Optronic data stream

A optronic data stream was a sequentially ordered finite set of information to components that use optics (light), such as holographic subroutine.

In 2374 Seven of Nine found an Hirogen subspace relay network that had the ability to send a message to a Starfleet ship detected in the Alpha Quadrant. B'Elanna Torres informed her that it might be possible to send a optronic data stream containing the holographic subroutine of The Doctor's matrix attached with a Starfleet signature.
