1. General

In optical distribution frames (ODFs) optical bre cables are terminated and connected to other cables and

equipment. The number of cables coming to and leaving from an ODF may be very high depending on the

type and purpose of the ODF. Therefore it is very important that the ODF including all cable installations has

been designed, planned and installed with appropriate skill and knowledge.

NC-1000 bre optic cross-connection system is an ODF that is designed according to the most critical

requirements to reach a solution with easy installation, good functionality and high reliability. All important

aspects are taken into account regarding cable assembly, bre connections as well as addition of new

cables and modications. Modular and clear design, usage of pre-assembled patch panels and smart bre

management provide easy installation, changes, expansions and other maintenance practices during the

entire lifetime of the system.

3. Mounting of the frame

NC-1000 frames are delivered separately protected with their own transportation pallet. In the

installation site the frame is shifted to its place and fastened to the oor. Before fastening the

frame shall be adjusted directly from its adjusting feets. If necessary, the frame can be also

fastened to the wall from the top with an optional wall mounting kit.

4. Earthing of the frame

If outdoor cables including metallic elements are brought to the frame, the frame shall earthed.

Make the earthing by connecting the frame to the equipotential or earthing terminal of the

equipment room by using min. 16 mm2 copper wire. Adjust the earthing bar of the frame to the

suitable height and connect the copper wire to the bar.

5. Termination of outdoor cables to NC-1000 frame

There are two principle ways of outdoor cable termination:

Outdoor cables are jointed to pigtail cables within the NC-1000 frame.1.

Outdoor cables are jointed to pigtail cables outside the NC-1000 frame within a joint closure or a splice2.

cabinet.

These termination methods are handled separately in the following chapters.

5.1 Termination of outdoor cables to pigtail cables within the NC-1000 frame

5.1.1 Installation of the splice tray holder

Take the splice tray holder with its mounting accessories from its package and turn it in the right way for•

mounting to the inner frame.

Install the basket nuts of the splice tray holder to the followig mounting places of the inner frame:•

upper nuts: 43 cm from the bottom of the inner fame

lower nuts: 23 cm from the bottom of the inner fame

Fix the splice tray holder with its screws to the inner frame.•

5.1.2 Bringing cable to the frame

Either the top entry or the bottom entry can be used. Cables are brought to the frame outside

of the back side where they are earthed if necessary and from where the bres are brought to

the inner frame and to the splice trays in their protection tubes.

It is worth of noting that the cables are not xed permanently to the frame until they have been

spliced.

Cables are brought to the frame as follows:

Release the locking of the inner frame from its bottom and turn it out as much as it goes.•

Draw the cable ends through the frame below its lowes xing plate. •

Draw the cable ends enough out from the frame over their stripping lenght. The stripping•

length is about 250 cm.

Measure about 250 cm stripping lengths of the cables starting from the sheath removal •

points and cut away the extra lenghts.

5.1.3 Preparation and earthing of cables

Remove the cable sheaths starting from the sheath removal marks.•

Prepare and earth the cables according to the instructions of the cable supplier.•

Two examples are described in the chapters 4.1.3.1 and 4.1.3.2. It should be noted that•

these are only examples. In every case the instructions of the cable supplier shall be

carefully followed.

5.1.3.1 Stranded loose tube cables

Cut the cable sheath from the sheath removal point marked before.•

Remove the cable sheath about 10 cm from the cable end and nd the rip cords.•

Split the cable sheath with rip cords to the sheath removal point and about 30 mm over it.•

Cut the parts of the cable sheath from the sheath removal point.•

Remove all protective layers over the bre tubes.•

Separate the bre tubes and the possible llers from each other.•

Cut the central element and the possible llers at the point where the sheath has been cut. Note, if the •

cable has metallic central element cut it to the length of about 20 cm.

Straighten the bre tubes by using a hot air blower or hot water. If you use a hot air blower, be careful •

that the bre tubes dont’t get too hot.

Connect the connector of the earthing conductor to the possible aluminium laminate or corrugated steel•

tape. Protect the connection point with an insulating tape.

5.1.3.2 Central loose tube cable

Expose the strength elements on both sides of the cable and turn them up to the sheath removal point•

marked before. Cut them to the length of about 20 cm and bend them on both sides.

In the case of a cable with aluminium laminate or corrugated steel tape remove the sheath and other•

protective layers up o the distance of 50 mm from the sheath removal point. Remove the cable sheath

in several parts.

In the case of non-metallic cable remove the sheath and protective layers up to the sheath removal•

point. Remove the sheath in several parts.

Remove the sheath from the possible aluminium laminate or corrugated steel tape with a hot air blower•

and pliers.

Use e.g. a steel brush or a knife to remove also the possible plastic coating from the laminate or steel•

tape in order to ensure the electrical contact for earthing.

In the case of metallic strength elemens turn them to the same side of the cable and then at the•

distance of about 30 mm from the cable towards the cable end. Try to get them as straigth as possible

and also near each other that they can be easily guided to the earthing connector. Cut them to the

same length as the aluminium laminate or corrugated steel tape.

Cut the central tube at the distance of 30 mm from the aluminium laminate or steel tape and in a case of•

non-metallic cable at the distance of 30 mm from the cable sheath. Cut the central tube by making rst

a scratch around the tube and then bending the tube carefully at the both sides until it breaks.

Take a hold from the bres with ngers and pull the central tube away.•

Clean the bres from the lling compound.•

Push the fan-out part of the installation kit (accessory) over the central tube and at the•

same time guide the bre bundles along their own slots of the fan-out part.

Fasten the fan-out part with the clamp to the end of the central tube. If the fastening is not•

tight, use the small adjusting parts of the kit under the clamp.

Draw the bundled bres into the protection tubes of the installation kit by using the pulling •

wire included the kit. The minimum length of the tubes is 110 cm.

Push the protection tubes to the slots of the fan-out part and guide the bres at the same •

time directly from the central tube to the protection tubes.

Mark the ends of the protection tubes with numbers 1,2,…•

5.1.4 Fibre entry to the splice tray

Remove the cover of the splice tray•

Measure the bre lenghts to the splice tray. If using Nestor NC-48 splice tray the bre •

lengths shall be about 120 cm.

Bring the ends of the bre tubes to the left side of the splice tray (seen from the top) and •

put them parallel so that the outermost tube is the rst and innermost tube the last tube.

Fix the tubes with nylon ties.•

If you are terminating stranded loose tube cable cut the tubes about 25 mm from the xing •

point and clean the tubes from the lling compound.

Loop the bres to the splice tray. Loop each bre bundle one full turn on the tray and take •

each bre bundle to its own splice holder from the left side Cut away the extra lengths of

bres.

If you are using Nestor NC-48 splice tray, loop the bres going to the two uppermost splice holders one •

full turn around the tray and then to their splice holders from the left. The bres going to two lowest

splice holders loop bres rst to other side of the tray from the halfway of the tray, then one full turn

around the tray and nally to their own splice holders from the right, see the picture below.

Make the appropriate markings on the splice tray. •

Reattach the cover to the splice tray.•

5.1.5 Installation of the splice trays to the splice tray holder

Draw the cable backwards to the back side of the frame so much that the cable sheath is outside of the•

frame.

Fix the cable temporarily to the frame.•

Install the splice tray into its appropriate position for waiting the splicing process.•

Guide the bre tubes below the splice trays on the hinge side of the inner frame to the back of the •

frame.

The bre tubes shall be positioned considering the following:•

Bending radius of bres○

Movement of the inner frame○

Possibility to remove each splice tray separately from the splice tray holder○

5.1.6 Installation of NC-1000 patch panel

Open the panel package and lift the panel out from the package with its pigtail cable.•

Take the basket nuts from the accessory kit and mount them to the right places of the inner frame.•

Install the rst panel of the frame into the highest place of the inner frame and the next panels under the •

earlier panels.

Pull the panel frame out from the panel and fasten it to the inner frame from its lowest xing holes.•

5.1.9 Preparing the pigtail cable for splicing

Remove the pigtail cable from the management hooks of the inner frame.•

Cut the sheath at the point of the cutting mark.•

Remove the sheath at the length of about 10 cm from the cable end and nd the rip cord.•

Split the cable sheath by using the rip cord and remove the sheath.•

Cut all the binding yarns, tapes, llers and the central element at the point where the cable sheath was •

cut.

Fasten the end of the cable sheath with nylon ties to the side of the splice tray which is opposite to the•

side where the bre tubes of the outdoor cable are fastened.

Cut the bre tubes at the distance of about 10 cm from the point where the sheath was cut and clean •

the bres from the lling compound.

Note. Try rst the stripping of the bre tubes before the actual work to make sure that you have a ○

suitable stripping tool and the tool has the right adjustments. A wrong tool or a wrong adjustments

of the tool can cause damages or even cut the bres.

5.1.7 Bringing of pigtail cables for splicing

Bring the pigtail cable to its splice tray loosely below the splice tray and from the front side•

(seen from the front).

Make a cutting marks on the cable to such lengths that the sheath length on the splice tray •

is about 30 mm and the bre length is at least 110 cm. If using Nestor NC-48 splice tray

the bre lengths shall be about 120 cm.

Cut away the extra length from the pigtail cable.•

Remove the splice tray from the splice tray holder and set it on the splicing table.•

Loop the bres on the splice tray. Loop each bre bundle one full turn on the tray and take •

each bre bundle to its own splice holder from the right side. Cut away the extra lengths of

bres.

If you are using Nestor NC-48 splice tray, loop the bres going to the two uppermost splice •

holders one full turn around the tray and then to their splice holders from the right. The

bres going to two lowest splice holders loop rst to other side of the tray from the halfway

of the tray, then one full turn around the tray and nally to their own splice holders from the

left, see the picture below.

In the following picture the bres have been prepared for splicing by using an alternative •

splice tray LT-48.

5.1.10 Splicing of bres

Take the bre bundles out from the splice holders and place them on both sides of the splice tray in •

their order.

Splice the bres of the outdoor cable to the bres of the pigtail cables bundle by bundle with a fusion •

splicer.

Loop the spliced bres on the splice tray and place the bre protection sleeves to the holders according •

to the bre order. Take care in looping the bres that you don’t leave the bres under their minimum

bending radius (min. 40 mm).

When all the bres have been spliced check still that the installation of all the bres on splice tray has •

been made properly. In the following pictures there are examples of the splice trays after all bres have

been spliced.

Fasten the cover of the splice tray.•

Mount the splice tray into its position in the splice tray holder.•

5.1.11 Fastening and earthing of cables

Place the outdoor cables after splicing in the backside of the frame to their right positions and fasten•

them to the xing plates with nylon ties. The fastening and positioning should take into account the

possibility of adding new cables in the future.

Connect the metallic elements of the cables to the earthing bar of the frame.•

5.1.12 Fastening of the bre tubes

Guide and manage the bre tubes leaving the splice trays from the hinge side of the inner frame to the •

back of the frame.

Loop and bundle the bre tubes and fasten the bundles to the xing plates in the back of the frame. •

As fastening the tubes note the movement of the inner frame. E.g do not fasten the tubes to the lowest•

xing plate because at this place the tubes shall have a possibility for slight movements.

If necessary the bre tubes at the back side of the frame can be protected with e.g. a spiral type •

protection tube.
