The compatibility is backed by extensive testing and a reputation for minimizing compatibility headaches in mixed-vendor environments.
• Premium performance over multimode fiber: Built for 1000BASE-SX operations, the transceivers use 850 nm wavelength optics optimized for multimode fiber (MMF). They support full-duplex, 1 Gbps Ethernet transmission, providing robust data rates for small-to-mid-sized networks, server access, and uplinks between distribution switches. Whether you’re upgrading an aging MMF backbone or expanding a data center spine, these modules maintain solid throughput with low error rates.
• Great value with bulk convenience: The 10-pack configuration delivers significant cost savings and simplified logistics for IT departments managing multiple links or sites. Stock up once and deploy across several devices without worrying about spare parts or last-minute procurement delays. The bulk format is especially advantageous for network refreshes, lab environments, and layered redundancy strategies.
• Quality you can rely on—with support and warranty: StarTech’s SFPs are engineered for consistent performance in real-world deployments and come with a solid warranty and support options. In addition to the product’s compatibility assurances, you gain access to StarTech’s technical resources and service commitments, helping you resolve issues quickly and keep your network running smoothly.
• Easy installation and broad management compatibility: Designed for plug-and-play deployment, these SFP modules require no configuration. They transparently negotiate link speed with compatible switches, NICs, and routers, letting you focus on network design rather than gadgetry. The modules work well with a wide range of network management tools and monitoring platforms, enabling operators to track link status, utilization, and error rates with minimal overhead.

Technical Details of StarTech.com Cisco GLC-SX-MM Compatible SFP Module 10 Pack

• Standard: 1000BASE-SX compliant, providing 1 Gigabit Ethernet over multimode fiber (MMF).
• Fiber Type: Multimode Fiber (MMF)—ideal for short-to-medium distance deployments within data centers or campus environments. Performance varies with fiber grade (OM1/OM2/OM3) and connector quality.
• Wavelength: 850 nm, optimized for high-bandwidth data transmission over MMF networks.
• Connector: LC duplex connector (standard for SX optics) to ensure compatibility with common fiber cabling and patch panels.
• Distance: Supports typical MMF link lengths for 1000BASE-SX, with greater distances achieved on higher-grade MMF (e.g., OM2/OM3/OM4) and appropriate fiber infrastructure. Actual reach depends on fiber type and installation environment.
• Data Rate: 1.0 Gbps full-duplex Ethernet throughput, suitable for core-to-edge links, access connections, and uplinks in enterprise networks.
• Compatibility: Cisco GLC-SX-MM compatible transceiver from StarTech, designed to align with Cisco-equivalent specifications while delivering StarTech-grade reliability.
• Package: 10-pack to support multi-site deployments, lab testing, or rapid scale-out initiatives.
• Operating Environment: Commercial-grade components designed for standard data-center/server-room conditions. Always verify that your equipment and cabling meet manufacturer recommendations for best results.
• Warranty: Includes StarTech’s standard warranty and access to technical support resources for setup, compatibility checks, and troubleshooting.

How to install StarTech.com Cisco GLC-SX-MM Compatible SFP Module 10 Pack

• Power down the device (switch, router, or media converter) before inserting or removing an SFP module to prevent damage and ensure a safe installation.
• Locate an available SFP slot and carefully align the module with the slot. Insert straight until it seats securely with a gentle click. Avoid forcing the module into place.
• Connect your multimode fiber optic cable to the LC duplex connector on the SFP module. Ensure the fiber is clean, free of dust, and terminated with matching LC connectors.
• Power on the device and monitor the link status via the device’s management interface. The link LED should indicate an active connection if the fiber, interfaces, and network gear are properly configured.
• Verify 1 Gbps operation, check for error-free traffic, and confirm the link’s stability with your network monitoring tools. If you encounter issues, reseat the module, verify fiber orientation, or test with a known-good SFP and fiber to isolate the fault.

Frequently asked questions

• Q: What does “1000BASE-SX” mean? A: 1000BASE-SX denotes a Gigabit Ethernet standard for short-range fiber optic links that use multimode fiber and an 850 nm wavelength. It is optimized for distance ranges typical of MMF installations within buildings or campuses.
• Q: Is this StarTech SFP compatible with Cisco devices? A: Yes. The product is marketed as Cisco GLC-SX-MM compatible, meaning it is designed to work with Cisco switches and routers that support GLC-SX-MM-style SFP modules. Always ensure compatibility with your specific firmware version and hardware model.
• Q: Do I need any configuration to use these SFPs? A: For most installations, plug-and-play operation is sufficient. The SFPs will auto-negotiate speed and duplex with compatible devices. If your network requires specific VLANs, QoS, or link aggregation settings, configure those on your network devices as needed.
• Q: What kind of fiber should I use? A: Multimode fiber (MMF) such as 50/125 µm or 62.5/125 µm is typical for 1000BASE-SX. The effective distance depends on the fiber grade (OM1/OM2/OM3/OM4) and connector quality. Use clean, properly terminated MMF cables to maximize performance.
• Q: What is the advantage of buying a 10-pack? A: A 10-pack reduces per-unit costs, simplifies stocking for IT teams managing multiple sites, and accelerates deployment across racks, closets, or lab environments. It’s an efficient choice for scaling network upgrades or performing rapid replacement.
