Καλώδιο δικτύου Extralink SFP28 DAC 25 Gbit/s, 1 m, Βύσμα/Βύσμα

The Extralink SFP28 DAC 25Gbps 1m Male/Male is a direct attach copper cable engineered for short-reach, high-bandwidth links in data center and enterprise networking environments. With SFP28 connectors on both ends and a rated throughput of 25Gbps, this 1-metre cable supports high-speed connections between switches, routers, NICs and other SFP28-compatible equipment. The compact, black jacketed design is suitable for tight rack and cabinet installations where low latency and reliable physical connectivity are required.

Advantages

This Extralink SFP28 DAC delivers a cost-effective, low-power connectivity option compared with optical transceivers for short distances. The fixed integrated connectors eliminate the need for separate transceivers and fiber patch cords, simplifying cabling and reducing component count. Built for 25Gbps operation, the cable supports stable throughput and is suitable for environments that demand consistent, high-speed links. Its 1 m length offers flexible placement inside racks while minimizing excess cable bulk.

Suitable for

• Short-reach interconnects in data centres
• Top-of-rack and adjacent-rack switch connections
• High-speed server to switch links
• Laboratory or testbench setups requiring 25Gbps copper links

Key specifications

• Data rate: 25 Gbps
• Connector type: SFP28 to SFP28 (male/male)
• Length: 1 m
• Cable type: Direct attach copper (DAC)
• Colour: Black

How to use

Install the Extralink SFP28 DAC by inserting each SFP28 connector into the corresponding SFP28 ports on networking devices until the connector latches. Verify that both devices recognise the link and configure interface settings such as speed and duplex if required by your equipment. Due to its direct attach copper design, no additional transceivers or optical modules are needed. Route the cable inside the rack to avoid sharp bends and to maintain an organised layout.

Recommendations

Use this 1 m DAC cable for short-distance connections within the same rack or neighbouring racks. Avoid repeated flexing near the connector ends, do not exceed recommended bend radius, and keep the cable clear of heat sources. Confirm compatibility with your networking equipment vendor for SFP28 copper DAC support and check interface settings after installation.
