InfiniBand/fibre optic cable BlueOptics 332-1362-BL 0.5 m QSFP Male/Male

The BlueOptics 332-1362-BL is a 0.5 m InfiniBand/fibre optic direct attach cable with QSFP Male to QSFP Male connectors. Designed for short-reach high-speed links, this cable supports up to 40 Gbit/s data transfer and is intended for rack-to-rack or intra-rack connections in data centers and high-performance computing environments. The cable implements a passive twinax construction compliant with MSA guidelines and is compatible with hardware that supports QSFP 40GBase-CR4 connections.

Advantages

This BlueOptics cable provides low-latency, high-bandwidth connectivity over a 0.5 m distance while consuming minimal power due to its passive design. It is manufactured using MSA-compliant components and tested for interoperability with major networking platforms, which helps ensure reliable signal transmission for Ethernet, FCoE, Fibre Channel and InfiniBand applications. The cable’s compact length and QSFP to QSFP connectorization simplify short-distance deployments inside racks or between adjacent racks.

Suitable for

• Short-reach rack-to-rack or intra-rack 40 Gbit/s connections
• High-performance computing and cluster interconnects
• Switch-to-switch, switch-to-storage, and server interconnects that support QSFP 40GBase-CR4
• Environments requiring low latency and low power passive direct-attach solutions

Key specifications

• Connector type: QSFP Male to QSFP Male
• Length: 0.5 meters (0.5 m)
• Data rate: up to 40 Gbit/s
• Transmission type: passive twinax copper (direct attach cable)
• Wire gauge: 30 AWG
• Standards: MSA-compliant QSFP 40GBase-CR4 transmission
• Supported protocols: Ethernet, FCoE, Fibre Channel, InfiniBand (up to 40G)

How to use

Connect each QSFP connector to the corresponding QSFP port on compatible switches, servers or storage devices. Ensure that the host hardware and firmware support passive QSFP 40GBase-CR4 direct attach cables. Route the cable inside the rack or between adjacent racks without sharp bends and avoid exceeding the manufacturer’s minimum bend radius. No external power or transceiver configuration is required for passive operation; however, verify link status and speed in the device management interface after installation.

Recommendations

Use this 0.5 m QSFP direct attach cable for short-distance links where low latency and cost-effective passive connectivity are priorities. Confirm device compatibility and, if possible, test a sample in your target hardware to validate full functionality before wide deployment.
