## Summary description

The BlueOptics QSFP28-DAC-5M-SO is a 5-meter InfiniBand/fibre optic cable with QSFP28 connectors. Designed for high-speed data transmission, it features male connectors on both ends, ensuring reliable connectivity for data centers and networking applications.

## Long description

The BlueOptics QSFP28-DAC-5M-SO is a 5-meter direct attach cable with QSFP28 connectors at both ends, engineered for high-speed InfiniBand and fibre optic networking environments. Its fixed-length copper/fibre construction supports short-reach, low-latency links between switches, servers, and storage systems where QSFP28 ports are standard. The cable combines compact form factor and industry-standard QSFP28 connectivity to simplify rack cabling and maintain consistent signal quality across data center and telecom installations.
Advantages
The cable provides reliable, high-bandwidth connections using QSFP28 interfaces, enabling data rates commonly used in InfiniBand and 100GbE environments. With a 5 m length it offers sufficient reach for inter-rack and intra-rack connections while minimizing excess slack. The male-to-male QSFP28 terminations ensure straightforward mating with QSFP28 ports without the need for adapters. The product is designed to deliver consistent electrical performance and predictable latency for latency-sensitive applications.
Suitable for
Short-reach connections between switches and servers in data centers
High-performance computing clusters using InfiniBand fabrics
Interconnects for storage systems and aggregation switches
100 Gigabit Ethernet links where QSFP28 ports are available
Key specifications
Connector type: QSFP28 male on both ends
Cable length: 5 meters
Application: InfiniBand and 100GbE-compatible short-reach links
Form factor: Direct attach cable (DAC) suitable for QSFP28 ports
Performance: Designed for high-bandwidth, low-latency connections
How to use
Inspect QSFP28 ports on both devices to ensure they are clean and free of debris. Align each male QSFP28 connector with the port and insert straight until the connector latches. Avoid excessive bending of the cable near the connectors; maintain the manufacturer’s minimum bend radius to preserve signal integrity. When removing the cable, release the latch mechanism before pulling the connector straight out to prevent damage to the port and plug.
Usage recommendations
For optimal performance, use the BlueOptics QSFP28-DAC-5M-SO in short-reach scenarios within racks or between adjacent racks. Keep cable runs tidy with appropriate routing and strain relief, and verify compatibility with host interfaces and switch firmware to ensure proper link negotiation and speed.
