InfiniBand/fibre optic cable BlueOptics 332-1662-BL 1 m QSFP Male/Male

The BlueOptics 332-1662-BL is a 1 m InfiniBand/fibre optic direct attach cable with QSFP male connectors on both ends. Designed for short-reach, high-speed links, it supports up to 40 Gbps data rates and is suitable for use in rack-to-rack and intra-rack connections in data centers and networking environments. The cable follows MSA-compatible QSFP pinouts and physical form factor for straightforward integration with switches, routers and storage systems that accept QSFP-to-QSFP direct attach solutions.

Advantages

This 1 m QSFP-to-QSFP cable provides a low-latency, low-power connection option for short-distance high-bandwidth links. As a direct attach assembly it requires no transceivers and provides a compact, simple connection with consistent signal integrity for Ethernet, FCoE and InfiniBand protocols up to 40 Gbps. The cable is manufactured to industry mechanical and electrical standards and uses quality components to offer reliable operation in densely populated rack environments.

Suitable for

• Short-reach 40 Gbps connections between switches and top-of-rack devices
• High-performance computing clusters and InfiniBand fabrics
• Storage area networks and storage-to-switch links
• Patch connections within and between adjacent server racks

Key specifications

• Connector type: QSFP male to QSFP male
• Length: 1 meter
• Data rate: up to 40 Gbps
• Cable type: direct attach (twinax/direct attach copper for short distances) compatible with QSFP 40GBase-CR4 usage
• Wire gauge (where applicable): 30 AWG
• Form factor: QSFP MSA compatible

How to use

Install the cable by aligning each QSFP male connector with the QSFP ports on the devices to be linked and insert until the connector latches. Ensure both devices support passive direct attach QSFP connections and the same 40G protocol (Ethernet, FCoE or InfiniBand). Route the cable to avoid sharp bends and mechanical stress; keep it clear of obstructing airflow in the rack. For removal, depress the connector latch and withdraw straight out to avoid damaging ports or the cable.

Recommendations

Use this 1 m BlueOptics QSFP direct attach cable for reliable short-distance 40 Gbps links where passive twinax solutions are supported. Verify device compatibility with QSFP passive DACs and follow rack cable management best practices to maintain signal integrity and ease of service.
