL is a 1 m InfiniBand/fibre optic cable featuring QSFP connectors on both ends. It is designed for high-speed data transmission and reliable connectivity in data centers and networking environments.

## Long description

The BlueOptics 720196-B21-BL is a 1 m InfiniBand/fibre optic cable with QSFP connectors on both ends. It is intended for short-range, high-speed links in data centres and rack environments, supporting 40GBase-CR4 / 40 Gbit/s signalling where hardware supports QSFP-to-QSFP direct-attach connections. The cable is offered as a passive direct attach solution designed to deliver reliable electrical signal transfer over a one metre distance and to be compatible with major networking platforms that accept QSFP passive twinax copper direct attach cables.
Advantages
The cable provides a compact, low-latency physical link for high-bandwidth interconnects between switches, routers, servers and storage systems. As a passive twinax direct attach solution it requires no additional power or active electronics in the cable itself, which simplifies installation and reduces power consumption. The construction follows MSA-compliant QSFP direct attach guidelines and uses high-quality components to achieve consistent interoperability and a long service life when deployed in supported equipment.
Suitable for
Short-distance 40 Gbit/s links between rack-mount switches and adjacent racks
High-throughput connections between servers and storage systems with QSFP ports
InfiniBand and Ethernet setups that accept passive QSFP-to-QSFP twinax direct attach cables
Data centre top-of-rack and aggregation layer interconnects
Key specifications
Connector type: QSFP male to QSFP male
Cable length: 1 metre
Rated data rate: up to 40 Gbit/s (40GBase-CR4 compatible)
Cable type: passive twinax/direct attach copper
Wire gauge: 30 AWG (as typical for this cable type)
How to use
Ensure both devices have compatible QSFP ports that support passive 40GBase-CR4 direct attach cables. With equipment powered down or in maintenance mode if recommended by the manufacturer, insert each QSFP connector into the matching port until it latches. Verify link status through the switch or server management interface and confirm negotiated link speed of 40 Gbit/s where supported. To avoid damage, route the cable to minimise sharp bends and mechanical strain and avoid exposure to liquids or high heat sources.
Usage recommendations
Use this 1 m passive QSFP-to-QSFP cable for short interconnects inside racks or between adjacent racks. Confirm device compatibility with passive twinax DACs and the required 40GBase-CR4 signalling before deployment. For longer distances or optical-transceiver based links, choose an appropriate fibre optic transceiver and patch cable instead.
