Explore our high-performance transceivers, shielded SFP cages, and advanced RJ45 physical layer hardware engineered for next-generation networks.
In the rapidly accelerating landscape of cloud infrastructures, telecommunications, and industrial automation, physical connectivity remains the ultimate foundation of data rate assurance. Although high-capacity fiber optics capture headlines, copper-based Ethernet and hybrid media integration interfaces (like SFP cages and integrated Magjack connectors) represent over 70% of terminal-to-switch physical connections globally.
Procurement professionals and network architects face dual demands: achieving bandwidth scaling (moving to multi-gigabit speeds like 2.5G, 5G, and 10G over copper) while ensuring extreme physical reliability. The humble RJ45 clip connector—historically vulnerable to physical latch breakage and mechanical fatigue—has undergone a critical structural transformation.

A trusted manufacturer specializing in optical transceivers and high-integrity copper connection components.
Established in 2016, Xelivor Optoelectronics Co., Ltd. is a professional manufacturer of optical transceivers and fiber connectivity solutions, serving global data centers, telecommunications, enterprise networks, and cloud computing industries. Operating from a modern manufacturing facility covering 386 m², we have built an elite reputation for delivering reliable, high-performance communication products worldwide.
How advanced material physics and internal magnetics layout prevent crosstalk and mechanical degradation.
Our RJ45 clip connectors utilize high-flexibility polycarbonate materials featuring "elastic memory." Even when bent to 180 degrees multiple times, the clip resists snapping, maintaining secure terminal locking to eliminate accidental port disconnects in high-vibration environments.
Incorporating multi-point grounding metal tabs, our shielded RJ45 female jacks and SFP cages form an enclosed Faraday cage. This redirects electromagnetic interference straight to the chassis ground, protecting the high-speed differential signal lanes inside the PCB.
Our ethernet connectors integrate discrete magnetic transformers directly within the housing. By performing isolation, common-mode noise filtering, and impedance matching inside the RJ45 footprint, we save layout space and improve overall return loss profiles.
When utilizing multi-port RJ45 connectors (such as 1x4, 2x6, or ganged matrices), adjacent ports present a substantial risk of Alien Crosstalk (ANEXT). At frequencies exceeding 100 MHz (essential for Cat6a 10GBASE-T operations), the electrical paths between pins in neighboring cavities can couple electromagnetically.
To suppress this, Xelivor’s design team integrates internal shielding partitions that run vertically and horizontally between the sub-components. Furthermore, our TE-compatible press-fit cages employ dual-beam contacts and strategic grounding paths to damp resonant frequencies. This ensures that even in compact, high-density layouts (e.g., switches housing 48 ports in a 1U chassis), signal integrity margins remain far below the limit lines defined by TIA-568.2-D standards.
At Xelivor, quality control is not a post-production check—it is a continuous operational discipline. Our quality management system incorporates incoming material inspection, in-process quality control, environmental aging tests, compatibility verification, optical parameter testing, and final product inspection.
A professional quality assurance team of 32 specialized inspectors ensures that every single batch meets international mechanical and electrical standards before dispatch. Utilizing vector network analyzers and high-frequency scope systems, we test insertion loss, return loss, and eye diagrams for optical transceivers, assuring flawless interoperability across OEM switch environments.
Additionally, we maintain long-term, direct cooperation with more than 850 supply chain partners, enabling stable sourcing of high-grade raw plastics, phosphor bronze contacts, and high-frequency optical chips. This allows us to scale manufacturing rapidly while maintaining some of the shortest delivery times in the industry.

How Xelivor’s connectivity systems deploy in critical real-world systems.
Support top-of-rack (ToR) and leaf-spine high-density configurations. Our press-fit, multi-port SFP+ cages and thermal heat-sink enclosures allow optimal airflow and zero-packet-loss connectivity under continuous peak computing loads.
Providing high-precision single-mode and multi-mode transceivers (DDM supported) that maintain stable carrier-grade operations over distances up to 80 kilometers under severe climatic fluctuations.
Robust modular RJ45 designs featuring mechanical locking stability and heavy shield plating to prevent high-voltage EMI interference in automated manufacturing lines and robotics control boxes.
As network architectures migrate from 100G configurations toward 400G and 800G, physical connection modules are adapting to complex physical laws. Xelivor's engineering laboratory is currently refining our thermal design layouts to accommodate higher power envelopes without requiring larger chassis profiles.
In our copper RJ45 roadmap, we are actively developing advanced Cat8-compatible connector systems. These are optimized for high-frequency ranges up to 2000 MHz, utilizing micro-structured internal circuit designs that cancel out NEXT (Near-End Crosstalk) directly at the pin contacts.
Simultaneously, we prioritize eco-responsible materials. In compliance with RoHS and REACH regulations, Xelivor is transitioning toward halogen-free flame-retardant polymers and reducing wastewater production in our gold electroplating facilities. This ensures our global procurement partners receive components that comply fully with localized environmental import requirements.
