FiddlLink
Portugal has emerged as one of Europe’s most dynamic hubs for technology and industrial innovation. From the tech startups in Lisbon to the advanced manufacturing clusters in Porto and Aveiro, the demand for robust, space-saving, and high-speed data connectivity solutions has reached an all-time high. The RJ45 Connector with USB integrated module represents a critical evolution in hardware design, addressing the convergence of networking and peripheral power/data transfer.
The Portuguese industrial landscape requires components that meet stringent European standards (CE, RoHS) while offering the flexibility for local customization. Our factory supports Portuguese sectors including:
Modern PCB design in Portugal's tech sector is moving toward extreme miniaturization. Traditional separate RJ45 and USB ports consume significant board "real estate." Our Stacked RJ45 with USB 3.0/3.1 solutions reduce footprint by up to 40%. The technical roadmap includes:
With 10G Base-T and USB 3.1 Gen 2 becoming the standard, EMI shielding is paramount. Our connectors utilize advanced internal grounding and high-quality shielding cages to prevent crosstalk between the high-speed data lanes and the Ethernet signals.
Integrated modules can generate localized heat. We use high-temperature resistant LCP (Liquid Crystal Polymer) materials for our housings, ensuring stability even in the harsh environments of Portuguese industrial factories.
While many "factories" offer standard connectors, FiddlLink focuses on the E-E-A-T principles of reliability. We specify 50u" gold plating for all contact points to prevent oxidation—a critical factor for Portugal’s coastal industrial zones (like Sines or Setúbal) where humidity and salinity can compromise signal quality.
FiddlLink Optical Technology Co., Ltd. leverages the massive efficiency of the Chinese electronics ecosystem to serve Portugal with unmatched lead times. Our 380sqm facility is a hub of precision engineering, ensuring that every RJ45+USB combo meets international performance benchmarks.






With an annual revenue of USD 18 million and a robust R&D team of 126 experts, we don't just supply; we innovate. Our OEM/ODM services allow Portuguese engineers to request specific firmware configurations or customized shielding for niche applications in aerospace or defense.
The primary advantages are space efficiency and simplified PCB assembly. By integrating these two essential ports into a single footprint, developers in Portugal can design smaller enclosures for IoT gateways and industrial controllers, while reducing the number of components that need to be picked and placed during manufacturing.
All our products are manufactured under a comprehensive quality management system with 42 QC personnel. We ensure full compliance with RoHS and REACH standards, providing the necessary documentation for smooth customs clearance at major Portuguese ports like Lisbon or Leixões.
Yes, many of our integrated modules are designed to support PoE and PoE+ standards (up to 30W) while maintaining isolated USB power delivery. This dual-power capability is ideal for remote monitoring stations and smart building sensors frequently used in Portuguese infrastructure projects.
Typically, standard modifications take 2-3 weeks, while full custom ODM designs (from design to prototype) take 6-8 weeks. Our efficient logistics network ensures rapid delivery to Portugal via air or sea freight.
