Optical Network Terminal Ont Onu

Ont is an itu t term while onu is an ieee term.

Optical network terminal ont onu.

They both refer to the user side equipment in gpon network. In general there is a distance or other access network between onu and end user s premises. A small difference between them might be the application locations. A passive optical network consists of an optical line terminal olt at the service provider s central office hub and a number of optical network units onus or optical network terminals onts near end users.

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. Furthermore onu can send aggregate and groom. 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. The ont is a network interface device used with fiber optic systems.

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. A smartjack is a type of nid with capabilities beyond simple electrical connection such as diagnostics. Ont is also known as optical network unit onu.

Australia s national broadband network uses the term network termination device or ntd. 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. Onu can work in different temperature and weather conditions.

A pon reduces the amount of fiber and central office equipment required compared with point to point architectures. The ont is installed with fios service on either the outside or inside of your home garage basement closet etc. The optical network terminal ont converts the optical signal coming through the fiber into separate signals for tv voice and data. 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.

The ont terminates the fiber optic line in an inner compartment. Onu ont optical network unit and optical network terminal onu converts optical signals transmitted via fiber to electrical signals. The ont converts optical signals into electrical signals and vice versa. These electrical signals are then sent to individual subscribers.
