Description
The SFP‑1GE‑SX is a widely used 1 Gigabit Ethernet (1 GbE) SFP transceiver designed for short‑reach fiber connections over multimode fiber (MMF). Complying with the IEEE 802.3z 1000BASE‑SX standard and SFP Multi‑Source Agreement (MSA), this module operates at an 850 nm wavelength and supports transmission distances up to 550 meters on OM2 MMF and greater reach on higher‑grade multimode fiber (e.g., ~1 km on OM3/OM4).
With a duplex LC connector interface and hot‑pluggable small form‑factor design, the SFP‑1GE‑SX is ideal for cost‑effective connectivity within data centers, enterprise networks, campus backbones, and wiring closets. It supports Digital Optical Monitoring (DOM) for real‑time diagnostics of optical parameters such as transmit/receive power, temperature, and voltage — enabling proactive network performance monitoring and troubleshooting.
This transceiver is broadly compatible with network devices that support standard SFP optics, including switches, routers, firewalls, and media converters from many vendors, making it a flexible option for expanding fiber‑based Gigabit Ethernet links.
Key Features:
• 1000BASE‑SX SFP optical transceiver for 1 GbE fiber links
• 850 nm wavelength optimized for multimode fiber (MMF)
• Typical reach up to 550 m on OM2 and longer on OM3/OM4
• Duplex LC connectors for standard fiber patching
• Hot‑pluggable SFP form factor
• Digital Optical Monitoring (DOM) support for diagnostics
