First Claim
1. A system to manage an optical link in free-space to communicate data via an aqueous medium, comprising:
- a seismic data acquisition unit positioned on a seabed in the aqueous medium, the seismic data acquisition unit comprising;
one or more sensors to detect acoustic waves that indicate subsurface lithologic formations or hydrocarbon deposits;
a seismic data recorder to record seismic data corresponding to the acoustic waves detected by the one or more sensors; and
a first link manager agent of the seismic data acquisition unit to;
receive, through the aqueous medium from a second link manager agent of an underwater vehicle, a default optical transmission;
transmit, responsive to receipt of the default optical transmission, through the aqueous medium to the second link manager agent of the underwater vehicle, a first optical transmission at a first output level, the first optical transmission comprising a first packet corresponding to a network protocol, the network protocol comprising at least one of a user datagram protocol (UDP) and a transmission control protocol (TCP);
receive, subsequent to transmission of the first optical transmission at the first output level, one or more additional default transmissions from the underwater vehicle having a same parameter as the default optical transmission previously received from the underwater vehicle;
determine, responsive to receipt of the one or more additional default transmissions having the same parameter, that the second link manager agent failed to receive the first packet via the first optical transmission;
transmit, responsive to failure of the first optical transmission, a second optical transmission at a second output level different than the first output level, the second optical transmission comprising a second packet corresponding to the network protocol;
identify that the second packet was successfully received by the second link manager agent; and
establish, responsive to the identification that the second packet was successfully received, the second output level as a transmission output level for the seismic data acquisition unit.

Abstract
The present disclosure provides optical link management in a marine seismic environment. A first device can transmit, to a second device, a first optical transmission at a first output level. The first optical transmission can include a first packet corresponding to a network protocol. The first device can determine that the second device failed to receive the first packet via the first optical transmission. The first device can transmit, responsive to failure of the first optical transmission, a second optical transmission at a second output level different than the first output level. The second optical transmission can include a second packet corresponding to the network protocol. The first device can identify that the second packet was successfully received by the second link manager agent. The first device can establish, responsive to the identification that the second packet was successfully received, the second output level as a transmission output level for the first device.
