Fiber to the Desk with PoE
In this application example, a fiber-to-the-desk network is deployed to leverage the security, bandwidth and distance benefits of fiber optic cabling.
The network originates from a fiber switch in the building's main data closet (or it can be a UTP switch and a chassis of copper-to-fiber media converters). Fiber optic cables run to each office/desk, where they are terminated by OmniConverter media converters that are powered by an AC or DC power source. The media converters provide fiber to copper media conversion, plus Power over Ethernet (PoE) via UTP cabling. IP phones and video conferencing equipment powered by PoE are known as Powered Devices (PDs). OmniConverter media converters can power a variety of IEEE compliant and non-IEEE compatible PDs.
OmniConverter media converters also support PoE+ for desktop devices that require up to 25.5W of power.
Devices that do not receive power via PoE, such as PCs, thin clients and laptops, can be connected to PDs, and they will receive data only (no power), as shown in OFFICE 1 in the illustration below. OmniConverter media converters automatically detect whether or not a connected device is a PD, so non-PD devices can also be safely connected directly to the media converters.
