Cisco GLC-SX-MMD 1000BASE-SX SFP Transceiver Module, MMF (850nm), DOM

Description

Cisco GLC-SX-MMD – 1000BASE-SX SFP Transceiver Module

The Cisco GLC-SX-MMD is a 1 Gbps multimode fiber (MMF) SFP transceiver module designed for short-range fiber optic connections. It operates at 850nm wavelength and supports Digital Optical Monitoring (DOM) for real-time diagnostics, making it ideal for enterprise networks, data centers, and campus environments.

Key Specifications:

• Form Factor: SFP (Small Form-Factor Pluggable)
• Interface: LC Duplex Connector
• Data Rate: 1.25 Gbps (Gigabit Ethernet & Fiber Channel)
• Wavelength: 850 nm (Multimode Fiber – MMF)
• Transmission Distance:
  • Up to 550m (1,804 feet) on OM2 fiber
  • Up to 220m (722 feet) on OM1 fiber
• Power Consumption: 1W (low power usage)
• DOM Support: Yes (Digital Optical Monitoring for real-time diagnostics)
• Operating Temperature: 0°C to 70°C (Standard version)
• Hot-Swappable: Yes, can be installed or removed without rebooting the switch or router

Key Features:

✔ Short-Range Fiber Connectivity: Ideal for intra-building links
✔ High-Speed 1Gbps Data Transmission: Reliable and efficient
✔ Digital Optical Monitoring (DOM): Provides real-time performance monitoring
✔ Low Power Consumption: Energy-efficient design (1W)
✔ Hot-Swappable: No need to reboot the switch or router during installation

Compatible Cisco Devices:

✅ Cisco Catalyst Switches (e.g., 2960, 3560, 3750, 9200, 9300, 9500, etc.)
✅ Cisco Nexus Data Center Switches
✅ Cisco ISR & ASR Routers
✅ Cisco ME Series Metro Ethernet Switches
