Patent ID: 8380063

Claim:
Switched optical fiber network for airplane seats, this network comprising screens connected to each other via an optical fiber, a light signal circulating in this optical fiber to these screens, this network additionally comprising an upstream switching box and a downstream switching box connected in series on the optical fiber to each other, the upstream switching box being positioned upstream of the downstream switching box, at least one screen being connected to each switching box, at least the upstream switching box comprising an optical switch comprising at least one mobile mirror configured to orient the light signal (a) in a first direction when the optical switch is not supplied with power, the first direction sending the light signal unamplified to the downstream switching box, and (b) in a second direction only when the optical switch is supplied with power and thus live, the second direction sending the light signal to the screen connected to the upstream switching box, and means for amplifying the light signal and sending it to the downstream switching box when the upstream switching box is live.
