of these containers must be maximum guarantee the physical safety
of the fibers during handling as well as easy access to the splices.
19.3 Recommendation ITU-T
19.3.1 Splice protection systems must meet the requirements of the
Manual of ITU-T "CIRP / FO" latest edition.
19.3.2
Nature of splice protection systems: Splice protection
systems should preferably be made of fiberglass or other alloy
which increases their mechanical strength according to the latest
recommendations of the ITU-T and Series corresponding ISO
9000.
19.3.3 The Manufacturer will describe the mechanics and technical
design of the proposed splice protection systems.
19.3.4 The connection methods of fiber optic cables described in
Chapter III of the manual (CIRP / FO) of the ITU-T must be

considered.
Capacity protection systems splices - The Manufacturer must comply
with the following specifications:
19.4.1 Connecting the boxes must allow the junction of at least two
independent optical fiber cables.
19.4.2
Junction boxes should allow the junction of four
independent optical fiber cables.
19.4.3 Splice protection systems must be equipped with the
arrangement of fiber optic systems.
19.4.5 Junction boxes must accommodate the total number of fibers
with lengths between 1.5 and 2 meters for interventions. The
curvature of the fibers inside the boxes must be greater than
thirty (30) millimeters.
19.4.6 Cassettes must be equipped with appropriate housing for both
types of splices (mechanical and bow).

mechanical
20.1
Factors to be considered for closure fittings are those described in
the most recent manual "CIRP / FO" ITU-T (Chapter V, paragraph 2. Page
84).
20.2 The permissible limits of use of the proposed splice protection systems
must be specified by the manufacturer. The testing method of these
parameters must be specified and submitted for approval.
20.2
Splicing box
Due to its location in drawing room, this box should have high protection
features:
shock resistance 20 joules (IK 10 according to EN 50102)
protection against the effects of immersion (IP 68 to EN 60529)
temperature range from - 30 ° to + 70 °,
tensile strength of 100 daN by mechanical attachment of the cable
to the box.
These criteria will be achieved by:




a pressurizing continuously to 100 mbar,
a sealing body by elastomeric seal,
a sealing entries by heat shrink and / or resin, or mechanical
clamping on joint.
Furthermore this box will have the following options:



Opens and closes without removal,
sufficient number of entries (minimum 4) for all architectures,
inputs and fasteners allowing a cable to optical fibers of diameter
25 mm,

inputs for reoperation or passage in cable to any input,

inputs providing mechanical retention of the cable upstream and
downstream of the stuffing box,

versatile mooring systems for different types of cables,

clamping sole plates for fixing all the mechanical elements of the



fiber optic cable to the housing,

elastomeric sealing gasket compressed between body and cover
with stainless steel screws,

pressurizing using the helium valve 0.5 bar (for maintenance and
support for localization)

fixing suspension of the box on the solder side panel road to pull
chamber,

placing the earth potential by terminals accessible from the
outside.
The inputs of fiber optic cables will be used interchangeably on arrival
and departure of fiber optic cables to allow a reserve coiling without any
constraint inside the drawing rooms. In case of mechanical failure, the
entries, the body or the cover should be able to be replaced without a cut
optical connections being necessary.
These boxes will:

the single junction or derivation,
wiring passage (uncut coiled tubes and left waiting in each cassette
respecting the color code of the ITU-T standard).

The interior of the box will include a storage space for the passage
tubes. Management of bare fiber excess length and the protection and
storage of splices will be provided by a cassette organizer, on a one
cassette tube. These cassettes articulated on a chassis possess a
translucent cover protecting and visualization of fibers. In addition, they
may be returned (cover up or cover downwards) to allow work in any
position (intervention flattening box or vertically).
The tape will be a protection module and splice for a minimum capacity
of 12 fibers.
Studied the size of the tape will ensure the minimum bend radius of the
fibers. Its interior will also lover of crossing fibers (uncut fibers).
21.1The splice protection system must be waterproof.
21.2 It should have a resistance against the atmospheric temperature variation
