SFP28 DAC-kabel BlueOptics SFP28-DAC-1M-UQ 1m stekker/stekker

The BlueOptics SFP28-DAC-1M-UQ is a 1 m direct attach copper (DAC) cable with SFP28 male connectors on both ends, engineered for short-reach, high-rate data links in modern network environments. Designed to provide a stable physical connection between compatible SFP28 ports, this cable supports 25 Gbit/s transmission and is suitable for interconnecting switches, routers, and server network interface cards in rack and data centre installations.

Advantages

This SFP28 DAC cable delivers low-latency, energy-efficient connectivity with minimal signal loss over short distances. Its fixed length and integrated SFP28 male connectors simplify installation and reduce the need for transceivers, lowering overall system cost and power consumption. The cable's construction provides reliable mechanical alignment and consistent electrical performance for 25G links.

Suitable for

• Short-reach 25 Gbit/s links between switches in racks
• Direct connections between servers and top-of-rack switches
• High-density data centre interconnects
• Environments requiring low-latency, low-power cabling

Key specifications

• Cable type: Direct attach copper (DAC)
• Rated data rate: 25 Gbit/s
• Length: 1 m
• Connector type: SFP28 male to SFP28 male
• Colour: Black

How to use

Ensure both devices support SFP28 passive DAC connections and that ports are powered down or follow your organisation's hot-plug guidelines. Align each SFP28 connector with the corresponding port and insert until the latch engages. Verify link status from the connected devices' management interface and check for proper 25G negotiation. For safe removal, follow the same hot-plug or shutdown procedures before releasing the connector latches.

Recommendations

Use this 1 m SFP28 DAC cable for short-distance connections inside racks or between adjacent racks. Avoid routing the cable near high heat sources, maintain bend radius recommendations from the system manufacturer, and confirm compatibility with your network equipment's SFP28 passive DAC support to ensure reliable 25G operation.
