Dorelink
Explore our tier-one lineup of copper transceivers, low-profile modular jacks, and integrated magnetics designed for next-generation network performance.
In the modern telecom and enterprise ethernet landscape, the physical layer remains the bedrock of network reliability. Cable manufacturers and exporters require component suppliers that provide more than just standardized commodities. Dorelink Optical Communications Co., Ltd. delivers high-engineering-grade, customized OEM RJ45 connectors featuring integrated magnetics (Magjacks), advanced EMI shielding, and ruggedized housing profiles.
Our products bridge the gap between high-speed copper networking and reliable signal transmission. By implementing 50μ" gold-plated contact surfaces, phosphor bronze contact interfaces, and robust high-temperature LCP housings, Dorelink RJ45 modular jacks withstand severe environmental conditions while maintaining structural and electrical integrity over a minimum of 750 mating cycles.
Established in 2016, Dorelink has grown to become a global leader in high-performance copper interconnects and optical modules.
Over 12 years of core industry experience and 7 years of direct international export experience. We act as a reliable partner for global optical & copper communication distributors and system integrators.
We released over 85 innovative transceiver and connector models last year, backed by proprietary hardware design, automated micro-welding, and comprehensive signal integrity analysis.
Operating with a dedicated 45-person QC inspection team enforcing multi-stage IQC, IPQC, FQC, and reliability aging tests to achieve 99.98% factory yield rates.
Engineering the physical layer for next-generation multi-gigabit copper links.
While long-haul data center backplanes rely on optical fibers, copper remains highly dominant in LAN, enterprise access nodes, and PoE-powered equipment due to its cost-efficiency, power delivery capability, and robustness. The challenge is scaling traditional RJ45 footprints to manage gigabit data rates without experiencing unacceptable loss.
Modern designs demand compatibility with Cat6A (up to 500MHz) and Cat8 (up to 2000MHz) parameters. Meeting these requirements requires modifying pin designs, adjusting internal lead pathways, and refining shielding materials to minimize Near-End Crosstalk (NEXT) and Far-End Crosstalk (FEXT).
| Standard | Frequency | Shielding Requirement | Max Distance |
|---|---|---|---|
| Cat 5e | 100 MHz | UTP (Unshielded) | 100 Meters |
| Cat 6A | 500 MHz | STP/F-UTP (Shielded) | 100 Meters |
| Cat 8 | 2000 MHz | S-FTP (Double Shielded) | 30 Meters |
*Note: As frequencies scale to 2GHz, shielding integrity determines whether the system passes channel testing. Low-cost stamped shells cannot deliver the EMI performance needed for Cat8 standards.
Custom RJ45 modular jacks and SFP systems tailored to critical end-use environments.
Top-of-Rack (ToR) and End-of-Row (EoR) switches require ultra-dense layout options. Our low-profile vertical SMT RJ45 ports and multi-port stacked cages are designed to maximize port density while retaining reliable mechanical retention.
Manufacturing floors generate high levels of electromagnetic interference and mechanical vibrations. Our gold-plated shielded RJ45 jacks with integrated LEDs and robust grounding tabs ensure continuous physical contact and continuous signal pathways.
Base stations, FTTH gateways, and DSLAM systems rely on our specialized LAN magnetic transformers to provide voltage isolation and prevent signal degradation, ensuring reliable performance in harsh outdoor deployments.
High-precision machinery controls liquid crystal polymer (LCP) flow, ensuring tight dimensional tolerances for gold pin channels.
Continuous brass alloy processing and automatic electro-plating lines guarantee a consistent 50 micro-inch gold layer across all mating points.
Located in the heart of China's optical and copper manufacturing hubs, Dorelink's 18,500㎡ facility is optimized for lean production and rapid order fulfillment. We combine vertical production structures with localized logistics networks to minimize lead times for international clients.
Our factory relies on advanced automation. By replacing manual connector wiring and plastic housing assembly with high-speed automated insert molding systems, we have achieved a monthly production capacity exceeding 5 million connector ports. This ensures that large cable exporters can count on consistent lead times even during seasonal demand spikes.
This manufacturing model, combined with our network of over 850 long-term supply chain partners, allows us to secure stable raw materials and control costs, protecting our clients from volatility in copper and plastic resin pricing.
How our 45-person Quality Control team guarantees performance and standards compliance.
Every batch of raw brass, phosphorus bronze contacts, LCP resins, and metal shield housing undergoes testing. We use X-Ray Fluorescence (XRF) scanners to verify gold plating thickness and ensure compliance with RoHS and REACH standards.
Our production lines feature Automated Optical Inspection (AOI) systems that verify pin alignment, contact spacing, and coplanarity in real-time. Any deviation triggers immediate feedback loops to maintain zero-defect standards.
Samples from each batch are subjected to high-temperature thermal cycling tests (-40°C to +85°C), relative humidity testing, salt spray testing for corrosion resistance, and mechanical vibration tests to ensure long-term durability.
Key parameters for cable manufacturers and network hardware engineers when sourcing custom components.
Standardized components often fall short of meeting specific spatial constraints, PCB layouts, or performance targets. Dorelink provides extensive customization options, allowing you to configure every detail of the modular jack.
Choose from nickel-plated copper alloys or stainless-steel outer shells. Multiple grounding tabs can be placed on the top, sides, or bottom of the shield to match your enclosure's ground plane.
We customize the internal transformer ratios, common-mode choke placements, and shunt capacitor values to ensure your PHY transceiver chips achieve optimal insertion and return loss performance.
We offer contact plating thicknesses ranging from gold flash to 50 micro-inches (50u"). Select the right plating based on your application, whether you are targeting low-cost consumer gear or high-durability industrial designs.
