Cisco GLC-SX-MMD 1000BASE-SX SFP Transceiver Module Overview

The Cisco GLC-SX-MMD 1000BASE-SX SFP Transceiver Module is a Gigabit Ethernet fiber-optic transceiver designed to provide high-speed connectivity between compatible Cisco switches, routers, and other network equipment. It uses the 1000BASE-SX standard and is designed specifically for multimode fiber (MMF) networks using an 850nm optical wavelength.

The module uses a standard SFP form factor, allowing it to be installed into compatible SFP slots on Cisco networking equipment. This modular design provides network administrators with flexibility when configuring fiber-based uplinks and interconnecting network devices.

The GLC-SX-MMD uses a duplex LC connector, providing a standard interface for compatible multimode fiber-optic patch cords. It is well suited to short- and medium-distance fiber links commonly found within office buildings, server rooms, data centers, campus networks, and other structured network environments.

A key feature of the GLC-SX-MMD is Digital Optical Monitoring (DOM). DOM provides monitoring information about the transceiver's operating conditions, helping network administrators monitor parameters such as optical performance and module operating status when supported by the host equipment.

The 850nm wavelength is optimized for multimode fiber deployments. This makes the GLC-SX-MMD a practical choice where existing MMF infrastructure needs to be connected to compatible Gigabit Ethernet equipment.

The module can be used for switch-to-switch connections, network uplinks, server connectivity, campus networks, and data-center infrastructure where 1 Gigabit fiber connectivity is required. Its compact SFP design also makes it convenient for expanding or modifying existing network infrastructure without replacing the host networking equipment.

The Cisco GLC-SX-MMD typically falls within the KSh 7,500–10,000 price range in Kenya, depending on supplier, condition, authenticity, warranty, and availability.
