Abstract: The invention relates to the on-board electric power network architecture of a vehicle cabin using domestic devices, in particular of an aircraft cabin, including primary networks (11, 12) connected in parallel to a single domestic network (3) of the cabin for powering domestic devices via converter units (41, 42; 40). Measurement sensors (80) are arranged at the output of each converter unit (41, 42; 40) and the measurements are transmitted (L1) to a regulating device (9) for sharing the supply of the domestic network (3) according to the available power, each converter unit (41, 42; 40) comprises an upstream processing stage (E1) and a downstream processing stage (E2), each including an anti-disturbance device (D1, D2), linked (B1, B2) with the primary network (11, 12) and linked (B3, B4) with the domestic network (3), respectively. The anti-disturbance devices (D1, D2) are coupled with a set (7) of domestic level adapters (71, 72) distributed in the processing stages (E1, E2), the set of adapters (7) likewise including a neutral-line separator (73).

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.

Abstract: A passive optical communication network includes two optical line terminals configured respectively to receive a communication signal from information systems and at least two optical network units configured to receive the communication signal. At least two optical switches, one part of which is connected at input to a first terminal via a primary nominal operating path and to the second terminal via a secondary path, and the other part of which is connected at input to a second terminal via a primary nominal operating path and to the first terminal via a secondary path. Each switch being connected at output to at least one optical network unit. A command controller connected to the switches and configured to control the switches such that, when a fault is detected on a primary path, the switch associated with the path is toggled.
