Signal transmission using fiber optics (LWL)
As an alternative to conventional signal transmission
using copper cables, the signals from the incremental
encoders can also be transmitted through fiber optics.
The signals (0°, 90°, marker pulse, and LED check,
which are available in parallel, are encoded in the
transmitter and transmitted via just one fiber optics
cable to the decoder in the equipment cabinet.
The decoder converts the coded signals back into the
standard electrical signals with their complementary
inverted signals.
Advantages of fiber optics transmission
• High transmission capacity for long cables
• High transmission reliability
• Electrical isolation (encoder – decoder)
• EMC insensitivity
• LWL decoder with two outputs
• Low cable costs through transmission via
a single fiber optics cable
