CBO BlueOptics QSFP28 5m Male-to-Male 100 Gbit/s Turquoise optical cable

CBO BlueOptics QSFP28 5m Male-to-Male 100 Gbit/s Turquoise optical cable is a fixed-length direct-attach cable designed to establish a 100 Gbit/s short-reach link between QSFP28 ports. With a 5 metre length and QSFP28 male connectors at both ends, this turquoise-coloured cable provides a compact, low-latency physical connection for high-bandwidth server, switch and network interface applications in data centre and enterprise environments.

Advantages

The cable offers a simple plug-and-play solution for 100 Gbit/s interconnects with minimal configuration. Its fixed 5 m length reduces cable management complexity and maintains consistent signal integrity over short distances. The direct-attach design eliminates the need for separate transceivers, lowering power consumption and reducing equipment footprint. Colour coding helps quick identification in dense patching environments.

Suitable for

• Short-reach 100 Gbit/s links between switches and routers
• Connections between servers and network interface cards (NICs)
• Top-of-rack and leaf-spine data centre interconnects
• High-density rack environments requiring structured cable routing

Key specifications

• Connector type: QSFP28 male to QSFP28 male
• Nominal data rate: 100 Gbit/s
• Length: 5 metres fixed
• Cable type: direct-attach optical (fixed-length DAC-style)
• Colour: turquoise for visual identification
• Use case: short-reach, low-latency interconnect

How to use

Ensure both network devices support QSFP28 ports and 100 Gbit/s links. Power down or follow hot-swap procedures recommended by the device manufacturers before inserting the connectors if required. Align and insert each QSFP28 male connector fully into the corresponding port until it latches. Verify link status on connected devices and configure link aggregation or interface settings as needed through network management tools. For removal, release the connector latch and pull straight out to avoid stressing the cable ends.

Recommendations

Route the cable to avoid tight bends and mechanical strain; maintain manufacturer-recommended bend radii. Use colour-coded organisation and secure routing in high-density racks to simplify maintenance. Avoid exposure to excessive heat sources and sharp edges. For compatibility, confirm device QSFP28 support and firmware interoperability before deployment.
