High-speed copper Ethernet connectors, optical transceivers, and SFP+ housing cages optimized for low insertion loss and high EMI suppression.
Established in 2016, Transolix is an internationally recognized optical transceiver and high-reliability copper connectivity module manufacturer. We serve critical needs in fiber optic and high-speed copper communications for next-generation data centers, telecommunications carriers, industrial automation networks, and Tier-1 enterprise applications.
Leveraging over 11 years of deep industry expertise and 6 years of focused B2B cross-border export experience, we bridge the gap between high-speed copper interconnects (such as integrated magnetic RJ45 modules) and optical communications. Our engineered products solve signal loss, mechanical wear, and electromagnetic interference (EMI) at the physical layer, ensuring multi-vendor hardware environments operate seamlessly.
Our corporate facility acts as our centralized design, validation, and advanced testing laboratory. By combining this centralized oversight with a certified upstream network of over 860 raw material, component, and silicon suppliers, we achieve an agile, resilient supply chain capable of scaling to high-volume production without sacrificing component pedigree.
Navigating the transitions from Gigabit Ethernet to 10G Base-T and next-generation optoelectronic hybrid solutions.
Modern networks require robust Electromagnetic Interference (EMI) mitigation. Our RJ45 Integrated Connector Modules (ICMs) feature advanced tab-down shielding and integrated magnetic transformers. These components suppress common-mode noise, manage Near-End Crosstalk (NEXT), and protect signals in dense, high-frequency environments.
To meet bandwidth demands up to 500MHz and beyond, our connectors support Cat6A and Cat8 parameters. By optimizing copper contact pins with gold plating (up to 50μ"), we reduce insertion loss and maintain stable impedance. This performance supports short-reach 10G Base-T links in modern data centers and enterprise networks.
As optical and copper technologies converge, our R&D roadmap focuses on transceiver miniaturization. We design hybrid interfaces that convert high-speed optical backplanes to RJ45 copper connections. These modules allow operators to upgrade to fiber networks while utilizing existing copper cabling infrastructure.
Tailored hardware and transmission components optimized for specific operating environments and networking tiers.
Data centers demand low-latency, high-density patch fields and switch interconnects. Our SFP+ copper modules, multi-port RJ45 connectors, and low-profile magnetic jacks are engineered to reduce board space. Our passive line cages minimize airflow obstruction and optimize heat dissipation, helping control the thermal profiles of core switch racks.
Industrial environments subject hardware to mechanical stress, wide temperature fluctuations, and electromagnetic interference. Our MOXA-compatible industrial copper transceivers operate reliably in harsh conditions. With built-in ESD protection and specialized PCB layouts, these RJ45 connectivity modules ensure stable links on factory floors and within energy grids.
Combining an active R&D hub, advanced testing protocols, and a network of 860+ certified upstream partners for flexible manufacturing.
To maintain consistent product quality and fast turnaround times, Transolix operates an integrated production ecosystem. Our 320m² state-of-the-art facility serves as our primary engineering, firmware customization, and quality auditing hub. High-volume manufacturing is scaled through our partnership with 860+ certified upstream vendors, who supply verified silicon, high-frequency magnetic cores, and gold-plated pins according to our specifications.
Every shipment undergoes structured testing overseen by our 42 quality control professionals. By using automated optical testing, eye diagram analysis, and environmental chamber aging, we ensure that every module meets return loss, crosstalk, and electrical isolation standards before dispatch.
Supporting large-scale deployments through multi-protocol compatibility, customizable firmware, and international certification compliance.
OEM/ODM customers require modules that are compatible with multi-vendor networks. We offer tailored firmware EEPROM programming to ensure that our SFP and RJ45 copper transceivers work seamlessly with equipment from major brands like Cisco, Moxa, Juniper, and Huawei. This minimizes the risk of port lockouts and configuration issues.
Our engineers can customize module wavelengths, transmission distances, and form factors. We also offer mechanical adjustments, including low-profile tab-down pins, vertical top-entry configurations, and integrated LEDs. This flexibility helps hardware teams optimize port density on custom PCB boards.
We maintain compliance with key international standards to ensure smooth importing and deployment. All Transolix products are manufactured in accordance with ISO 9001 quality management guidelines. Our manufacturing processes also meet RoHS, REACH, UL, CE, and FCC requirements, ensuring environmental safety and electrical reliability.
Answers to technical and logistics questions commonly asked by hardware designers, network engineers, and purchasing managers.
Discrete solutions place the RJ45 jack and the magnetic transformer at separate locations on the PCB. In contrast, Integrated Connector Modules (ICMs) consolidate the Ethernet transformer, common-mode chokes, resistor networks, and the RJ45 housing into a single shielded unit. This integrated design reduces PCB trace lengths, improves signal integrity, and helps mitigate electromagnetic interference (EMI). It also saves board space and simplifies production assembly.
We use EEPROM microcontroller programming to match the vendor MSA protocols of major networking brands. During testing, each module is verified with the target switch or host adapter. This ensures that the host firmware recognizes the transceiver's DOM/DDM values and port data, preventing diagnostic alarms or link rejections in multi-vendor environments.
To support industrial operations (such as -40°C to +85°C ranges), we use higher-rated components, robust isolation transformers, and heavy gold-plated contact pins (up to 50μ"). In addition, our manufacturing teams perform high-temperature aging, thermal shock testing, and 100% final testing. These steps help prevent corrosion and signal degradation in demanding environments.
We offer extensive customization for our connectivity modules, including:
• Custom form factors and housing dimensions (such as low-profile, tab-down, vertical top-entry, or multi-port ganged configurations).
• Integrated LEDs (various colors) and custom-fit SFP/SFP+ metal cages.
• Electrical parameters tailored to specific PHY transceivers, including customized turn ratios, internal magnetics, and ESD protection levels.
• Optical wavelength adjustments, variable distances (from short-reach to 80km+), and custom EEPROM firmware codes.
We audit and qualify all upstream vendors to ensure component quality. Core components, including optical sub-assemblies, driver ICs, and high-frequency ferrite cores, are sourced only from certified suppliers. Our 42 quality control professionals perform incoming inspection on raw materials before they enter our production lines, maintaining traceability and quality across our supply chain.
