Optical fiber uses extremely thin
quartz glass which breaks easily
when nicked. If the length of the
cable is greater than required, coil
it at the rear of the unit, with a large
coil diameter (at least 10 cm). Do
not bend the cable sharply. Never
attempt to modify or shorten the
cable.
●
The signal travels through the core
of the optical fiber. Therefore,
damage to the plug tip or dust in
the connector housing can ad-
versely affect the transmission of
digital signals. When not in use, you
should always place the protective
cover on the connector.
●
When inserting or removing an op-
tical fiber cable, always grasp the
plug firmly. Never pull on the cable
itself.
COAXIAL DIO-OC1
