An OTU (Optical Transport Unit) frame is a data structure that an OTN Terminal (or Source STE) will use to transport its data to the outside world. This post will call any entity that generates and transmits OTUk frames a Source STE (Section Terminating Equipment). Likewise, we will call any entity that receives, processes, and terminates OTUk.

The Optical Master Unit (OMU) is used to convert signals from RF to light when fibre fed repeaters are used. The OMU is most often connected to a base station. In these cases, an RF coupler is used to couple off signals that are fed into the OMU. An entry shelf unit can also be used in cases when the base station and the OMU are not located.

An optical transport network ( OTN) is a digital wrapper that encapsulates frames of data, to allow multiple data sources to be sent on the same channel. This creates an optical virtual private network for each client signal. ITU-T defines an optical transport network as a set of optical network elements (ONE) connected by optical fiber links.

Another way to measure coding gain is with a plot of BER vs. Eb/N0. Eb is the bit energy and can be described as signal power (S) times the bit time Tb. N0 is the noise power spectral density and can be described as the noise power (N) divided by the bandwidth (W). Thus Eb/N0 is equal to SNR * (Bandwidth/Bit Rate).

May 17, 2023. An optical network terminal (ONT), sometimes also known as an ONU (optical network unit), is a device utilised for optical fibre-based telecommunications. They work in a similar way to a modem but instead of using a traditional digital/analogue transmission method they use fibre optic cables to bring a fibre-optic internet.
