DAC Cable BlueOptics DAC-3M 3m SFP+ Male to SFP+ Male Black

The BlueOptics DAC-3M 3m SFP+ Male to SFP+ Male Black is a 3-meter Direct Attach Copper (DAC) cable designed for high-speed, short-reach connectivity in data center and enterprise network environments. It has SFP+ connectors on both ends to support 10 Gigabit Ethernet and other SFP+ compatible interfaces, offering a low-latency, cost-effective solution for interconnecting switches, routers and servers. The cable's 3 m length and durable black jacket make it suitable for rack-to-rack and intra-rack connections where fixed, reliable copper links are preferred.

Advantages

The DAC-3M provides low latency and stable electrical performance typical of direct-attach copper connections, with no separate transceivers required on either end. Its pre-terminated SFP+ male connectors simplify installation and reduce component count compared with optical cabling. The 3 m length supports common data center layouts while the compact cable weight and flexible jacket ease cable management in dense rack environments.

How to use

Install the DAC-3M by inserting each SFP+ connector into the corresponding SFP+ port on your networking devices until the connector latches. Ensure both devices are powered and configured to use the SFP+ interfaces. Because the cable uses pre-terminated SFP+ ends, no additional transceivers or fiber patching are required. Route the cable to avoid sharp bends and secure it according to your rack cable management practices.

Recommendations

For reliable operation, use the DAC-3M for short-reach connections within racks or between adjacent racks, keep bend radius within manufacturer guidelines, and verify compatibility with your switch or server SFP+ ports. Avoid exposure to excessive heat or mechanical strain to maintain signal integrity.
