Direct Attach-kabel ALCATEL OS6560-CBL-40 QSFP+ 20GBase-CU koper 40 cm

Direct attach copper cable ALCATEL OS6560-CBL-40 with QSFP+ connectors provides a short-reach, low-latency physical link for data centers and network racks. With a 40 cm length and support for 20GBase-CU signaling, this copper DAC is intended for direct connections between compatible QSFP+-equipped switches, servers and storage systems. The design prioritizes simple, cost-effective interconnects where active optical transceivers are not required.

Advantages

This QSFP+ copper cable offers predictable latency and stable signal integrity for short-distance links, while eliminating the need for separate transceivers and fiber patch cords. The fixed 40 cm length is convenient for intra-rack and adjacent-rack connections, reducing cable clutter and simplifying cable management. Built for plug-and-play operation, it provides a lower total cost of ownership for supported network topologies.

Key specifications

How to use

Install the cable by aligning each QSFP+ connector with the corresponding port on the network device and firmly inserting until the latch engages. Use the cable for direct connections between QSFP+ ports; no additional transceivers or fiber patching is required. When removing, depress the connector latch before pulling to avoid damaging the port or cable. Verify device compatibility and port settings on both endpoints to ensure proper link negotiation and data rate alignment.

Recommendations

For reliable performance, route the 40 cm cable to avoid sharp bends and excessive stress; maintain the cable bend radius recommended by the manufacturer and avoid running the DAC alongside sources of electromagnetic interference. Confirm that both network devices support QSFP+ copper DAC operation and the 20GBase-CU standard before deployment. For densely packed installations, label both ends to simplify maintenance and replacement.
