TERRA FERMA COMPANY HISTORY

Terra Ferma LLC was founded in 2015 to develop and manufacture power products for remote & diverse applications. In 2018 we began to development of PoE Injector cards. Our first version of the Rugged PoE Injector accepts power inputs of 100 to 260VAC and/or input of 10 to 36VDC. We were able to increase output power to 60W @ 56VDC, however no IEEE standards were ratified to that level. We also released a PoE Switch in limited quantities capable of the same 60W @ 56VDC per port. In 2019 Terra Ferma Engineers began development of the RUGGED!+™ PoE Power Supply and RUGGED!+™ PoE Switch.

FREQUENTLY ASKED QUESTIONS

What is PoE?

Power over Ethernet (POE) is a technology that enables network (ethernet) cables to carry electrical power. For example, a security camera or communications radio normally requires two connections be made when installed: A network connection, in order to communicate with video recording and display equipment and a electrical connection to power the camera or radio. In outdoor or difficult to reach environments this can be quite burdensome as expensive power runs would need to be made in order to provide a simple 48VDC for one device.

Does PoE affect the communications speeds of the end device?

No. The low voltages and current of the PoE does not affect communication speeds. The efficiency of powering the device with low voltage DC minimizes losses and heat generated by the device.

Do I need special cables to support PoE?

While Category 5e cables will work for cable runs of less than 300 Meters. It is recommended to use shielded Category 6 cables for optimal performance.

How much power is available through PoE? — What is IEEE Standard 802.3?

IEEE 802.3 PoE Standard specification output voltage of 44VDC to 57VDC. All Terra Ferma products are set to 56.0VDC to minimize current losses while safely supporting all equipment designed to meet IEEE 802.3 PoE Standards.

What if I plug in a non-PoE device into my PoE (Injector) Power Supply?

IEEE 802.3af/at/bt compliant PoE technology is safe. PoE injectors and switches will not damage any equipment, even if the equipment is not designed for PoE applications. Before the PoE (Injector) Power Supply sends any power to a connected Powered Device, the PoE Power Supply initiates a handshake procedure establishing how much power the connected device requires. This procedure uses low voltage and is harmless to any connected device, PoE or non-PoE. If the handshake is completed, the PoE injector or switch begins sending power triggering the Powered Device to start up. If the handshake is not completed for any reason, such as the end device is not an IEEE 802.3 compliant PoE enabled device, the PoE Power Supply never sends any power. It is this built-in feature of all IEEE 802.3af/at/bt compliant devices making PoE technology inherently safe.
