InfiniBand/fibre optic cable BlueOptics 10414-BL 5 m QSFP28 Male/Male

The BlueOptics 10414-BL is a 5 m InfiniBand/fibre optic cable with QSFP28 male connectors on both ends. Designed for high-speed links in data centers and networking environments, this cable supports 100G class interfaces and is intended for short-range connections between compatible QSFP28 ports. The construction follows common MSA guidelines for QSFP28 form-factor interconnects and is suitable for applications that require low-latency, high-bandwidth electrical or optical connectivity over a 5 meter distance.

Advantages

This 5 m QSFP28 Male/Male cable provides a straightforward rack-to-rack or in-rack interconnect with a single-cable connection, eliminating the need for transceivers when used in compatible hardware. The cable is built to industry component standards and is tested for interoperability with major networking platforms, offering reliable signal integrity for Ethernet, FCoE, Fibre Channel and InfiniBand protocols up to 100 Gbit/s at the specified distance. Passive twinax construction yields low power consumption and minimal latency for short-reach links.

Suitable for

• High-performance computing clusters and InfiniBand fabrics
• 100G Ethernet connections between switches and routers within or between adjacent racks
• Storage systems and SAN uplinks requiring 100G QSFP28 ports
• Short-reach data center interconnects where passive DAC or compatible QSFP28 cabling is supported

Key specifications

• Connector type: QSFP28 male to QSFP28 male
• Cable length: 5 meters
• Data rate support: up to 100 Gbit/s over a 5 m link
• Cable type: InfiniBand / direct-attach (twinax) compatible construction for short-range links
• Compliance: designed to meet QSFP28/MSA mechanical and electrical interoperability requirements
• Typical use: passive direct attach cable behavior with low power consumption and low latency

How to use

Verify that both devices have QSFP28 ports that officially support passive direct attach twinax or the same InfiniBand/100GBase-CR4 interface. With devices powered down or in a maintenance window where recommended, insert each QSFP28 end into the corresponding port until the latch engages. After connection, power on the equipment and confirm link status through device LEDs or management interfaces. For mixed vendor environments, confirm compatibility in the device documentation or by testing a sample first. When removing the cable, release the latch and pull straight to avoid stressing the connector.

Recommendations

Use this cable for short-distance links up to 5 m inside racks or between adjacent racks where passive QSFP28 direct attach cabling is supported. Do not route the cable through tight bends; maintain the manufacturer’s minimum bend radius to preserve signal integrity. For deployments that require active optical transceivers or longer distances, select an appropriate optical QSFP28 module and fiber patching solution instead.
