8. Location Requirements:

Location requirements for the pedestal ODC include the following:

(1) The location of the pedestal ODC shall be close to the site/plot

customer groups as much as possible so that the cable pulled towards

customers can be shorter and technical requirements (loss budgets) can

be met.

(2) The location of the pedestal ODC shall not be in a location prone to

landslides or flooding.

(3) The location of the pedestal ODC shall pay attention to the installation

location's city plan as possible widening of roads, construction of public

facilities and so forth.

(4) The location of the pedestal ODC shall be secure from external

disturbances such as vehicular traffic, pedestrians and crime. If the

location needs additional safety, crime-prevention solutions such as

fences or locks may be considered.

(5) Foundation of ODC & Hand hole location is related closely.

Please follow the arrangement below figure:

9. Above-ground Installation Requirements:

Above-ground installation requirements are as follows:

(1) Cabinet stakes protective toward the pedestal ODC may be considered

so as not to accidentally struck by a vehicle in some specific location and

the stakes may be installed either at the front or at the two sides of the

pedestal ODC for other specific location. The installation of the safety

stakes is as shown below.

(2) The pedestal ODC shall be mounted on the concrete base/foundation

with minimum depth of 600mm and height of at least 500mm from ground

level. The foundation depth and height may be adjusted along with heavy

loads and capacity of the pedestal ODC. The foundation length and width

may be adjusted along with length and width of the pedestal ODC to be

installed. The foundation above ground level shall be plastered/smoothed

and the top surface of the concrete base shall be sloped so that water

does not stagnate around the pedestal ODC, especially for high flood-

prone areas, the foundation shall be adjusted.

(3) The foundation is made of concrete with a ratio of cement, sand, rock

fragments = 1 : 2 : 3 (example). Please contact the supplier of cement for

the best mix ratio or follow contractors’ best practices. The foundation

size may be adjusted along with the size of the pedestal ODC and the

foundation can be made on the spot or in advance (precast).

Please see "Annex " attached for more detail.

(3) The foundation is made of concrete with a ratio of cement, sand,

rock fragments = 1 : 2 : 3 (example). Please contact the supplier of

cement for the best mix ratio or follow contractors’ best practices. The

foundation size may be adjusted along with the size of the pedestal

ODC and the foundation can be made on the spot or in advance

(precast).

(4) The bottom of the pedestal ODC (cabinet root) shall be firmly

attached to the concrete foundation with appropriate depth not to close

root/skirt cover as the following cabinet installation image on concrete

base/foundation:

(5) The interior of the foundation shall be made hollow and have sufficient

space for laying fiber optic cables, power supply cable and grounding

wires if applicable.

(6) In order to avoid the insect after the cables installed, their cavity

should be closed with seal material/paraffin or so. Please follow

contractors’ best practices.

(7) For the convenience of operating personnel, made cabinet shop floor

on site if possible. The size of the working floor may have length 150 cm

and width 135 cm and it can be adapted to the situation on the ground. An

example of the image for the work floor space at the site is the following.

16. Safety Precautions and Best Practices:

Safety Glasses:

Safety glasses for eye protection should be worn when handling

chemicals, bare fibers, cordage and fiber optic cables.

Chemicals:

Chemicals for cleaning should be handled with care along with health,

safety and environmental instructions on suppliers’ instructions and

material safety data sheets, your company’s instructions and regional

regulations.

FAST connectors and mechanical splice (if applicable) contain index

matching gel. It may be ignited by heat, sparks or flames. Contact with

eyes may cause irritation. Prolonged and/or repeated skin contact may

result in mild irritation or redness.

Upon eye contact, immediately flush eyes with plenty of water for at least

15 minutes as first aid measures and get immediate medical attention.

Upon skin contact, wash off with soap and water as first aid measures and

get medical attention if symptoms occur.

Please contact us for more details.

Bare Fiber Handling:

Cleaved or broken glass fibers are sharp and can pierce the skin or

damage the eyes. Use tweezers when handling pieces of glass fibers.

Recommend to use a fiber cleaver with a fiber scrap collector.

Fiber/Cable Handling:

Optical fiber and fiber optic cable may be damaged by excessive forces.

Please contact suppliers for proper handling.

Laser Safety:

Never look directly into the end of a fiber and connector. Laser light that

may be invisible can damage your eyes.

Cleanliness of Fiber Optic Connectors:

One of failure cases of fiber optic connectors is caused by

contaminations on connector end-face. They could result in worse

insertion/return loss and failure of the end-face. Recommend to clean the

end-face of connector before mating as one of the best practices.
