Optical Network Terminal Ont Onu

These electrical signals are then sent to individual subscribers.

Optical network terminal ont onu.

Ont is also known as optical network unit onu. A passive optical network is a form of fiber optic access network. Optical network unit onu optical network terminal ont onu converts optical signals transmitted via fibers to electrical signals. In general there is a distance or other access network between onu and end user s premises.

Furthermore onu can send aggregate and groom. The optical network terminal ont converts the optical signal coming through the fiber into separate signals for tv voice and data. The ont converts optical signals into electrical signals and vice versa. The cisco me 4600 series offers network service providers a flexible and cost effective approach for optical fiber access solutions over active or passive optical network architectures.

A smartjack is a type of nid with capabilities beyond simple electrical connection such as diagnostics. Ont is an itu t term while onu is an ieee term. A small difference between them might be the application locations. The cisco me 4600 series optical network terminal ont portfolio offers an exceptionally broad and scalable solution.

These electrical signals are then sent to individual subscribers. Australia s national broadband network uses the term network termination device or ntd. Ont means optical network terminal olt use fiber cables adapters and others to connect with onu and ont in order to build odn optical distribution network both of onu and ont are client side devices no difference in nature but if you have to distinguish it can be seen from the name difference ont is the optical network terminal applied. Onu ont optical network unit and optical network terminal onu converts optical signals transmitted via fiber to electrical signals.

The onu serves as a media converter interfacing the fiber circuit to embedded copper in the form of unshielded twisted pair utp in a telco network and coaxial cable in a catv network the onu physically is positioned between the optical line terminal olt at the network edge and the optical network terminal ont at the customer premises. They both refer to the user side equipment in gpon network. The ont is the demarcation point between the leverettnet fiber optic network and the subscriber premises ethernet wiring to the subscriber router which serves the subscriber s devices. In general there is a distance or other access network between onu and end user s premises.

A pon reduces the amount of fiber and central office equipment required compared with point to point architectures. The ont is a network interface device used with fiber optic systems. An optical network terminal ont is a type of nid used with fiber to the premises applications. The ont is installed with fios service on either the outside or inside of your home garage basement closet etc.
