A system to communicate via modulated optical signals of the Li-Fi signal type to transmit data to and from a plurality of defined privileged spaces. The communicating system includes a plurality of first light sources, each first light source emitting, in the infrared, a first modulated optical signal. A plurality of optical fibers, each optical fiber guiding the first modulated optical signal from a single first light source in the direction of an optical interface. The optical interface transmitting the first modulated optical signal into a defined privileged space. Each optical fiber also transporting a second modulated optical signal from the associated defined privileged space in the direction of a device configured to acquire the second modulated optical signal.

System for communicating via signals of Li-Fi type

A data management structure () on board a transportation device, incorporating a cabin () provided with seats (), includes a data resource block () incorporating audiovisual transmission system units (to), outward communication systems () and/or cabin systems, a standardised data distribution architecture (), and devices (Eto E) for operating said systems. In the structure (), the standardised architecture () includes a concentration box () for the bidirectional transfer, on the one hand, of base signals with the resource block () and, on the other hand, optical signals with the devices (Eto E) of the cabin () on at least one optical fibre (). This concentration box () houses units for processing (to) by signal switching, bidirectional conversion into optical signals, and optical signal management by wavelength allocation and distribution of downstream (F) and upstream (F) optical flows. This concentration box () is connected to the devices (Eto E) of said systems via intermediate boxes () also housing processing units (to) according to the devices (Eto E) to which they are connected.

Method for managing data in a transportation cabin and standardised implementation architecture

The method for on-board electrical power distribution according to the invention includes the producing a protected segregation interface (A) between the primary distribution (A) and the secondary distribution network for electrical power of the cabin system (), referred to as the cabin network, so as to comply with the quality parameters for the primary distribution (A); controlling the extraction of electrical power from the primary distribution (A) by a cabin management system (G, G) depending on the availability of electrical power on this primary distribution (A); converting and distributing this available electrical power in the cabin network () according to a suitable configuration of the loads () of this cabin network () and defined according to an electrical configuration of type, single/three-phase AC and DC, as well as of voltage level and frequency.

The invention relates to optimize the use of electronic cabinets in connector technology, using simplified internal connector technology and flexibility in adapting the external connector technology to the connectors of the cabling assemblies&#x2014;electronic and/or optical connector technologies&#x2014;and on the structurally. To this end, according to an embodiment, an overall box-shaped electronic cabinet () that is fitted with at least one detachable interconnection module () is provided with a bottom wall () including a bottom card () connected to a set of electronic modules (). The rear wall () is extended by edges () provided with connectors (C, C) that are capable of being coupled to the connectors (C, C) that are arranged on a side surface () of the detachable interconnection module () (). Devices for closing and releasably locking the at least one detachable interconnection module () are provided between a handle () of an interconnection module () and the side wall () of the cabinet ().
