Connections
Fibre optic connections (V1...14, also V21...36 with APBU-44CE)
WARNING! Handle the fibre optic cables with care. When unplugging optic cables,
always grab the connector, not the cable itself. Do not touch the ends of the fibres
with bare hands as the fibres are extremely sensitive to dirt. The minimum allowed
bend radius is 35 mm.
When connecting the fibre optic cables, make sure that receivers (RXD) are
connected to transmitters (TXD). Do not remove the protective rubber plugs from
unisued optical connectors.
