| 单词 | ONT (Optical Network Terminal) |
| 释义 | ONT (Optical Network Terminal) In a passive optical network (PON), the device that terminates the optical local loop at the customer premises in a fiber-to-the-premises (FTTP) scenario. The ONT serves as a media converter, interfacing the optical fiber to the copper-based inside wire. The ONT is an addressable device that recognizes and accepts downstream data addressed to it specifically, ignoring all other data. The ONT is synchronized with the optical line terminal (OLT) at the network edge and is assigned time slots for user-generated upstream data, which it buffers as necessary. See also buffer, downstream, FTTP, local loop, media converter, OLT, optical fiber, PON, synchronize, and upstream. |
