In the current era of widespread adoption of Power over Ethernet (PoE) technology, a single Ethernet cable can achieve both data transmission and power supply, significantly simplifying the wiring process for devices. The PoE Splitter, as the core component that connects the PoE power supply system with non-PoE devices, has become an important choice in industrial and security scenarios. The E-link LNK-INS301 series Industrial PoE + Splitter is a typical representative of such devices. This article will elaborate on the core contents such as the definition, operation, and application of the PoE Splitter based on its functional characteristics. What is a PoE Splitter A PoE Splitter is a power receiving end (PD) device. Its core function is to separate the mixed data signals and power in the PoE cable, providing data connections and direct DC power supply for non-PoE terminal devices. The E-link LNK-INS301 series is an Industrial Gigabit PoE + splitter that complies with IEEE 802.3af/at standards. It can convert PoE input into a 19VDC/20W power output, specifically designed for non-PoE devices in industrial scenarios, enabling independent supply of data and power. 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.

Mid-Autumn / Mooncake Festival Introduction   Mid-Autumn Festival / Mooncake Festival   Mid-Autumn Festival is also called Mooncake Festival or Moon Festival.   Mid-Autumn Festival is held on the 15th day of the eighth month of the Chinese calendar, which is in September or early October in the Gregorian calendar.   Mid-Autumn falls as early as September 8th (2033) and as late as October 6th (2025) in the next 30 years.   3-Day Break for Mooncake Festival   Normally, Chinese people will have a three-day "public holiday" on the Mid-Autumn Festival — a normal weekend off for 5-day week workers, however...   When Mid-Autumn occurs at the end of September or early October its statutory day of public holiday is usually combined with the statutory National Day.   Why Mid-Autumn Is Celebrated at Month 8 Day 15   Traditional Calendar Seasons   According to the Chinese lunar calendar (and traditional solar calendar), the 8th month is the second month of autumn. As the four seasons each have three (about-30-day) months on the traditional calendars, day 15 of month 8 is "the middle of autumn".     For the Full Moon   On the 15th of the lunar calendar, each month, the moon is at its roundest and brightest, symbolizing togetherness and reunion in Chinese culture. Families get together to express their familial love by eating dinner together, appreciating the moon, eating mooncakes, etc. The harvest moon is traditionally believed to be the brightest of the year.   For Harvest Celebration Month 8 day 15, is traditionally the time rice is supposed to mature and be harvested. So people celebrate the harvest and worship their gods to show their gratitude.   Mid Autumn Festival       E-link wish all have a great day! !  

2022 was the sixth-warmest year on record based on NOAA’s temperature data. This warmness caused long maintenance of the outdoor temperature more than 40 degrees Celsius and it is starting to damage the network switches installed and operating outdoors. Now it is required for network switch to endure the operating heat as well as the outdoor environment heat which is a quite burden for the network implementors. However, E-link can resolve your issues on this. E-link’s Industrial Ethernet switch and PoE switch have strong performance even under the severe temperature condition. It can be the right solution for you to protect your network infrastructure from the environment.
