DAC kábel CBO, kompatibilný s Palo Alto Networks SFP28-DAC-2M, direct attach copper, dĺžka 2 m

BlueOptics CBO compatible DAC cable for Palo Alto Networks SFP28-DAC-2M is a 2-meter direct attach copper cable engineered for short-reach 25 Gigabit Ethernet links. The cable connects SFP28 ports in switches, routers and firewalls to provide a low-latency, energy-efficient physical link suited to top-of-rack and rack-to-rack interconnects in data centers and network closets. It delivers a compact, pre-terminated solution that eliminates the need for transceivers and simplifies cabling for dense equipment layouts.

Advantages

This direct attach copper cable offers low latency and reduced power consumption compared with optical alternatives, while maintaining the signal integrity required for 25GbE traffic. Its fixed 2 m length provides predictable signal performance for short runs and helps manage cable routing in crowded racks. The pre-terminated SFP28 interfaces allow plug-and-play installation and compatibility with SFP28 ports that accept DAC assemblies, enabling cost-effective, high-throughput connections without additional modules.

Suitable for

• Top-of-rack switch to switch connections within the same rack
• Rack-to-rack interconnects in adjacent cabinets
• Direct links between switches, routers and firewalls with SFP28 ports
• Short-reach 25GbE links in data centers and network closets

Key specifications

• Connector type: SFP28 compatible direct-attach copper
• Cable type: Shielded copper twinax
• Maximum data rate: 25 Gigabit Ethernet
• Length: 2 meters
• Typical use: Short-reach interconnects (top-of-rack, rack-to-rack)
• Latency: Low, suitable for high-throughput applications

How to use

Ensure both devices have SFP28 ports that accept DAC assemblies and that firmware or port settings permit direct-attach connections. Insert each SFP28 connector into the corresponding port until it latches, verify link LEDs or management interfaces for an active 25GbE link, and secure cable routing to avoid sharp bends or mechanical strain. For removal, depress the latch and pull the connector straight out to prevent damage to the port or cable.

Recommendations

Use the 2 m DAC cable for short, point-to-point connections within racks or between adjacent racks; avoid using it for runs longer than the specified length. Maintain proper airflow and avoid tightly bundling cables to minimize heat accumulation. Verify compatibility with your device vendor’s supported DAC lists if hardware-level interoperability is required.
