1 Introduction

The generic closure FIST-GCO is the environmentally sealed enclosure for the fiber management system that

provides the functions of splicing and passive component integration in the external network. The product can

be tailored to almost any required configuration by adding splicing and/or passive device Sub-Assemblies. The

FIST-GCO has provision for all cable termination and sealing requirements.

To clean FIST components, the use of isopropylalcohol is recommended.

The closure is a single-ended design made of a thermoplastic material.

The base and dome are sealed with a clamp and an O-ring system. One oval entry port for looped (uncut) cable

management and six or sixteen round ports for single cable entry/exit are included in the base. The cable seals

are manufactured from heat-shrinkable material. The Universal Mounting System provides the foundation for

mounting SOSAs and SASAs back to back. The two back to back sides have each a standard capacity of

28, 42 or 58 units. Uncut loose buffer tube storage is available between the two UMS-sides (Universal Mounting

System). Storage of uncut looped ribbons or fibers from central core (or slotted core) cables is available with the

fiber storage basket. Storage of uncut looped ribbons or fibers can be done in individual FIST-trays.

4.1 Loose buffer tube cable

4.1a Looped cable preparation

4.1.1. S-cable: A window cut of 3m50 is needed for GCO2-BC6-XX,

3m70 for GCO2-BD6-XX and 3m90 for GCO2-BE6-XX.

4.1.2 S-cable: Mark the cable in the middle and mark the cable on

(1.75), (1.85) or (1.95) meters left and right of the first mark. Remove

the cable jacket starting in the middle.

3.2.1 Open and remove the clamp. Remove the dome and the O-ring

Remark: take care with the O-ring and the sealing surfaces on the base

and dome (avoid damaging). Clean only with clear water or with the

cleaning tissue, included in the kit, if needed

4.1.3 Reversed Oscillating cable: Mark the cable in the middle of the

loop and remove cable jacket left and right of the mark over a total

distance of 110cm (little more as the distance between two reversal

points on the cable). Locate the buffer tube reversal point on the cable

and mark the cable on (1.75), (1.85) or (1.95) meters left and right

from this point. Remove further the cable jacket starting from this

point.

Important: make sure that twist position of loose tube is identical in A

and B. This must be done correctly for ease of installation.

4.1.4 Remove the strength member leaving 80mm from the cable

jacket, if shield present leave 15mm of the shield

4.1.5 Clean the loose tubes, remove all grease.

4.1.6 Identify the loose tubes with the split collet rings markers if

necessary. There are different FIST-split-collet-rings depending on

diameter of the loose tube.

4.1.9 Open the oval port; the cutting wire can be used.

4.1.8 If the cable diameter is more than 8mm Fix the cables with the

hose clamp onto the loop bracket. Wrap a few layers of tape around

the hose clamp.

If the cable diameter is less than 8mm fix the cables with tie wraps.

• When using cables with a diameter smaller than 12mm,bend the

sharp edges on the bottom of the bracket towards the cable and use

some tape around the bracket to protect the heatshrink.

4.1.10 Take the oval sleeve and place the packing bag that has been

opened on both sides in the oval sleeve to prevent the hotmelt inside

the sleeve from dirt and grease. Take the LCIT and bend the loose

tubes gently over it. Push the loose tubes in the sleeve. The non-coated

edge of the sleeve and the arrows should be pointed to the base of the

closure.

4.1.11 Now push the loose tubes (looped around the LCIT) in the oval

port up to the bottom of the bottom bracket.

4.1.12 Remove the LCIT and pull the cable gently in the closure.

4.1.13 Position the loop bracket in the bottom bracket and lock with

the split pin.

4.1.14 Install heatshrink.

4.1c Loose buffer tube storage

4.1d Fiber storage in trays

4.1.15 Select the loose tube(s) with the fibers that have to be spliced.

4.1.15 Make some loops with the uncut loose tubes, and put these in

the plastic bag (Be careful not to damage the loose tubes!).Two sizes of

bags are available. Use the correct size according the volume of the

loose tubes.

Slide the bag between the UMS. If the capacity of the looped loose

tubes is too much, one puts the loops at one side; in this case fix the

plastic bag with the tubes on the UMS-profiles with tie-wraps. In case

of S-cable cut the loose tube(s) in the middle of the loop for routing

them to the tube holder.

Remark: Loose tubes routed up to the tube holder should be

routed in such a way that one still has complete access of the

stored tubes between UMS profile. This is needed for later

routing of loose tubes from the loops to the tube holders,

without creating crossings and without creating disturbances

on the loose tubes already routed up to the tube holders.

4.1.16 In case of reversed oscillating cable: separate the loose tube(s).

Match the loose tube(s) on the tubeholder and mark both sides

between the two marks. Shave between the two marks with the

appropriate tooling. Clean the fibers and wind some Teflon around the

ends of the tubes and fibers ,to protect the transition from tube to

fibers.

In case of S-cable: cut the loose tube(s) (with fibers that have to be

spliced) in the middle of the loop. Separate the cut loose tube(s) from

the others. Match the loose tube(s) on the tubeholder and mark both

sides. Strip the loose tube(s). Clean the fibers.

- Separate the fibers till the tubeholder and route to single circuit or

single element tray(s).

4.1.18 In case of Reversed oscillating cable Identify exchange and

customer-side using some Teflon tape around the fibers. One can also

use the FIST-split-collets-rings markers to identify the loose tubes.

4.1.17 Different loops can be put together beneath the same tube

holder retainer. Position one or more loose tubes in the tubeholder and

slide the tube holder retainer with the snap forward in the lowest

possible cavities of the tubeholder above the loose tube(s). The tube

holder retainer must snap.

4.1.19 - If the fibers are ‘twist free’ one can route the fibers separate

to single circuit trays or single element trays. Separate all fiber loops

first till the tubeholder.

If the fibers are not ‘twist free’ select first the fiber(s) that have to be

spliced and cut these fibers in the middle of the loop. Remove these out

of the bundle till the tubeholder. These fibers can be routed to single

circuit trays, others uncut will be routed to a single element tray (never

in dark fiber storage) (See at fiber routing).

4.1.22 Remove the strength member leaving 90mm from the cable

jacket, if shield present leave 15mm of the shield.

4.1.23 Fix the strength member connector in the closure (on the

bottom bracket )

4.1.24 Take the sleeve and place the packing bag that has been

opened on both sides in the sleeve to prevent the hot melt inside the

sleeve from dirt and grease.. Push the loose tubes in the sleeves. The

non-coated edge of the sleeve and the arrows should be pointed to the

base of the closure (see installation heatshrink).

4.1e Drop cable preparation (6 port base)

4.1.20 Open the round port; the cutting wire can be used

4.1.21 Remove the cable jacket for 2.2m.

8

4.1.28 Fix the strength member connector in the closure.

4.1.27 If ports 3-4-5-6-7-8-9-10 are used, cut strength member at 75

mm length. If ports 11-12-13-14-15-16-17 and 18 are used, cut

strength member at 90mm length.

4.1.25 Push the loose tubes in the port and fix the strength member in

the strength member connector. Be sure that all loose tubes are routed

without crossing around the strength member.

4.1f Drop cable preparation (16 port base)

4.1.26 Remove the cable jacket for 2.2m.

4.1.29 Fix the cable in it.

4.1.30 Install the heat shrink.
