Line 45:

In fiber-to-the-premises systems, the signal is transmitted to the customer premises using [[fiber optic]] technologies. Unlike many conventional telephone technologies, this does not provide power for premises equipment, nor is it suitable for direct connection to customer equipment. An optical network terminal (ONT) is used to terminate the fiber optic line, [[multiplexing|demultiplex]] the signal into its component parts (voice [[telephone]], [[television]], and [[Internet access]]), and provide power to customer telephones. As the ONT must derive its power from the customer premises electrical supply, many ONTs have the option for a [[battery (electricity)|battery]] backup, to maintain service in the event of a [[power outage]].<ref name="whatont" />

== Cleaning ONT Device ==

A [[network interface device]] or the ONT is a costly one. We must place it away from the dust, but we cannot completely block this dust. After some times we should clean the device. Do not use fluid, detergent or spray the outer body, use some soft cloth instead of all such things. Before cleaning makes sure the ONT is Off, remove all the cables carefully, and then clean it with cloth, if possible the use cotton swab dipped in alcohol to clean the optical part. Always keep closing the unused ports with dust caps, or binding tap if dust caps are not available. Dust for a long time inside a port makes it faulty in the long run.<ref>[https://learnfibernetworks.com/huawei-ont-hg8247h/"How to Clean a Network Interface Device"]</ref>
