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

The BlueOptics QSFP28-DAC-5M-AT-BL InfiniBand fibre optic cable 5m Male/Male is a 5-metre QSFP28 direct attach cable designed for short-range, high-speed interconnects in data centers and networking racks. It provides a direct QSFP28-to-QSFP28 connection supporting up to 100G data rates and is intended for linking switches, servers and storage systems that accept QSFP28 direct attach twinax solutions. The cable follows MSA-compliant electrical and mechanical specifications to ensure interoperability with major hardware platforms that support QSFP28 100GBase-CR4 and InfiniBand protocols.

Advantages

The cable offers a passive twinax design with low latency and low power consumption suitable for short-distance links. Being manufactured to MSA standards, it is compatible with a wide range of networking equipment and supports multiple protocols including Ethernet, Fibre Channel and InfiniBand at up to 100G. High-quality components and manufacturing processes are used to provide stable signal integrity and extended service life for rack-to-rack and in-rack connections.

Suitable for

• Top-of-rack and adjacent-rack connections in data centres
• Interconnecting QSFP28 ports on switches, routers and network appliances
• High-performance server-to-storage links and InfiniBand fabrics
• Short-reach 100GBase-CR4 and other 100G applications

Key specifications

• Connector type: QSFP28 male to QSFP28 male
• Length: 5 metres
• Cable type: passive twinax copper direct attach cable
• Data rate support: up to 100 Gbit/s per link (100GBase-CR4 / InfiniBand compatible)
• Wire gauge: 26 AWG
• MSA-compliant electrical and mechanical interface
• Intended use: short-range, direct attach rack/inter-rack connections
• Typical power consumption: very low (passive cable)

How to use

Connect each QSFP28 male plug to the corresponding QSFP28 port on the devices you wish to interconnect. Ensure both devices support passive QSFP28 direct attach twinax cables and the intended transmission protocol (for example 100GBase-CR4 or InfiniBand). Route the cable to avoid sharp bends and mechanical stress; maintain recommended bend radius and secure the cable within the rack to prevent strain on connectors. No additional power or transceivers are required for passive operation.

Recommendations

Confirm hardware compatibility and port settings in the device firmware or management interface before deployment. For best signal integrity, use this 5m passive QSFP28 twinax cable for short-reach links inside racks or between adjacent racks; for longer distances, consider active DACs or optical transceivers with appropriate fibre cabling.
