4.4 Installation
4.4.1 Connecting the optical lines
Connect the individual modules using a dual-fiber optical fiber line
with BFOC/2.5 connectors.
Ensure
– that the end faces of the optical plugs are free of contamination.
– that respectively one optical input
a
and one optical output
J
are connected to one another (crossover connection).
The BFOC port sockets which belong to one other are marked on
the bottom of the front plate.
– that the optical plugs on the BFOC socket are securely attached
(bayonet fastener must be slotted in).
Ensure that there is sufficient strain relief on the optical fiber line,
and pay attention to the minimum bend radius.
Seal BFOC sockets which have not been assigned using the sup-
plied protective caps (note: an optical port which has not been
assigned should be switched to the operating mode ”Line without
optical fiber link monitoring“ to avoid a break in the fiber line from
being signaled).
Extraneous ambient light can cause interference in the network,
especially under very bright conditions. Optical components can
be rendered useless if dust infiltrates them.
Please note the maximum length of the optical fiber line and the
possible fiber types which are shown in Table 1, p. 6 and in the
Technical Data, p. 31.
