FiddlLink
FiddlLink Optical Technology Co., Ltd. is a leading global manufacturer specializing in high-performance optical transceivers and fiber optic communication solutions. Since our inception in 2016, we have focused on bridging the gap between cutting-edge R&D and large-scale industrial deployment. Based in a state-of-the-art facility, we support the world's most demanding data centers, telecommunications networks, and enterprise infrastructures.
With over 12 years of core industry experience and 8 years of dedicated export operations, we have established a reputation for reliability and technical excellence. Our annual export revenue of USD 18 million is a testament to our global footprint across North America, Europe, and Asia.
The global Ethernet interface connector market is undergoing a paradigm shift driven by the explosion of Artificial Intelligence (AI), the Internet of Things (IoT), and 5G infrastructure. Modern enterprises no longer view connectors as simple passive components; they are critical nodes that dictate the latency, throughput, and reliability of the entire digital ecosystem. From the shift towards 400G and 800G optical modules to the integration of PoE+ (Power over Ethernet) in industrial automation, the demand for high-density, thermally efficient, and EMI-shielded solutions is at an all-time high.
As a premier OEM/ODM factory, FiddlLink addresses these needs by providing "Information Gain"—proprietary insights into signal integrity and thermal management that allow our partners to outperform their competitors. We analyze macro-industrial trends to ensure our technical roadmap aligns with the next generation of IEEE and MSA standards, providing our clients with future-proof hardware.
Our roadmap focuses on increasing port density without compromising signal integrity. This includes the development of stacked RJ45/USB combos and low-profile SFP+ cages designed for 1U rack efficiency.
Transitioning from 10G/25G to 100G/400G QSFP-DD modules. Our R&D team specializes in DDM (Digital Diagnostic Monitoring) and CWDM/DWDM technologies for long-reach transmission up to 80km.
From firmware configuration and compatibility programming to custom hardware PCB design and branding. We provide tailored solutions that integrate seamlessly with Cisco, Juniper, and Arista environments.
Integrated magnetic modules that support Power over Ethernet (PoE/PoE+) for smart building and industrial IoT applications, ensuring stable power and data delivery over a single interface.
All FiddlLink products are manufactured in compliance with international standards, including RoHS, CE, FCC, and UL. We ensure our Ethernet connectors meet the strict environmental and safety regulations of European and North American markets.
With 8 years of export experience, we have mastered global logistics. We offer door-to-door delivery and real-time tracking, ensuring that our partners in the Middle East, SE Asia, and South America receive their orders on schedule.
Our relationship doesn't end at delivery. We provide 24/7 technical support for firmware updates, compatibility issues, and network troubleshooting, acting as an extension of your engineering team.
For standard models, lead times are generally 2-3 weeks. For custom ODM designs involving new PCB layouts or proprietary housing, the timeline varies from 6-10 weeks including prototyping and validation.
Our optical transceivers undergo rigorous compatibility programming. We maintain a library of EEPROM codes for Cisco, Juniper, HP, and other major vendors to ensure "plug-and-play" functionality.
Yes, our vertical and right-angle RJ45 modular jacks are designed for high-vibration environments and support 10/100/1000 Base-T standards, frequently used in PLC and industrial automation.
Every module undergoes optical performance testing (TX/RX power), environmental reliability testing (temperature cycling), and bit error rate (BER) testing to ensure long-term stability.
