E-link PoE Switche

When it comes to long-distance security protection and the networking of outdoor IoT devices, common problems include insufficient transmission distance of network cables, high difficulty in on-site operation and maintenance, and cumbersome power supply for multiple high-definition devices.

To address these challenges, E-link has independently developed the LNK-AI2500MP-SFP AI intelligent management PoE optical fiber transceiver, which integrates 2.5G high-speed transmission, 95W high-power PoE power supply, and mobile terminal visual operation capabilities. The LNK-AI2500MP-SFP provides a one-stop solution for optical and electrical conversion of long-distance fibers and terminal power supply management, significantly reducing the costs of project wiring, debugging, and later maintenance. It is suitable for the construction of industrial and commercial monitoring networks in all scenarios.

What is the product?

The LNK-AI2500MP-SFP is an AI intelligent management type 2.5G PoE optical fiber transceiver independently developed by E-link. It is a type of optical-electrical conversion transmission equipment, equipped with 1 10/100/1000/2500M adaptive RJ45 electrical ports and 1 1.25G/2.5G compatible SFP optical ports.

The LNK-AI2500MP-SFP has an internal IEEE 802.3af/at/bt standard PoE++ power supply module, with a maximum output power of 95W. Without the need for additional power supply equipment, it can simultaneously transmit data and power to IP cameras, wireless APs and other terminals. Different from traditional unmanaged transceivers, it supports mobile phone APP and computer Web visual intelligent control, and comes with a digital screen to display real-time equipment operating parameters.

Working Principle

The core of the LNK-AI2500MP-SFP accomplishes the bidirectional conversion between electrical signals and optical signals. The Ethernet electrical signals transmitted through the twisted pair are modulated by the internal chip into optical signals, which are then transmitted over long distances through the SFP optical module; the receiving end equipment then demodulates the optical signals back into Ethernet electrical signals, achieving long-distance network extension via optical fibers.

The PoE module simultaneously supplies 44-58V direct current power to the downstream power-receiving devices through the network cable, and the data and power are transmitted on the same line. The built-in AI monitoring chip continuously collects DDM data such as the overall voltage, current, temperature, and transmit/receive power of the optical module, and synchronizes it to the local digital screen and management terminal. When parameters are abnormal, it automatically triggers an optical power alarm to ensure the stability of the link.

Installation and Usage Steps

• Hardware Installation: Insert the corresponding rate SFP optical module into the F1 optical port of the device. Connect the fiber optic ends to this device and the fiber optic switch in the machine room respectively; Use an Ethernet cable of Category 5 or higher to connect the P1 electrical port to the PoE power receiving terminal; Connect to the matching 44-58V DC power adapter for power supply.
• DIP Switch Debugging: Use the 4-bit DIP switch on the device body to enable LFP link fault transfer, or force the optical port to lock at a 1.25G rate, adapting to different fiber link configurations.
• Intelligent Management: Scan the QR code on the device body to download the accompanying E-link management APP, or access the Web management page via a computer, automatically identify the device and view real-time data such as port rate, optical power, PoE power consumption, etc., customize the optical power alarm threshold, and set the device to restart at regular intervals.
• Status Verification: Observe the indicator lights on the device body. The green SYS light flashing slowly indicates normal device operation, while the red F1ALM light is constantly on, indicating that the received optical power is below the set threshold. This requires troubleshooting of the fiber link fault.

Importance and Key Features

The core value of this LNK-AI2500MP-SFP lies in integrating three key capabilities: high-speed transmission, high-power PoE, and lightweight intelligent operation and maintenance. It breaks away from the limitation of traditional transceivers that rely on professional instruments for on-site debugging. In terms of speed, it supports 2.5G full adaptive mode, and the large cache ensures no lag in multi-channel 4K surveillance footage. The power supply covers a full power range from 15.4W to 95W, and is compatible with various high-definition dome cameras and industrial wireless gateways.

The intelligent management function enables remote reading of the complete DDM diagnostic information of the optical module, and allows for customizing alarms and scheduled restarts to reduce the frequency of on-site inspections. The industrial-grade aluminum body is paired with a wide operating temperature range of -20℃ to 70℃, providing dust-proof and anti-interference capabilities.

The LNK-AI2500MP-SFP operates continuously without interruption for 7×24 hours, with an MTBF (Mean Time Between Failures) of over 200,000 hours. It is suitable for outdoor harsh environments and supports both desktop placement and centralized rack deployment, enabling flexible networking for various projects of different sizes.

Application Scenarios

The LNK-AI2500MP-SFP is widely compatible with various long-distance wired monitoring and IoT transmission projects. Outdoor scenarios include forest fire monitoring, river and water area monitoring, highway and urban road security, and equipment networking along railway and urban rail lines; industrial scenarios cover petrochemical plants and data collection from automated equipment; commercial scenarios are suitable for high-end office buildings, park wireless AP power supply transmission, and can also be used for high-definition monitoring in parking lots and hotels.

In projects with limited fiber resources and no independent power supply points for terminals, it has significant advantages, as a single device can complete the functions of photoelectric conversion, terminal power supply, and remote operation, simplifying the overall network architecture.

The LNK-AI2500MP-SFP AI intelligent management PoE optical transceiver breaks through the technical barriers of high-speed optical fiber transmission and intelligent operation and maintenance. It takes into account transmission performance, power supply capacity and lightweight management, and compresses project costs throughout the entire process from initial wiring construction to later operation and maintenance.

It is a cost-effective core transmission device in the AI era for long-distance monitoring and industrial Internet of Things networking, capable of meeting the long-term stable network transmission needs of multiple industries.
