Direct Attach Cable CBO SFP+ SFP-10G-DAC-0.5M-F1 0.5 m Passive 10Gbps

Passive 0.5 m SFP+ direct attach cable by BlueOptics, model SFP-10G-DAC-0.5M-F1, provides a fixed-length copper connection supporting 10Gbps data rates between SFP+ ports. Engineered for short-reach interconnects, this 0.5 metre DAC is intended for use in switch-to-switch, server-to-switch and server-to-storage links where low latency and reduced power consumption are priorities. The compact, low-profile design simplifies cable management in rack and top-of-rack installations while eliminating the need for separate transceivers.

Advantages

The passive direct attach cable offers native 10Gbps performance with minimal added latency and no additional power draw from active optics. Its fixed 0.5 m length ensures predictable signal characteristics and simplified planning in dense rack environments. The integrated SFP+ connectors reduce component count and deliver a plug-and-play installation that is compatible with equipment supporting SFP+ direct attach copper connections. The small form factor supports improved airflow and cleaner cable routing in crowded chassis or patch panels.

Suitable for

• Top-of-rack and middle-of-row switch interconnects
• Short server-to-switch and server-to-storage links
• High-density data centre and lab environments requiring low-latency connections
• Environments where reduced power consumption and compact cable routing are desired

Key specifications

• Connector type: SFP+ direct attach (fixed integrated connectors)
• Length: 0.5 m
• Data rate: 10 Gbps
• Design: Passive copper twinax cable
• Typical use-case: Short-reach interconnects for switches, servers and storage

How to use

Install by inserting each SFP+ connector into the corresponding SFP+ port on the networking devices until the latch engages. Ensure both endpoints support passive SFP+ direct attach copper connections and that the port configuration on switches or servers is set for 10Gbps operation. Avoid sharp bends and ensure the cable length is appropriate for the intended rack layout. No additional configuration is typically required beyond standard port enabling and link verification.

Recommendations

For reliable operation, use this 0.5 m passive DAC within short-reach environments and ensure compatible SFP+ ports are enabled on both devices. Maintain bend radius recommendations from equipment vendors, avoid exposing the cable to excessive heat or mechanical stress, and verify link speed and duplex settings after installation.
