## Summary description

The BlueOptics CBL-NTWK-0446-01-BL is a 3 m InfiniBand/fibre optic cable with QSFP connectors. It features male/male connectors for reliable connectivity in high-speed data environments. Ideal for data centers and networking applications, this cable ensures efficient data transfer and minimal signal loss.

## Long description

The BlueOptics CBL-NTWK-0446-01-BL is a 3 m InfiniBand / fibre optic direct attach solution with QSFP male-to-male connectors designed for short-reach, high-speed links. It supports 40GBase-CR4 electrical signalling over a twinax copper construction compliant with MSA QSFP standards and is intended for rack-to-rack or intra-rack connections in data centres and networking environments where low latency and reliable throughput are required.
Advantages
This 3 m cable provides a passive direct-attach twinax connection that minimizes power consumption and latency compared with active optical transceivers. The QSFP male-to-male termination offers a compact form factor for high-density switch, router and storage interconnects. Manufactured to industry MSA guidelines and built from quality components, the cable is suitable for environments that require consistent 40 Gbit/s performance on short distances while reducing installation complexity and operational cost.
Suitable for
Short-reach 40 Gbit/s links between switches and routers
Interconnects between storage systems and host adapters
Intra-rack and adjacent-rack connections in data centres
InfiniBand, Ethernet, FCoE and Fibre Channel applications up to 40 Gbit/s
Key specifications
Length: 3 meters
Connector type: QSFP male to QSFP male
Data rate support: up to 40 Gbit/s
Cable type: passive twinax copper (Direct Attach Cable)
Wire gauge: 30 AWG
Form factor: QSFP (Quad Small Form-factor Pluggable)
Application: short-distance server, switch and storage interconnects
How to use
Insert each QSFP connector into the corresponding QSFP port on compatible network devices, ensuring firm seating and correct orientation. Use this passive DAC for connections within the same rack or between adjacent racks where the device datasheets specify support for passive 40GBase-CR4 or QSFP direct-attach cables. Verify that both endpoints support the required protocols (Ethernet, InfiniBand, Fibre Channel or FCoE) at 40 Gbit/s. Avoid excessive bending and secure the cable to prevent strain at the connector ends.
Usage recommendations
Handle the cable by the connector housings, maintain the minimum bend radius recommended for 30 AWG twinax, and confirm host and switch compatibility with passive QSFP DACs before deployment to ensure reliable 40 Gbit/s operation in data centre installations.
