FiddlLink
The global demand for wired network connectors is shifting toward 800G and beyond. As AI and Machine Learning workloads increase, the need for low-latency interconnects like SFP28, QSFP28, and next-gen RJ45 with integrated magnetics has peaked. We are seeing a 40% increase in demand for "Press-Fit" technology to reduce signal loss in high-frequency applications.
Modern global enterprises are moving away from proprietary lock-ins toward Multi-Source Agreement (MSA) compliant components. Procurement teams now prioritize vendor reliability, EMI shielding performance, and backward compatibility. Our TE and Cisco compatible series provide the perfect balance of cost-efficiency and Tier-1 performance.
Beyond basic connectivity, our components address thermal management and electromagnetic interference (EMI). All products meet RoHS, REACH, and UL standards, ensuring that your network infrastructure remains stable in harsh industrial or high-density server environments.
FiddlLink Optical Technology Co., Ltd. stands as a beacon of innovation in the optical communication landscape. Founded in 2016, we have leveraged over a decade of industry expertise to provide solutions that power the world's most critical data centers.
Our 380-square-meter facility is not just a factory; it is a high-tech hub where 42 quality control experts oversee every micron of production. Last year alone, we introduced 186 new products to the market, catering to the rapid evolution of 5G and Edge Computing.








Utilizing our 2x4 and 2x6 stacked SFP+ cages and RJ45 connectors to maximize rack space while maintaining 10G/25G/100G line speeds. Our integrated magnetics reduce PCB footprint by 35%.
Designed for vibration resistance and extreme temperatures, our vertical RJ45 and PoE+ modules support smart factory connectivity and reliable sensor data transmission.
Our R&D roadmap focuses on OSFP and QSFP-DD form factors. By investing in Single-Lambda 100G technology, we help clients transition to hyper-scale architectures with minimal infrastructure replacement.
With an export footprint spanning North America, Europe, and Southeast Asia, FiddlLink provides more than just hardware. We provide peace of mind through localized technical support and regulatory compliance.
Every transceiver and connector undergoes Interferometer and Transreflector testing. Our MTF Transmittance meters ensure that optical paths are flawless, meeting the strict requirements of telecom operators worldwide.
From custom EEPROM coding for Cisco, Juniper, or Arista compatibility to unique mechanical housing designs, our engineering team works as an extension of your own R&D department.
