Network Cable BlueOptics 2CGD4 compatible BlueLAN QSFP28 DAC SC282701L1M26 1m Black

The BlueOptics 2CGD4 compatible BlueLAN QSFP28 DAC SC282701L1M26 1m Black is a Direct Attach Copper (DAC) network cable engineered for short-range, high-throughput connections. At 1 metre length and with QSFP28 support, this cable provides a low-latency, low-power physical link for equipment that uses QSFP28 ports. The cable's construction emphasizes stable signal transmission and durability for dense rack environments in data centers and enterprise networking setups.

Advantages

This DAC cable delivers high-bandwidth performance compatible with QSFP28 interfaces while avoiding the need for optical transceivers, which helps reduce power consumption and component count. Its short-length copper design minimizes latency and provides consistent electrical characteristics across the link. The 1 m length and rugged jacket make it suitable for connections inside racks or between adjacent racks where reliable, space-efficient cabling is required.

Suitable for

• Interconnects between QSFP28 ports in switches and routers within the same rack
• Short-distance connections in server cabinets and high-density network equipment
• High-bandwidth links for storage area networks (SAN) and compute clusters
• Environments where reduced power consumption and low latency are priorities

Key specifications

• Cable type: Direct Attach Copper (DAC)
• Interface support: QSFP28 compatibility for 100Gbps-class links
• Length: 1 metre
• Color: Black
• Design: Twinax copper assembly optimized for short-reach, high-speed connections
• Typical use: Short-distance, high-bandwidth interconnects in racks and cabinets

How to use

Install the cable by aligning and inserting each QSFP28 connector into the corresponding port until it seats securely. Ensure both devices are powered down or support hot-plugging per vendor guidance before insertion or removal. Verify physical port compatibility and link status on connected equipment after installation. For best performance, avoid excessive bending of the cable and route it to prevent mechanical stress or interference from power lines.

Usage recommendations

Use this 1 m DAC cable for direct equipment-to-equipment links inside racks or between adjacent racks to maintain low latency and lower power usage compared with optical transceivers. Confirm QSFP28 port compatibility with your hardware and follow vendor instructions for cable handling and hot-plug procedures.
