7.2 LASER OSCILLATOR CONNECTION USING AN OPTICAL
FIBER CABLE
When one of the following conditions is satisfied, an optical fiber
cable must be used to connect the laser oscillator to the I/O link:
(1) The length of the required cable is at least 10 m.
(2) A 5.5-mm
2
grounding line cannot be used to establish a
connection between the CNC control unit and the cabinet
housing the I/O unit etc., or a connection between the CNC
control unit and the laser oscillator.
(3) The cable may be susceptible to high-level noise.
For example, when the cable is placed near any machine which
produces high-level magnetic noise, such as a welder. Or, when
most of the cable runs parallel to a power line or power
magnetics cable.
(4) The laser oscillator to be connected is certified by the CE
marking system.
Optical I/O link adaptors
To use optical fiber cables for making connections, optical I/O link
adaptors must be used, as shown below.
