Area A – SDI/DATA OUT
Fig. 3-8: 4 SDI/DATA Output BNC Connectors
The Python 3G Receiver has four SDI/DATA Output BNC Connectors. All four Outputs
operate identically.
• On units without CWDM, the four outputs correspond to the four Fiber Optic inputs on
the back panel.
• For CWDM units, the four outputs are de-multiplexed from a single Fiber Optic input.
Each output has an LED monitor that indicates the following:
• Green: the Python 3G is receiving a signal for the indicated channel over the Fiber
Optic Cable and SDI signal is present.
• Alternating between Red and Green: a Fiber Optic connection is detected for the
indicated channel, but no SDI is present.
• Red: no optical connection is detected or the active optical signal has fallen below
-22 dBm
