The Cisco GLC-LH-SMD is a 1 Gigabit Ethernet SFP (Small Form-factor Pluggable) transceiver module designed for long-range, single-mode fiber (SMF) connectivity. Operating at a 1310nm wavelength, this module provides reliable Gigabit Ethernet performance over distances of up to 10 kilometers (6.2 miles), making it an excellent choice for enterprise, campus, and data center networks where extended reach is required.

This module utilizes an LC duplex connector for fiber optic connections, ensuring efficient and stable data transmission. It features a Fabry-Perot (FP) laser as the transmitter and a PIN photodiode as the receiver, offering excellent signal quality. With a power consumption of less than 1W, the GLC-LH-SMD is energy-efficient, contributing to lower operational costs.

The Cisco GLC-LH-SMD is hot-swappable, meaning it can be installed or replaced without needing to power down the device, ensuring minimal network downtime. It operates within a temperature range of 0°C to 70°C, making it suitable for a variety of commercial and industrial environments.

Compliant with IEEE 802.3z for Gigabit Ethernet and SFF-8472 for SFP modules, it provides robust performance and compatibility with a wide range of Cisco switches and routers that support SFP ports. This transceiver module is ideal for businesses that need reliable, long-distance fiber connectivity for their networks.

The Cisco GLC-LH-SMD offers a high-quality, cost-effective solution for single-mode fiber Gigabit Ethernet deployments, ensuring fast, reliable, and scalable network infrastructure.
