Integrated wiring system

Modern

science

and

technology

progress

has

made

rapid

development

of

computer

and

network

technology,

provides

a

more

powerful

computer

processing

capacity

and

network

communication

ability.

The

computer

and

network communication technology can greatly improve the modern enterprise

production

management

efficiency,

reduce

the

operation

cost,

and

makes

the

modern

enterprise

can

obtain

more

effectively

and

timely

decision

market

information,

provide

more

quickly,

more

satisfactory

service

to

customers,

in

the

competition.

The

computer

and

network

communication

technology

has

become a key factor in the success of the company.

Integrated

cabling

system

in

order

to

meet

the

development

needs

is

specially

designed

a

set

of

cabling

system.

For

modern

buildings,

such

as

the

body,

it

adopted

a

series

of

nerve

of

high

quality

standard,

modular

combinations of material, the voice, data and image and control signal system

using

uniform

transmission

media,

through

comprehensive,

integrated

unified

planning design in a set of standard cabling system in modern architecture, the

three

subsystems

will

connect

organically,

and

system

integration

for

the

modern architecture provides a physical medium. Structured cabling system can

directly

related

to

the

success

of

the

modernization

of

the

building,

choose

a

high quality of integrated wiring system is of vital importance.

Computer and communication networks are dependent on wiring system as

the physical basis of network connections and information transmission channel.

The traditional single application on a particular special layout techniques, lack

of

flexibility

and

development

of,

can

not

meet

the

rapid

development

of

modern

business

needs

of

network

applications.

The

new

generation

of

structured cabling systems provide the user the required data, voice, fax, video

and

other

information

service

connections,

which

allows

voice

and

data

communications

equipment,

switching

equipment,

information

management

systems and equipment control system , security system connected to each other,

but

also

to

make

these

devices

with the work area of voice or data terminals associated with all the cables and

wiring

components.

Cabling

system

composed

by

different

series

of

components,

including:

transmission

media,

line

management

of

hardware,

connectors, sockets, plugs, adapters, transmission electronic circuits, electrical

protection equipment and support. Compared with the previous wiring, cabling

system features can be summarized as:

Practicality:

after

the

implementation

of

cabling

systems

will

be

able

to

adapt

to

the

modern

and

future

communication

technology

development

and

implementation of voice, data, unified communications, signal transmission.

Flexibility:

wiring

system

can

satisfy

the

requirements

of

various

applications, information points to any connection of different types of terminal

equipment,

such

as

telephone,

computer,

printer,

computer

terminal,

electric

machine, various sensors and image monitoring equipment.

Modularity: integrated cabling system in fixed in buildings, the level of all

cable

connectors

are

basic

type

of

the

standard,

all

voice,

data

and

interconnection

of

building

automation,

network

and

image,

with

convenient

use, equipment, change, management and expansion.

Scalability:

integrated

wiring

system

is

for

future

expansion,

more

use,

easy to expand into new equipment.

Economy: the integrated wiring system enables managers, and at the same

time,

reduce

the

modular

structure,

work

because

of

the

difficulty

of

future

changes greatly reduced the cost or moving system.

General:

to

meet

the

standard

of

international

communication

and

computer

network

topology

structure,

can

adapt

different

transmission

speed

communication

can

adapt

to

the

requirement,

can

support

and

accommodate

various computer network operation.

1 workspace subsystem

Purpose

is to

realize the workspace terminal

equipment and level of

connections

between

subsystems,

the

terminal

devices

connected

to

the

information

socket

connection

cables.

Workspace

to

cable

a

building

complex

of

other

buildings of the communications equipment and devices, is part of a structured

cabling

system

to

support

the

provision

of

buildings

in

the

hardware

required

for communication between. It consists of cables, fiber optic cable and into the

Building Department, over-current over- voltage protection equipment and other

related electrical hardware, commonly used medium is optical fiber.

Compared

with

the

traditional

routing,

integrated

wiring

construction

as

a

modern information transmission system, its main advantages are:

Traditional wiring specification due to lack of a unified, user must choose

a

variety

of

different

of

cables,

connectors

and

wiring,

resulting

in

duplication

of

cable

laying

waste,

lack
