About the Cisco 1000BASE-SX Cisco 1G SFP SX transceiver

Operating at 850 nm wavelength over multimode fiber, the Cisco 1000BASE-SX transceiver delivers Gigabit connectivity across distances up to 550 m on 50/125 µm MMF (OM2) and 275 m on 62.5/125 µm MMF (OM1) fiber types. This SFP (Small Form-factor Pluggable) module conforms to the IEEE 802.3z 1000BASE-SX standard and represents a proven, cost-effective solution for enterprise campus and data center interconnect deployments where multimode fiber infrastructure already exists.

Network engineers and IT procurement teams standardizing on Cisco infrastructure choose the 1000BASE-SX for its reliability, hot-swappable design, and broad ecosystem support. The module operates across a commercial temperature range of 0°C to 70°C, consumes typically ≤1.0 W of power, and features VCSEL (Vertical-Cavity Surface-Emitting Laser) transmission technology paired with LC Duplex connectors. Built-in Digital Optical Monitoring (DOM) support—platform-dependent—enables real-time link diagnostics via the I²C management interface, while MSA (Multi-Source Agreement) compliance ensures interoperability across Cisco platforms. The part number 1000BASE-SX carries Cisco IOS integrity check compliance and supports firmware authentication, critical for security-conscious organizations.

Whether upgrading existing multimode infrastructure or deploying new Gigabit links within campus or data center environments, the Cisco 1000BASE-SX offers proven performance and straightforward integration into Cisco-based networks. Organizations require a reliable transceiver that balances cost, reach, and operational simplicity—and this module delivers across all three dimensions.
