Handling optical connections
• When inserting an optical connector, take
care to handle it in order not to damage the
optical fi bre. Optical fi bres have to be single-
mode (SM) 9.5/125µm.
• Typically, ION-B equipment is provided with
SC-APC optical connectors. Inserting any
other connector will result in severe damages.
• Do not force or stretch the fi bre pigtail with a
radius of curvature less than 5 cm. See Fig. 19
for optimal fi bre cabling.
• Remove adapter caps only just before
making connections. Do not leave SC-APC
• Do not remove or insert any
TFLN module into TPRN sub-
rack before having switched
off main power supply.
• The TFLN modules must
be handled with care, in
order to avoid damage to
electrostatic sensitive devices.
• When installing TFLN modules
in the sub-rack, take care to
alternate active and passive
cards in order to ensure
proper heat dissipation.
• In a multi-sub-rack system,
remember to assign to each
sub-rack a proper RS485 bus
address before installing the
modules (please refer to TPRN
section for further details).
adapters open, as they attract dust. Unused SC-APC adapters must always be covered
with their caps.
• Do not touch the adapter tip. Clean it thoroughly before inserting each connector into
the sleeve. In case adapter tips need to be cleaned better, use pure ethyl alcohol
