3.1 Connecting optical bus lines
Use a duplex fiber-optic cable with BFOC/2.5 (ST
connectors to connect the individual repeaters.
Pay attention to the maximum cable length of the
fiber-optic cables as well as the possible types of
fibers specified in the Technical Data.
Make sure that each optical input a is connected to
an optical output J at the opposite end ("cross-over
connection").
The corresponding BFOC sockets of the two ports are
marked on the lower front panel.
Ensure that sufficient strain relief is provided for the
fiber-optic cables and pay attention to their minimum
bending radii.
Unused BFOC sockets must be sealed with the sup-
plied protective caps. Incident ambient light and, in
particular, excessively high ambient brightness can
affect the network.
The penetration of dust may impair operation of the
optical components.
