forward direct modulation transmitter module – Laser Parameters:
forward direct modulation transmitter module – Laser Parameters:
You may view the laser parameters including output power, laser bias current, RF
input level, output wavelength, laser type, laser temperature, and TEC current.
For the display of RF input level, there are two situations:
1. If the RF input signal contains analog signal and digital signal, RF input level
input level, output wavelength, laser type, laser temperature, and TEC current.
For the display of RF input level, there are two situations:
1. If the RF input signal contains analog signal and digital signal, RF input level
displays the average level of the single channel analog signal at the broadcast
RF input port. Forward transmitter detects the total power of RF signal. The
average level of single channel digital signal is calculated according to the
actual channel number and the D-value of analog and digital channels as set
by the customer.
For example: Input 30 channels in the analog signal, 15 dBmV/channel at the
broadcast RF input port, 85 channels in the digital signal, 9 dBmV/channel at
the broadcast RF input port, the D-value between digital signal and analog
signal is set to 6 dB, RF input level displays 15 dBmV, the digital signal level
is the displayed RF input level minus 6 dB.
