Cisco 1000BASE-LX/LH SFP Transceiver Module
Brand: Cisco · SKU: GLC-LH-SM · MPN: GLC-LH-SM · Category: Networking
The GLC-LH-SM is a high-performance, reliable SFP module designed for seamless integration in enterprise networking solutions. It is a 1000BASE-LX/LH SFP for both Multimode (MMF) and Single-Mode Fibers (SMF). It operates on standard single-mode fiber-optic link spans of up to 10 km and up to 550 m on any multimode fibers (62.5um or 50um core size). The module is compatible with the IEEE 802.3z 1000BASE-LX standard for Gigabit Ethernet networks. It features a wavelength of 1310nm, a maximum data transfer rate of 1.25 Gbps, and is hot-swappable. It typically uses a Dual LC connector and has a low power consumption of less than 1 Watt. Digital Diagnostics Monitoring (DDM) is generally not supported for the genuine Cisco part, although compatible versions may offer it.
