## Summary description

The BlueOptics QSFP28-DAC-0.5M-SO is a 0.5 meter InfiniBand fibre optic cable with QSFP28 connectors. It features a male-to-male configuration, ensuring reliable high-speed data transmission for data centers and networking applications.

## Long description

The BlueOptics QSFP28-DAC-0.5M-SO InfiniBand fibre optic cable 0.5m Male/Male is a short-distance direct attach cable designed for high-density networking environments. With QSFP28 connectors at both ends, this 0.5 meter cable supports high-speed data transmission suitable for InfiniBand and compatible switching equipment. Its compact length and male-to-male configuration make it suitable for connecting adjacent ports within racks, top-of-rack switches, and direct server-to-switch links.
Advantages
This BlueOptics QSFP28 direct attach cable delivers low-latency, high-throughput connectivity for short-reach applications. The fixed 0.5 m length minimizes cable clutter and signal loss in dense installations. Built for reliable mechanical fit and electrical performance, the male-to-male QSFP28 connectors ensure secure mating with compatible ports, reducing the risk of intermittent connections. The assembly is intended to provide consistent signal integrity for InfiniBand environments that require tight port spacing and predictable latency characteristics.
Suitable for
Server-to-switch and switch-to-switch connections in data center racks
High-performance computing clusters using InfiniBand interconnects
Top-of-rack and middle-of-row short-reach cabling
Environments requiring minimal cable slack and neat cable management
Key specifications
Connector type: QSFP28 male to QSFP28 male
Length: 0.5 meter
Compatible protocol: InfiniBand (high-speed serial interfaces)
Application: Short-reach direct attach for rack-mounted equipment
Design: Low-latency, high-throughput direct attach cable
How to use
Identify the QSFP28 ports on your devices and align each male QSFP28 connector with the port opening. Insert the connector straight into the port until it seats securely; do not force the connector if resistance is felt. Ensure both ends are fully engaged to establish the electrical link. Route the 0.5 m cable to avoid sharp bends and interference with airflow inside the rack. For removal, press the connector latch or release mechanism and pull the connector straight out without twisting to prevent damage to the connector or port.
Usage recommendations
Use this cable for short-distance, high-bandwidth connections where low latency and compact routing are required. Avoid exceeding the intended bend radius, and keep the cable clear of sources of electromagnetic interference. Verify port compatibility and firmware requirements on networking equipment before deployment.
