Impedance

matching

The internal resistance of signal source is

the same with characteristic impedance of

the transmission line in quantity and phase;

or characteristic impedance of the

transmission line is the same with

impedance of load in quantity and phase;

which means respectively input or output

impedance matching of transmission line.

4. Correlative Definition for MDF

Main Distribution Frame (MDF)：

is a device for connection and protection in the local

communication lines, the external lines of MDF connect the

copper-core twisted pair local

call cables

and the

internal lines connect the subscriber lines of telecom exchange or

access equipment .

Double-side

jumper MDF:

is composed of back-to-back horizontal and vertical rows, in

which the

horizontal rows are used to install exchange side

terminal blocks, and the

vertical rows are used to install cable side terminal blocks

.

Single-side

jumper MDF:

has both the jumper terminals of external and internal lines set

on the same side. A single-side jumper MDF is constructed by terminal frames and

corresponding horizontal and vertical wiring troughs, and can be lined in

multiple columns

.

The cable side terminal blocks and exchange side terminal blocks can be either

separately installed on different terminal frames or mixed installed on the same terminal

frames.

Cable side terminal block:

is used for terminating external cables and connecting

jumpers, and also

can be equipped with a protective unit

(generally known as vertical

terminal block, protective-testing connecting block, protective connecting block, external

cable terminal block , and so on ).

Exchange side terminal block:

is used for terminating intra-office cables and connecting

jumpers, and is able to implement test (generally known as horizontal terminal block,

testing connecting block, internal cable terminal connecting block , and so on ) .

Protective unit:

is used to prevent injury on the operator and damage on equipment

caused by

over-voltage and over-current

, also known as protector.

can be sorted as double-sided frame, single-sided frame, and

wall-mounted frame according to cabling mode or installation mode.

Cabinet :

can be sorted as double-sided cabinet, single-sided cabinet, and

wall-mounted cabinet according to cabling mode or installation mode.

Cable side terminal block:

can be sorted as 10/20 pair terminal strip, 100/200

pair terminal block according to distribution capacity;

Can be sorted as welding connection type, wrapping connecting type, half IDC and

half wrapping connection type and IDC connection type according to connection

mode;

Can be sorted as stationary type, revolving type according to structure;

Exchange side terminal block:

can be sorted as 8/16 pair terminal strip, 128/256

pair terminal block according to distribution capacity;

Can be sorted as welding connection type, wrapping connecting type, half IDC and

half wrapping connection type and IDC connection type according to connection

mode;

Can be sorted as stationary type, revolving type according to structure;

Protective unit: can be sorted as gas discharge tube type and semiconductor

arrester type according to the type of discharge tube;

Can be sorted as non-self-recovery type and self-recovery type according to the

characteristic of over-current device.

Impedance

matching

The internal resistance of signal source is

the same with characteristic impedance of

the transmission line in quantity and phase;

or characteristic impedance of the

transmission line is the same with

impedance of load in quantity and phase;

which means respectively input or output

impedance matching of transmission line.

connector

In fact, the RF coaxial connector is also a coaxial

transmission line, in which there are separable

electric contact unit, connecting unit and other

device for installation and termination.
