Warnings (to be read before the TILx – HL installation)
Dealing with optical output ports
• The TDTX modules (both on master and on slave side) contain
semiconductor lasers. Invisible laser beams may be emitted from the
optical output ports. Do not look towards the optical ports while equipment
is switched on.
Handling optical connections
• When inserting an optical connector, take care to handle it so smoothly
that the optical fibre is not damaged. Optical fibres have to be single-mode
(SM) 9.5/125µm.
• Typically, Britecell Plus equipment is provided with SC-APC optical
connectors. Inserting any other connector will result in severe damages.
• Do not force or stretch the fibre pigtail with radius of curvature less than 5
cm.
• Remove adapter caps only just before making connections. Do not leave
SC-APC 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 with a proper tissue before inserting
each connector into the sleeve. In case adapter tips need to be better
cleaned, use pure ethyl alcohol
Inserting or removing TDTX, TMRX, TSRX modules
• Do not remove or insert any module into TPRN sub-rack before having
switched off main power supply.
• Modules must be handled with care, in order to avoid damage to
electrostatic sensitive devices.
• When installing the 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).
Placing the TILx -HL modules inside the subrack
• The i-link modules at slave side should be installed in the middle of the
slave subrack, or at least they should have no more than 4 TFLN modules
both on the right side and on the left side of the TSRX
2xx/8 module. This
requirement is advised in order to allow connection between the TSRX
module and all the TFLN transmitters (see fig. 5.33)
TILx – HL installation
Both on master side and on slave side, the i-link modules are to be housed
into a TPRN active sub-rack.
