High-reliability modules engineered for seamless connectivity
Whitepaper: Leading the SFP Manufacturing Standards in China
In the era of hyper-connectivity, the demand for high-speed, low-latency data transmission has never been more critical. Dorelink Optical Communications Co., Ltd., established in 2016, stands at the forefront of this digital revolution. As a premier China SFP Transceiver Module Factory, we combine 12 years of profound industry expertise with advanced manufacturing capabilities to deliver 800G-ready optical solutions. Our mission is to bridge the gap between complex network requirements and reliable, scalable fiber hardware.
Deploying Optical Excellence across Diverse Vertical Markets
Optimizing leaf-spine architectures with high-density QSFP28 and SFP28 modules. Our solutions support 100G/200G/400G throughput with minimal power consumption, ensuring sustainable hyperscale growth.
Enabling the next generation of mobile connectivity. Our SFP modules provide the backbone for 5G fronthaul and backhaul, supporting CPRI/eCPRI protocols and wide-range industrial temperatures (-40°C to +85°C).
From AI-driven surveillance to municipal automation, our industrial-grade transceivers ensure reliable data flow across vast urban networks, even in electromagnetically noisy environments.
Cost-effective, high-compatibility modules for Cisco, Juniper, and Huawei ecosystems. We provide the "plug-and-play" reliability needed for corporate LANs and campus-wide fiber backbones.
Ruggedized SFP solutions for oil & gas, mining, and manufacturing. Featuring enhanced EMI shielding and vibration resistance to maintain signal integrity in harsh conditions.
Ultra-low jitter transceivers designed for 4K/8K video transmission, ensuring zero-frame loss for real-time media streaming and cloud-based post-production.
Engineering Reliability through Precision and Expertise
Our commitment to reliability is backed by a 45-person professional QC team. We don't just "test"—we validate every photon. Our protocols include:
With 120 dedicated engineers, Dorelink is not just a manufacturer; we are an innovation hub. In the past year alone, we released 85 innovative models, focusing on:
Navigating International Standards with Compliance & localized Support
Full compliance with CE, FCC, and RoHS. We provide local warehousing options and 24/7 technical support for our Western tier-1 distributors.
Specialized solutions for high-humidity and high-temperature environments. Our ruggedized SFPs are the choice for regional telecom giants.
From customized firmware for legacy systems to specialized labeling and packaging, we offer a tailored experience for every region.
The next generation of optical interconnects
