5.1.13 Finishing the termination
Close the inner frame to its normal position and fix it with the lock that is on the bottom of
•
the frame.
Check still that the fibre tubes run from splice trays to the back of the frame in a well
•
managed way and are not subject to pressure, sharp bendings or any other risks.
5.2 Termination of cables when outdoor cables are spliced to pigtail cables outside the NC-1000
frame
Outdoor cables can be spliced to pigtail cables outside of the NC-1000 frame in a splice cabinet or joint
closure that can be inside or outside of the building. If the splices are outdoor , the pigtail cables have to be
brought to these splice points in duct pipes, not directly in the ground because the construction of the pigtail
cables does not withstand the direct installation in the ground.
In this chapter it is handled more exactly only the points that differ from the working steps described in the
chapter 4.1.
5.2.1 Bringing the outdoor cables to the splicing point
Bring the outdoor cables to the point (frame, rack, cabinet or closure) where the splicing will be made.
•
Measure the stripping lengths of the cables and cut away the extra lengths. Note that the fibre lengths
•
on the splice trays shall be at least 110 cm. If using Nestor NC-48 splice tray the fibre lengths shall be
about 120 cm.
Prepare the cables for splicing as described in the chapter 4.1.3.
•
Fasten and earth the cables.
•
Bring the fibres to the splice trays as described in the chapter 4.1.4. In the following picture fibres of the
•
outdoor cable have been brought to Nestor NC-48 splice tray.
Make the appropriate markings on the splice tray.
•
Place the splice trays to their positions for waiting the splicing process.
•
5.2.2 Installation of the NC-1000 patch panel
Release the locking of the inner frame from its bottom and turn it out as much as it goes.
•
If the pigtail lengths are not long (less than 25 m) you can do directly the working steps as described in
•
the chapter 4.1.6.
Note. If the pigtail cables are long or rather long (over 15 m) they are quite troublesome to straigthen or
•
handle near the frame and especially in the case of many pigtail cables. In these cases the installation
of the panels can be made on the alternative way as follows:
Loosen the loops of the pigtail cables near the panels about 2 m.
○
Take the cable loops one by one under the lowest fixing plate to the back side of the frame and
○
bring the panel through the inner frame to the front side of the frame.
Lift the panel near its right position to the front of the inner frame and at the same time lift the panel
○
frame to its position and fasten it to the frame from its lower fixing holes.
Push the panel to its position and lock it with two finger screws.
