CBO InfiniBand direct-attach SFP+ kabel QFX-SFP-DAC-1MA-BL 1 m, passief, zwart

The CBO InfiniBand direct-attach SFP+ cable QFX-SFP-DAC-1MA-BL is a 1-meter passive copper cable designed for short-reach high-speed links between SFP+ ports on switches, servers and storage systems. This cable provides a low-latency, power-efficient physical connection without the need for separate transceivers, making it suitable for rack-to-rack and intra-rack connections in data centers, test labs and constrained cabling environments.

Advantages

This passive SFP+ direct-attach cable offers a compact and low-power alternative to optical transceivers and fiber assemblies. Its fixed 1 m length reduces signal loss and latency for short runs, while the integrated SFP+ connectors simplify installation and reduce component count. The cable’s passive design eliminates the need for local power at the transceiver ends and supports straightforward interoperability with SFP+ ports that accept direct-attach copper solutions.

Suitable for

• Short-reach server-to-switch connections within racks
• Rack-to-rack links in adjacent cabinets
• High-performance computing and InfiniBand test environments
• Cost-sensitive deployments where optical transceivers are unnecessary

Key specifications

• Connector type: SFP+ direct-attach copper twinax
• Length: 1 meter
• Cable type: Passive (no active electronics)
• Color: Black
• Application: Short-reach 10Gb+ links for InfiniBand/SFP+ ports

How to use

Insert each SFP+ connector into the corresponding SFP+ port on network equipment until the latch engages. Ensure both equipment ports are powered off or gracefully brought down according to vendor procedures before making the physical connection if required by your maintenance policy. After insertion, verify link status and speed via the devices’ management interfaces and monitor for proper negotiation. For removal, release the connector latch and pull straight out to avoid stressing the port.

Recommendations

Use this 1 m passive direct-attach cable for short, controlled paths where low latency and minimal power consumption are priorities. Avoid routing the cable near sources of electromagnetic interference and maintain reasonable bend radius to preserve signal integrity. Check vendor compatibility lists for SFP+ direct-attach copper support and confirm link settings on switches and servers to ensure proper operation.
