Tip: Do not click the 2 simplex plugs closed individually, click them closed together so
that they a complete a "duplex plug". In this manner you will achieve a better hold in the
plug adapter.
IMPORTANT: The smoothed and polished surface of the plastic fibers must be absolutely
flat and even. Likewise, the plastic jacket must not protrude or be cut unevenly. Every
irregularity causes strong attenuation of the light signal via the fiber-optic cable!
