E-link PoE Switche

In long-distance industrial and security scenarios, there are often challenges such as limited transmission distance of network cables, difficulties in obtaining power from remote devices, and cumbersome fault troubleshooting.

The E-link self-developed LNK-AI3011MP-SFP series of AI intelligent management PoE optical converter integrates three core capabilities: gigabit optical transmission, 95W high-power PoE power supply, and mobile/web-based visual operation and maintenance. It solves the problems of wiring, power supply, and equipment management in one go, and is suitable for various long-distance monitoring networking requirements in the AI era.

What is the product?

The LNK-AI3011MP-SFP series is an AI intelligent management PoE optical converter independently developed by E-link. It is equipped with 1 10/100/1000M adaptive RJ45 electrical port and 1 100/1000M adaptive SFP optical port, compatible with all series of IEEE 802.3af/at/bt PoE standards, with a maximum output of 95W PoE++ power supply, and comes with a digital display screen and intelligent operation and maintenance system.

The LNK-AI3011MP-SFP series can be used without the need for professional testing instruments to view real-time equipment operation, optical module DDM data, etc. It is an industrial-grade network conversion device that integrates transmission, power supply, and remote management.

Working principle

The core of the LNK-AI3011MP-SFP series completes the bidirectional conversion of electrical signals and optical signals. The electrical port end serves as the PoE power output end at the same time, and synchronously transmits gigabit data and 44-58V DC power through a single network cable; the SFP optical port uses optical fibers to achieve long-distance signal transmission without electromagnetic interference.

The built-in AI management chip collects data such as overall voltage, current, temperature, optical module reception and transmission power, and port link status, and synchronously pushes it to the local digital screen, mobile APP, and web management interface. The LNK-AI3011MP-SFP series has built-in threshold alarms, timed restart, and PoE power-on/off logic, and automatically triggers audible and visual alarms when parameters are abnormal, achieving visual monitoring of the entire link status.

Installation and usage steps

• Power supply connection: Select a 44-58V DC power supply and connect it to the 5.5×2.1mm power interface of the device. Confirm that the SYS indicator light flashes slowly to indicate that the device has started normally.
• Link connection: Insert the matching single-mode/multi-mode optical module into the SFP slot, and connect the optical fiber to the fiber optic switch in the machine room; connect the RJ45 electrical port to the power-receiving terminals such as PoE cameras and wireless APs through six-category network cables.
• Management and debugging: Scan to download the accompanying APP or log in to the web management interface with a computer, and one-click read parameters such as optical power and device temperature. Customize the optical power alarm threshold, set timed restart and PoE power-on/off periods.
• Function calibration: Turn on the LFP link fault forwarding function through the on-board switch, check the status of the F1ALM alarm light. A red light constantly on indicates that the received optical power is below the safety threshold, and replace the compatible optical module in time.
• Deployment fixed: Place it on a desktop in a small-scale scenario, or install it uniformly in standard 14-slot racks in a batch machine room.

Importance and key features

The core value of this LNK-AI3011MP-SFP series lies in significantly reducing the construction and operation costs of long-distance networking, eliminating the need to separately lay power cables, and providing a visual operation and maintenance mode that enables non-professionals to quickly troubleshoot faults.

The core features include an industrial-grade wide-temperature aluminum body that can operate stably within -20℃ to 70℃; a store-and-forward switching architecture that supports 9K ultra-large frame forwarding, ensuring stable data transmission; complete SFPDDM optical module detection function to accurately grasp the fiber link loss; multiple real-time alarm mechanisms to prevent network disconnection failures in advance; supports 30W/60W/95W power models for selection, covering low-power wireless APs and high-power high-speed dome cameras and other types of terminals.

The overall power consumption of the LNK-AI3011MP-SFP series does not exceed 3W, with an MTBF of over 200,000 hours, and is compliant with CE, FCC, and RoHS certifications, suitable for harsh industrial outdoor environments.

Application scenarios

The LNK-AI3011MP-SFP series is applicable to various scenarios such as outdoor monitoring, industrial production, urban infrastructure, and commercial buildings. For forest fire prevention and water body monitoring, long-distance transmission via optical fibers combined with PoE power supply is adopted, eliminating the need for separate power supply equipment at remote locations. For high-speed and urban road monitoring, as well as camera groups along railway tracks, network formation relies on a wide-temperature anti-interference body to adapt to outdoor temperature differences and electromagnetic interference environments.

For automated monitoring equipment in petrochemical plants, optical fibers are used to isolate industrial electromagnetic interference to ensure uninterrupted data transmission. For high-end office buildings and parks, the equipment extends the building network, providing unified power supply for wireless APs and surveillance cameras, simplifying indoor wiring projects.

The LNK-AI3011MP-SFP series features AI visualization management, high-power PoE, and gigabit long-distance optical transmission as its core advantages. It addresses the pain points of the “transmission – power supply – operation and maintenance” entire process in long-distance networking, balancing performance stability and ease of operation. It is a cost-effective networking solution for smart cities, industrial automation, and outdoor security projects.
