Direct Attach Copper (DAC) SFP+ cable CBO SFN8400-3 30m, compatible, BlueLAN SC353501J3M30

Direct Attach Copper (DAC) SFP+ cable CBO SFN8400-3 30m is a pre-terminated copper twinax assembly designed for short-range 10GbE links. The cable plugs directly into SFP+ ports on switches, servers or network interface cards (NICs), delivering a low-latency, high-bandwidth connection without separate optical transceivers. With a 30 metre length and a factory-terminated SFP+ form factor, this compatible cable is intended for rack-to-rack and intra-rack interconnects in data centres and network rooms where reliable, cost-effective 10 Gigabit Ethernet connectivity is required.

Advantages

The DAC SFP+ cable offers a simplified installation process by eliminating the need for separate transceivers, reducing both component count and power consumption. As a copper-based solution it provides predictable latency and stable signal integrity over its intended short-range distance. Its pre-terminated SFP+ connectors ensure plug-and-play deployment and minimize configuration time when connecting switches, servers or NICs with matching ports.

Suitable for

• 10 Gigabit Ethernet links between switches in the same rack or adjacent racks
• Server-to-switch connections in data centres and server rooms
• Short-range uplinks and aggregation links in campus or enterprise networks
• High-density rack deployments where lower power and simplified cabling are preferred

Key specifications

• Interface: SFP+ to SFP+ direct attach copper (twinax)
• Data rate: 10 Gbps full duplex
• Length: 30 metres
• Cable type: Shielded twinax copper
• Connector: Pre-terminated 10G SFP+ connectors on both ends
• Latency: Low, suitable for low-latency network segments
• Use case range: Short-range / intra-rack and rack-to-rack interconnects

How to use

Insert each SFP+ connector into the corresponding SFP+ port on your switch, server or NIC until the connector latches. Ensure both ends are seated correctly and visible link/activity LEDs indicate a connection. No separate transceivers, fibre patch cords or additional configuration are normally required; the device will negotiate the 10GbE link automatically if the ports support SFP+ copper modules. When removing the cable, press the connector latch and pull straight out to avoid damaging the port.

Usage recommendations

Verify that your network equipment supports SFP+ direct attach copper modules and check vendor compatibility notes if available. Route the cable to avoid sharp bends and mechanical stress; maintain minimum bend radius as recommended for shielded twinax cables. For predictable performance, use this DAC cable within the specified short-range distances and in environments with proper ventilation to avoid excessive heat around connectors.
