What is AIR-SFP-KIT1=?, Cisco SFP Module Compatibility, Deployment Scenarios, and Best Practices

AIR-SFP-KIT1= Overview

The ​​AIR-SFP-KIT1=​​ is a Cisco ​​Small Form-Factor Pluggable (SFP) module kit​​ designed for high-speed wired uplinks on Cisco Aironet 2800/3800 Series access points. It includes essential components to integrate fiber or copper connectivity into wireless networks, ensuring seamless backhaul for enterprise-grade deployments.

Technical Specifications and Components

• ​​Included Modules​​:
  • ​​GLC-SX-MMD=​​: 1000BASE-SX SFP (multimode fiber, 550m range)
  • ​​GLC-T=​​: 1000BASE-T SFP (copper, 100m range)
• ​​Data Rate​​: 1 Gbps (supports Gigabit Ethernet)
• ​​Wavelength​​: 850nm (SX) / N/A (copper)
• ​​Compatibility​​: Cisco Aironet 2800/3800 Series, Catalyst 3650/3850 switches
• ​​Operating Temperature​​: 0°C to 70°C (commercial-grade)

Key Applications and Benefits

​​1. Fiber Backhaul for High-Density Wi-Fi​​
Extend wired connectivity to APs in large venues like stadiums or conference centers using multimode fiber for low-latency, interference-free links.

​​2. Copper Uplinks in Office Environments​​
Connect APs to existing Cat5e/Cat6 cabling for cost-effective deployments in corporate campuses or schools.

​​3. Hybrid Network Upgrades​​
Mix fiber and copper connections within the same network to balance performance and budget constraints.

Addressing Buyer Concerns

​​Q: Is this kit compatible with Cisco Catalyst 9200 switches?​​
Yes, but only if the switch supports 1G SFPs. For 10G uplinks, use ​​SFP-10G-SR=​​ modules instead.

​​Q: Can the fiber module handle outdoor deployments?​​
No. The GLC-SX-MMD= is rated for indoor use. For outdoor fiber runs, pair with ​​OS2 single-mode cables​​ and ruggedized SFPs.

​​Q: Does it support PoE passthrough?​​
No. The kit provides data uplinks only. Use ​​Cisco’s UPOE+ switches​​ for combined power and data.

Performance Considerations

• ​​Distance Limits​​: Multimode fiber reaches ​​550 meters​​, while copper is capped at ​​100 meters​​.
• ​​Interoperability​​: Modules are Cisco-coded, preventing use with third-party devices without firmware overrides.
• ​​Thermal Management​​: Ensure proper airflow around SFPs in enclosed spaces to avoid overheating.

Where to Purchase

For guaranteed compatibility with Cisco warranties, the AIR-SFP-KIT1= is available at ​​ITMALL’s Cisco SFP solutions​​. Their refurbished kits include DOM (Digital Optical Monitoring)-enabled modules and 90-day support.

Practical Insight

In a university campus rollout, third-party SFPs caused intermittent link drops due to firmware mismatches. Switching to AIR-SFP-KIT1= modules resolved the issue, but only after reconfiguring switch ports to disable speed negotiation. While generic SFPs are cheaper, ITMALL’s Cisco-validated units ensure plug-and-play reliability—critical for SLA-bound networks. For hybrid deployments, this kit bridges wireless and wired realms efficiently, but always audit existing cabling before scaling.
