Optical input and RF outputs
The operational optical input level of the receiver is -15...-5 dBm. In this region OLC is working and
provides fixed RF output levels. Ensure optical input level in this range. A direct optical connection
cannot be made between the transmitter and the receiver. Use appropriate optical attenuator.
