Enbeam Fibre Optic Splice Closure
208-504 Installation Manual
208-504 is a multifunctional bre splice equipment which is designed for bre connection, branching and
terminal connection. This FOSC has three single bre ports; one bre port for uncut cable usage, one testing port
(Φ6mm) and four pigtail outlets (Φ2.0mm). It is suitable for wall-mounting, aerial, pole-mounting, especially used
for FTTH bre distribution. We are always in pursue of doing research and developing the telecommunication
connection equipment. Our FOSC is your reliable choice to guarantee the quality of information transform.

4. Direction
4.1 Preparation
4.1.1 Please check the structure and type of the cable before installation. Dierent types of bre can’t be spliced together.
4.1.2 Ensure all seals are mounted correctly and take care not to over tighten.
4.1.3 Keep the working place free from moisture and dust. Don’t give any impact on the cables and don’t bent or entwine cables.
4.1.4 Use appropriate tools according to the approved standard of bre optic splicing in your region when remove the jacket of
cables and assemble the closure.
Tools as following:
4.2 Remove the jacket of cables for uncut bre installation
4.2.1 Mark the point on the cable, the length of stripping is about 180cm.
4.2.2 Remove the jacket from the marked point with a sheath stripper
NOTE: 1. Be sure not to damage bre
2. Do not use any damaged cable
3. While removing the cable sheath, please do not cut, twist or damage cable jacket. Reserve enough length to
ensure repair and maintenance in case of any accidents.
4.2.3 Cut o the extra reinforced core about 4cm from the removing point on the sheath.
4.3 Removal of the single cable jacket
4.3.1 Mark the point on the cable; the length of stripping is about 180cm from the end.
4.3.2 Remove the jacket
NOTE: 1. Be sure not to damage bre
2. Do not use any damaged cable
3. While removing the cable sheath, please do not cut, twist or damage cable jacket.
Reserve enough length to ensure repair and maintenance in case of any accidents.
4.3.3 Cut o the extra reinforced core about 5cm from the removing point on the sheath.

4.7.2 Cable installation
4.7.2.1 Insert the cable subsequently from three-hole compression gland
and three-hole sealing ring.
If there are less than 3 pieces of cable, you should seal the port by using
the plastic block.
4.7.2.2 Insert the cable through the three-hole cable port into the closure.
4.7.2.3 Fix the core into the xing pressed hole and fasten the bolts.
4.7.2.4 Put the cable on the cable xing frame and then fasten the pressed bolts to x the cable.

xtures through the button pigtail port in the en-clo
sure.
4.8.3.3 Remove the jacket of the pigtail (about 60cm)
4.9 Splice bres and store bre
4.9.1 Route the sub units tube to each splice tray (max capacity: 12cores/one tray)
4.9.2 Fix the above sub units to the entrance of the splice tray by using the nylon ties and
route bre to the splice area allowing extra length for reworking.
4.9.3 Repeat the same steps above.
4.9.4 Please embed the bre splice protective tube subsequently into the deck.
4.9.4.1 Fibre storing introduction
1. The bres should be coiled in the big circle and its length is about 330mm.
2. when the bres are coiled in the circle, with some length of bres remained,
implant the spliced bres with protective sleeves inside the bre holder. If the
remaining bre are not enough for a big circle, then coil the remaining bres round
the small circle. The length of the small circle is about 220mm.
Repeat the above steps until you meet your need of the cores. The max capacity of one tray is 12 cores (single bre).

5. Main Technical Data
• Airproof performance: airing pressure inside box 100Kpa, pointer immovability after 24 hours or no air bell within 15min when
placed under normal temperature water.
• Re-encapsulation performance: no change in the index of air-proof performance after three times of repeat encapsulation.
• Insulation resistance: ≥2×104MΩ
• Voltage-resistance strength: under the eect of 15KVDC/1min, non-puncture, no arc-over
6. Packing, Transportation and Storage
This equipment packaging is moisture-proof and earthquake-proof. The accessories are packed rst plastic bags, then into the
boxes with plastic bags for sealing. There are moisture-proof and earthquake direction signs outside the boxes.
It can’t be inverted in the transportation and be free from rolling when carrying. Please load carefully and prevent the collision.
You should prevent it from heavy rain before installation. The temperature in the transportation should be controlled between
-35 ºC to +55 ºC.
The excessive accumulation of goods should not be stored on the cartons. The Treasury should away from the erosion of corrosive
gas equipment and the temperature should be below 45 ºC and higher than -5 ºC, and relative temperature should not be high in
long-term (generally less than 75%)
