Importance and Key Characteristics The core value of the PoE Splitter lies in enabling non-PoE devices to adapt to the PoE power supply system, eliminating the cost of separately laying power cables and enhancing the flexibility of device deployment. Taking the E-link LNK-INS301 series as an example, the Industrial PoE Splitter has the following core characteristics: supporting 10/100/1000Mbps Gigabit transmission, with a transmission distance of up to 100 meters; operating in a wide temperature range of -40~80°C, with an IP40 metal casing suitable for harsh environments; equipped with short-circuit, surge, and ESD protection to ensure circuit safety; featuring a PWR/POE LED diagnostic light, supporting DIN rail and wall-mounted dual installation methods, and being plug-and-play without configuration. Working Principle The PoE Splitter needs to be used in conjunction with PoE switches, injectors, and other power supply end (PSE) devices. The E-link LNK-INS301 series receives the mixed signals from the PSE device through its RJ45 PoE input port and completes the separation of data and power within its internal circuit: the data signal is output through an independent RJ45 data port while maintaining the Gigabit transmission rate; the power signal is converted to 19VDC and supplied to the non-PoE device through 2-pin connector terminals, enabling synchronous transmission of data and power over a 100-meter distance in Cat5 and above cables. Installation Tips This type of device is designed for easy installation: first, use Cat5 and above UTP cables for wiring to ensure the stability of transmission and power supply; second, connect the PoE input port to the PSE device, the data port to the network port of the non-PoE device, and the power terminal to the power supply end of the device; third, the device is pre-installed with a DIN rail bracket and a wall-mounted bracket as standard, allowing for flexible selection based on the scenario; fourth, use the LED indicator lights to detect the working status, with the PWR light indicating normal input and the PWR light indicating normal power output. Application Scenarios PoE Splitters are widely applicable in scenarios requiring simplified wiring. Industrial products focus on industrial Internet of Things and security domains. The core application of E-link LNK-INS301 series is to supply power and transmit data for PTZ pan-tilt-zoom cameras in industrial scenarios. It can also be compatible with various industrial edge devices. Its wide temperature range and anti-interference features enable it to operate in harsh environments such as outdoors and industrial control cabinets. The 100-meter transmission distance meets the wiring requirements of industrial sites. The PoE Splitter is an important supporting device for PoE power supply technology, solving the power adaptation problem for non-PoE devices. Industrial PoE Splitters represented by E-link LNK-INS301 series, while maintaining basic functions, enhance environmental adaptability and security. They not only reduce the equipment deployment and maintenance costs in industrial scenarios but also provide more possibilities for the application of PoE technology in the industrial field. They are the preferred accessories for the wiring of industrial Internet of Things devices.

In the context of the rapid development of industrial digitalization and the Internet of Things, PoE (Power over Ethernet) Ethernet power supply technology has become the core solution for the deployment of industrial sensors, security terminals, wireless APs, and other distributed devices. However, traditional PoE technology often has industry pain points such as limited transmission distance and difficulty in powering multiple devices with high power. The 95W industrial-grade PoE extender, as a key device to solve these problems, has multiple functions including power distribution, data relay, and distance expansion. It becomes the preferred choice for point-to-multipoint PoE applications in industrial scenarios. This article takes the E-link LNK-IPE104-90 95W PoE extender as the core example to provide practical reference for industrial network deployment. Core Definition of 95W PoE Extender The 95W PoE extender is a high-power Ethernet power supply expansion device designed for industrial scenarios. Taking the E-link LNK-IPE104-90 as an example, this device is an industrial-grade 1-port 802.3bt PoE++ to 4-port 802.3af/at gigabit PoE extender. Its core breakthrough is to overcome the 100-meter transmission limit of traditional PoE and has both power distribution and data relay functions. The device can obtain a maximum of 95W PoE power from the upstream, providing a total of 75W power to 4 downstream devices without the need for an external power supply. It is the core device for point-to-multipoint PoE applications. Core Value and Key Characteristics Its core value lies in solving the pain points of industrial network deployment, such as cumbersome wiring, limited power supply distance, and difficulty in powering multiple devices. It can expand PoE ports and transmission distance without re-laying cables, significantly reducing construction and operation costs. The core characteristics of this device highlight its industrial-grade high compatibility, equipped with full-gigabit RJ45 ports (1 input 4 outputs), compatible with 802.3af/at/bt full PoE standards; a single extended PoE network can be 100 meters long, with a total expansion distance of up to 400 meters when cascaded with 3 devices, and the output power is intelligently adapted with distance, maintaining a total power of 75W within 101 meters and 65W at 200 meters. It also adopts an IP40 protection aluminum shell, supports a wide temperature range of -40°C to 80°C, is equipped with 6KV surge and 8KV ESD protection, and has excellent switching performance with 10Gbps and 8K MAC table, suitable for harsh industrial environments. Underlying Working Principle The 95W PoE extender operates based on the PSE/PD dual identity design of PoE technology. The device acts as a PD (Power Delivery) receiving end, obtaining 50~57V DC, up to 95W power from the upstream 802.3bt PSE power supply device, and receiving gigabit Ethernet data. Then, it acts as a PSE (Power Supply) transmitting end, using 1/2 (+), 3/6 (-) and other pin allocation methods to support both mid-span and end-span power supply modes. The data is regenerated through the storage-forward mode and transmitted together with the power to the downstream PD (Power Delivery) devices through 4 output ports. When cascaded, each device completes the relay of power and data, thus achieving the maximum 400-meter PoE network transmission. Practical Installation Tips The installation operation of this device is simple and highly compatible with industrial scenarios. The device is pre-installed with DIN rail brackets by default, and also comes with wall-mounted brackets. It supports both DIN rail and wall-mounted installation methods, plug-and-play without complex configuration. Wiring requires the use of Cat5/5e/6 unshielded twisted pair cables. Before installation, it is necessary to test the continuity of the network cable to avoid signal loss. The cascading should be strictly controlled within 3 units to prevent power and signal attenuation. The installation environment must ensure a non-condensing humidity range of 0 to 95%. The equipment can be directly deployed in industrial cabinets or on walls, relying on the aluminum shell for natural heat dissipation, without the need for additional protective measures. Typical Application Scenarios Based on its high power, long-distance, and industrial-grade characteristics, the 95W PoE extender is mainly applied in industrial and security fields. It can directly supply power to industrial sensors, wireless APs, PoE network cameras, and other devices, and is suitable for point-to-multipoint PoE application scenarios in smart factories, park security, industrial power supply systems, etc. It is particularly suitable for industrial sites where rewiring is not possible, and remote security monitoring points. It can achieve flexible deployment of gigabit data transmission and PoE power supply, precisely meeting the power supply and networking requirements of distributed devices in industrial digitalization scenarios. Overall, the 95W PoE extender is a highly practical expansion device for industrial PoE network deployment. Products like the E-link LNK-IPE104-90, which are of industrial grade, leverage core advantages such as high power compatibility, long-distance transmission, and industrial environment resistance, effectively solving the three major problems of wiring, power supply, and distance in traditional PoE deployment. Its simple installation method and flexible cascading capability further reduce the deployment and operation costs in industrial sites.
