The Cisco GLC-SX-MMD is a small form-factor pluggable (SFP) transceiver module. It is designed to provide Gigabit Ethernet connectivity over multimode fiber optic cables. The "SX" in the model name stands for short wavelength, indicating that it operates at a wavelength of 850nm. The "MMD" stands for Multimode/Media/Multi-Mode Digital Diagnostics, which means it supports digital diagnostics monitoring capabilities for enhanced network management. This transceiver module is commonly used in Cisco networking equipment to enable high-speed data transmission over short distances.
