## Summary description

The BlueOptics QSFP28-DAC-5M-QN is a 5-meter DAC cable with QSFP28 connectors on both ends. It is designed for high-speed data transfer in data centers and networking applications. This cable provides a reliable connection with low latency and high bandwidth, making it ideal for InfiniBand and fibre optic networks.

## Long description

The BlueOptics QSFP28-DAC-5M-QN is a 5-meter direct attach copper (DAC) cable with QSFP28 connectors on both ends, designed for high-speed, short-reach interconnects in data centre and enterprise networking environments. It supports 100 Gigabit link speeds via a four-lane electrical interface and is intended for use where low latency and stable, high-bandwidth connections are required. The cable's fixed length and connector type simplify rack-to-rack or switch-to-server connections without the need for transceivers.
Advantages
This QSFP28 DAC cable offers predictable performance with minimal signal modulation and very low latency compared with active optical solutions for short distances. The all-in-one passive copper assembly delivers power-efficient operation and consistent throughput over the specified 5 m reach. Its QSFP28 form-factor ensures compatibility with QSFP28 ports, enabling straightforward integration into existing 100GbE and InfiniBand infrastructures while eliminating the need for separate pluggable optics and transceivers.
Suitable for
 Short-reach 100 Gigabit Ethernet interconnects between switches, routers, and servers
 High-performance computing and InfiniBand clusters requiring low-latency links
 Top-of-rack and cross-rack cabling in data centres
 Connections where power efficiency and fixed-length reliability are priorities
Key specifications
 Connector type: QSFP28 to QSFP28 (male/male)
 Length: 5 meters
 Supported link speed: 100 Gbit/s (four active lanes)
 Physical medium: Direct attach copper (DAC)
 Typical use: Short-reach interconnects within racks and between adjacent racks
How to use
Insert each QSFP28 connector into the corresponding QSFP28 port on networking equipment, ensuring the latch engages securely. Cable handling should avoid sharp bends and excessive twisting; maintain a minimum bend radius recommended for DAC assemblies to preserve signal integrity. The cable is plug-and-play with standard QSFP28 ports; no additional transceiver modules or configuration is required for physical link establishment, though network equipment may need appropriate port configuration for intended protocols (100GbE, InfiniBand).
Usage recommendations
The cable is recommended for short-distance, high-bandwidth connections up to 5 m inside racks or between adjacent racks. Avoid using this DAC cable for extended distances beyond its specified reach or in environments where repeated flexing, high vibration, or exposure to moisture are present. When installing multiple cables, route them to prevent excessive strain on connectors and to maintain airflow in the rack.
