Cisco 10GBase-cu SFP+ kábel 5 metrov náhradný

The Cisco 10G Direct Attach Twinax SFP+ Cable is a passive 10 Gigabit Ethernet twinax copper assembly with SFP+ connectors on both ends and a fixed length of 5 m. Designed for short-range links inside racks and between adjacent racks, this cable provides a low-latency, direct attach option for connecting switches, servers and storage devices. The 30AWG conductor gauge and factory-tested construction deliver consistent electrical performance for 10GBASE-CR applications while the black jacket matches standard data centre cabling aesthetics. The product is covered by Cisco's standard warranty policy.

Advantages

This direct attach twinax cable offers low latency and low power consumption compared with active optical or active copper alternatives, because it is a passive assembly that does not require additional transceivers or power. The integrated SFP+ connectors provide a simple plug-and-play installation with broad compatibility in equipment that accepts SFP+ modules. With a 5 m length and 30AWG construction, the cable is optimized for short-reach, high-throughput links while reducing clutter and cost compared to using separate transceivers and fiber patch cords.

Suitable for

• 10 Gigabit Ethernet connections between top-of-rack and end-of-row switches
• Direct server-to-switch links in data centre racks
• Interconnects between storage arrays and host adapters
• Short-range links in enterprise server rooms and lab environments

Key specifications

• Transmission speed: 10 Gbps
• Cable type: Passive twinax copper
• Conductor gauge: 30 AWG
• Connector type: SFP+ to SFP+
• Length: 5 m
• Colour: Black
• Application: Short-reach 10GBASE-CR direct attach

How to use

Install the cable by inserting each SFP+ connector into the corresponding SFP+ port on the network devices until the latch engages. Confirm the physical link LEDs on both devices indicate a stable connection and check device interfaces for a negotiated 10 Gbps link speed. The cable requires no configuration and does not contain active electronics; handle the assembly by the connector bodies and avoid sharp bends or kinks in the twinax cable to maintain signal integrity.

Recommendations

Use this passive 5 m Direct Attach Twinax SFP+ Cable for short-distance 10 Gbps links within racks or between adjacent racks. Keep bend radius within manufacturer guidelines, avoid running the cable alongside high-power electrical lines for long stretches, and verify compatibility with your switch or server vendor's supported cable/DMU list to ensure full interoperability.
