Juniper EX‑SFP‑1GE‑SX Compatible 1000BASE‑SX Gigabit Ethernet SFP Transceiver Module

Description

The EX‑SFP‑1GE‑SX is a 1000BASE‑SX small form‑factor pluggable (SFP) optical transceiver module designed for short‑range multimode fiber (MMF) Gigabit Ethernet connectivity. Compliant with the IEEE 802.3z 1000BASE‑SX standard, it operates at an 850 nm wavelength and supports data transmission at up to 1 Gbps over multimode fiber cables. Typical reach is up to 550 m on OM2 MMF using a duplex LC connector, making it ideal for campus backbone links, enterprise LAN uplinks, and fiber extensions within buildings or across adjacent facilities.

This hot‑pluggable SFP module conforms to SFP MSA and SFF‑8472 standards, ensuring broad compatibility with Juniper routing and switching platforms as well as other MSA‑compliant equipment. Many variants include Digital Diagnostic Monitoring (DDM/DOM) support for real‑time operational metrics (such as optical power and temperature), which aids in network performance visibility and troubleshooting.

Key Features:
• 1000BASE‑SX SFP module for Gigabit Ethernet over multimode fiber (MMF)
• Up to ~550 m reach at 850 nm wavelength on MMF
• Duplex LC connector for fiber interfaces
• Hot‑swappable SFP form factor for flexible deployment
• Support for Digital Diagnostic Monitoring (DDM/DOM) options
