DAC SFP+ CBO BN-SP-CBL-3M-IB 3 m Direct-Attach-kuparikaapeli SFP+-portteihin

Direct-attach copper (DAC) cable BlueOptics BN-SP-CBL-3M-IB is a 3 meter, SFP+ compatible copper twinax assembly designed for short-reach high-speed links. It connects SFP+ ports on switches, servers and storage devices to provide a low-latency 10GbE or SFP+-rated physical layer. The pre-terminated cable simplifies rack-level interconnects, eliminates the need for separate transceivers and reduces power consumption compared with optical solutions.

Advantages

This 3 m DAC cable delivers reliable electrical connectivity for SFP+ interfaces with minimized insertion loss and stable signal integrity across short distances. Being pre-terminated, it offers fast deployment without field termination or transceiver purchases. The copper twinax design provides lower latency and lower power draw than equivalent fiber-optic transceiver links while remaining cost-effective for top-of-rack and adjacent-rack connections.

Key specifications

How to use

Insert each SFP+ connector into the SFP+ port of the two devices to be linked, ensuring the connectors latch securely. Confirm both ends are compatible with SFP+ copper direct-attach connections on the host devices and check link status through device management interfaces. No additional transceivers or fiber patching are required. For hot-pluggable ports, power state and vendor compatibility guidelines from the device manufacturer should be observed.

Recommendations

Use this 3 m DAC cable for intra-rack or adjacent-rack 10GbE interconnects where a short, low-latency, power-efficient connection is required. Avoid routing across long cable runs; for distances beyond typical adjacent-rack layouts consider optical fiber solutions. Inspect connectors for contamination before insertion and avoid excessive bending near the connector strain-relief to maintain signal integrity.
