Description

The Cisco 1000BASE-LX/LH SFP Transceiver Module (GLC-LH-SMD) delivers high-performance Gigabit Ethernet connectivity for Cisco switches, routers, servers, and NICs. Supporting both multi-mode (MMF) and single-mode fiber (SMF), it enables link lengths of up to 10 km over LC duplex connections.

Designed for reliability and flexibility, this hot-pluggable SFP supports Digital Optical Monitoring (DOM) for advanced diagnostics and is compliant with IEEE 802.3z standards. With low power consumption and wide temperature tolerance, it is ideal for data centers, telecom networks, and enterprise deployments in both indoor and outdoor environments.
