About the GLC-SX-MMD 1G SFP LC Multimode Transceiver (850nm)
The GLC-SX-MMD 1G SFP LC Multimode Transceiver (850nm) is a compact SFP transceiver delivering 1.25 Gbps throughput over multimode fiber at 850 nm wavelength, ideal for short-reach enterprise campus and data center deployments. Built by Cisco, the GLC-SX-MMD implements the IEEE 802.3z 1000BASE-SX standard and supports maximum reach of 220 meters over OM1 62.5/125 µm fiber or 550 meters over OM2 50/125 µm fiber, making it suitable for intra-building and intra-campus connectivity. The transceiver features an LC Duplex connector, full duplex operation, and employs a VCSEL (Vertical-Cavity Surface-Emitting Laser) for reliable, efficient signal transmission.
Network engineers and IT infrastructure teams benefit from this module's hot-swappable design, enabling field replacement without system downtime. The transceiver includes Digital Optical Monitoring (DOM) for real-time performance visibility and health diagnostics. Cisco's GLC-SX-MMD operates across the industrial temperature range of 0°C to 70°C and carries CE, FCC, and RoHS regulatory compliance certifications, ensuring deployment flexibility in diverse enterprise environments. For organizations standardizing on Cisco optics or requiring proven interoperability with existing SFP-based infrastructure, this module delivers predictable, field-tested performance.
