Description

Discover the power and efficiency of high-speed networking with the Extreme Networks 100G Passive DAC QSFP28 0.5m. This compact, plug-and-play copper interconnect is designed for seamless short-reach connectivity between network devices, delivering reliable 100 Gigabit performance with minimal latency. The 0.5-meter length is perfect for tight data-center rack interconnects, enabling clean cable management, reduced signal loss, and an effortless upgrade path for spine-leaf, leaf-spine, and top-of-rack deployments. Built to the highest industry standards, this passive direct attach copper (DAC) cable provides a cost-effective, energy-efficient solution for data centers, server farms, and enterprise networks that require fast, dependable intra-data-center links. With no active components or drivers required, it’s a straightforward, dependable option for boosting network throughput while keeping operational costs in check.

  • High-speed 100G connectivity for short-reach interconnects: The QSFP28 0.5m DAC enables full 100 Gbps Ethernet across four 25 Gbps lanes, delivering the bandwidth needed for demanding workloads such as virtualization, database acceleration, and distributed computing. This cable is engineered to minimize latency and jitter, helping to preserve application performance in dense data-center environments.
  • Passive copper design for efficiency and affordability: As a passive Direct Attach Copper solution, the cable draws no power and eliminates the need for optical transceivers or external power, reducing total cost of ownership and thermal footprint. The copper construction offers a robust, reliable interconnect with excellent signal integrity over short distances, making it ideal for intra-rack and intra-closet deployments.
  • Compact, plug-and-play form factor for rapid deployments: With its 0.5-meter length, the DAC cable provides a tidy, low-profile connection between QSFP28-enabled devices such as switches, routers, and NICs. It’s designed for quick swaps and field-ready installations, enabling data-center teams to scale infrastructure quickly without complex configuration or downtime.
  • Durable build designed for data-center environments: Engineered to withstand routine rack handling, the Extreme Networks 100G DAC features robust connectors and a high-quality copper conductor to resist environmental stressors found in busy data centers. The cable’s short reach reduces cable slack and airflow disruption, contributing to improved cooling efficiency and easier cable management in dense racks.
  • Broad compatibility and practical use cases: This 100G QSFP28 DAC is suitable for Extreme Networks devices as well as other vendors’ 100G QSFP28 ports that support DAC interconnects. It’s an excellent choice for data-center spine-to-leaf layouts, top-of-rack deployments, and short inter-switch links where low latency, predictable performance, and reliable operation are essential.

How to install Extreme Networks 100G Passive DAC QSFP28 0.5m

  • Power and safety: Ensure equipment is powered down or follow your device’s hot-swap guidelines if your hardware supports hot-swapping. Handle connectors with care to avoid bending or twisting the plug during installation.
  • Prepare the ports: Locate the QSFP28 ports on your devices and verify they are intended for 100G interconnects. Confirm there are no obstructions or damage to the port area before installing the cable.
  • Align and connect: Gently align the QSFP28 plug with the port and insert firmly until the latch engages. Do not force the connector; if it resists, remove and reinsert with a straight, even motion to ensure proper contact.
  • Cable routing and management: Route the 0.5m DAC with awareness of your rack layout. Avoid sharp bends or kinks, and maintain a minimum bend radius to preserve signal integrity. Keep power cables and electrical lines separate to reduce interference and heat buildup.
  • Verify and monitor: Power up the devices and check link status indicators. Confirm that each end recognizes the 100G port and that the link shows as up. If needed, run a basic connectivity test or loopback check to confirm stable performance before placing the system into production.
  • Label and document: For easier future maintenance, label cable paths and ports, including the cable type (100G QSFP28 DAC), length, and connected devices. This practice aids troubleshooting and simplifies audits in growing data-center environments.

Frequently asked questions

  • Q: Is this DAC compatible with non-Extreme Networks devices?
    A: Yes. This is a standard 100G QSFP28 passive DAC assembly designed for short-reach interconnects. It will work with other vendors’ QSFP28 ports that support DAC interconnects, but always verify port compatibility and ensure the devices support 100G operation over DAC cables.
  • Q: What is the maximum distance of this DAC cable?
    A: The Extreme Networks 100G Passive DAC QSFP28 0.5m is specified at a length of 0.5 meters. For longer distances, optical fiber solutions are typically used to maintain signal integrity and reach.
  • Q: Does it require drivers or software?
    A: No. Passive DAC cables are plug-and-play and do not require drivers or software. They rely on standard QSFP28 ports and rely on the host device’s firmware to recognize the link.
  • Q: Is this DAC hot-swappable?
    A: In most modern data-center devices, QSFP28 ports and DAC cables are hot-swappable. Always follow your equipment manufacturer’s guidelines and power-down procedures if required by your specific hardware policy.
  • Q: What about warranty and support?
    A: Warranty terms vary by distributor and region. Check the product listing or your vendor’s support policy for the exact warranty period and coverage. In general, purchase through reputable sources to ensure legitimate support and returns.
