Explore our leading Multi-Port & Integrated Magnetic Modular Stacked RJ45 range.
Meeting the demanding bandwidth, thermal efficiency, and PCB spatial constraints of modern IT structures.
Stacked RJ45 setups suffer from crosstalk between upper and lower rows. Our design features advanced multi-point ground grounding fingers (EMI fingers) and interior metal shielding partitions to block crosstalk and EMI. Guaranteed compliance with FCC part 15 Class B and EN 55022 parameters ensures seamless 10GbE speeds.
We support IEEE 800.3af/at/bt specifications. Our stacked magnetic jacks feature balanced transformer coils that manage bias currents up to 1A per port. This thermal margin prevents magnetic core saturation, ensuring clean digital signals and low insertion loss during continuous power transmission.
To maximize board routing efficiency, our stacked connectors feature standard spacing footprints. Precision-formed solder tails allow fast wave soldering or Pin-in-Paste reflow. The layout prevents shorts and provides mechanical durability under repeated patch cord insertions.
Serving telecom networks, system integrators, and OEM customers worldwide with verified hardware capabilities.
Established as a premier provider in high-density ethernet components, Fibronexa Communications Co., Ltd. (operating as a premier partner in fiber optic and physical layer networking solutions) delivers reliable global hardware solutions. Backed by state-of-the-art facilities, we combine precision physical engineering with custom configurations (wavelengths, pin structures, LED mappings, and magnetic configurations) to meet challenging industry expectations.
How we align stacked RJ45 connectors with emerging Multi-Gigabit networks and industrial architectures.
With data requirements shifting to 2.5G, 5G, and 10G Base-T speeds on local nodes, we utilize custom internal transformers. These designs preserve insertion loss margins, keeping return loss below limits at high frequencies (up to 500MHz).
As IoT nodes multiply, PoE requirements are scaling to PoE++ (Type 4, up to 90W/100W). Our roadmap utilizes advanced heat-resistant polymers (LCP) and heavy-gauge contact plating to prevent thermal aging and port carbonization.
For industrial applications, our next-generation housings feature IP-rated sealing and gold plating thicknesses of up to 50 micro-inches, preventing oxidation in high-humidity or corrosive atmospheres.
Leveraging high automation and geographic proximity to material hubs for competitive production advantages.
Our assembly utilizes pick-and-place robots and vision inspection modules. Automating the placement of internal transformers and pins minimizes variability, maintaining reliable impedance controls across production lots.
Located in China's hardware manufacturing hubs, we have direct access to top copper, gold, and polymer suppliers. This localized network ensures stable production schedules even during global material constraints.
Every batch undergoes testing for insulation resistance, dielectric withstand voltage, and mating cycle durability. Combined with our 45+ QC professionals, we ensure zero defects leave our factory floor.
Meeting international regulatory standards for seamless deployment across Europe, the Americas, and Asia.
All materials are lead-free and free from hazardous substances, satisfying RoHS and REACH directives.
Housings are molded with UL 94V-0 flame-retardant thermoplastics, ensuring safety under extreme thermal loads.
We provide FOB, CIF, and DDP shipping terms with tracking to simplify clearance for international buyers.
Our engineers provide rapid design assistance, including PCB footprints, 3D CAD files, and EMI debug support.
