In the package following items are included:
1 Patch panel with front
4 cagenuts with screws
4 bolts of different length for fixation of 1 to 4 splicetrays
3 loop rings
All other products must be purchased seperatly, the product numbers are mentioned where needed.

Leave some extra cable ( 5m)at different places on the cablelink. This makes it easier torepair in case of a brokencable.A minimum of 5 meters OFcable should be foreseen in thecabinet as this will facilitate thetermination of the cable in theOF patchpanel. Preferably do
the termination of the OF in thepatch panel on a table beforescrewing the patch panel intothe frame.Always cut the first meter ofcable as this part can bedamaged after pulling thecable, bending, waterdamage...More specific installationguidelines on indoor opticalfibre cable can be obtained
from our Optical Fibre IndoorCable IN STALLATION GUIDEwhich is available from ourNCS website.

Press the loop rings in the
foreseen holes. They will be used
later to support the fibres.
The advantage of the Snap-in
patchpanel is the flexibility to
accept different types of couplers
and connectors. Four versions
can be installed by using the
LAN mark snap-in couplers.
These couplers must bepurchased seperatly.
Available couplers are: DSC,
SC, 2LC and MT-RJ
Please be aware that patchcords
with a DSC connector are not
compatible with two separate SC
couplers. The orientation of the
key member is different.
Please consult the list below.

Snap the couplers into the Patch Panel by hooking
the top of the coupler under the front mounting
plate and then lowering the connector into its
aperture.
! Make sure to keep all protective caps on the
couplers during installation to avoid ingress of dust.
To remove the coupler: put a small screwdriver
under the connector in the opening to unlock.
Optional blank fillers (N420.655) can be installed
where no couplers are inserted.

Phase 3 Fibre termination
Phase 3A Direct connectorisation
Two termination practices are supported depending the used construction of your fibre cable.
In case of loose tube construction we advice to fusion splice to pigtails using a splice tray for protection. Due
to the fragile nature of the 250m fibre we advice not to use direct connectorisation a special microtube
(N890.045) must be used to protect the fibre when direct termination is chosen.
In case of tight buffer constructions both fusion splicing with pigtails and connectorisation are possible.
Following table may help you choose the preferred method.
Remove 2 meters of the outer sheath andthe aramid/ glass yarns from the cable.
Consult specific guidelines on removing
the outer jacket depending the
construction.
Avoid damaging the fibres while cutting
the outer jacket and yarns.
For 250 fibres the tube must be
removed leaving at least two loops in the
loop rings. Make sure to clean the fibres
with De-Solv-It to remove the gel.

You can either use an optional
cable gland (PG-16) or the
square opening using tie wraps
on the back to bring in the fibre
cable. Fix a permanent label on
the fibre cable for future
identification.
Provide at least two spare loops
in the patch panel and put the
fibres in the loop rings.Measure the length of each
fibre to the coupler respecting
both bending radius and the
color order and cut the rest of
the fibre.
Take the fibre out of the loop
rings and mount the connectors
on the fibre. W hen mounting
connectors on 250 fibre you
will need to use an optional
microtube (N890.045) to
reduce risk of damaging the
fibre. It is advisable to label the
fibres for easy identification.
Remove the dust protection caps
on one side of the couplers
where connectors will be
inserted.
A quick cleanness check of the
couplers may be advisable.
Compressed air or alcohol can
be used to clean the couplers if
there is ingress of dust. Loop thefibres back in the loop rings
and insert while respecting the
colour coding the mounted
connectors in the couplers.
The Recommendations to
maintain duplex OF channel
polarity technical paper, which
is available from our NCS
website, should be considered
when choosing the colour order.

In case of tight buffer fibre:
Un-strip the fibre cable to a
length of at least 1.6 meters to
allow enough spare fibre for
later maintenance purposes.
Consult specific guidelines on
removing the outer jacket
depending the construction.
Avoid damage to the fibres
while cutting the outer jacket andyarns.
In case of loose tube fibre:
Remove 1.6 meters of outer
sheath from the tube(s).
Use the correct tools in order not
to damage the fibres while
cutting the tube. Attach the outer
coating of the cable onto the
base at the back of the patch
panel by means of tie-wraps.
Tighten the tie wraps firmly.
If no tie wraps are used, then an
optional cable gland (PG-16)
has to be used to affix the cable
to the patch panel.
Fix a permanent label on the
fibre cable for future
identification.
Up to 4 splice trays may be
installed to hold up to 48 fibre
splices. Splice trays for fibre
splice protections are available
in metallic or heat-shrink
versions. It is advisable to install
a maximum of 12 splice
protections per tray. In specific
cases up to 24 metallic protected
splices can be installed. Fix the
first splicetray central in the
patchpanel with a bolt.

Remove the tube from the fibre toallow fixation in the splicetray (A) by
means of tie wraps. Clean the fibreswith De-Solv-it to remove the gel.Make sure to have at least two loopsof loose fibres in the splicetray. Up totwelve fibres can be installed perheat shrink splicetray and up to 24splices can be installed using metallicalu protections.Remove the dustcaps from thecouplers on the inside of the PatchPanel. A quick cleanness check ofthe couplers may be advisable.Compressed air or alcohol can be
used to clean the couplers if there isingress of dust. Insert the connectorsof the pigtails in the couplers.Measure the length of the 900buffer needed to fix the pigtail in thecomb (B) of the splicetray keeping inmind the bending radius. Make sureto use the comb on the side of theconnectors you have just installed.The fibres from the pigtails shouldmake two loops in the oppositedirection. Our Maxi strip pigtails
allow to remove the 900 buffer inone go after being cut at the rightlength.Minimum two loops of fibres from thepigtails in the splicetray is advised.In case of using a fibre cable withmore than 12 250m fibresseparation of extra fibres is needed.This can be done by using 20 cm (C)of empty tube for splicetraysN890.145 to link both splice trayson the opposite side of the pigtails.The top-right comb of the secondsplice tray must be removed in orderto accept the tube with the fibres.Cut the first 12 fibres to the rightlength and joint them by fusionsplicing with pigtails respecting thecolour sequence.
The Recommendations to maintainduplex OF channel polaritytechnical paper, which is availablefrom our NCS website, should beconsidered when choosing the colour
order.

Protect the splices with a metallic
N890.003 or a heat shrink
splice protector N890.021.
Fixate the splice protector into
the correct splicetray at the
designated place and gently
loop the fibres back in the splice
tray.
For splicetray with metallic splice
protection use N890.010
For splicetray with heat shrinkprotection use N890.020
For splicetray cover use
N890.022
After installation of the first
splicetray you may insert the
other fibres from the same cable
in the empty tube and fix the
tube to the second splicetray.
You may repeat the same phase
to add the third and fourth
splicetray where the pigtails are
installed on the other side.

The Patch Panel can now be
gently closed and installed in
the cabinet. Screw the patch
panel in the frame.
Loop the fibre cable in the back
of the cabinet respecting
minimum bending radius of the
cable.Add the front cover after
installation in the cabinet.
Label the ports conform the
company policy.
The Patch panel is now
installed.
Use a 2 HU patchguide to
neathly install all patchcords
maintaining the bending radius.
Push back the tray after
installing all the patchcables.
This in order to protect the
connections.
