Product Overview – Cisco GLC-LH-SMD 1000BASE-LX/LH SFP
When network reliability is mission-critical, trust only a genuine Cisco GLC-LH-SMD SFP transceiver. Factory-sealed and engineered to Cisco’s exacting standards, this module eliminates the compatibility issues and signal inconsistencies often found in third-party optics. It is fully hot-swappable, allowing for seamless upgrades and replacements without powering down your network hardware.
The Cisco GLC-LH-SMD is a versatile 1000BASE-LX/LH SFP transceiver designed for Gigabit Ethernet. It offers robust flexibility, supporting transmission over standard single-mode fiber (SMF) up to 10 km and multimode fiber (MMF) up to 550 m (when used with mode-conditioning patch cords). This module features integrated DOM (Digital Optical Monitoring), compliant with industry-standard SFF-8472, enabling real-time diagnostic monitoring of optical power, temperature, and voltage.
