Page: 134 / 200

Note:
The optical components (transmitter and receiver) on a fiber optic link must be of the same
type.
Plastic optical fiber (POF) cables can be used with both 5 MBd and 10 MBd optical
components. 10 MBd components also enable the use of Hard Clad Silica (HCS®) cables,
which allow longer connection distances thanks to their lower attenuation. HCS® cables
cannot be used with 5 MBd optical components.
The maximum lengths of fiber optic links for POF and HCS® cables are 20 and 200 meters
respectively.
