Cavo twinax CBO SFP+ 3 m, connettore maschio-maschio, 10 Gbit/s

The CBO SFP+ Twinax Cable 3 m, Male-to-Male, 10 Gbit/s by BlueOptics is a direct-attach copper cable designed for short-reach, high-speed connections between network equipment with SFP+ ports. At 3 metres length and with SFP+ male connectors on both ends, this twinax cable supports 10 Gbit/s links with low latency and reduced power consumption compared with optical transceivers plus fibre. It is intended for use in rack-to-rack or within-rack cabling where cost-effective, reliable connectivity is required between switches, network interface cards and storage devices that accept SFP+ modules.

Advantages

This direct-attach SFP+ twinax cable provides a simple plug-and-play solution for 10 Gbit/s short-range links without the need for separate transceivers or fibre patch cords. Its copper construction offers stable signal integrity and low latency for latency-sensitive applications while keeping power usage and total cost of ownership lower than many active optical solutions. The 3 m length balances reach and reduced cable congestion in typical rack and data centre layouts. Compatibility with SFP+ ports ensures straightforward deployment with a wide range of switches and adapters that support SFP+ interfaces.

Suitable for

• Direct connections between SFP+ ports on switches and top-of-rack equipment
• Interconnecting server NICs and storage arrays within the same rack or adjacent racks
• Short-reach 10 Gbit/s links in data centres and server rooms
• Environments where low latency and reduced power consumption are required

Key specifications

• Cable type: Direct-attach twinax copper cable with SFP+ male connectors
• Data rate: 10 Gbit/s (per link)
• Length: 3 metres
• Connector type: SFP+ male on both ends
• Typical use: Short-range, within-rack or adjacent-rack interconnects
• Latency: Low, suitable for latency-sensitive applications

How to use

Install the cable by inserting each SFP+ male connector into the corresponding SFP+ port until the latch engages. Ensure both endpoints support 10 Gbit/s copper direct-attach connections and that port settings (speed, duplex, and any vendor-specific interface options) are configured per equipment documentation. For reliable operation, route the cable to avoid sharp bends and excessive tension; secure with standard cable management to prevent strain on the connectors. After insertion, verify link status and speed on both connected devices using their management interfaces or status LEDs.

Recommendations

Use this 3 m SFP+ twinax cable for short-distance links where cost-efficiency and low latency are priorities. Avoid running the cable alongside high-power electrical lines to reduce potential interference. For longer distances or when fibre is required for isolation or reduced weight, consider optical transceivers and fibre patching instead.
