2.2.3.2.3 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.

image034

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;

Note: When the diameter of cable is more than 14mm, take down liner of cable pressed button.

④ Lead the fiber which need optical spilt to splicing tray with splitter(The end try), like the pictures

image036

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.

image043

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

Important:

1. Take care while sealing the cable entry ports

2. Please note the direction of the liners when plugged into the cable port.

2.2.4 Fiber splicing, coiling and mark

2.2.4.1 Fiber splicing and mark

2.2.4.1.1 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.

2.2.4.1.3 Fusion sequence

2.2.4.1.3.1 Please agglutinate the splitter in the tray

2.2.4.1.3.2 After coiling the splitter pigtail, please insert the adaptor into the port of tray fixing plate. Please refer as the picture.

2.2.4.1.3.3 Please lead the pigtail of splitter input port into the tray(Splitter installation place) and make splicing with cable needed optical split

2.2.4.1.3.4 Please lead the pigtail of splitter output port into other trays and make splicing with output cable.

2.2.4.1.3.5 Please make coiling of the rest fiber after splicing, then cover the tray

Note: Mark must be clear for the convenience maintenance later

2.2.4.2 Coling


While coiling, please refer to following pictures. Please open the tray as following pictures.

image064


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.

2.2.4.2 Close all tray, and fix all with tape.

2.2.5 Assembling

2.2.5.1 Put the seal tape and desiccant into body, install the cover of body, and fasten the cover and base with clamp.

Reassembling

3.1 Reopening

Open body as 2.2.3.3

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 2.2.4.2, 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.
