Unmanaged industrial PoE fiber switch with 2*10/100/1000M PoE ports and 1*1000M uplink single-mode dual-fiber(1310nm) SC optical module. Port 1-2 support IEEE802.3af/at PoE standard. It can support dual DC redundant power input (Phoenix terminal connection) and DIN rail mounting.



The DARWIN-S138IB030001 is a full gigabit industrial PoE fiber switch independently developed. It has 2*10/100/1000Base-T RJ45 ports and 1*1000Base-X SC single-mode dual-fiber optical module (optional single-mode/multi-mode, single-fiber/dual-fiber optical module). Port 1-2 can support IEEE802.3af/at standard PoE. Single port PoE power is 30W. As a PoE power supply device, it can automatically detect and recognize power-compliant devices that meet the standard and supply power through the network cable. It can supply power to POE terminal equipment such as wireless AP, webcam, VoIP, industrial sensor through the network cable, and meet the network environment that needs high-density PoE power supply. It is suitable for intelligent transportation, rail transit, power industry, mining, petroleum, maritime, metallurgy, and Industrial scenarios such as green energy construction build cost-effective, stable, and reliable communication networks.




Gigabit line speed access, Gigabit optical port uplink

◇ Support Gigabit Ethernet port and Gigabit SC optical port combination, which enables users to flexibly build networking to meet the needs of various scenarios.

◇ Support non-blocking wire-speed forwarding.

◇ Support full-duplex based on IEEE802.3x and half-duplex based on backpressure.



Intelligent PoE power supply

◇ 2*10/100/1000Base-T RJ45 ports, meeting the needs of security monitoring, teleconferencing system, wireless coverage, and other scenarios.

◇ IEEE802.3af/at PoE standard, without damaging non-PoE devices.

◇ Priority system for PoE port, it will supply power to the high priority level port first when the power budget is insufficient and avoid overwork of the device.


Stable and reliable

◇ Low power consumption, No fan, aluminum shell.


◇ The user-friendly panel can show the device status through the LED indicator of PWR, Link, PoE.
