Python 3G
Multichannel Fiber Optic HD-SDI Transport System with CWDM Multiplexing

The Python 3G is your answer to lowering the cost of digital video distribution, simplifying your cable plant and eliminating all concerns about distance, interference and grounding. The Python 3G converts up to two groups of 8-channels of HD-SDI to fiber optic transport, all in a compact 1 RU frame. Select a transmitter and a receiver frame for eight or 16 channels, for example, in one direction. Select two transceiver frames for eight channels in each direction, from 19.4 Mb/s to 3 Gb/s.
