Καλώδιο άμεσης σύνδεσης χαλκού LevelOne DAC-0103 10 Gbit/s SFP+ 3 m Twinax

The LevelOne DAC-0103 Direct Attach Copper Cable is a 3 m SFP+ twinax assembly designed for 10Gbps Ethernet and 10G Fibre Channel short-reach connections. With SFP+ connectors on both ends and a twinax construction, this cable provides high signal integrity and low latency for data centres, server-to-switch links and other high-performance networking equipment. It is a passive, hot-pluggable solution that meets SFP+ MSA and improved pluggable form factor (IPF) expectations for EMI/EMC performance.

Advantages

The cable supports multi-gigabit data rates up to 10.5 Gbps while remaining backward compatible to 1 Gbps. Its SFP+ 20-pin hot-pluggable footprint and twinax design enable high port density and reduced power consumption compared with optical transceivers. The assembly is RoHS compliant and rated for operation in the 0–70 °C temperature range.

Suitable for

• Server-to-switch and switch-to-switch short-reach connections
• 10GbE and 10G Fibre Channel links within racks or across adjacent racks
• Data centre and high-performance computing equipment requiring low-latency interconnects

Key specifications

• Data rate: up to 10.5 Gbps (backward compatible to 1 Gbps)
• Length: 3 m
• Connector: SFP+ (20-pin) twinax, hot-pluggable
• Form factor compliance: SFP+ MSA, Improved Pluggable Form Factor (IPF)
• Operating temperature: 0 to 70 °C
• RoHS: compliant

How to use

Insert each SFP+ connector into the appropriate SFP+ slot on the networking devices until the module latches. Verify link status on both devices and configure interface settings (speed/duplex or auto-negotiation) according to the equipment documentation. For reliable performance, avoid tight bends and mechanical strain on the twinax cable and ensure connectors remain free of debris before insertion.

Recommendations

Use this passive 3 m DAC for short-distance 10Gbps interconnects inside racks or between adjacent racks; for longer spans or where galvanic isolation is required, choose optical transceivers and fibre cabling.
