In the era of AI and 5G, the demand for SFP module connectors has transitioned from basic gigabit speeds to massive 400G and 800G throughput. Dorelink stands at the forefront of this industrial shift, providing the physical layer infrastructure that makes global data transmission possible.
High-speed data requires extreme signal integrity. Our EMI-shielded SFP cages and integrated connectors are engineered to minimize crosstalk and electromagnetic interference, ensuring 99.999% uptime in critical server environments.
Leveraging 12 years of industry experience, our manufacturing facility in China integrates automated SMT lines and press-fit technologies that exceed TIA/EIA and MSA standards, delivering unmatched reliability.
Founded in 2016, Dorelink Optical Communications Co., Ltd. is not just a manufacturer; we are a partner in global digital transformation. With a massive 18,500γ‘ facility, we bridge the gap between complex R&D and large-scale commercial availability.
Our expertise spans across the entire lifecycle of optical communication productsβfrom the initial design of PCB mounting shielded RJ45 connectors to the high-complexity engineering of 400G QSFP-DD modules. We serve a diverse global market including North America, Europe, and the Middle East, maintaining over 850 long-term supply chain partnerships.
The transition to "Edge Computing" and "Cloud-Native" architectures is driving a massive surge in fiber-to-the-x (FTTx) and data center interconnects (DCI). SFP (Small Form-factor Pluggable) modules have become the de-facto standard due to their "Hot-Swappable" nature, allowing network admins to upgrade speeds without replacing entire switch systems.
Why source from China? The answer lies in "Integrated Ecosystem Density." At Dorelink, our efficiency isn't just about labor; it's about the proximity of raw material suppliers, high-precision molding shops, and advanced logistics hubs. This allows us to release 85+ new models annuallyβa rate of innovation that keeps our clients ahead of the curve.
As we move toward 800G and 1.6T, thermal management becomes the primary challenge. Our latest Press-fit SMT Heat Sink SFP Cages are designed using advanced thermal simulations to ensure that even the most power-hungry transceivers operate within safe temperature margins.
For operators managing thousands of racks, reliability is non-negotiable. Our QSFP28 100G modules and stacked SFP+ cages (like the 2x4 ports Press Fit models) provide the density required to maximize RU space while maintaining cooling efficiency.
5G Base stations require components that can withstand environmental fluctuations. Dorelink's Industrial Grade Bidi SFP modules and Shielded RJ45 Magjacks are tested for wide temperature ranges and high humidity environments.
In smart factories, EMI from heavy machinery can disrupt data flow. Our EMI-shielded SFP+ cages and magnetic RJ45 connectors offer the robust physical layer protection needed for deterministic Ethernet communication on the factory floor.
To ensure total reliability, every single connector and module undergoes a rigorous 5-stage inspection process before leaving our 18,500γ‘ facility.

Press-fit technology eliminates the need for soldering, which reduces thermal stress on the PCB and allows for easier replacement or repair. It also provides a more consistent electrical connection, which is vital for high-speed signal integrity in 10G and 100G applications.
We maintain an extensive "Compatibility Lab" where our 120+ engineers test every module's EEPROM/firmware against the latest switches from top-tier vendors. We provide customized coding services to ensure seamless plug-and-play operation.
In high-density server environments, electromagnetic interference can cause bit errors. Our cages feature integrated EMI springs and shielded housings that wrap around the module, creating a Faraday cage effect to block outgoing and incoming noise.
Yes. While we have massive production capacity, our R&D team is equipped to handle OEM/ODM requests, including custom PCB mounting layouts and specific heat sink designs for proprietary hardware.
