Micro Mini USB-Powered Gigabit Ethernet to SFP Fiber Media Converter
Overview
The LNK-M3011-SFP is an ultra-compact Gigabit media converter that seamlessly connects
copper and fiber networks. Featuring USB power input, wide-range DC support, and SFP
flexibility, it delivers portable, energy-efficient, and long-distance connectivity up to 120 km.
Ideal for fiber-to-laptop and space-constrained networking environments.
Features
Smallest form factor – lightweight, only 46g, fits behind any PC
Flexible SFP slot – supports 100/1000M, multi-/single-mode fiber
Dual power options – USB-powered (plug-and-play) or 5–15VDC input
Energy saving – auto shutdown when host device powers off
High performance – supports 9K jumbo frames, low BER <10⁻⁹
Rugged design – aluminum casing for durability and heat dissipation
Extended fiber reach – up to 120 km with the right SFP module
