Innovating for the next generation of multi-gigabit and high-wattage PoE networks.

PoE++ and High Wattage Integrity

As Power over Ethernet standards scale to IEEE 802.3bt (up to 90W-100W), contact resistance and thermal management inside the duplex RJ45 become critical. Our future designs employ optimized copper alloys to eliminate current-induced heating and contact pitting under load.

10GBASE-T Migration

We are advancing signal path optimization within multi-port and duplex configurations to achieve crosstalk suppression at high frequencies up to 500 MHz, ensuring seamless Cat6A 10Gbps transmission over 100 meters without packet loss.

Co-Packaged Optics & Copper Hybrid

By leveraging our strong background in photonic transceivers and active optical components, we are engineering hybrid modular panels that consolidate optical duplex LC and copper duplex RJ45 networks into a single, high-density line card design.

Macro Industry Solutions

Adapting connectivity interfaces to meet the needs of demanding application environments.

Cloud Data Center Interconnects

For high-density top-of-rack (ToR) switch architectures, our duplex RJ45 connectors feature space-saving mechanical outlines and integrated low-crosstalk magnetics, offering cost-effective and reliable copper uplink configurations alongside 100G/400G optical fiber links.

Industrial Automation & Smart Factories

Electromagnetic noise in industrial environments can corrupt Ethernet frames. Our duplex shielded RJ45 female sockets include heavy-duty brass shielding and grounding tabs to maintain signal integrity in environments utilizing variable frequency drives (VFDs) and high-voltage robotics.

Technical Q&A (FAQ)

Common questions regarding integration, custom manufacturing, and design modifications.

What are the key advantages of integrated magnetics in duplex RJ45 connectors?
Integrated magnetics (or MagJacks) consolidate the isolation transformer, common-mode chokes, resistors, and capacitors inside the RJ45 housing. This saves PCB board space, minimizes electromagnetic interference (EMI) paths, suppresses common-mode noise, and simplifies overall motherboard layout design.
Can FiberQ customize the pinout configurations for OEM customers?
Yes. Our internal R&D engineering group regularly adapts internal PCB trace routes, transformer winding turns ratios, physical pin lengths, and housing footprint geometries to match specific requirements from physical layer (PHY) chip manufacturer evaluation boards.
How do your connectors maintain high quality across long production runs?
We use a multi-step quality control system. Our automated equipment checks coplanarity, solderability, and pin placement precision. Every batch is evaluated using industrial network analyzers to confirm insertion loss, return loss, and near-end crosstalk (NEXT) meet regulatory thresholds. Our team of 62 certified inspectors oversees these testing processes.
Are these connectors suitable for Power over Ethernet (PoE) installations?
Absolutely. We offer customized multi-port and duplex RJ45 jacks with dedicated wire winding designs suited for PoE, PoE+ (IEEE 802.3at), and PoE++ (IEEE 802.3bt) configurations, supporting safe power routing alongside gigabit data streams.
What are the lead times for custom tooling and prototype shipping?
For modifications to existing tooling (such as varying LED combinations or shield configurations), prototypes are typically finalized within 2 to 3 weeks. Custom complex structural designs involving dedicated mold modification generally require 4 to 6 weeks for test validation.
