1. Introduction
The PM 215 optical power meter is a small, pocket size low cost item. The
small size does not prevent the optical meter fulfilling all the technical
requirements for field equipment. The unit can be easily carried in the pocket or
on a belt. It can be placed within rack mount ODF’s with the display on the top
or on the side. The Li-pol rechargeable battery ensures a long term working time
with a minimum life time of 2 years. The unit is able to store 100 measurements
which can be uploaded to a PC and managed with SmartProtocol software.
The instrument can be used separately to measure absolute or relative
optical power in optical networks or with the LS-800 Optical Light Source,
LS-215 or OFT 820 Loss Test Set for optical loss measurement on
singlemode and multimode fiber cable at six working wavelengths.
2. Features
•Small size, light weight
•Six working wavelengths
•Absolute and Relative optical power measurement
•Internal two level memory structure
•Capacity up to 100 measurements
•SmartProtocol SW – generation of test reports
•Data exporter
•USB port for:
Charging the battery
Data upload to PC
Firmware upgrade
•Built-in Li-Pol rechargeable battery pack
•Auto Off
•Battery status indicator
3. Application
•Absolute or relative optical power measurement.
•Optical network testing.
•Measurement output power of optical transmitters.
•Measurement input power at optical receivers.
•Measurement attenuation in fiber cabling, in conjunction with the LS-800
Optical light source, LS-215 or the OFT 820 Loss Test Set.
•Measurement loss of connectors, splices, adaptors, switches and other fiber
optic components.
•Easy and quick identification of failure points in fiber optic networks
•Suitable for SM and MM applications.

6. Safety information
The PM 215 instrument emits no optical power itself and does not create any hazards
to the user. WARNING!
•Never use magnifying devices to inspect optical fiber ends unless you are sure
that no optical power is being emitted.
•Use only magnifying devices with a built-in infra-red filter to ensure safety.
•During operation, testing or maintenance of a fiber optic system, never look into
an active fiber optic cable. Infrared radiation may be present and permanent eye
damage can result.
•Avoid direct exposure to the beam.
•Do not activate the laser when there is no fiber attached to the optical output
connector
Under no circumstances should you look into the end of an optical cable attached to
the optical output when the device is operational. Laser radiation can seriously
damage your eyesight.
7. Maintenance
7.1 Battery care
The PM 215 comes equipped with a built-in charger and internal battery pack.
•Before using the PM 215 for first time, charge fully battery pack.
•Use the USB charger, cable and USB port for charging.
•Charging is not recommended until battery status is 30% or less.
Recommended charging time of battery pack is 4 to 7 hrs.
•We don’t recommended charge the battery pack fully before storing PM 215
(optimal value is about 70 %).
•If you are not going to use the PM 215 for long period, charge the battery
pack once every six months.

•The battery pack is a consumable. Repeated charging and discharging
degreases battery pack life. Please contact OPTOKON for battery pack
replacement.
•Battery status informs about current energy of battery. In case PM-215 has
fully battery charged, is displayed this char „“(figure 2).
Figure 1: Battery status
Figure 2: Status of fully chargered battery
7.2 Instrument care
•During storage and transport keep the instrument in its carry case to protect
against crushing, vibration, dust and moisture.
•Where possible keep the instrument away from strong sunlight.
•Clean the instrument housing using alcohol or other cleaning agents. Acetone or
other active solvents may damage the case.
•The instrument is resistant to normal dust and moisture, however it is not
waterproof. If moisture does get into instrument, dry it out carefully before
using it again.
7.3 Optical connector care
•Cleanliness will affect the performance of an optical fiber system.
•All connectors and fiber end faces need to be clean prior to testing.
•Clean all connectors, adapters, and attenuators before making any connections.
•Use appropriate optical cleaning supplies to keep connectors and adaptors free
from contamination.
•The following cleaning materials are recommended and can form part of your
cleaning kit:
- Lint-free laboratory wipes.
- Isopropyl alcohol in pressurised dispenser
- Lint free pipe cleaners
- Clean, dry, oil-free compressed air

Figure 3: PM215
Press “ ” key to turn the unit on or off.
After switching on, the type of device, serial number and firmware version will be
displayed (figure 4).
The unit always starts up with displaying the settings when it was switched off. For
example, if absolute mode measurement, wavelength 1550 nm and Auto Off is
selected and the unit is switched off, after pressing the ON button, the unit will start
up with the same settings.

In the absolute power measurement mode the absolute value of the optical signal in
dBm units is shown on the display.
This screen will appear after the instrument is switched on and information regarding
the type of device, serial number and firmware version will appear
(if the unit was switched off in the “absolute power measurement mode”).
[
λ
]
Selects 850, 1300, 1310, 1490, 1550, 1625 nm wavelengths.
[REL]
Activates the relative power measurement mode (unit dB).
Recalls the last set reference for a selected wavelength.
Goes to menu #2.
8.1.4 Menu #2 – Relative power measurement mode
If the relative power measurement mode is on, the value of the optical insertion loss
in dB units which corresponds to the performed reference is shown on the display.
This screen is displayed after the instrument is switched on and information
regarding the type of device, serial number and firmware version is described
(if the unit was switched off in the “relative power measurement mode”).
