BlueOptics 60176-BL InfiniBand/fibre optic cable 1 m QSFP Male/Male

The BlueOptics 60176-BL InfiniBand/fibre optic cable is a 1 m QSFP Male-to-Male connection designed for high-speed data transmission in data centers and networking environments. It implements a QSFP-to-QSFP interface and is intended for short-range links between rack-mounted devices where a 40GBase-CR4 or equivalent 40 Gbps direct attach solution is required. The cable supports common protocols such as Ethernet, Fibre Channel, FCoE and InfiniBand up to 40 Gbps over a 1 meter distance and is suitable for use with hardware platforms that accept QSFP passive direct attach twinax copper connections.

Advantages

This BlueOptics cable provides a compact, low-latency link with passive QSFP connectors on both ends, enabling reliable electrical signal transfer for short interconnects. As a passive direct attach twinax solution, it consumes minimal power and has a simple design that reduces failure points. Components are selected to meet MSA guidelines and common industry quality standards to ensure stable performance and long operational lifetime in rack-to-rack and within-rack deployments.

Suitable for

• Short-range connections between switches, routers and storage systems in racks
• High-speed links in top-of-rack and adjacent-rack deployments
• 40 Gbps Ethernet, Fibre Channel, FCoE and InfiniBand interconnects
• Data center environments requiring low-latency, low-power direct attach cabling

Key specifications

• Connector type: QSFP male to QSFP male
• Length: 1 metre
• Supported data rate: up to 40 Gbps
• Cable type: passive direct attach twinax copper
• Wire gauge: 30 AWG
• Compatibility: designed for hardware supporting QSFP passive DAC and 40GBase-CR4 applications

How to use

Install the QSFP connectors into compatible QSFP ports on the devices to be linked, ensuring the connectors are fully seated and latched according to the device manufacturer's instructions. Use the cable for short-distance, within-rack or adjacent-rack connections only — the passive twinax design is intended for 1 m runs. Verify that the connected hardware supports passive DAC cables and the intended protocol (Ethernet, Fibre Channel, FCoE, InfiniBand) before placing the link into production. Monitor link status indicators on the devices to confirm proper negotiation and operation.

Recommendations

Handle the cable by its connector bodies; avoid sharp bends and excessive pulling on the cable assembly. Keep the cable run short and free from tight bends to maintain signal integrity. Confirm compatibility with the network equipment vendor for passive QSFP DAC use and perform a test link where possible before deployment in critical environments.
