1. A receiver, suitable for use in a communication assembly configured to operate underwater, the receiver comprising,
at least first one or more photodetectors and second one or more photodetectors, wherein the first one or more photodetectors define a first detection area which can receive light, and the second one or more photodetectors define a second detection area which can receive light;
at least a first multiplexer which is configurable to selectively electrically connect any of the first one or more photodetectors or second one or more photodetectors to a signal detector module;
a controller which is connected to said least a first multiplexer so that the controller can selectively configure the first multiplexer to electrically connect any of the first one or more photodetectors or second one or more photodetectors to the signal detector module;
wherein, the controller is configured to,
configure the first multiplexer to electrically connect the first one or more photodetectors to the signal detector module; and wherein the signal detector module is configured to then determine a first quality factor which is representative of the quality of a signal output from the first one or more photodetectors to the signal detector module; and
configure the first multiplexer to electrically connect the second one or more photodetectors to the signal detector module; and wherein the signal detector module is configured to then determine a second quality factor which is representative of the quality of a signal output from the second one or more photodetectors to the signal detector module; and
compare the first quality factor and second quality factor to determine which signal output is better quality; and
configure the first multiplexer so that the first multiplexer electrically connects whichever of the first one or more photodetectors or second one or more photodetectors provides said better quality signal output to the signal detector module.
