Installation instructions
Read the product description and safety instruction first.
Fiber installation should be done very carefully. Bending radius of fibers must be not less 25 mm. All optical connectors and
adaptors should be cleaned before connecting them. Power on the receiver after all cables have been connected correctly.
Powering of receiver
Operating and adjusting
Optical Level Control (OLC) is active at optical input power -6 .. 0 dBm. RF level remains constant while optical input power
fluctuates in range of -6 .. 0 dBm. Out of this range receiver continues to operate though OLC is disabled.
The receiver owns optical input power indicator formed from 3 LED. Note the table below for detailed description.
