Cisco GLC-LH-SMD 1000BASE-LX/LH SFP Transceiver Module
Product Overview
Elevate your network's performance with the Cisco GLC-LH-SMD, a hot-swappable Gigabit Ethernet SFP transceiver designed for seamless, high-speed data transmission. This module delivers reliable 1Gbps connectivity over both single-mode and multimode fiber, supporting distances up to 10 km on SMF—ideal for enterprise LANs, data centers, and campus networks. Featuring Digital Optical Monitoring (DOM) for real-time diagnostics, it's built for maximum uptime and easy integration with Cisco infrastructure.
Key Features
- Versatile Fiber Support: Operates on standard single-mode fiber (up to 10 km) and multimode fiber (up to 550 m), with mode-conditioning patch cable compatibility for legacy MMF installations.
- Digital Optical Monitoring (DOM): Provides real-time monitoring of optical output/input power, temperature, laser bias current, and supply voltage for proactive network management.
- Hot-Swappable Design: Ensures zero downtime during installation or replacement, maximizing operational efficiency.
- Robust Build: Extended temperature range (-5°C to 85°C) and low power consumption (up to 1W) for demanding environments.
- Standards Compliance: IEEE 802.3z 1000BASE-LX/LH compliant, with dual LC/PC connectors for secure, low-loss connections.
