Remote powering is supported using a centrally located bulk power plant, emergency power and bulk battery back-up over composite single-mode
fiber (greenfield), which provides two copper wires or repurposes existing CATx cabling (brownfield).
Power over Ethernet (PoE)
Both IEEE 802.3af PoE and high-power PoE+ IEEE 802.3at, including Class-4 negotiations can be selected on per port basis. The maximum PoE power is 60 watts, spread across all four Ethernet ports.
The Tellabs 140W ONT is modular in design so that its ONT back box with power connectors and fiber cable slack storage can be installed separately. The ONT back box, with remote DC power termination, can be installed into a singleor dual-gang form factor. This modular design allows for separate installation of DC power and fiber cable during the rough construction phase, while ONT electronics, fiber connectivity and the ONT faceplate can be installed during the finish construction phase. Another benefit of the ONT back box (with DC power termination and fiber cable slack storage) is that it can be installed in preparation for future growth considerations (cover with standard blank faceplate) without incurring the expense of purchasing ONT electronics and an ONT faceplate.
