## Summary description

The BlueOptics QSFP28-DAC-5M-SP is a 5-meter passive direct attach copper cable with QSFP28 connectors. It is designed for high-speed data transmission in data centers and networking applications. This cable offers reliable performance and low latency, making it ideal for connecting switches and servers.

## Long description

The BlueOptics QSFP28-DAC-5M-SP is a 5-meter passive direct attach copper (DAC) cable with QSFP28 male connectors at both ends, engineered for short-reach, high-speed interconnects in data center and enterprise networking environments. Designed to support 100 Gigabit Ethernet links with low latency and stable electrical performance, this cable provides a plug-and-play connection between QSFP28 ports on switches, routers, and servers without the need for transceivers.
Advantages
This passive DAC cable delivers reliable signal integrity and low power consumption compared with active optical alternatives for short distances. The QSFP28 form factor ensures mechanical compatibility with standard 100GbE ports, while the fixed 5 m length simplifies cabling layouts and reduces clutter. Being a direct attach copper solution, it offers predictable latency and cost-effective connectivity for dense rack-to-rack and intra-rack deployments.
Suitable for
 Short-reach connections between switches and servers within racks or across adjacent racks
 High-speed 100 Gigabit Ethernet links in data center topologies
 Low-latency environments such as storage networks and high-performance computing clusters
 Environments requiring cost-effective, power-efficient interconnects for QSFP28 ports
Key specifications
 Connector type: QSFP28 male to QSFP28 male
 Cable type: Passive direct attach copper (DAC)
 Length: 5 meters
 Supported data rate: Up to 100 Gbps (per cable, QSFP28 standard)
 Latency: Low, suitable for latency-sensitive links
 Form factor: QSFP28 for compatibility with standard 100GbE ports
 Typical usage: Rack-to-rack and intra-rack short-reach connections
How to use
Insert each QSFP28 connector into the corresponding QSFP28 port on your network devices until the latch engages. Confirm that ports are enabled and verify link status through device management interfaces. No additional transceivers, optical modules, or configuration is required for basic link establishment; the cable functions as a direct electrical connection. For best results, avoid sharp bends and maintain proper airflow around equipment racks to help manage heat dissipation.
Usage recommendations
Use this 5 m passive QSFP28 DAC cable for short-distance, high-bandwidth links where power efficiency and predictable latency are priorities. Verify compatibility with your switch or server vendor's supported cable lists and ensure QSFP28 port firmware is up to date to avoid any interoperability issues.
