Abstract
A data management structure (1a) on board a transportation device, incorporating a cabin (100) provided with seats (110), includes a data resource block (210) incorporating audiovisual transmission system units (211 to 213), outward communication systems (100) and/or cabin systems, a standardised data distribution architecture (10a), and devices (E1 to E4) for operating said systems. In the structure (1a), the standardised architecture (10a) includes a concentration box (11) for the bidirectional transfer, on the one hand, of base signals with the resource block (210) and, on the other hand, optical signals with the devices (E1 to E4) of the cabin (100) on at least one optical fibre (2, 3; 2a, 2′a; 2b). This concentration box (11) houses units for processing (211 to 213) by signal switching, bidirectional conversion into optical signals, and optical signal management by wavelength allocation and distribution of downstream (F1) and upstream (F2) optical flows. This concentration box (11) is connected to the devices (E1 to E4) of said systems via intermediate boxes (30, 40) also housing processing units (111 to 113) according to the devices (E1 to E4) to which they are connected.
