GLC-SX-MMD-RF

1000BASE-SX SFP xcver module, MMF, 850nm, DOM REMANUFACTURED

GLC-SX-MMD-RF is a professionally remanufactured Cisco 1000BASE-SX SFP transceiver module, designed to provide Gigabit Ethernet connectivity over multimode fiber in enterprise LAN and data center environments. This compact, hot-swappable module supports link lengths of up to 550 meters over 50/125 µm multimode fiber and up to 220 meters over 62.5/125 µm multimode fiber using an 850nm VCSEL laser.

This remanufactured SFP transceiver meets Cisco original equipment specifications and has been thoroughly inspected and tested to ensure reliable performance. Validation includes optical transmit and receive power levels, digital diagnostics monitoring (DDM) functionality, and compatibility with Cisco IOS-based switches and routers.

Key Features:
• 1000BASE-SX Gigabit Ethernet over multimode fiber (MMF) at 850nm wavelength
• Supports up to 550m reach on 50/125 µm OM2 multimode fiber
• Hot-swappable SFP form factor for flexible, non-disruptive installation
• Digital Diagnostics Monitoring (DDM) for real-time optical performance visibility
• Compatible with Cisco Catalyst, Nexus, and ASR platforms supporting SFP slots
• LC duplex connector interface with a data rate of 1.25 Gbps
