The optical fiber telephone achieves full-duplex
communication in single fiber by using WDM (wave-
length division multiplex) Technology. WDM is a
technology of transmitting with different wave-
length in single fiber.
The optical fiber telephone divides into Telephone A
and B. Telephone A and B have completely the same
operation except Telephone A modulates the signal
on 1310 mm wavelength, while Telephone B is on
1550 mm wavelength. They must be used in couple.
This telephone can use 2.5 mm traffic special head-
set and common 3.5 mm PC headset, but they can
not be used at the same time.

7. Communication Distance
Press the On/Off button so the device start
working. The power indication light is will turn on.
Press this button again and the telephone will shut
down.
Do not wear headsets before booting to avoid ear
damage caused by loud volume. The correct way is
turning down the volume after booting, then wear
the headset. After wearing the headset, adjust the
volume to clarity and without distortion.
According to the communication and line loss be-
tween two telephones, you must choose the appro-
priate communication distance. The optical fiber
telephone has two modes, remote communication
and near field communication. When the line loss is
more than 20 dB, you must use remote mode. The
maximum communication range of remote mode is
120 km. When one side is using optical fiber holder,
you must use remote mode too. The maximum com-
munication range is 60 km. When the line loss is less
than 20 dB, you must turn off remote mode, or will
cause howling and lead to no communication. The
maximum NFC distance is 60 km.
By pressing the Long button you can switch
between remote communication mode and near
field communication mode.

10. Low Power Indication
11. Charging
When the remaining battery power is less than 20%,
the low power indicator light will turn on.
If you use alkaline batteries, you will need to change
them with new ones. If you use rechargeable batter-
ies, you will need charge them at once.
The device has a charging function. When using
rechargeable batteries and turning up a low battery
indication, you should promptly shut down and
recharge it. Long time under voltage will shorten
the lifetime of the rechargeable batteries. Connect
the AC adapter to the device correctly, it can charge
Automatically. Besides, computer USB port can also
be used for charging. The battery remaining indica-
tor keeps flashing during charging. It will stop when
the charging is finished. The battery has finished the
fast recharge and can be used directly. If you do not
stop charging at this time, the device will continue
the trickle charge state, using small current to sup-
ply natural discharge. But this process is not more
than 48 hours. The device can still be used while
charging. But do not plug in the AC adapter when it
is not rechargeable batteries inside, or it will cause a
high temperature and combustion, even explosion.
