The H14447 is a photosensor module containing a high-speed response 28-mm diameter head-on photomultiplier tube, and a high-voltage power supply circuit. Besides high-speed response, these modules feature high gain and have a large effective diameter for better light collection making them ideal for high-speed underwater optical communications.
