Specifications

Product Description

The Cisco GLC-LH-SMD SFP Transceiver is a high-performance 1000BASE-LX/LH Small Form-Factor Pluggable (SFP) module designed for reliable Gigabit Ethernet connectivity over both single-mode fiber (SMF) and multimode fiber (MMF). Operating at a wavelength of 1310nm, this transceiver delivers stable data transmission up to 10 km on SMF and up to 550 meters on MMF (with mode conditioning patch cable where required).
Engineered for compatibility with a wide range of Cisco switches and routers, the GLC-LH-SMD supports Digital Optical Monitoring (DOM), enabling real-time monitoring of parameters such as temperature, voltage, and optical power levels. Its hot-swappable design allows seamless installation without network downtime, making it ideal for enterprise networks, data centers, campus networks, and service provider environments.
This module ensures secure, high-speed, and long-distance fiber connectivity while maintaining Cisco’s trusted quality and performance standards.
