Network Cable BlueOptics 980-9I54H-00V00A QSFP56 DAC 0.5M Blue

The BlueOptics 980-9I54H-00V00A QSFP56 DAC 0.5M Blue is a direct attach copper cable engineered for short-reach, high-bandwidth interconnects in modern network environments. At 0.5 meters length, this QSFP56 passive direct attach cable provides a low-latency physical link between compatible QSFP56 ports, enabling reliable 200G-capable connections where supported by equipment. The cable's blue jacket aids visual identification in dense rack and patching setups while its compact form factor reduces cabling clutter in data centers and server rooms.

Advantages

This QSFP56 DAC offers stable electrical performance with minimal power overhead compared with active optical transceivers for equivalent short-distance links. Its short 0.5 m length minimizes signal attenuation and latency, making it suitable for top-of-rack and adjacent-rack connections. The robust outer jacket and factory-terminated connectors ensure consistent contact and reduced risk of physical damage during installation and maintenance.

Suitable for

• Top-of-rack server to switch connections in data centers
• High-density switch-to-switch links in enterprise networks
• Short-reach interconnects inside server cabinets and network racks
• Environments requiring easy visual identification of cabling

Key specifications

• Connector type: QSFP56 to QSFP56
• Length: 0.5 meter
• Supported interface: Direct attach copper (DAC)
• Data rate capability: compatible with 200G-capable QSFP56 ports (device support dependent)
• Color: blue jacket for visual identification
• Form factor: compact, factory-terminated cable assembly

How to use

Insert each QSFP56 plug into the corresponding port on your networking devices until the connector latches securely. Ensure both devices support QSFP56 DAC connections and the intended data rate. Route the 0.5 m cable to avoid sharp bends or tension; maintain the cable bend radius recommended by the equipment manufacturer. When removing the cable, depress the latch mechanism and pull straight out to avoid damaging the connector.

Usage recommendations

Use this short QSFP56 DAC for intra-rack and adjacent-rack connections where low latency and minimal power draw are priorities. Verify compatibility with the network equipment vendor's supported transceiver and DAC lists before deployment, and avoid exposure to excessive heat or mechanical stress to prolong service life.
