Description
The Zyxel DAC10G-1M is a high-performance 10G SFP+ Direct Attach Cable (DAC) engineered to meet the rigorous demands of modern data centers and enterprise networks. By integrating the SFP+ connectors directly onto a twinaxial copper cable, this solution provides a seamless 10 Gigabit Ethernet link without the power consumption or complexity of traditional optical modules. Its 1-meter length is optimized for top-of-rack (ToR) deployments, ensuring clean cable management and maximum signal integrity for critical hardware interconnects.
- Data center administrators requiring reliable top-of-rack switch-to-server connectivity.
- Small-to-medium business IT managers upgrading network backbones to 10Gbps speeds.
- Home lab enthusiasts building high-speed links between NAS storage and workstations.
- Network engineers seeking a low-latency, low-power alternative to 10GBASE-T copper.
- Budget-conscious organizations looking to reduce the Total Cost of Ownership (TCO) for short-range 10G links.
- Interface: SFP+ to SFP+ connectors
- Data Transfer Rate: 10 Gbps Full-Duplex
- Cable Type: Passive Twinaxial Copper
- Length: 1 Meter (3.28 feet)
- Compliance: SFP+ MSA (Multi-Source Agreement)
- Power Consumption: Near-zero (Passive design)
Deploying the DAC10G-1M is a straightforward experience characterized by its true plug-and-play functionality. Unlike optical solutions that require careful handling of fiber strands and separate transceiver installation, this cable is robust and ready for immediate use. Users will notice significantly lower heat dissipation compared to 10GBASE-T RJ45 modules, which contributes to better overall rack cooling and equipment longevity. The physical flexibility of the twinaxial cable allows for tight bends within server cabinets without risking signal degradation.
When compared to 10G optical transceivers, the Zyxel DAC10G-1M is significantly more affordable and energy-efficient for distances under 5 meters. While 10GBASE-T (Cat6a) cabling is common, it often suffers from higher latency and increased power draw; the DAC10G-1M bypasses these issues by using a direct electrical path. For short-range intra-rack connections, this DAC provides the lowest possible latency, making it superior for high-frequency trading or real-time data synchronization tasks where every microsecond counts.
- Does this cable require separate SFP+ transceivers to work?
No, the SFP+ connectors are permanently attached to the cable, making it an all-in-one solution.
- Is the Zyxel DAC10G-1M compatible with other brands of switches?
Yes, it follows the SFP+ MSA standard, ensuring compatibility with most networking hardware that supports standard SFP+ interfaces.
- What is the main advantage of using a DAC over a fiber optic cable?
DACs are more cost-effective for short distances and consume significantly less power than optical modules.
- Can this cable be used for 1G SFP ports?
This cable is specifically designed for 10G SFP+ ports; compatibility with 1G ports depends on whether the specific switch hardware supports dual-rate speeds.
- Is this an active or passive cable?
This is a passive DAC, which is ideal for short distances like 1 meter as it requires no active electronics to maintain signal strength.
