Dorelink
Dorelink
As a leading CE certified RJ45 terminator manufacturer, we recognize that high-speed data transmission is highly susceptible to EMI. Our terminators ensure that unused ports do not act as antennas, preventing noise ingress and maintaining compliance with strict European EMC directives.
Ethernet circuits operate on a 100-ohm characteristic impedance. Open ports cause signal reflections (standing waves) which degrade the Signal-to-Noise Ratio (SNR). Our precision-engineered terminators provide the exact resistive load required to eliminate these reflections.
While standard terminators suffice for Cat5e, 10GBASE-T and Cat6a systems demand tighter tolerances. We utilize advanced crosstalk-cancellation designs to support the massive bandwidth requirements of modern AI data centers and 5G edge computing nodes.

Industry Experience
Established in 2016, Dorelink Optical Communications Co., Ltd. has emerged as a powerhouse in the research, development, and supply of high-performance optical and copper connectivity products. Our 12-year industry pedigree allows us to navigate the complexities of global supply chains while delivering uncompromising quality.
Our commitment to the E-E-A-T principle (Experience, Expertise, Authoritativeness, and Trustworthiness) is reflected in our robust QC team of 45 professionals and our record of 85 innovative product releases in the last year alone.
For hyperscale data centers, signal integrity is paramount. Our RJ45 terminators are used to seal unused management ports in Top-of-Rack (ToR) switches, reducing packet loss and ensuring 99.999% uptime.
In factory automation, vibration and electrical noise are constant threats. Our ruggedized, CE-certified terminators offer localized support for harsh environments, ensuring PLCs and industrial gateways remain stable.
With over 850 long-term partners, we provide seamless procurement for distributors in North America, Europe, and Southeast Asia. Our "Just-in-Time" delivery model mitigates project delays for system integrators.
Our products undergo rigorous testing including Optical power testing, Wavelength testing, and Temperature cycling. For our European clients, the CE mark is not just a label; it represents our adherence to the Safety, Health, and Environmental protection requirements of the EU.
We provide comprehensive OEM/ODM services, including custom firmware and labeling, to help local brands scale their infrastructure offerings.
Dorelink implements a comprehensive quality management system covering:
Our 45-person QC team utilizes automated performance verification to ensure every RJ45 terminator and optical module meets international standards before export.
An RJ45 terminator is used to "close" an unused network port. It prevents electrical signals from reflecting back into the circuit (impedance matching) and blocks EMI, which is critical for maintaining high speeds in Cat6a and Cat7 environments.
CE Certification ensures the product complies with EU safety and electromagnetic interference standards. For global suppliers, it is a mandatory requirement for selling into the European Economic Area, guaranteeing that the terminator won't disrupt other electronic equipment.
Yes. As an OEM manufacturer, Dorelink can customize the internal resistor values (typically 100 Ohms for standard Ethernet) and housing materials (shielded vs. unshielded) to meet specific engineering requirements.
We leverage our 18,500㎡ facility and 850+ supply chain partners to provide stable lead times. We offer tiered pricing for data center operators and system integrators with an annual export capacity of USD 18 million.
