InfiniBand/fibre optic cable BlueOptics OS6865-CBL-100-BL 1 m QSFP Male/Male

The BlueOptics OS6865-CBL-100-BL is a 1 m InfiniBand/fibre optic direct attach cable with QSFP Male to QSFP Male connectors designed for short-range high-speed links in racks and between adjacent racks. It supports 40G data rates and is suitable for Ethernet, FCoE, Fibre Channel and InfiniBand applications where a passive 40GBase-CR4 twinax connection is required. The cable is manufactured to MSA-compliant mechanical and electrical specifications and is compatible with major hardware platforms that accept QSFP-to-QSFP direct attach twinax copper solutions.

Advantages

The cable provides low-latency, low-power passive connectivity for short-distance links with a typical power consumption near 0.1 W and simplified installation compared with active transceivers. Construction uses high-quality components and industry-standard connectors to ensure reliable signal integrity for 40G links across 1 m. Passive twinax design reduces points of failure and lowers total cost of ownership for data center top-of-rack and adjacent-rack connections.

Suitable for

• Top-of-rack and adjacent-rack 40G connections in data centers
• High-speed switches, routers and storage system interconnects supporting QSFP 40GBase-CR4
• Ethernet, FCoE, Fibre Channel and InfiniBand short-reach links up to 40G

Key specifications

• Length: 1 meter
• Connector type: QSFP Male to QSFP Male (QSFP-to-QSFP)
• Data rate support: up to 40 Gbit/s
• Cable type: passive twinax copper (40GBase-CR4 style)
• Wire gauge: 30 AWG
• MSA-compliant mechanical and electrical characteristics
• Typical power consumption: ~0.1 W (passive link)

How to use

Install the cable by inserting each QSFP connector into the corresponding QSFP port on your networking devices until the connector latches. Use for short-range links (1 m) between compatible QSFP ports on switches, routers or storage devices that support passive twinax QSFP connections. Verify that the host hardware and firmware support passive DAC cables and the intended 40G protocol (Ethernet, FCoE, Fibre Channel, or InfiniBand) before deployment. Avoid excessive bending near the connector and ensure ports are powered down or traffic is quiesced if your operational procedures require it during insertion or removal.

Recommendations

For reliability, route the cable with gentle bends only, keep it away from sources of mechanical strain and avoid tight cable bundles that could deform the twinax assembly. Confirm compatibility with your device vendor's hardware/firmware and consider requesting a test sample for validation in your environment prior to large-scale deployment.
