Network Cable BlueOptics BS33 compatible BlueLAN QSFP28 DAC SC282701L2M26 2m Blue

The BlueOptics BS33 compatible BlueLAN QSFP28 DAC SC282701L2M26 2m Blue is a 2-meter direct attach copper (DAC) cable engineered for high-speed, short-reach connections in data center and enterprise networking environments. With QSFP28 connectors and support for aggregated data rates up to 100 Gbps, this cable provides a straightforward, low-latency link between compatible QSFP28 ports on switches, routers, and network adapters. Its compact, fixed-length design simplifies rack-to-rack and chassis-to-chassis connections while minimizing power consumption compared with active optical alternatives.

Advantages

This QSFP28 DAC cable delivers consistent 100 Gbps performance with low insertion loss and predictable signal integrity for short-reach links. The passive copper construction ensures energy-efficient operation and reduced complexity—no separate transceivers or optical modules are required. The 2 m length provides flexibility for common top-of-rack and adjacent-rack connections while maintaining controlled impedance for reliable throughput. The cable is compatible with equipment that accepts QSFP28 DAC interfaces, enabling plug-and-play deployment in supported systems.

Suitable for

• High-density data center interconnects between switches and servers
• Short-reach links in high-performance computing clusters
• Direct connections between QSFP28 ports in aggregation and spine/leaf topologies
• Environments requiring low-latency, high-bandwidth links for storage and virtualization

Key specifications

• Form factor: QSFP28 direct attach copper (DAC) cable
• Length: 2 meters
• Maximum aggregated data rate: up to 100 Gbps
• Connector type: QSFP28 on both ends for compatible QSFP28 ports
• Construction: passive copper for short-reach, low-power operation
• Typical application: short-distance interconnects in racks and adjacent racks

How to use

Connect each QSFP28 plug to the corresponding QSFP28 port on your network devices, ensuring proper orientation and secure seating. Confirm that the connected devices support QSFP28 DAC connectivity and that firmware or driver settings do not restrict passive cable usage. After insertion, verify link status through device management interfaces and run any required diagnostic or performance checks to confirm 100 Gbps operation. For removal, power down or disable the port if your equipment vendor recommends it, then depress the latch and gently withdraw the connector.

Usage recommendations

Route the cable to avoid sharp bends and excessive strain; maintain the manufacturer’s minimum bend radius and avoid kinking. Use the 2 m length for planned short-reach links within racks or between adjacent racks to ensure optimal signal integrity. Ensure equipment compatibility with QSFP28 passive DAC cables and consult device documentation for supported cable types and port settings before deployment.
