Tellabs 180C ONT powering options include both local AC and remote DC. For local AC power, power adaptors are used to transform 120 AC power from the wall plug to 48 DC power delivered to the ONT. For the remote DC power option, a centrally located bulk rectifier can be used, and 48 VDC power is delivered over CATx cables or new hybrid fiber/copper cables. Remote powering option uses a centrally located bulk power plant, emergency power and bulk battery back-up. For local powering option, the Tellabs PSU BBU unit with monitoring can be used as a local battery back-up. The ONT180C has both Phoenix and Molex connectors for power.
Power over Ethernet (PoE)
For Power over Ethernet (PoE), IEEE 802.3af PoE, PoE+ IEEE 802.3at (Class-4 negotiations) and IEEE 802.3bt (4PPOE) can be selected on per port basis. The maximum PoE power when local powered is 120 watts and the maximum PoE power when remote powered is 100 watts.
