## Summary description

Copper Direct Attach (DAC) SFP+ cable CBO SFN8400-3, 30 meters, compatible with BlueLAN SC353501J3M30. Designed for 10GbE connections between switches, servers or NICs with SFP+ ports. Provides a pre-terminated, low-latency link without separate transceivers, simplifying installation and reducing cost for data centre and rack-to-rack short-range interconnects.

## Long description

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.
