1. In a sealed fitting extending through a structural member separating a high pressure medium from a lower pressure medium, an improvement for ensuring the optical transmission of data therethrough is provided comprising:

  • first optical means connected to one end of said fitting for transferring optical signals representative of data between the high pressure medium and said fitting;

    second optical means connected to the other end of said fitting for transferring said optical signals between said lower pressure medium and said fitting;

    means for defining a coaxial bore in said fitting reaching from the first traNsferring means to the second transferring means;

    means disposed in said coaxial bore for optically coupling said optical signals between said first transferring means and said second transferring means; and

    a coating of an epoxy adhesive interposed between the coupling means and said coaxial bore and extending the full length of the coupling means for securing and for sealing the coupling means in said coaxial bore to ensure the passive guidance of said optical signals while maintaining the watertight integrity of said fitting.
