FS-S038-2IO-24F 24 Dome Fiber Optical Splice

Introduction

Thank you for choosing the dome ﬁber optical splice closure (FOSC) & ﬁber optical splice tray (FOST).
This guide is designed to familiarize you with the layout of the FOSC&FOST and describes how to deploy them in your network.

Accessories

Installation Requirements

To ensure the technical requirements, the following instructions must be followed:

Fibers with protective coat are ﬁxed with nylon tie at the entrance of FOST.
Grommet should be pressed from inside to outside in order to properly install FOST.
Straight-through and reserved ﬁbers with protective coat should be winded to the ﬁber holding tray.
The internal tighteners and ﬁxing nut of reinforced core must be well tightened.
Seal ﬁtting is installed neatly and smoothly.
The heat shrinkable ﬁxing sleeve must be reliable and sealed completely.

Installation

Open the Closure

Demount the hoop ﬁxing bolt and pull the hoop locking system out, then proceed in demounting the hoop. Pull the FOSC cover upwards out.

NOTE: If the weather condition is not good enough, then a tent must be pitched for waterproof and dustproof.

Determine the Length of the Fiber Cable

If all ﬁbers are for branch splicing, please refer to 2(A) for stripping length. If some ﬁbers are for straight-through, while others are for branch splicing, please refer to 2(B) for stripping length.

NOTE: 1. Reserve enough length of ﬁber cable to be spliced.
Stripping length also could be decided by customers according to installation requirements.

Strip oﬀ Fiber Protective Coat of Fiber Cable

Fiber-Optical-Splice-FIG-6

Strip oﬀ protective coat of ﬁber cable from the temp locating mark with the cutter and the stripper, please refer above drawing for stripping length. Stripping length also could be decided according to installation requirements.
NOTE: If it is diﬃcult to pull all the protective coats of ﬁber cable at one time, strip it oﬀ section by section to avoid ﬁber breakage.

Separate Fiber Cores

FIG-7

Wind 2 layers of insulation tape on a protective coat of ﬁber core for protection. Meanwhile, get rid of the stuﬃng to separate ﬁber core and clean them. Form a ring with a diameter of 100mm or so and ﬁx it on the ﬁber temporarily by adhesive tape.
Depending on ﬁber cable stripped, the following two cases are available：
All ﬁbers are to be branched after being spliced completely.
Some of the ﬁbers are for straight-through after being winded, while the others are for branch splicing.
The FOSC is provided with 3 single entry/exit tubes which suit for single ﬁber cables with max. diameter ф20mm and 1 mass entry/exit tube which suits for 1piece of ﬁber cable with max. diameter ф 20mm or 2 pieces of ﬁber cables with max. diameter ф 15mm or multi-pieces of ﬁber cables with short diameter.
Mass entry/exit tube is required if some ﬁbers are for straight-through.
The corresponding entry/exit tube cover could be slightly knocked out with screwdriver from inside to outside according to number and diameter of ﬁber cable required. 6.
Reserve reinforced core in 70mm length and cut oﬀ the unnecessary ones.

NOTE: Entry/exit tubes are to be selected accurately to make it easy for splicing and sealing.

Fix Reinforced Core & Pyrocondense, Fix and Seal ﬁber cable

FS-S038

Insert ﬁber cable into the corresponding heat shrinkable ﬁxing tube, further insert the them into entry/exit tube at the bottom of FOSC.
Demount ﬁxing nut of reinforced core with a special wrench (plastic one), which is to be inserted into the ﬁxing slot afterward and tighten it. Then re-tighten it with a metal wrench (the metal wrench is to be provided by operator).
Hitch heat shrinkable ﬁxing sleeve to the ﬁber cable till its root by hand.
Please refer to above drawing for installing branching clip.
Heat heat shrinkable ﬁxing sleeve with ﬁre sprayer to make it hugging entry/exit tube and ﬁber cable to reach complete sealing.

NOTE: 1. Fixing nut of reinforced core should be tightened.
While heating, heat shrinkable ﬁxing tube should shrink evenly, and there should be no bubbles, pores and other defects inside the tube.

Install Heat Shrinkable Protective Sleeve and House ﬁbers

FS-S038-2IO-
24F-24-Dome-Fiber-Optical-Splice-FIG-9

When having completed splicing the ﬁbers, the ﬁrst ﬁber ring should be housed on the farthest side of FOST, the remaining ﬁber optic should be winded, forming a ring with diameter not less than 80mm. then put it into FOST (Fiber Optic Splice Tray) together with heat shrinkable protective sleeve. (Firstly ﬁx heat shrinkable protective sleeve into the slot, then enlarge the diameter of ﬁber ring properly.)

NOTE: Pay attention to the twist and bend of ﬁber.

Assemble FOSC Housing and Fix FOSC

Put desiccant into FOSC.
Put FOSC cover on base directly.
Install plastic hoop between FOSC cover and base, tighten hoop locking system, which is to be ﬁxed by hoop ﬁxing bolt then.
FOSC installation:
Aerial application: ﬁx metal hoop and transom to the pole. Please refer to the above Drawing;
Wall mounting application: ﬁx the bracket on the wall with the bolt. (metal hoop is not required.)
Underground application: metal hoop is not required.
