## Summary description

The BlueOptics NDAAFJ-0004-BL is a 5 m InfiniBand/fibre optic cable featuring QSFP28 connectors on both ends. Designed for high-speed data transfer, this cable ensures reliable connectivity in data centers and networking environments. Its male-to-male configuration makes it suitable for various applications requiring efficient data transmission.

## Long description

The BlueOptics NDAAFJ-0004-BL is a 5 m InfiniBand/fibre optic cable with QSFP28 connectors on both ends. Designed for short-range, high-speed interconnects, the cable implements a QSFP28-to-QSFP28 direct attach format suitable for 100G applications. The passive twinax construction with 26 AWG conductor size supports electrical signal transmission over a 5 m distance and is compatible with equipment that accepts QSFP28 passive direct attach cables.
Advantages
This QSFP28 male-to-male cable provides a compact, low-latency physical link for rack-to-rack and within-rack connections. As a passive direct attach twinax cable it consumes minimal power, has low insertion loss and predictable electrical characteristics, and requires no additional transceivers or active components. The cable is manufactured to MSA-compliant specifications and uses high-quality components to support sustained performance and long service life in data center environments.
Suitable for
Interconnecting QSFP28 ports on switches and routers in the same rack or adjacent racks
High-speed links for storage systems and server clusters
InfiniBand, Ethernet (100GBase-CR4) and Fibre Channel applications within a 5 m reach
Key specifications
Cable length: 5 meters
Connector type: QSFP28 to QSFP28, male/male
Data rate support: up to 100 Gbit/s (100GBase-CR4 and compatible protocols)
Cable type: passive twinax copper direct attach cable (DAC)
Conductor gauge: 26 AWG
Form factor: MSA-compliant QSFP28 direct attach
How to use
Connect each QSFP28 plug to the corresponding QSFP28 ports on the network devices, ensuring the connectors are fully seated and latches engage. Use this cable for short-distance electrical interconnects where the devices explicitly support passive QSFP28 direct attach cables. Verify link status on both devices after connection and confirm that the network interfaces are configured for the chosen protocol and speed.
Usage recommendations
Avoid tight bends and maintain the manufacturer’s minimum bend radius. Use the cable in temperature-controlled data center environments and keep it clear of sharp edges and moving parts. For compatibility, confirm the target hardware vendor’s support for passive QSFP28 DACs before deployment.
