Cisco 10GBASE SFP+ 2 m Active Optical Cable

Overview

The Cisco 10GBASE SFP+ 2 m Active Optical Cable is a high‑performance, direct‑attach optical solution designed for enterprise networking environments that demand reliable, low‑latency connectivity between switches, routers, and server chassis. With a compact 2‑meter length, it offers the flexibility to bridge short distances in data centers, campus LANs, or blade server configurations without the need for external power supplies.

Key Features

• 10 Gbps Data Rate: Supports 10GBASE‑SFP+ Ethernet and InfiniBand protocols, delivering double the throughput of 1 Gbps copper links.
• Active Optical Technology: Built‑in electronics convert electrical signals to optical and back again, ensuring signal integrity over short distances while eliminating the need for separate transceivers.
• 2‑Meter Length: Ideal for rack‑to‑rack or blade‑to‑blade connections where space is at a premium.
• Low Latency & Low Power Consumption: Active design consumes less than 1 W per cable, reducing overall power draw in dense deployments.
• Robust Construction: Stainless steel connectors and high‑grade fiber ensure durability against vibration, temperature swings, and electromagnetic interference.
• Plug‑and‑Play Compatibility: Fully compatible with Cisco Catalyst 3560, 3850, Nexus 93XX series, X9464, ONE Nexus 93XX, and UCS 5108 Blade Server Chassis. Works seamlessly with any SFP+ port that supports 10GBASE‑SFP+.
• Standardized Connector: Utilizes the SFF‑8431 form factor for easy integration into existing rack infrastructure.

Technical Specifications

Installation & Deployment

Deploying the Cisco 10GBASE SFP+ 2 m Active Optical Cable is straightforward:

1. Identify Compatible Ports: Locate SFP+ slots on your Cisco Catalyst or Nexus device, or UCS blade server chassis.
2. Insert the Cable: Align the SFF‑8431 connector with the port and gently push until it clicks into place. The cable’s active electronics will automatically power up.
3. Verify Link Status: Use your device’s CLI or GUI to confirm a 10 Gbps link is established. Look for “Link Up” status and a speed of 10000 Mbps.
4. Cable Management: Route the cable along rack rails, ensuring it does not bend beyond the manufacturer’s minimum radius (typically 30 mm). Secure with Velcro straps or cable ties to prevent accidental disconnection.

Best Practices

• Keep the cable within the specified temperature range to avoid signal degradation.
• Avoid excessive bending; maintain a minimum bend radius of 30 mm throughout installation.
• Use proper grounding techniques if connecting to high‑voltage equipment to mitigate EMI.
• Label cables clearly with device names and port numbers for future maintenance.

Performance Benefits

The active optical design delivers several tangible advantages over traditional copper or passive fiber solutions:

• Higher Bandwidth: 10 Gbps throughput supports bandwidth‑intensive applications such as virtualization, storage replication, and high‑definition video streaming.
• Reduced Latency: Optical transmission introduces minimal propagation delay, essential for time‑sensitive workloads like financial trading or real‑time analytics.
• Lower Power Footprint: Active cables consume less power than separate transceivers and fiber modules, contributing to overall data center energy efficiency.
• Improved Signal Integrity: Built‑in electronics compensate for minor attenuation, ensuring reliable connectivity even in environments with high electromagnetic interference.
• Simplified Cabling: Eliminates the need for separate power supplies or external transceivers, reducing rack space and cable clutter.

Use Cases

The Cisco 10GBASE SFP+ 2 m Active Optical Cable is suited to a variety of scenarios:

• Data Center Inter‑Rack Links: Connect adjacent switches or server blades within the same rack or neighboring racks.
• Blade Server Connectivity: Link UCS blade chassis to Nexus or Catalyst switches for high‑speed uplinks.
• Campus LAN Backbone: Provide short, high‑bandwidth links between distribution and access layers in enterprise campuses.
• High‑Performance Computing (HPC): Enable low‑latency interconnects between compute nodes or storage arrays.
• Virtualization Platforms: Support hypervisor traffic, virtual machine migration, and shared storage access at 10 Gbps speeds.

Maintenance & Troubleshooting

While the cable is designed for reliability, occasional issues may arise. Follow these steps to diagnose:

1. Check Physical Connections: Ensure connectors are fully seated and free of dust or debris.
2. Verify Power Status: Look for LED indicators on the device port; a solid green light typically indicates an active link.
3. Run Link Diagnostics: Use commands such as “show interface status” or “show cable diagnostics” to assess link health.
4. Inspect for Damage: Examine the cable for visible cuts, kinks, or excessive bending that could affect performance.
5. Replace if Necessary: If diagnostics indicate persistent errors, replace the cable with a new unit from the same batch.

Conclusion

The Cisco 10GBASE SFP+ 2 m Active Optical Cable delivers a compact, high‑speed, low‑latency solution for modern networking infrastructures. Its active design, robust construction, and seamless compatibility with Cisco’s flagship switches and server chassis make it an essential component for enterprises seeking to scale bandwidth while maintaining simplicity in cabling architecture.
