Page 42: Fiber Optical Channel Monitoring
Python 3G Operation Fiber Optical Channel Monitoring Fiber Optical Channel Monitoring The Python 3G provides direct digital readout of the Fiber Optic Link signal strength for signals received at the unit. This readout is presented in units of dBm. It is useful to understand both the dB or decibel and the dBm or decibel referenced to one milliwatt. -
Page 43: Using The Python 3G Optical Measurement Display
Python 3G User Guide Using the Python 3G Optical Measurement Display The optical measurement functionality is similar across all three types of Python 3G. A transceiver, transmitter, and receiver work identically with one exception. The system reports fiber optical strength only for fiber optic signals received at a unit. Transmission strength is not measured. -
