7.2 Routing Pre-Connectorized Indoor/Outdoor Fiber Optic Cable

Fiber

optic

cable

termination

typically

consists

of

routing

a

pre-connectorized

indoor/outdoor

fiber

optic

cable

between

the

cabinet

and

an

external

splice

tray

enclosure,

securing

the

cable

to

the

cabinet,

breaking

out

the

individual

jacketed

pigtail

fibers

inside

the

cabinet,

and

connecting

the

fibers

to

the

WDM

(optional)

or

STM.

Cable

storage

spools

is

provided

on

the

interior

wall

of

the

cabinet

to

accumulate

excess

indoor/

outdoor

cable

length

and

also

serve

as

a

long-term

storage

location

for

redundant

cable.

All

fiber

optic

cable

connections

within

the

RU

require

SC

cable

connectors.

7.2.1 Terminating the Indoor/Outdoor Cable(WDM Feature Not Installed)

Use

the

following

procedure

to

terminate

the

individual

pigtails

in

the

indoor/outdoor

cable:

1. Insert

an

appropriate

sized

compression

fitting

into

the

water-resistant

connector

installed

on

the

bottom

of

the

cabinet

(see

Figure 6).

2. Route

the

stub

end

of

the

pre-connectorized

indoor/outdoor

cable

down

throuth

the

water-

resistant

connector

to

the

external

splice

tray

enclosure.

3. Tighten

the

compression

fitting

on

the

cable

port

to

secure

the

cable.

4. Strip

back

the

outer

sheathing

of

the

customer-provided

indoor/outdoor

cable

inside

the

cabinet

to

allow

the

connectorized

individual

jacketed

pigtails

to

be

routed

to

the

STM

or

cabinet

storage

spools.

a. Connect

the

forward

path

fiber

to

the

PORT

1

SC

connector

on

the

STM

(refer

to

item

1

on

Figure 1).

b.

Connect

the

reverse

path

fiber

to

the

PORT

2

SC

connector

on

the

STM

(refer

to

item

2

on

Figure 1).

c. On

units

with

the

Diversity

feature,

connect

the

secondary

reverse

path

fiber

to

the

PORT

3

SC

connector

on

the

STM

(refer

to

item

3

on

Figure 1).

5. Coil

up

the

excess

cable

length

on

the

cabinet

cable

storage

spools.

7.2.2 Terminating the Indoor/Outdoor Cable (WDM Feature Installed)

Use

the

following

procedure

to

terminate

the

individual

pigtails

in

the

indoor/outdoor

cable:

Note:

The

routing

of

an

OSP

fiber

optic

cable

from

the

HU

to

a

splice

tray

enclosure

in

the

vicinity

of

the

RU

and

the

splicing

of

selected

OSP

cable

fibers

to

fibers

in

the

indoor/

outdoor

cable

is

the

responsibility

of

the

customer.

Warning:

To

avoid

exposure

to

to

invisible

laser

radiation,

do

not

look

into

the

ends

of

any

optical

fiber

or

bulkhead

connector.

Never

assume

laser

power

is

turned

off

or

that

the

fiber

is

disconnected

at

the

other

end.

Use

an

optical

power

meter

to

identify

active

fibers.

Always

place

a

protective

cap

over

any

unused

bulkhead

connector

or

optical

fiber

connector.
