1 Introducing the FOT-5200
CWDM Analyzer
The FOT-5200 CWDM Analyzer is designed to measure and mark
wavelengths in order to measure the exact power independently for each
coarse wavelength division multilplexing (CWDM) channel. This
instrument is portable and made to be appropriate to the outside
environment.
When using a broadband powermeter, only the total optical power of the
combined CWDM channels can be measured. When several wavelengths
are sent at once, the exact value of each wavelength cannot be measured.
Thus for CWDM, which functions over several wavelengths, a device that
can distinguish the wavelengths must be used.
The FOT-5200 is developed to measure exact power and is adaptable to
the various network conditions. It is especially suitable for outer
environments and is compact, therefore easy to carry.

3 Setting Up and Operating
your FOT-5200
Cleaning and Connecting Optical Fibers
To connect the fiber-optic cable to the port:
1. Inspect the fiber using a fiber inspection microscope. If the fiber is
clean, proceed to connecting it to the port. If the fiber is dirty, clean it as
explained below.
2. Clean the fiber ends as follows:
2a. Gently wipe the fiber end with a lint-free swab dipped in isopropyl
alcohol.
2b. Use compressed air to dry completely.
2c. Visually inspect the fiber end to ensure its cleanliness.
IMPORTANT
To ensure maximum power and to avoid erroneous readings:
Always inspect fiber ends and make sure that they are clean as
explained below before inserting them into the port. EXFO is
not responsible for damage or errors caused by bad fiber
cleaning or handling.
Ensure that your patchcord has appropriate connectors. Joining
mismatched connectors will damage the ferrules.

Turning Unit On and Off
3. Carefully align the connector and port to prevent the fiber end from
touching the outside of the port or rubbing against other surfaces.
If your connector features a key, ensure that it is fully fitted into the
port’s corresponding notch.
4. Push the connector in so that the fiber-optic cable is firmly in place,
thus ensuring adequate contact.
If your connector features a screwsleeve, tighten the connector
enough to firmly maintain the fiber in place. Do not overtighten, as this
will damage the fiber and the port.
Note: If your fiber-optic cable is not properly aligned and/or connected, you will
notice heavy loss and reflection.
Turning Unit On and Off
The Power button ( ) is used to turn the unit on and off.
If you press Power for more than 1.5
seconds, the logo appears and the unit
beeps. It then moves to Total Power,
which is the basic channel.
Press Power for more than two seconds
to turn the power off.
To adjust LCD Back Light:
It is possible to adjust the brightness of
LCD's back light to one of two levels by
pressing Power for just a short time.

User-Defined Channels (USER SCAN)
USER SCAN ( ) is a button assigned to scan only channels defined by
the user.
To set up USER SCAN:
1. Press MENU to change to the menu screen.
2. Use the arrow buttons to select
USER SCAN, then press ENT.
As the channel values that users
mainly use are provided in the
above screen, it is easy to set up the
channel value that you want.
3. If you press ENT after selecting
USER SELECT, you can select the
channel that you want. If you then
press ENT, it changes from OFF to ON.
The set up value is automatically saved
if you come out using the ESC key after
finishing channel selection.
Note: The measurement time depends on the
number of channels selected. Choosing
the correct channels to be measured
minimizes measurement time.
Mobile telecommunication companies
use 1310, 1550 nm for 2 G optic wavelengths and 1510, 1530, 1570 nm for
3 G optic wavelengths. Thus you should set up the user channel to (1310,
1510, 1530, 1550, 1570) in the menu.

When you press Graph/TEXT ( ) after performing a scan with the
USER SCAN button, you can see a user scan graph screen such as the
following.
OFFSET (VOLATILE)
The OFFSET function displays the
addition of set up dBm value and the
optic power value on the screen.
The user can increase reliability and
continuously maintain the measuring
instrument's own features and settings
by synchronizing the output value with
other measuring instruments using the
calibration function for each channel.
Note: As this value is saved in the volatile memory, it becomes zero after booting
and is not remembered if you turn the power off after set up.
