KPG-opt
1 Introduction
1.1 Purpose
1 The Optical Multi Meter KPG-opt is designed to test
fiber optic cable drums and entire fiber optic links.
2 The KPG-opt supports diagnosticians to detect
possible failures in the fiber optic link.
1.2 Description
The following main measurements are foreseen:
3 Construction teams:
- Attenuation measurement of an optical cable drum
with 2 or 4 fibers, single mode.
- Attenuation measurement of an optical signal of a
complete optical link.
- The KPG-opt automatically generates a Good/Bad
calculation of the measured values.
4 Diagnostic:
- Power measurement of an optical signal
2

KPG-opt
- Optical power source with selectable power level
- Optional transmission of user specific data frames

4.2 Design
13 The KPG-opt is built in an shock resistant plastic
housing with a ruggedized keypad with four keys.
14 An LCD display with four lines shows the functions
and the results of the measurements. The menu
guidance simplify the operations.
15 Two optical connectors are mounted at the side to
enable easy connection of the fiber optical cable.
16 The KPG-opt is battery operated. The battery cover
is secured with two quick-lock screws which can be
easily opened with a coin, knife or screw driver.
On some versions of the KPG-opt a jack is located at
the side to connect an external power supply.

4.3 Operation
17 The KPG-opt is operated with four keys. The
available menus are shown in the display and the
required functions can be easily selected with the
menu keys.
The results of the measurements are shown in the
display and some tests are rated with a good/bad
indication.
The device is switched off by pressing the power
button for approx. 3 seconds or, in case of non-use,
the automatic switch-off is activated after 3 minutes.

KPG-opt
5.2.1 Power meter
The KPG-opt measures the optical power which is
received through the optical cable.
2626
2727
2828
The Receiver is calibrated between a range of −35
dBm to 0 dBm to measure optical power at the main
connector.
An optional attenuator cable can be used to lower
the signal.
16

KPG-opt
5.2.2 Test frame (option)
The KPG-opt can be optionally prepared to generate
„Test Frames“ which can be detected by the
equipment in the system. This feature can be used
for diagnostics and function checks.
2929
3030 The output power can be adjusted with the <Select>
key within the range of −5 to −15 dBm in 1 dB Steps.
31 The max. data rate for test frames is limited to <34
Mbps.

A continuous optical signal is generated and sent to
the main connector with constant power.
The output power can be adjusted with the <Select>
key within the range of –3 to –12dBm in 1 dB Steps.
An optional attenuator cable (PK-opt -18 dB) can be
used to lower the signal by 18dB.
