Cisco GLC-LH-SMD 1GbE SMF 1310nm SFP Transceiver Module

The Cisco GLC-LH-SMD= is a Small Form-Factor Pluggable transceiver that brings dependable 1 Gigabit Ethernet fiber connectivity to compatible Cisco switches and routers. By inserting this module into an open SFP slot, you immediately gain a link that uses a 1310 nm wavelength on single-mode fiber and conforms to the IEEE 802.3z 1000BASE-LX standard.

Engineered for links up to 10 kilometers, the module is well suited for tasks such as tying together wiring closets across a campus, extending backbone connections between data centers on the same site, or providing a server rack with a dedicated fiber uplink. Because the part follows widely adopted standards, it can run over existing single-mode fiber plant without special conditioning or custom patch cords.

Network administrators appreciate that the module is hot-swappable. You can add, remove, or replace it during normal operation without scheduling downtime, which keeps maintenance windows short and user impact minimal. Compatibility with popular Catalyst, Nexus, and UCS platforms means the same spare can ride in your toolbox and cover many different devices.

The GLC-LH-SMD= also helps when scaling a network. Adding extra uplinks, separating traffic for security, or introducing redundancy becomes straightforward: slide the module in, connect the fiber, and bring the new path online.
