Optical Network Unit Definition

Disclosed is a dmt discrete multi tone system including a first onu optical network unit receiver connected to a first transmission line from a remote site transmitter and a second onu receiver connected to a second transmission line for receiving data signals to which fext far and crosstalk from the first transmission line is combined.

Optical network unit definition. Depending on where the pon terminates the system can be described as fiber to the curb fiber to the building fttb or fiber to the home a pon consists of an optical line termination olt at the communication company s office and a number of optical. 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. Optical network unit is a modem cum router which converts optical signals into digital signal it is a part of optical ethernet network using gpon epon architecture and is installed at the end point on the user side giving him services like voip catv high speed internet find here online price details of companies selling optical network unit onu router gpon onu at best price in india. Ad net 4 fast ethernet port onu optical network unit functional design and chassis configuration of ont vary depending on customer needs and requirements.

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. A passive optical network pon is a system that brings optical fiber cabling and signals all or most of the way to the end user. Australia s national broadband network uses the term network termination device or ntd.

A gpon network consists of olt optical line terminals onu optical network unit and a splitter. Generically an nid may also be called a network interface unit niu telephone network interface tni system network interface sni or telephone network box. The splitter will divide the signal when needed. The size of it can range from simple small box being attached outside the house to large unit mounted inside the large office building or apartment complex.

The olt takes in all of the optical signals in the form of beams of light from onus and will convert it to an electrical signal. A pon reduces the amount of fiber and central office equipment required compared with point to point architectures. Olts normally support up to 72 ports. Optical network unit.

Now the question arises that what is the need for the optical network when we have other communicating networks. A passive optical network is a form of fiber optic access network. So optical networks are used in order to have optical signal transmission. It utilizes optical fiber cables as the primary communication medium for converting data and passing data as light pulses between sender and receiver nodes.

An optical network is a type of data communication network built with optical fiber technology. So the answer to this question basically relies on the ease of transmitting the signal in the form of light pulses.
