52 seal gasket
M55 compressed bolt
184.108.40.206.3 Large cable port installation procedure (①-⑥)
① Screw down the plastic bolt of the big port, thread the stripped cables through the M55 hexangular compressed bolt (plastic),∮52 washer, connective blocker, ∮52 rubber seal gasket, connective blocker, ∮52 washer.
② Make cable thread large cable entrance in base
③ Loosen the button on the top of steel core fixed pole and thread the steel core into the retained hole of the steel core fixed pole; and then tighten the bolts, fix the cable to bracket with press button;
④ Lead the fiber which need optical spilt to splicing tray with splitter(The end try), like the pictures
⑤ Cable sealing
Connect two metal blocks and two ∮52 washers (thread the two holes on the connective blocker through two protruded poles on the ∮52 washers) and subsequently press ∮52 washers and ∮52 rubber seal ring into the big round cable inlet, then tighten the M55 hexangular pressed bolts using a screwdriver.
Note: Due to the limitation of space, make sure to tighten the hexangular bolts subsequently according to numbers in the following picture.
220.127.116.11 Lead small inlet cable(branch cable) into closure
There are 4 small ports for cut cable.
18.104.22.168.1 Components list for small cable port(branch cable)
Fix the in and outside part
09L4 sealing ring
For the sealing of closure
09L4 sealing ring inside lining(∮8-12mm)
Dia of Cable<∮12
Dia of Cable<∮10
22.214.171.124.3 The setup steps for small port(branch cable) (①-⑧)
① Screw out the nut, take the seal parts, and screw down the press
button with tool
② Through the stripped cable into M31 Nut(plastic), plastic washer
and seal gasket.
Note: When diameter of cable <∮10, please use seal gasket Ⅱand seal liner for guarantee the sealing performance.
③ Through the cable into small port to closure;
④ Loose the steel core fixing pole, through the steel core to hole of pole, and screw down the bolt.
⑤ Fix the cable to bracket with press button.
⑥ Installation at the same time if grounding.
⑦ The seal for cable.
Press the seal gasket(liner only for necessary) and plastic washer to small port. Screw the M31 nut with spanner tightly for perfect seal.
⑧ Conduct the branch cable to tray
Measure the distance from cable fixing place to second or third tray port,
strip the fiber tube, fix them to inlet of tray with nylon ties.
Note: ① If no cable in inlet, please put the plastic plug to inlet, crow down the M31 nut, all will be perfect seal.
② If grounding, we will connect the steel core fixing device first before leaving factory.
Sealing of the cable entry ports
1. Take care while sealing the cable entry ports
2. Please note the direction of the liners when plugged into the cable port.
Cable diameter: ∮12-17.5
Cable diameter: ∮10-12
Cable diameter: ∮8-10
Use plugs to seal if without installation of cable
2.2.4 Fiber splicing, coiling and mark
126.96.36.199 Fiber splicing and mark
188.8.131.52.1 Remove the layer of the splicing fiber using the bare stripper, make it clean with gauze and alcohol. Then cut the fiber by cutter(Length according to the coiling). Devices in pictures are showed just as examples.
|Tube Stripper||Naked Fiber Stripper||Fiber Cutter|
184.108.40.206.2 Making the regular fiber splicing, record the parameter and mark the cable for the maintenance later. Devices in pictures are showed just as examples.

220.127.116.11.3 Fusion sequence
18.104.22.168.3.1 Please agglutinate the splitter in the tray
22.214.171.124.3.2 After coiling the splitter pigtail, please insert the adaptor into the port of tray fixing plate. Please refer as the picture.
126.96.36.199.3.3 Please lead the pigtail of splitter input port into the tray(Splitter installation place) and make splicing with cable needed optical split
188.8.131.52.3.4 Please lead the pigtail of splitter output port into other trays and make splicing with output cable.
184.108.40.206.3.5 Please make coiling of the rest fiber after splicing, then cover the tray
Note: Mark must be clear for the convenience maintenance later
While coiling, please refer to following pictures. Please open the tray as following pictures.
Note: ① In coiling, the bend radius> 30mm. If radius too small, it will affect that fiber, even fiber break. With the long time, it may appear the broken fiber.
③ When coiling, watch out the distortion direction, usually it is “8” type, and twist out any fiber. Put out any fiber. Put the all fiber to under baffle to avoid damage fiber.
220.127.116.11 Close all tray, and fix all with tape.
18.104.22.168 Put the seal tape and desiccant into body, install the cover of body, and fasten the cover and base with clamp.
Local construction(It depend on the user). The external ground wire must be safe. Then monitor the internal optical fibers, to be sure whether the optical fiber is damaged.
2.3 Laying installation of closure

Pole mounted Air mounted Manhole and handhold mounted
3 Reopening and maintenance
This section contains the following connects
Maintenance and expansion
Open body as 22.214.171.124
Note: If there is protective air or other air in body, please release the air by valve firstly.
3.2 Maintenance and expansion
3.2.1 Choose the fiber need maintenance, open the tray as 126.96.36.199, find the splicing fiber in the cable needed maintenance to maintain them.
3.2.2 While expanding, choose the inlet no any cable, loose the nut with spanner, take out the plug and other seal components. If the plug is too tight, use the screw driver to take out seal parts.
3.2.3 Introduce that cable need expanding, handle them as second section.
3.2.4 If need distribute optic cable in expanding, confirm the type and diameter of cable. Our regular small port can meet the cable of ∮8-∮17.5mm, if introduce other type cables, please contact us to enclose some relative seal parts before expanding. Please refer to following sealing elements for small ports.
