One Cable, Two Solutions: Industrial PoE+ Splitter Delivers Gigabit Data and 5VDC Power, Redefining Edge Device Power Architecture 802.3af/at Input, Regulated 5VDC/2A Output, -40~80°C Operation. Provides Zero-Modification Access for Traditional Non-PoE Devices. In Industrial IoT deployments, a vast number of legacy devices (such as serial servers, specific sensors, display units, etc.) still rely on traditional DC power supplies like 5V, 12V, or 24V. They cannot directly utilize the increasingly prevalent PoE networks for power, forcing the deployment of separate power cabling on-site, which adds complexity and cost. To solve this "last-meter" challenge of integrating power and data, E-link China officially introduces the Industrial Gigabit PoE+ Splitter. This product intelligently separates a standard PoE network signal into a gigabit data stream and a stable 5VDC power output. It enables seamless integration of existing non-PoE devices into modern, unified industrial Ethernet architectures without any modification, serving as a critical bridge for the network upgrade of traditional equipment. Core Functionality: Decoupling and Enabling Intelligent Separation, Clean Outputs: Single Input Port (RJ-45 PoE IN): Receives the combined data and power signal from a standard 802.3af/at PoE switch or injector. Dual Independent Outputs: Data Output Port (RJ-45 DATA OUT): Provides a pure Gigabit Ethernet data signal, ensuring lossless 10/100/1000BASE-T transmission. Power Output Terminal (2-pin Terminal Block): Delivers a stable, isolated 5VDC supply, with a maximum output current of 2A (10W), meeting the needs of most low-power, non-standard devices. Industrial-Grade Reliability Design: Comprehensive Protection: Built-in output short-circuit, overload, and reverse-connection protection safeguards both the upstream PoE equipment and the downstream powered device. Wide Environmental Tolerance: Operates in a -40°C to 80°C temperature range.

In order to deepen team collaboration, stimulate innovative energy, and draw inspiration from natural wonders, E-link team successfully conducted an immersive three-day, two-night themed team-building retreat in Yingde, renowned as the "Foremost Peak Forest and Water Country of Southern China," from Dem 20 to 22. Centered around the theme "Carved by Nature, Forged as One," the activity aimed to allow team members to comprehend the essence of cooperation through the marvels of nature and forge stronger team bonds through exploration and relaxation. Day 1: Warm Springs, Melting Barriers, a Gentle Start The retreat began gently on the first day at Yingde's natural hot springs. Team members relaxed their bodies and minds in the mineral-rich warm waters, engaged in heartfelt conversations, and broke down barriers amidst the rising steam, building trust. The hot spring session served not only as physical and mental relaxation but also as an emotional and intellectual "warm-up," establishing a warm and open team tone for the challenges ahead. Day 2: Exploring the Karst, Listening to Each Other in the Echoes of the Caves The event commenced amidst Yingde's magnificent karst landscape. The team first ventured deep into an underground cave system, navigating through a fantastical forest of stalactites and subterranean rivers. This "journey to the center of the earth" was not only a visual feast of natural wonders but also a unique exercise in team collaboration. Within the cavern halls that held both profound serenity and majestic beauty, team members supported and encouraged one another, deepening their默契 in the quiet atmosphere. Just as the theme metaphorically suggests, team dynamics, like these wonders shaped over millennia by persistent droplets, require the "carving" of time and shared effort to reveal their brilliance. Day 3: Ascending the Peak Forest, United Toward the Horizon The last stop was Fenglin Xiaozhen. The thousand-mu flower sea within the scenic area changes with the seasons, and the types of flowers keep changing, presenting a riot of colors. The entertainment programs are rich and diverse, including Peak Forest Flight, hot air balloon, Peak Forest Sightseeing Train, Scream Fountain, Lotus Lake Cruise, Jurassic Exploration Park, and Pet Zoo, among others. Structured in the sequence of "Hot Springs — Caves — Peak Forest," this retreat built an experiential ladder of "Relaxation — Exploration — Transcendence." Employee feedback indicated that the journey naturally transitioned from physical and mental relaxation to spiritual cohesion, ultimately升华 to shared vision, forming a complete and profound cycle of team empowerment.The company consistently values the symbiotic growth of teams in natural settings. This journey to Yingde was not merely a traverse through geographical space, but also a vivid portrayal of the team's evolution from "fusion in warmth" to "ascending together with consolidated strength." In the future, we will continue to design rhythmic and profound team experiences that foster the synchronous growth of the organization and its individuals.
