If there are a large number of wire troughs, a transportation tool

is required because an electric vehicle is insufficient.

Examples of various bends mentioned in the preceding table:

2.6 Deployment Precautions

The pull force for routing optical cables varies greatly with in-wall pipes. Therefore, the pull should be added to the pull tape. Before the deployment, the deployment personnel can use a tension meter to measure the force.

Optical cables must be routed out from the upper side of the cable wheel and maintain a sufficient slack arc shape. Ensure that the optical cables are not twisted

or curved.

Pay attention to the pulling strength and bending radius of optical cables, and prevent optical cables from being entangled, twisted, damaged, or trampled.

When routing optical cables, confirm the reserved length required for other operations such as splicing. It is recommended that the reserved length be greater

than 1.5 m.

Two technicians who cooperate with each other during optical cable routing need to properly communicate with each other.

After optical cables are routed, check whether the optical cables are in good condition and take moisture-proof and dust-proof measures for the optical cable ends.


Wi-Fi 3 In-Wall Wiring Solution


3 In-Wall Wiring Solution

A wire threader is made of metal. If there are strong-current cables in an in-wall pipe, deployment is not recommended.

This solution applies to residences that have been decorated. Before the deployment, confirm the in-wall pipes (such as an in-wall pipe from the home distribution box to the TV background wall in the living room).

3.1 Reusing Cables for Installation

3.2 Using a Spring Wire Threader with an Olive-shaped Head to Route the Cables

3.1 Reusing Cables for Installation

1. Before the deployment, use an optical power meter to check whether the RX optical power meets the requirement.

− If no, stop the deployment and reconstruct the drop cable.

− If yes, record the value.

2. Determine and confirm the cables or embedded ropes that can be reused (movable lines for short) with the customer.

3. Wrap the head of the movable line with the pull tape, and bind them using mesh tape.




4. Pull out the movable line from the other end to deploy the pull tape in the pipe.

5. Measure and select a flat drop cable jumper of proper length. The flat drop cable jumper has two specifications: 20 m and 50 m.

6. Wind the pull tape and the optical cable (about 0.5 m) together as shown in Figure 3-1. Bind the remaining part evenly with mesh tape at 3 or 4 positions as

shown in Figure 3-2. When binding the pull tape and optical cable, ensure that there is no edge or angle. For example, the right angle of the SC connector needs to be bound.

Figure 3-1 Winding the pull tape and the optical cable

Figure 3-2 Binding the cable and pull tape with mesh tape

When the in-wall pipe is empty, the optical cable with an SC connector can be fixed and

wound together to avoid fiber splicing. Note that the blue rectangular shell must be removed from the SC connector to be routed through a pipe. The coiling radius of the optical cable must be greater than 50 mm, and a protective cover must be installed for the optical cable connector.

The method of removing the blue rectangular shell of the SC connector is as follows: On a flat plane, hold the blue shell with two fingers, and push the shell towards the flat plane as shown in the following figures. The blue shell can be easily removed.




When two cables (two optical cables with SC connectors or one network cable plus one optical cable) are pulled at a time, they must be bound alternately. The distance between the heads of the two cables must be at least 20 cm. Ensure that the two connectors and cables are completely bound. Wind the two cables and the pull tape. It is recommended that they are bound with mesh tape by one layer every 1 m.

7. Pull out the pull tape at an even speed to avoid breaking the optical cable. Two technicians are required to pull the optical cable. One feeds the optical cable and

the other pulls the optical cable so that the optical cable passes through the pipe at an even speed. Route the optical cable from the pipe, and check whether the optical cable is damaged. If there is any damage, check the connectivity of the optical cable.

8. Separate the pull tape from the optical cable, reserve a proper length of the optical cable, and route the optical cable through the pipe.

If the optical cable has an SC connector, there is no need to cut or splice the optical cable. Instead, remove the mesh tape that wraps the SC connector, reinstall the blue rectangular shell, and perform a test.

If the test result is normal, the optical cable can be normally used. Skip step 9.

If the test fails, cut off the optical cable and go to step 9.

9. Splice the cut optical cable with a new SC connector.

The following provides the method of stripping an indoor dedicated flat drop cable:

1. Insert the flat drop cable into a fiber coating stripper. Ensure that the optical cable is aligned with the cross opening as shown in the following figures.




2. Press the fiber coating stripper, insert the optical cable, and pull the optical cable with force to strip the plastic layer of the optical cable.

10. Coil the remaining optical cable with a radius greater than 50 mm, and place the coiled optical cable in the home distribution box.

11. Interconnect the drop cable with the newly deployed indoor optical cable using an SC adapter.

3.2 Using a Spring Wire Threader with an Olive-shaped Head to Route the Cables

1. Before the deployment, use an optical power meter to check whether the RX

optical power of the drop cable meets the requirement.



2. Route a spring wire threader with an olive-shaped head through the pipe at an even speed until it passes through the pipe. If the spring cannot pass through an

obstacle even with a large force, handle the obstacle as follows:

a Pass the optical cable through an assembled right-angled elbow as shown in the following figure.




b If obstacles (such as gravel and residual cables) exist, tighten the butterfly nut. If the spring can no longer move forward, pull it backwards to pull the obstacles out of the pipe.

If you encounter large resistance when pulling the spring backwards, tighten the butterfly nut. Then rotate the handle counterclockwise while pulling the spring backwards.

3. Wrap the head of the spring wire threader with the pull tape, and bind them using mesh tape.

4. Pull out the spring from the other end to deploy the pull tape in the pipe. It is recommended that two technicians cooperate with each other. One pulls out the spring, and the other sends the pull tape at the other end.

If you encounter large resistance when pulling out the spring from the other end, tighten the butterfly nut and rotate the handle counterclockwise.





6. Wind the pull tape and the optical cable (about 0.5 m) together as shown in Figure 3-3. Bind the remaining part evenly with mesh tape at 3 or 4 positions as shown in Figure 3-4. When binding the pull tape and optical cable, ensure that there is no edge or angle. For example, the right angle of the SC connector needs to be bound.

7. Pull out the pull tape at an even speed to avoid breaking the optical cable. Two technicians are required to pull the optical cable. One feeds the optical cable and the other pulls the optical cable so that the optical cable passes through the pipe at an even speed. Route the optical cable from the pipe, and check whether the

optical cable is damaged. If there is any damage, check the connectivity of the optical cable.

8. Separate the pull tape from the optical cable, reserve a proper length of the

optical cable, and route the optical cable through the pipe.

4.1 PVC Transparent Waterproof Tape

4.1 PVC Transparent Waterproof Tape

Double-fold waterproof tape is recommended for better protection.

Procedure:


optical power meets the requirement.




3. On the planned route, mark the installation position and bending reference line.

4. Install the double-fold transparent waterproof tape.

a Clean the wall or baseboard where the transparent waterproof tape is to be attached and ensure that there is no water stain or dust.

b Attach the optical cable to the waterproof tape.

i. Direct routing: Tear off the release paper from the waterproof tape, stick

the optical cable to the waterproof tape, and attach the optical cable and waterproof tape to the wall or baseboard.

(1) No baseboard: Fit the optical cable to the middle of the waterproof tape.




(2) With a baseboard: Fit the optical cable to a crease of the waterproof

tape.

ii. Layout effect

Horizontal routing: along a straight

line

If the distance is long, the optical cable is prone to be twisted. Therefore, before securing the optical cable, verify that it is straight.

Routing at an internal corner: at the

turning of a flat surface

Attach the upper part of the transparent tape to the wall, the middle part to the upper surface of the baseboard, and the lower part to the vertical surface of the

baseboard.

Fix both sides and remove bubbles.

Routing at an exposed corner: at the turning of a flat surface

Similar to the routing at an internal corner. Note that the bending radius of the optical cable at the corner cannot

exceed the normal bending range of the optical cable.

Routing at a bend angle: at the turning of a flat surface

When multiple optical cables are routed together, use other adhesive tapes to fix them to prevent them from being twisted.




Routing along a baseboard

Attach the upper part of the

transparent tape to the wall, the middle part to the upper surface of the baseboard, and the lower part to the vertical surface of the baseboard.

Ensure that the optical cable is adhered to the junction of the

baseboard and the wall.

Routing in front of a door: at the right-angle corner at a door

The optical cable is routed from the door gap. The tape at the turning point is tightly attached. A small waterproof block can be attached to protect the optical cable.

Ensure that the bending radius of the optical cable at the corner is within the

normal range.

Routed behind the door: used at the end of a wire trough

Ensure that opening and closing the door do not damage the optical cable.

Wrap the entire optical cable with waterproof tape to prevent dust and water from shortening the service life

of the optical cable.

Routing through a door gap: to pass through an obstacle, a bump, or another

object

Route the optical cable based on the door gap condition. Prevent the optical cable from being squeezed or rubbed. Ensure that the entire optical cable is protected by

waterproof tape.

If there is a rug, the optical cable can be routed along the boundary between the rug and the door frame.

c After the optical cable is secured, squeeze the air between the transparent waterproof tape and the wall or baseboard to ensure that they are securely attached.

In a home environment, it is recommended that the deployment be performed above the

baseboard.




During the attaching and deployment, prevent the optical cable from being twisted, twisted, and damaged. The bending radius of the optical cable should be greater than 5 mm, and the coiling radius should be greater than 50 mm.

When attaching waterproof tape to a door gap, do not overlap the tape to prevent the tape from being too thick.

Double-fold waterproof tape needs to be inspected and maintained regularly. Users can purchase and replace them as desired.

A user can also tear the PVC transparent waterproof tape into 2 to 3 folds as desired.

A.1 Common Spring Wire Threader

Table A-1 Specifications of a common spring wire threader

Diameter ≤ 4 mm

Material Solid 3-layer metal spring

Length 20 m recommended (purchased on demand)

1. Before the deployment, use an optical power meter to check whether the RX optical power meets the requirement.



2. Insert a common spring wire threader into the pipe through which an optical cable is to be routed.

Measures if the wire threader cannot be pass through the pipe:

If the wire threader encounters an obstacle at a turn or another place, rotate the wire threader to go into the pipe in a spiral mode, or send the wire threader to the pipe from the other end of the pipe.

Use a small amount of lubricant to lubricate the wire threader, and then try to pass through the pipe again.

If the wire threader fails to pass through an empty pipe, use a vacuum cleaner to clear the obstacles in the pipe.

3. Wrap the head of the common spring wire threader with the pull tape, and bind them using mesh tape.




4. Pull out the common spring wire threader from the other end of the pipe to deploy the pull tape in the pipe.


6. Wind the pull tape and the optical cable (about 0.5 m) together as shown in

Figure A-1. Bind the remaining part evenly with mesh tape at 3 or 4 positions as shown in Figure A-2. When binding the pull tape and optical cable, ensure that there is no edge or angle. For example, the right angle of the SC connector needs to be bound.

7. Pull out the pull tape at an even speed to avoid breaking the optical cable. Two technicians are required to pull the optical cable. One feeds the optical cable and the other pulls the optical cable so that the optical cable passes through the pipe at an even speed. Route the optical cable from the pipe, and check whether the

optical cable is damaged. If there is any damage, check the connectivity of the optical cable.

8. Separate the pull tape from the optical cable, reserve a proper length of the

optical cable, and route the optical cable through the pipe.













A.2 Through an Exterior Wiring Trough

A.2.1 Before Installation

The exterior wiring trough deployment mode has impact on the appearance of the wall.

Therefore, it is recommended that the exterior wiring trough deployment be performed at baseboards.

If holes need to be drilled through the wall, confirm the hole drilling position with the customer and obtain an approval from the customer in advance.

Determine and mark the positions of the holes to be drilled. Ensure that the wall where the holes are to be drilled is safe and the holes are away from existing pipes.

Use a proper hole drilling tool (such as an 8 mm electric hammer) to drill holes horizontally or slightly on the wall.

(Optional) Place a winding pipe in a hole to protect the optical cable.

Install wall bushings (for fixing and wire trough layout) or hole sealing troughs (for wire trough layout) on the inner and outer sides of wall holes.


optical power meets the requirement.






2. Confirm the indoor positions of the home distribution box and ONT, and plan the installation positions of ATB in each room.

3. Measure and select a flat drop cable jumper of proper length. The flat drop cable

jumper has two specifications: 20 m and 50 m.

4. Based on the installation position of the home distribution box, home decoration, and user requirements, determine the cable route (preferably the route along the ceiling, door frame, baseboard, and cabinet door). Ensure that the route is safe and covert, and avoid heat sources and dangerous sources.

5. After confirming the cable route, mark the route on the wall (pay special attention

to the bending radius of the optical cable) and clean the surface of the cable route.

6. Check whether there is any part of the line that may cause insecure fixing. If yes, work out an alternative solution. Ensure that the optical cable or wire trough is attached stably and securely after the deployment.

7. Clean the indoor cable route and remove dust.

A.2.2 Wire Trough Installation

1. Select wire troughs based on the application scenarios.

Straight trough: laid out along a straight path

Optical cable fixing trough: used to fix an optical cable in the wire at the inlet and outlet of the wire trough and at a turning point

Bend angle trough: used at the turning of a flat surface

Exposed corner wire trough: used at an outer right corner

Internal corner wire trough: used at an inner right corner

Tail wire trough: used at the end of a wire trough




Hose trough: used to route a cable through an obstacle or a protruding object

Sealing wire trough: used when an optical cable is routed through a hole in the wall

Cut a straight wire trough based on the required length. Do not separate the wire trough

cover from the trough.

Recommended wire trough specifications are as follows: 12 mm x 7 mm.

2. Use double-sided tape to fix the bottom of a wire trough.

a Verify that the wall is flat and no dust or rubbish on the wall.

b Attach double-sided tape to the marked position for a wire trough along the

cable route.

c Fix the planned bottom trough on the double-sided tape on the cable route.

A.2.3 Cable Layout

1. Lay out the optical cable to the bottom of the wire trough. Ensure that the optical cable is in a free state.

2. Close the wire trough cover and do not clamp the optical cable.

3. After confirming that the wire trough cover is tight, use a cloth to clean dirt.
