Explore our leading catalog of RJ45 magnetic connectors, copper transceivers, and optical transceiver modules engineered for zero packet loss.
Navigating the evolution of high-performance copper connectivity in the era of 10G/40G architectures and advanced PoE deployment.
Transitioning beyond legacy Cat5e. We optimize the internal magnetic configurations of our RJ45 connectors to support frequencies up to 2000 MHz (Cat8), minimizing Insertion Loss and maximizing Return Loss thresholds.
Supporting IEEE 802.3bt Type 4 applications up to 90W-100W of power delivery. Our modular jacks utilize thick 50μ" gold-plated contacts to prevent spark-erosion damage during live disconnects under full loads.
Integrating advanced metal grounding tabs and internal shielding mechanisms to mitigate alien crosstalk (ANEXT) and electromagnetic interference (EMI) within ultra-dense high-frequency rack mount applications.
The industry is experiencing a dynamic convergence between optical fiber backbones and localized high-power copper endpoints. While fiber dominates the structural core of hyperscale networks, copper remains critical for horizontal connectivity, power delivery, and smart-device endpoints. As a leading manufacturer of both high-end SFP transceivers and robust RJ45 magnetic sockets, Xelivor is uniquely positioned to deliver reliable systems covering both copper and fiber infrastructures.
| Ethernet Standard | Maximum Data Rate | Frequency Spec | Connector Type Interface | Primary Industrial Use-Case |
|---|---|---|---|---|
| Cat 5e (Legacy) | 1 Gbps | 100 MHz | RJ45 (8P8C) Unshielded/Shielded | Standard office LAN routing |
| Cat 6 / Cat 6A | 10 Gbps | 250 - 500 MHz | RJ45 Shielded with Grounding Tabs | Enterprise Servers, Edge Computing Nodes |
| Cat 8.1 / Cat 8.2 | 25 Gbps to 40 Gbps | 2000 MHz | Fully Shielded RJ45 / Modified Interfaces | Data Center Switch-to-Server Interconnections |
Tailored connectivity components engineered to withstand challenging environmental conditions, high duty cycles, and strict certification audits.
Industrial settings demand resilience against thermal fluctuations, vibration, and dust ingress. Our custom-fabricated RJ45 connectors feature robust housing materials, optioned with integrated LEDs and advanced PCB magnetics, ensuring steady communication links inside smart manufacturing lines, programmable logic controllers (PLCs), and edge computer cabinets.
For high-density enterprise routing and data centers, signal density and heat dispersion are paramount. We offer a hybrid physical layer catalog. By matching our RJ45 interfaces with top-tier active optical transceivers (including 25G SFP28 and 100G QSFP28 modules), we assist engineering teams in mapping out hybrid topologies that balance cost, throughput, and link longevity.
Ensuring operational reliability through rigorous E-E-A-T manufacturing framework and CE-certified testing processes.
Driving proprietary structural designs, firmware customizations, and signal integrity simulations (HFSS) to out-perform standard signal-to-noise guidelines.
Implementing multi-stage testing including incoming raw material checks, in-process assembly monitoring, automated optical inspection (AOI), and final optical/electrical validation.
Guaranteeing continuous access to high-grade phosphor bronze contacts, engineering-grade resins, and copper alloys even during global raw material shortages.
Xelivor ensures every RJ45 connector, magnetic modular jack, and SFP module conforms strictly to localized regulations. Our products bear the CE Mark, validating compliance with all European health, safety, and environmental protection legislations. Furthermore, we satisfy RoHS and REACH directives, ensuring that harmful substances are eliminated from the production cycle, protecting local ecosystems and complying with strict enterprise purchasing mandates in Western markets.
To secure a reliable physical layer link, we conduct rigorous testing profiles:
• Mechanical Reliability Testing: Durability testing ensuring a minimum of 750 mating/un-mating cycles without degradation in connection performance.
• Environmental Testing: Thermal shock resistance testing ranging from -40°C to +85°C to secure outdoor and telecom cabinet operations.
• Signal Integrity Verification: Time Domain Reflectometry (TDR) and Network Analyzer checks ensuring insertion loss, return loss, and NEXT levels meet or exceed international TIA-568-C.2 standards.
Combining modern automation, high engineering capabilities, and deep logistic integration from our Chinese manufacturing hub.
Established in 2016, Xelivor operates a modernized manufacturing facility that leverages high-precision Surface Mount Technology (SMT) and automated terminal insertion lines. Automation ensures that every solder joint on our multi-port magnetic RJ45 connectors exhibits consistent thickness, eliminating human errors and signal drift. This capability allowed us to successfully roll out more than 85 new SKU designs in the past calendar year alone.
Understanding that every network vendor has proprietary structural and routing designs, we offer complete customization services. This includes customized PCB pin layouts, custom-colored housings, integrated LED options, custom-flashed firmware parameters for transceivers, and private label/packaging solutions. Over $12 Million in annual export revenues demonstrates our capability to manage both high-volume distribution runs and tailored, batch-based system integrator requests.
Our 68-member research and development division quickly drafts customized 3D models and test prototypes, cutting lead times down from several months to a few weeks.
Situated in an active electronic manufacturing region, we enjoy direct access to deep-water shipping lanes, high-speed rail freight, and express air corridors, allowing for safe and rapid deliveries across North America, Europe, Southeast Asia, and South America.
A technical guide for procurement directors, network architects, and system integrators to mitigate hardware degradation and reduce overall network maintenance costs.
When source-evaluating physical layers components, price per unit is only a small fraction of the formula. True evaluation must account for Total Cost of Ownership (TCO). Inferior RJ45 sockets or uncertified copper transceivers lead to high packet loss, signal retries, equipment overheating, and unexpected downtime. A single hour of network failure in a data center environment can cost tens of thousands of dollars.
To safeguard your deployment, our engineering team recommends verifying three crucial elements during procurement validation:
1. Contact Plating Integrity: Insist on 50-micro-inch gold-plated copper alloy pins to prevent corrosion and sustain contact resistance below 20 mΩ over decades of operational service.
2. Shielding Effectiveness: Ensure the connector's metal cage is constructed using premium nickel-plated copper alloys with multiple grounding points to divert stray currents and suppress electromagnetic noise.
3. Standard Integration Compliance: Demand verifiable CE certificates and electrical performance test reports from third-party certification authorities before bulk ordering.
Addressing the critical questions asked by optical and copper communication engineers and hardware procurement teams.
Integrated RJ45 magnetic connectors combine the physical connector jack with the electrical isolation transformers and filter elements into a single shielded housing. This saves valuable PCB board space, reduces electromagnetic noise due to shorter signal pathways, improves EMI shielding, and simplifies circuit routing for network engineers, ultimately decreasing overall assembly failure rates.
CE Certification serves as proof that the connector complies with critical safety and environmental directives in Europe, such as the Low Voltage Directive and the Electromagnetic Compatibility (EMC) standards. Without verifiable CE certifications, enterprise networks risk compliance audits, customs rejection, and potential fire safety hazards during heavy PoE++ deployments.
Our pins utilize a high-tensile phosphor bronze base core, which is plated with a nickel underplate layer followed by an outer layer of 50 micro-inch gold plating. This configuration forms a solid barrier against oxidation and mechanical wear, preventing fretting corrosion even in high-humidity or industrial factory environments.
Yes. Active copper transceivers (such as our 2.5G SFP Copper RJ45 module) convert SFP ports into standard RJ45 ports, enabling network administrators to connect standard copper Ethernet cables directly into optical switch ports. This approach maximizes port efficiency and simplifies hybrid copper-fiber scaling.
