SFP+ DAC cable CBO F5 F5-UPG-SFPC+-3M, 3 m length, direct-attach copper

Direct-attach copper (DAC) SFP+ cable CBO F5 F5-UPG-SFPC+-3M is a 3 meter passive twinax cable designed for high-speed 10GbE interconnects. Intended for short-reach links between switches, servers and network interface cards, this SFP+ direct-attach copper cable provides a low-latency, energy-efficient and cost-effective physical connection where SFP+ ports are available. The cable supports typical rack-to-rack and within-rack deployments in data centers and server rooms and is compatible with equipment that accepts standard SFP+ passive copper modules.

Advantages

The direct-attach copper design eliminates the need for separate optical transceivers, reducing per-link cost and simplifying inventory. With a fixed 3 m length, the cable offers predictable signal integrity and low latency for short-reach 10GbE links. Passive construction results in low power consumption compared with active optical solutions. The SFP+ form factor ensures plug-and-play operation in devices that support standard SFP+ passive copper modules.

Key specifications

How to use

Insert each SFP+ connector into the corresponding SFP+ port on the two devices to be connected until the latch engages. Ensure both devices are powered and configured for 10GbE operation; most systems will recognize passive SFP+ copper modules automatically. Route the 3 m cable to avoid sharp bends and mechanical strain, and secure it to prevent accidental disconnection. Verify link status and negotiated speed in the switch or host interface once connected.

Recommendations

Use this passive SFP+ DAC cable for short-distance 10GbE links where both ends support standard SFP+ passive copper modules. Avoid prolonged exposure to excessive mechanical stress, and maintain bend radii recommended for twinax cables. For longer distances or fiber-based topologies, consider optical transceivers and fiber cabling instead.
