Overcome PoE limitations with the Ubiquiti FiberPoE

Overcome PoE limitations with the Ubiquiti FiberPoE

The FiberPoE is a low-cost solution for outdoor deployments that require long-distance runs to reach the PoE device. Deployments with the FiberPoE also provide significant EMI and ESD protection over typical PoE installations.


Still not convinced? Let’s look a little closer at the features:


Separate Data and Power Transport

PoE is ideal for indoor or short-run installations. However, for outdoor, long-distance installations, PoE becomes vulnerable to EMI and is limited to 100 meters with correlated power loss. With the FiberPoE, data and power are transported on separate cables to greatly improve data integrity and enable much longer cable runs.


The FiberPoE provides Gigabit bi-directional data transport between twisted-pair Ethernet cable and fiber optic cable and injects DC power to the Ethernet cable for passive PoE. Use one FiberPoE device as a FibertoEthernet Converter, or a pair of FiberPoE devices to create a Fiber Bridge.


Fiber Optic Data Transport

Using fiber optic cable for data transport significantly reduces electrostatic discharge (ESD) failures and electromagnetic interference (EMI). Data integrity is also sustained in runs beyond 100 meters, the limit of Ethernet over twisted-pair cable.


The FiberPoE supports a 1G SFP module and 24V or 50V power from a DC power cable or PoE cable.


Integrated Fiber Cable Strain Relief

An integrated strain relief system was thoughtfully designed to fit inside the FiberPoE cover for added protection and a cleaner installation.


Power Options

The FiberPoE provides passive PoE power to the PoE device. Options for providing power to the FiberPoE include:

  • DC Power: Connect a 24VDC or 50VDC power cable to the Terminal Block.
  • PoE (Power Only): Connect an Ethernet cable with 24V or 50V (4-pair) PoE to the DC In RJ45 port.
  • PoE (Power and Data): Connect an Ethernet cable with 24V or 50V (4-pair) PoE to the PoE RJ45 port.


Application Examples

The following are typical use cases for the FiberPoE.

Data Options:

  1. Fiber-to-Ethernet Converter One FiberPoE at the top of the tower is used to convert fiber to Ethernet at the radio. At the base of the tower, the fiber optic cable connects directly to a fiber switch or router.


  1. Fiber Bridge Two FiberPoE devices, one at the base and one at the top of the tower, are used to provide a fiber optic data link for protection from EMI events that can cause equipment damage or signal integrity issues.
