The UF-IS104GPD-EX is a compact industrial PoE-powered Gigabit fiber media converter designed to extend both Ethernet data and PoE power from a remote fiber network to multiple downstream PoE devices.

It provides one 100/1000BASE-X SFP fiber port and four 10/100/1000BASE-T RJ45 ports. One RJ45 port is used as the upstream IEEE 802.3bt PoE input, while the other three RJ45 ports provide PoE passthrough to downstream devices.

Powered directly by an upstream PoE switch or PoE injector, the converter requires no local AC power adapter. Each PoE output supports up to 30W, with a total PoE output budget of up to 60W, allowing the device to connect and power multiple IP cameras, wireless access points and other PoE equipment.

With a fanless IP40 aluminum housing, -40°C to +75°C operating temperature and DIN-Rail or wall-mount installation, the UF-IS104GPD-EX is designed for industrial Ethernet, smart surveillance, wireless networking and remote edge deployments.

How Does PoE Passthrough Work?

The UF-IS104GPD-EX works as a PoE-powered network edge device. Instead of using a local AC or DC power adapter, it receives both Ethernet data and electrical power from an upstream IEEE 802.3bt PoE switch or PoE injector.

The basic connection is:

PoE Switch / PoE Injector → PoE IN → UF-IS104GPD-EX → PoE OUT → Downstream PoE Devices

At the same time, the SFP port can provide a fiber uplink for long-distance network connectivity.

The converter distributes PoE power to three downstream RJ45 ports. Each PoE output supports up to 30W, with a total PoE output budget of up to 60W.

This architecture allows multiple PoE devices to be deployed at a remote network edge without installing a separate local power supply for the media converter.

What Problems Does the UF-IS104GPD-EX Solve?

Problem 1: No Local Power Outlet at the Remote Network Edge

Remote cameras and network devices may be installed where AC power is difficult or expensive to provide.

Solution:
The UF-IS104GPD-EX receives power directly from an upstream IEEE 802.3bt PoE switch or injector, eliminating the need for a local power adapter.

Problem 2: Fiber Connectivity Is Required at the Remote Site

Standard PoE extenders may only provide copper Ethernet connectivity.

Solution:
The integrated 100/1000BASE-X SFP port provides a fiber uplink for connecting remote network segments over optical fiber.

Problem 3: Multiple PoE Devices Need to Be Connected at One Remote Location

Using a separate PoE extender for every device can increase installation complexity.

Solution:
The UF-IS104GPD-EX provides three PoE output ports, allowing multiple downstream PoE devices to be connected from one compact industrial unit.

Problem 4: A Separate Power Supply Increases Installation Cost

A conventional fiber converter may require a local AC/DC adapter.

Solution:
Because the converter is powered through PoE, no separate local power adapter is required.

Problem 5: The Installation Environment Is Harsh

Commercial networking equipment may not be suitable for industrial temperature conditions.

Solution:
The fanless aluminum enclosure, IP40 protection and -40°C to +75°C operating temperature make the converter suitable for industrial and remote installations.

PoE IN and PoE OUT

The UF-IS104GPD-EX uses a dedicated PoE input port and three PoE output ports.

PoE IN:
Receives Ethernet data and power from an upstream IEEE 802.3bt PoE switch or PoE injector.

PoE OUT 1–3:
Provides Ethernet data and PoE power to downstream devices. Each output supports up to 30W, with a combined PoE output budget of up to 60W.

SFP Fiber Port:
Provides 100Mbps or Gigabit optical uplink connectivity using a compatible SFP transceiver.

This architecture combines fiber media conversion, PoE powering and multi-port PoE extension in one compact industrial device.

VLAN Function for PoE Edge Devices

The UF-IS104GPD-EX provides a DIP-switch-configurable VLAN function for the three PoE output ports.

When VLAN mode is enabled, the PoE output ports can be isolated from each other at Layer 2 while maintaining communication with the upstream network.

This function can help reduce unnecessary traffic between downstream PoE devices and improve network segmentation in IP surveillance and other multi-device edge deployments.

The VLAN function can be enabled or disabled through the DIP switch according to the application requirements.
