Cisco Systems Cisco GLC‑LH‑SMD Gigabit SFP Transceiver Module

The Cisco GLC‑LH‑SMD Gigabit SFP Transceiver Module is a versatile, hot‑swappable optical transceiver designed to provide Gigabit Ethernet connectivity over both multimode and single‑mode fiber networks in business, enterprise, and campus environments in Kenya. Supporting extended‑reach fiber transmission up to 10 kilometers, this module enables high‑speed uplinks and inter‑building links between switches, routers, and other network devices. Engineered to Cisco quality standards and compliant with IEEE 802.3z (1000BASE‑LX) specifications, the GLC‑LH‑SMD delivers reliable performance, low latency, and seamless integration with Cisco infrastructure for scalable network deployments.

Product Features

Gigabit Fiber Connectivity

Supports 1000BASE‑LX standard for Gigabit Ethernet over fiber, providing high‑speed data links between networking equipment with reduced signal loss and enhanced transmission distances.

Dual‑Mode Fiber Support

Compatible with both multimode fiber (MMF) using a simplex single‑mode fiber launch and standard single‑mode fiber (SMF), offering flexible deployment options across different fiber infrastructures.

Extended Reach Transmission

Designed for long‑distance fiber links of up to 10 kilometers (over single‑mode fiber), making it ideal for campus networks, inter‑building connectivity, and metropolitan backbone links.

Hot‑Swappable SFP Form Factor

Small Form‑Factor Pluggable (SFP) design allows the module to be inserted or removed from compatible Cisco switches or routers without powering down the system, minimizing network disruption during maintenance or upgrades.

Broad Cisco Compatibility

Works with a wide range of Cisco switches and routers that support 1G SFP interfaces, enabling flexible integration into existing network architectures and expansion projects.

Auto‑Negotiation and Duplex Support

Supports auto‑negotiation and full‑duplex operation for seamless link establishment and optimized throughput performance across fiber connections.
