InfiniBand/fibre optic cable BlueOptics 40GB-C01-QSFP-EN-BL 1 m QSFP Male/Male

The BlueOptics 40GB-C01-QSFP-EN-BL is a 1 m InfiniBand/fibre optic direct attach solution with QSFP Male-to-Male connectors designed for high-speed short-reach links in rack and adjacent-rack environments. It supports up to 40 Gbit/s data rates and is suitable for connecting switches, routers, and storage systems that accept QSFP-to-QSFP direct attach cabling. The cable is presented as a passive 40GBase-CR4 twinax-type connection optimized for electrical signal transfer over 1 meter and conforms to MSA-compliant QSFP form-factor expectations.

Advantages

This 1 m BlueOptics cable offers a compact, low-latency connection for high-density installations with low power consumption typical of passive direct attach twinax solutions. It is constructed to meet common MSA guidelines for QSFP 40G links and is compatible with hardware platforms that support 40GBase-CR4 and QSFP direct attach cables. The passive design reduces component complexity and contributes to a low failure rate while providing reliable point-to-point connectivity within racks.

Suitable for

• Short-reach 40 Gbit/s links between switches within a rack or to adjacent racks
• High-density data centre interconnects and top-of-rack networking
• Connecting QSFP-enabled routers, switches and storage arrays that support passive DAC cabling

Key specifications

• Connector type: QSFP Male to QSFP Male
• Length: 1 meter
• Rated data rate: up to 40 Gbit/s
• Type: passive direct attach twinax (electrical transmission)
• Cable gauge example: 30 AWG (typical for this type)
• Form factor: QSFP (MSA compliant)

How to use

Install the cable by inserting each QSFP connector into the corresponding QSFP slot on the devices to be linked, ensuring the connector latch engages. Use the 1 m length for short, direct connections inside racks or to adjacent racks. Confirm that the connected hardware supports passive 40GBase-CR4 QSFP direct attach cabling and the intended protocols (Ethernet, Fibre Channel, FCoE or InfiniBand) before placing the cable into service. Avoid twisting the cable, excessive bending beyond the manufacturer’s bend radius, or applying undue strain on the connectors while routing.

Recommendations

For best results, verify device compatibility and firmware settings for passive QSFP DAC support prior to deployment; keep the cable within recommended bend-radius limits and avoid environments with high mechanical stress or exposure to liquids to preserve signal integrity and service life.
