The Cisco GLC-SX-MMD 1000BASE-SX SFP is a Small Form-Factor Pluggable (SFP) transceiver module designed for 1 Gigabit Ethernet uplink connectivity. It is an improved version of the previous GLC-SX-MM, featuring Digital Optical Monitoring (DOM) functionality and an extended temperature range. This module supports hot-swappable installation, allowing devices to be added or removed without powering them down. DOM capability provides real-time diagnostics for monitoring signal strength, temperature, and transceiver supply voltage. The transceiver can tolerate an extended temperature range of 23°F to 185°F. It is compatible with various Cisco switches and routers, including ASA5500 Series Appliances, ASR routers, Catalyst switches, and more. The module operates at an 850nm wavelength and is intended for multimode fiber (MMF) only, supporting distances up to 550 meters over 50 µm multimode fiber, up to 220 meters over 62.5 µm FDDI-grade multimode fibers, and up to 1km over laser-optimized 50
