Cisco GLC-SX-MM-RGD 1000BASE-SX SFP Multi-Mode Rugged transceiver

The Cisco GLC-SX-MM-RGD is a ruggedized SFP (Small Form-Factor Pluggable) transceiver designed for reliable 1 Gbps data transmission over multi-mode fiber. It is ideal for industrial and harsh environments where standard SFPs may not withstand extreme temperatures or vibration. This module complies with the 1000BASE-SX standard and supports distances up to 550 m over 50/125 µm multi-mode fiber.

Advantages

Ruggedized design ensures operation in extended temperature ranges (0 to 70 °C) and resistance to shock and vibration. Hot-swappable for easy installation and maintenance. Digital Optical Monitoring (DOM) provides real-time diagnostics for proactive network management. Low power consumption (<1 W) reduces energy costs.

Suitable for

• Industrial Ethernet networks
• Outdoor or harsh environment deployments
• Enterprise and data center fiber optic connections
• Video surveillance and remote monitoring
