BlueOptics 332-1363-BL InfiniBand/glasvezelkabel 3 m QSFP zwart

The BlueOptics 332-1363-BL is a 3 m InfiniBand/fibre optic cable with QSFP connectors on both ends, designed for high-speed short-reach interconnects. The cable implements a QSFP-to-QSFP connection in a male/male configuration and supports data center and networking environments where up to 40 Gbit/s links over short distances are required. The product is presented as a passive 40GBase-CR4 direct attach solution suitable for rack-to-rack or intra-rack connections, complying with common MSA (Multi-Source Agreement) mechanical and electrical specifications for QSFP twinax solutions.

Advantages

The cable offers a compact QSFP-to-QSFP form factor and a 3 m length that fits typical rack and adjacent-rack deployments, providing low latency and low power consumption compared with active optical modules. It is designed to be MSA-compliant and to interoperate with major networking hardware platforms that accept passive 40G direct attach twinax solutions, enabling reliable transmission of Ethernet, FCoE, Fibre Channel and InfiniBand protocols up to 40 Gbit/s. Components used in the assembly are selected to meet industry quality standards, contributing to an extended service life and stable electrical signal transfer on short distances.

Suitable for

• Short-reach rack-to-rack or intra-rack 40 Gbit/s links in data centers
• Interconnecting QSFP-enabled switches, routers and storage systems
• Environments requiring low-latency, low-power direct attach connections
• Network upgrades where MSA-compliant passive DAC cables are supported

Key specifications

• Connector type: QSFP to QSFP (male/male)
• Length: 3 metres
• Supported protocols: 40GBase-CR4 compatible; supports Ethernet, FCoE, Fibre Channel and InfiniBand up to 40 Gbit/s on short distances
• Cable type: Passive twinax copper construction suitable for direct attach use
• Wire gauge: 30 AWG (typical for 40G DAC twinax)
• Compliance: Designed to meet common MSA mechanical and electrical requirements for QSFP DACs

How to use

Install the BlueOptics 332-1363-BL by inserting each QSFP connector into the QSFP port of the respective networking device until the connector latches. Use the 3 m cable for direct attach connections between adjacent racks or within the same rack. Ensure both devices support passive 40G DAC twinax cables and the intended protocol (Ethernet, FCoE, Fibre Channel or InfiniBand). Confirm link establishment and proper speed negotiation in device management interfaces after physical connection. Handle connectors by their housing and avoid bending the cable sharply near the terminations to preserve signal integrity.

Recommendations

Use this passive QSFP-to-QSFP cable in short-distance scenarios where the host hardware explicitly supports passive 40GBase-CR4 DACs. Avoid using the cable beyond its intended 3 m range or in environments that require active optical transceivers. Store and route the cable to prevent tight bends and mechanical stress; follow your equipment vendor guidelines for hot-plugging and ESD precautions.
