Gigabit Ethernet Media Converter 1000Base-SX/LX 120km SFP Slot

Gigabit Ethernet Media Converter 1000Base-SX/LX 120km SFP Slot

Product Overview

The LNK-3011 Series Gigabit Ethernet Media Converter enables seamless copper-to-fiber conversion, supporting 10/100/1000Mbps auto-negotiation for high-speed network extension. Compliant with IEEE 802.3/u/z/ab standards, this converter efficiently bridges twisted-pair Ethernet (10/100/1000Base-T) and fiber optic (1000Base-SX/LX) networks, extending transmission distances from 100m over copper to 120km over fiber.
