1000BASE-SX SFP Transceiver Module (1Gbps, 850nm, MMF, 550m, LC, DOM)
Brand: Generic/Compatible · SKU: GLC-SX-MMD-COMP · MPN: GLC-SX-MMD · Category: Networking
The 1000BASE-SX SFP (Small Form-factor Pluggable) transceiver is a compact, hot-swappable optical module designed for high-performance Gigabit Ethernet communication. This module operates at a nominal wavelength of 850nm and is optimized for short-range data transmission over multi-mode fiber (MMF). It supports data rates up to 1.25 Gbps and can reach distances up to 550 meters (1804 feet) using OM2/OM3/OM4 cabling. Equipped with a duplex LC connector, the module is fully compliant with the SFP Multi-Source Agreement (MSA) and IEEE 802.3z standards. The 'D' version includes Digital Optical Monitoring (DOM/DDM) capabilities, allowing for real-time monitoring of operating parameters such as transceiver temperature, laser bias current, transmitted optical power, and received optical power. It is ideal for enterprise LANs, data center interconnects, and storage area networks (SANs).
