BlueOptics 6CNM4-BL InfiniBand fibre optic cable 2 m QSFP28 Male Male

The BlueOptics 6CNM4-BL InfiniBand fibre optic cable is a 2 m high-speed connection with QSFP28 male-to-male connectors. Designed for short-reach links in data centres and network racks, this cable supports 100G-class data transmission and provides a compact direct attach solution where InfiniBand and Ethernet-compatible high-bandwidth connectivity is required.

Advantages

The 2 m length and QSFP28 to QSFP28 connector configuration enable straightforward rack-to-rack or within-rack connections while minimising cable clutter. The cable is compatible with common hardware platforms that accept QSFP28 direct attach connections and is manufactured to industry mechanical and electrical interface standards to ensure reliable high-throughput performance. Passive twinax construction keeps power consumption and latency low for short-distance interconnects.

Suitable for

• Short-reach links between switches and servers within racks
• High-bandwidth InfiniBand or 100G Ethernet connections
• Data centre uplinks and top-of-rack cabling
• Storage and SAN interconnects supporting QSFP28 ports

Key specifications

• Connector type: QSFP28 male to QSFP28 male
• Length: 2 metres
• Application: InfiniBand and 100G-class data transmission
• Cable type: passive direct attach (twinax) suitable for short distances
• Typical use case: within-rack and adjacent-rack high-speed interconnects

How to use

Insert each QSFP28 connector into compatible QSFP28 ports on the devices to be linked, ensuring proper alignment and firm seating until the connector latch engages. Use the 2 m length for connections inside racks or between adjacent racks where a passive direct attach twinax solution is appropriate. Verify that the connected equipment supports passive QSFP28 direct attach cables and that the port firmware and vendor compatibility requirements are met before deployment.

Recommendations

Handle the cable by the connector housings and avoid excessive bending or twisting of the cable assembly. Keep the cable route clear of sharp edges and maintain minimum bend radius as specified by the equipment manufacturer. Confirm compatibility with your switch, server or storage platform and, where available, test a sample connection to validate link performance before wide deployment.
