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.
Python 3G Optical Measurement Display
The Python 3G optical signal strength display has characteristics for the Python 3G
Transmitter, Receiver, and Transceiver.
The Channel Select switch is a dual function switch and functions as follows:
• Flicking the switch to the right allows scrolling through the individual channels to
provide basic status on the signal.
• Flicking the switch to the left provides additional information about the current
channel.
Fig. 4-1: Flicking the CHAN SEL switch
Scroll through the signal channels by flicking the switch to the right. The system reports on
the installed SDI channels and the installed fiber channels being transmitted by the unit.
In a 4 x4 Transceiver, the CHAN SEL switch will display the four Transmit channels first
followed by the four Receive Channels.
After the last channel, the display will show the current ambient temperature within the
unit chassis in degress Celsius.
After each flick, the display will indicate the monitored channel such as Tx01 or Tx02 (for the
Transmitter and Transciever) and Rx01 or Rx02 (for the Receiver). For each TX/RX channel,
you can flick the switch to the left to display Technical Information about the channel.
As you scroll through the channels, one of three conditions will be displayed for the
Received channels:
• No fiber link for a channel
• Existing optical link but with no active SDI Data
• Active usable optical link with SDI Data (Available only for Receive channels)
