The Cisco GLC-LH-SM SFP transceiver is designed for Cisco Gigabit Ethernet SFP ports and supports 1000BASE-LX/LH connections. It works with LC fiber ports and is commonly used on compatible Cisco switches and routers that accept hot-swappable SFP modules.

Installation is simple: power can stay on, then insert the hot-swappable GLC-LH-SM module into a compatible SFP slot until it clicks. Connect your LC fiber cable, then verify link status on the device. No special tools are typically required.

This Cisco 1000BASE-LX/LH SFP uses a 1310nm duplex LC optical interface and is built for reliable 1Gbps fiber networking. It supports up to 10 km over single-mode fiber and up to 550 m on multimode fiber, meeting IEEE 802.3z and SFP MSA standards.
