SFP28 DAC kábel BlueOptics SFP28-DAC-1M-ZY-BL 1m SFP28 konektor samica

The BlueOptics SFP28-DAC-1M-ZY-BL is a 1 meter direct attach copper (DAC) cable with SFP28 connectors on both ends, engineered for short-reach, high-speed connectivity. It provides a straightforward, low-latency link between compatible SFP28 ports and is intended for use in data center topologies where reliable, cost-effective 25GbE interconnects are required. The cable's fixed length and pre-terminated SFP28 ends simplify installation and reduce the need for additional transceivers.

Advantages

This SFP28 DAC cable delivers predictable electrical performance for 25 Gigabit Ethernet applications while keeping power consumption low compared with optical transceivers. Its one-meter length minimizes signal degradation for short runs and helps maintain low latency between connected devices. The integrated SFP28 connectors ensure plug-and-play compatibility with standard SFP28 ports, streamlining deployment in racks and patching panels.

Suitable for

• Interconnecting SFP28 ports on switches, routers and network appliances
• Server-to-switch links in rack and shelf configurations
• Short-reach patching within data center racks and between adjacent racks
• Environments that require low-latency, high-throughput 25GbE connections

Key specifications

• Interface: SFP28 on both ends
• Length: 1 meter
• Supported data rate: 25 Gigabit per second (25GbE)
• Cable type: Direct attach copper (DAC), passive
• Typical use: Short-reach, fixed-length interconnect

How to use

Insert each SFP28 connector into the corresponding SFP28 port until the latch engages. Ensure devices are powered and support DAC cables on their SFP28 ports before connecting. After insertion, verify link status through the device management interface or status indicators. For removal, press the connector's release mechanism and gently pull the cable straight out to avoid stressing the port.

Recommendations

Use this 1m DAC cable for direct 25GbE connections where short, reliable links are needed. Avoid sharp bends and excessive pulling force, maintain proper airflow in rack environments, and confirm device compatibility with passive DACs for optimal performance.
