The BlueOptics CBL-NTWK-0956-QSFP56-3-BL 3m QSFP56 is a direct-attach copper (DAC) cable designed for short-reach, high-bandwidth connections in data centers and enterprise networks. With QSFP56 connectors at both ends and a 3-meter length, this cable supports 200 Gigabit Ethernet links between network switches, routers and servers where low latency and reliable throughput are required.

Advantages

This DAC cable provides a cost-effective and power-efficient alternative to optical transceivers for short-distance connections. Its QSFP56 male connectors ensure straightforward plug-and-play installation and stable electrical performance. The 3 m length reduces clutter while permitting flexible equipment placement in racks and cabinets.

How to use

Power off or follow hot-plug guidelines of your network equipment before connecting the BlueOptics QSFP56 DAC if required by the device vendor. Align each QSFP56 connector with the corresponding port and insert until the connector latches. Verify link status on the equipment management interface and check that the negotiated 200 Gbit/s link is active. To remove, disengage any latch mechanism and pull the connector straight out to avoid damaging the port.

Recommendations

Use this DAC cable for short interconnects within a rack or to neighboring racks; avoid routing it across long spans where signal integrity could be affected. Maintain proper bend radius and avoid sharp kinks. Confirm compatibility with your switch or server vendor for QSFP56 DAC modules and verify firmware or port settings as needed to enable 200 Gigabit Ethernet operation.
