BlueOptics QSFP28-DAC-5M-SW InfiniBand/kuituoptinen kaapeli 5 m uros/uros

The BlueOptics QSFP28-DAC-5M-SW is a 5-meter direct-attach cable with QSFP28 connectors in a male-to-male configuration, designed for high-speed InfiniBand and fibre optic network links. It supports short-reach connections between switches, servers and network interface cards where QSFP28 ports are available. The cable is intended for data center and enterprise environments requiring reliable, low-latency connectivity over a 5 m distance.

Advantages

The cable offers a compact, factory-terminated solution that eliminates the need for separate transceivers and patch cords, simplifying rack cabling and reducing power consumption. With QSFP28 interface compatibility, it supports high bandwidth rates suitable for modern 100 Gbps infrastructures and provides consistent signal integrity for short-reach links. The male/male configuration ensures straightforward plug-and-play installation in compatible QSFP28 ports.

Suitable for

• Short-reach 100 Gbps connections between switches and routers
• Direct links between servers and network interface cards with QSFP28 ports
• Top-of-rack and middle-of-row cabling in data centers
• High-performance computing (HPC) and InfiniBand clusters requiring low latency

Key specifications

• Connector type: QSFP28 male to QSFP28 male
• Cable length: 5 meters
• Application: InfiniBand and fibre optic short-reach links
• Data rate: compatible with 100 Gbps QSFP28 interfaces
• Form factor: direct-attach copper/fibre hybrid (DAC for short-range)

How to use

Ensure both devices have compatible QSFP28 ports and are powered down or support hot-plugging per vendor guidance. Align the QSFP28 connector keys and gently insert the plugs into the ports until they latch. For removal, release the latch before pulling the connector straight out. Route the cable to avoid sharp bends and secure it to prevent strain on the connectors. Verify link status on connected devices and consult system logs or port LEDs to confirm a successful connection.

Recommendations

Use this 5 m QSFP28 direct-attach cable for short-distance, high-bandwidth links inside racks or between adjacent racks. Maintain bend radius recommendations, avoid exposure to liquids or excessive heat, and follow equipment vendor compatibility lists to ensure reliable operation.
