Product Instruction for GP30Z-B Vertical Fiber OpticalClosure

Product Instruction

GP30Z Vertical Fiber Optical Splice Closure

1.jpg2.jpg

1. 1 General

GP30Z vertical fiber optical splice closures are butt-type closures used in the outside pant network

to ensure mechanical and optical continuity between incoming and outgoing cables and avoid any

moisture penetration. All cable connection is completed through the bottom of the closures.

1.2 Applications

GP30Z vertical fiber optical splice closures can be installed in outside plant direct buried,

manholes(dimension min:1.20×0.90×1.3) or aerial locations(vertical or horizontal fixation)

1.3 Material

GP30Z closures are made of a tough chemical- resistant and tension active material (quality PP

engineering plastic) and a gasket seal.

The base and dome are sealed with a clamp and an O-ring system.

The cable seals are made of heat shrinkable material.

1.4 Cables

GP30Z closures have one oval cable entry port which can handle 2 cables(φ6-φ22) and four large

circular ports will handle one cable(φ6-φ17) each. The closure accommodates all common trunk

and feeder cable sizes (from 6 to 19mm diameter).

The closure accommodates as minimum:

- 1 “passing through” cable

- 4 cables terminated in the closure

Cables are fixed by the strength member and maintained by circlip.

1.5 Fiber management

GP30Z closures are designed for separate management for passing through buffers.

The trays are designed for separated management for fibres in service and non connected

fibres.

Each tray allows arranging 36 fusion sleeves. 144 fusions as maximum can be accommodated

in the closure.

1.6 Products Features

Reasonable design with no salient angle or cutting edge

Ease installation,

Requiring no special tools or complicated training procedures,

Closure principle is fully mechanic, no use of flame or resin.

Change or installation of a new cable is possible without risk for the existing fibers,

Allowing access to fibre core with minimum impact on fibre cable inlets water-tightness.

Cable inlets and cover to access to fibre core are separated.

The closures are easily re-opened to allow access to the splices.

It allows 60 opening/closing operations at minimum without replacing any part (joint).

Designed and tested to Telcordia™ GR-771 aerial weather tight closure requirements and

insect seal

Minimum fiber radius maintained at 30 mm throughout

Applicable environment temperatures: -40°C~+65

Pressure: 70~106Kpa

Life expectancy: 25 years

MII standard: YD/T814.1-2013 Fiber Optical Splice Closure Part One: Outdoor Fiber

Optical Splice Closure

Dustproof and waterproof grade: IP68

INSTALLATION INSTRUCTION

in Chinese or English

3. Installation Instructions

1 Preparation for the cable entry ports

1.1 Select the appropriate port to open on the base. Cut the end off the selected port at the

ridge with a hacksaw.

1.2 Clean the hacksaw teeth and the base.

2

Preparation for the fiber joint end (Figure 1)

1.1 Slide the heat shrinkable tubes over the cables. Insert min. 2m cables though the opened

port.

1.2 Remove the outer cable sheath and shield if present following the local practices.

1.3 Strip away any insulation present on the central member all the way back to the ring cut.

(Trim the central member 5-8mm beyond the edge of the square washer).

1.4 Clean the remaining buffer tubes, exposed fibers, strength members with cleaning tissue.

1.5 Install one transportation tube on each buffer tube and slid it down to the sheath ring cut.

Install Cables

2.1 Abrade the port and cable with the supplied abrasive strip, and remove any abraded material from the

port and sheath with a clean, dry cloth. ( Figure 2) (Figure 3)

8.jpg


2.2 Place the central member between the square washer and the ring, and tighten the bolt to secure the

central member.

2.3 Fix the cables on the cable fixture with hose clamps. Figure 4

2.4 Wrap one circle of self-adhesive tape around the cable at a spot 30mm from the interface of inlet

port.(Figure 5) Slide the tubular cable port seal up around the port and cable. Wrap one lap of aluminum

tape around each cable. Be sure that the inside edge of the tube butts against the base. Squeeze the tube

down onto the base and place a white pencil mark on the cable at the end of the tube. Slide the tube back

off the port. The edge of the aluminum tape closest to the closure should be 10mm inside the white mark

on the cable. (Figure 6) Install the branch-off clip if the oval ort is selected. The clip’s base must not

touch the tube. (Figure 7)

10.jpg

2.5 Using a hot-air gun or gas torch, begin shrinking the tube at the end closest to the base of the closure.

Direct the air around the tube until the green paint turns black. Continue heating the remainder of the

tube as evenly as possible until it has completely comforted to the cable(s). (Figure 8)

3. Fiber Organizing and Splicing

3.1 Splicing of single core fiber cables

3.1.1 Cut off the fiber protector tube at about 15mm of the organizer cassette bottom (Don’t destroy t he

fiber cable), and fix it with 2 tie-wraps.

3.1.2 Splice and test the fiber cable according to the specified installation procedure, and fix the splices in

the splice holders and make the marks. Then put the spare fiber in the cassette orderly. Note: the

coiling dia. of the fiber should be no more than 60mm. (Figure 9)

12.jpg


3.1.3 Each single fiber splicing tray has 36 splice holders and 1 or 2 splices can be placed in each splice

holder and 36 fiber splices can be placed in each splicing tray at the most. All the splices must be

placed orderly and make the marks. Replace the tray cover.

4. Ground Feed Through

A sealed grounding feed-though bolt can be pre-mounted in the base to connect metallic components to an

external ground.

5. Closing and mounting closure

Hang the O-ring on top of the dome. Align arrows and mount dome on base (Figure 10). Install clamp

around the base/dome interface. Metallic lashing straps should be placed around the dome to hold closure in

place.

6. GP30Z fiber optic splice closure is compatible with various installation methods. It can be installed on wall,

Figure 11)(Figure 12)(Figure 13

7. Security Data

The fiber optic splice closures should be stored in the well-ventilated shelves with the min. 20cm distance

from the ground and the walls. The temperature of the warehouse should be -25+40 and the humidity

should be not more than 85%at 30.

When operating the splices with a hot-air gun, please take note of these warnings:

Keep the area clear of all combustible materials and gases, such as gasoline, solvents, and dirty rags.

Consult your company approved practice for procedures to clear and ventilate the work area to avoid the

potential for fire and/or explosion.

The cleaning tissues provided in the kit are extremely flammable, and should not be exposed to excessive

heat or open flame.

Do not immerse the hot-air gun in water, as electrical shock could occur.

Flash test the closure to no more than 5 psi.
