The Installation of a fibre Patch Panel must be carried out with care and precision. Make shure to work on aclean and level worksurface.

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.

Remove the front plate and slidethe Patch Panel open.

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.

Phase 2 Choosing connector types


7/13


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.

Continue with Phase 4


10/13


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.
