Premium RJ45 Ethernet + USB combo solutions optimized for high-density networking panels, local terminal systems, and smart factory hardware in the Jabodetabek region.
As the primary financial and industrial engine of Indonesia, Jakarta (alongside the surrounding industrial zones of Bekasi, Tangerang, and Karawang) is undergoing an unprecedented transition toward Industrial IoT (IIoT), smart logistics, and localized cloud data centers. This rapid digitalization has triggered a critical need for rugged, space-saving componentry.
The integration of RJ45 Ethernet ports with high-speed USB connectors in a single stacked configuration has become a standard design approach for local systems integrators. By combining reliable copper-based networking (Gigabit Ethernet) and local hardware peripheral interfaces (USB 2.0 / USB 3.0) into one footprint, local engineers can drastically save PCB real estate, simplify mechanical panel layouts, and reduce manufacturing complexity.
Globally, the electronic interconnect market is moving rapidly toward higher frequencies, enhanced power delivery (Power over Ethernet or PoE+), and extreme port density. The RJ45 with USB stacked combo connector represents a masterclass in hybrid connectivity. Historically, discrete RJ45 modular jacks and USB receptacles required separate PCB routings, causing layout constraints and potential signal degradation due to long trace runs.
Modern telecommunication demands call for integrated magnetic modules (MagJacks) that feature built-in transformers, resistors, and capacitors. This configuration acts as a low-pass filter, preventing high-frequency noise from disrupting the physical layer (PHY) chips. By integrating these magnetics directly within the shielded RJ45 shell, and pairing it with a high-bandwidth USB 3.0 type-A or Type-C module, developers secure a reliable, field-tested plug-and-play solution.
Our comprehensive selection of hybrid connectors finds application in several key growth sectors in Jakarta:
Lumetra Optoelectronics Technologies Co., Ltd. is a professional manufacturer specializing in high-speed optical transceivers and fiber optic communication solutions for datacom, telecom, and cloud infrastructure applications. Founded in 2016, the company has developed into a reliable supplier with strong engineering capabilities and global export experience.
The company operates a production facility covering approximately 8,500㎡, supporting efficient manufacturing and quality-controlled assembly processes. With annual export revenue reaching around USD 18 million, Lumetra has built stable international business channels and accumulated 7 years of export experience, backed by 11 years of overall industry expertise.
Quality assurance is maintained through a combination of automated optical performance testing, environmental stress screening, and manual inspection processes. The quality control team consists of 48 trained inspectors ensuring strict compliance with international standards. We maintain a diversified trade background with a strong presence in OEM and ODM markets, serving primary regions including North America, Europe, Southeast Asia (with a focus on Indonesia and Singapore), and the Middle East.

As transmission bandwidth constraints challenge engineers globally, the hybrid connector product category is evolving on multiple fronts:
Transitioning from traditional dual USB 3.0 Type-A interfaces to USB Type-C architectures that support up to 40 Gbps pathways and power configurations of up to 100W, combining high-speed power transmission and fiber-like network connectivity within the same jack block.
Moving beyond CAT6 (1 Gbps) parameters to handle multi-gigabit speeds (2.5G, 5G, and 10G Base-T). This requires specialized mechanical isolation within the connector housing to prevent interference between high-frequency copper channels.
Integrating dynamic Electrostatic Discharge (ESD) shielding and enhanced magnetic filtering. This ensures maximum board-level protection against lightning surges and common-mode transients, which are common in tropical areas like Jakarta.
By coordinating with over 1,200 supply chain partners, Lumetra ensures that our physical copper connector inventory aligns with high-speed optical transceivers. We offer specialized hardware components that guarantee signal integrity from fiber backhauls down to copper edge points, facilitating seamless translation between optical and electrical configurations.
Backed by our 86 R&D engineers, we specialize in high-level physical layer customization. This includes custom pinout routing, modifying LED light configurations, custom shielding tabs for structural grounding, and integrating custom-wound magnetics tailored for specific transceiver chipsets.
Every batch of RJ45 + USB connectors undergoes strict environmental stress screening, including thermal cycling, humidity chamber testing, and salt-spray testing. This ensures that gold plating on contacts (ranging from gold flash up to 50u") maintains gas-tight connectivity over time.
Standard catalog components are shipped within 2-3 weeks from our manufacturing facility. For custom ODM designs, prototyping requires 4-6 weeks, followed by dynamic production stages. Our 7 years of global export experience ensure optimized Customs clearance through Indonesian gateways.
Yes. Several of our high-speed configurations feature dedicated power paths capable of handling standard PoE (802.3af) and PoE+ (802.3at) currents without causing thermal drift on adjacent USB data channels.
Whether you require standard mechanical replacement parts or custom integrated hybrid connector designs, our global engineering team is ready to assist. Contact us today to receive detailed technical datasheets, CAD models, and custom quotes.
