Dorelink
Dorelink
Established in 2016, Dorelink Optical Communications Co., Ltd. has rapidly ascended as a premier manufacturer in the optical communication sector. With 12 years of industry depth, we bridge the gap between complex signal demands and robust hardware execution.
Our 18,500㎡ modern facility in China serves as the nerve center for high-precision assembly. We utilize automated testing to ensure every RJ45, SFP cage, and transceiver meets rigorous international standards.
With an annual export revenue of USD 18 million and 7 years of specialized export experience, we support critical infrastructure across North America, Europe, and Southeast Asia.
In the era of AI-driven data centers and 5G ubiquity, Ethernet cable connectors have evolved from simple passive components to complex sub-systems. Today’s high-performance connectors must address Signal Integrity (SI), Electromagnetic Interference (EMI), and Thermal Management simultaneously.
Modern PCB designs demand "Ganged" or "Stacked" configurations (like our 1x8 or 2x4 SFP cages). This increases port density without sacrificing EMI shielding effectiveness, crucial for 100G and 400G switches.
As IoT devices require more power, RJ45 connectors with integrated magnetics (MagJack) must now support PoE+ and PoE++ (up to 90W) while maintaining 10GBASE-T data rates without saturation.
Beyond the office, connectors now face extreme temperatures and vibration. Our SMT and Press-fit solutions ensure mechanical stability in industrial automation and automotive Ethernet applications.
Standard RJ45 & SFP modules focused on basic connectivity and cost-efficiency.
Introduction of QSFP28, advanced EMI shielding, and thermal heat sinks for high-heat environments.
Silicon Photonics integration, OSFP/QSFP-DD form factors, and AI-optimized low-latency interconnects.
Ethernet connectivity is not a "one size fits all" industry. We tailor our manufacturing to meet specific regional and sector-based requirements.
High-humidity environments in SE Asia require connectors with specialized gold-plating thickness (up to 50u") and anti-corrosion housings for outdoor 5G small cell deployments.
Focus on low-latency 100G PLR4 modules and high-density SFP cage assemblies that support liquid cooling and efficient airflow designs.
Adherence to strict DIN standards and PROFINET compatibility. Our magnetic RJ45 jacks with high isolation voltages are essential for German and Italian manufacturing floors.
Dorelink leverages the unparalleled ecosystem of China’s electronics manufacturing clusters. This allows for vertical integration—from raw metal stamping for SFP cages to precision optical sub-assembly (OSA).
Our commitment to reliability is backed by a 45-person professional QC team. We don't just ship products; we ship "Confidence."
Rigorous screening of raw PCB, optical chips, and metal alloys before production begins.
Real-time monitoring of automated assembly lines and signal integrity during manufacture.
100% testing of optical power, wavelength accuracy, and bit-error rate (BER).
Temperature cycling (ranging from -40°C to +85°C) and long-term burn-in tests to ensure zero-defect field performance.
A: Magnetic RJ45 connectors (MagJacks) integrate transformers and chokes into the housing. This provides critical EMI suppression, signal conditioning, and electrical isolation (up to 1500Vrms), which protects sensitive PHY chips and improves overall network stability.
A: Yes. Our R&D team specialized in firmware optimization and compatibility testing. We can encode transceivers to be 100% compatible with Cisco, Juniper, Arista, HP, and other major networking brands.
A: Our cages utilize high-grade copper alloys with nickel or tin plating and feature advanced "360-degree" spring finger gaskets to eliminate gap leakage, ensuring compliance with FCC and CE electromagnetic emission standards.
A: Absolutely. All our manufacturing processes and materials are fully compliant with RoHS, REACH, and UL certification requirements, ensuring safe and sustainable integration into global markets.
