GLC-SX-MMD Use Case
High-Density Data Center Uplinks with GLC-SX-MMD-1000BASE-SX SFP
In a hyperscale data center, network architects deploy the GLC-SX-MMD-1000BASE-SX SFP transceiver in top-of-rack and spine switches to deliver 1 Gbps links over multimode fiber (MMF) at 850 nm up to 550 m. Integrated Digital Optical Monitoring (DOM) provides real-time metrics—optical power, temperature and link health—enabling proactive fault detection and streamlined maintenance. The result is a cost-effective, scalable uplink solution that maximizes port density, minimizes downtime and supports mission-critical workloads with end-to-end visibility.
Enterprise Campus Building-to-Building Fiber Backbone
For a multi-building corporate campus, IT teams install the GLC-SX-MMD-1000BASE-SX SFP module in aggregation switches to interconnect remote floors and buildings over existing multimode fiber infrastructure at 850 nm. With DOM functionality, facility managers monitor link parameters and quickly isolate degradation or fault events before they impact business operations. This deployment ensures reliable 1 Gbps connectivity across distances up to 550 m, reduces capital expenditure on new cabling and guarantees high-performance access to cloud services and unified communications.
Industrial Automation Control Network Fiber Link
In a manufacturing plant’s automation network, engineers use the GLC-SX-MMD-1000BASE-SX SFP transceiver to connect programmable logic controllers (PLCs) and human-machine interfaces (HMIs) over multimode fiber at 850 nm. The transceiver’s DOM capability delivers continuous optical diagnostics, helping maintenance teams detect signal loss, temperature shifts or connector faults before production stops. This approach provides deterministic 1 Gbps performance, enhances operational resilience and supports strict safety and uptime requirements in industrial Ethernet environments.
