2.2 TWIN mode – wavelength detection with FHP2 (optical power meter):
Continuity and attenuation measurements can be carried out in combination with the
FHP2 power meter by inserting the FHS2 laser source on one side and measuring the
level with the FHP2 level meter on the other side.
TWIN mode is a special mode that allows the FHS2 transmitter to use a log to relay
control commands to the FHP2 receiver.
The FHS2 laser source can automatically switch over the FHP2 optical level meter to the
right wavelength in TWIN mode. The TWIN function on the FHS2 must also be switched
on for this. In this mode, a switchover from 1310 nm to 1550 nm and back on the FHS2
laser source automatically switches over the FHP2 level meter as well, without requiring
the user to operate the level meter on site.
Pressing the TWIN key switches this function on or off.
2.3 CW/Hz button
Along with CW (constant wave), modulated signals can also be relayed from the FHS2
transmitter to the FHP2 level meter, which are then decrypted and displayed in the FHP2
level meter to simulate signal transport or to identify the cable. Using the CW/Hz button,
the transmitter can relay
no (= constant optical signal)
a 270 Hz
a 1 kHz or
a 2 kHz
signal.
