The Python 3G part number consists of three sections as described below:
Fig. 5-1: Python 3G part number
• A - The product designation – in this case PY3 stands for Python 3G
• B - Channel Card Options – the four letters correspond to the four available slots. If a
position has “0,” then the slot is empty. The available card options are listed below.
• C - Fiber I/O Options – typically varies between “ST” for ST connectors with straight-
through conversion for SDI/Data to or from Fiber Optic signal. “W” for units with
CWDM. The number indicates the number of fiber optic channels.
The I/O options are listed below.
