Optical Network Terminal Ont Onu

A pon reduces the amount of fiber and central office equipment required compared with point to point architectures.

Optical network terminal ont onu.

Ont is an itu t term while onu is an ieee term. The ont is a network interface device used with fiber optic systems. The ont is installed with fios service on either the outside or inside of your home garage basement closet etc. Ont is also known as optical network unit onu.

A passive optical network is a form of fiber optic access network. Onu ont optical network unit and optical network terminal onu converts optical signals transmitted via fiber to electrical signals. In general there is a distance or other access network between onu and end user s premises. These electrical signals are then sent to individual subscribers.

A small difference between them might be the application locations. They both refer to the user side equipment in gpon network. 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.

In general there is a distance or other access network between onu and end user s premises. Australia s national broadband network uses the term network termination device or ntd. The cisco me 4600 series optical network terminal ont portfolio offers an exceptionally broad and scalable solution. The ont converts optical signals into electrical signals and vice versa.

A smartjack is a type of nid with capabilities beyond simple electrical connection such as diagnostics. The ont terminates the fiber optic line in an inner compartment. 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. Onu can work in different temperature and weather conditions.

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. An optical network terminal ont is a type of nid used with fiber to the premises applications. Optical network unit onu optical network terminal ont onu converts optical signals transmitted via fibers to electrical signals. These electrical signals are then sent to individual subscribers.
