The CQS 1441 is a compact solution to bridge between 4K UHD quad link 2SI devices and single link 12G SDI devices. The module can be configured to convert to or from Quad link 2SI.

The module is suitable for all SMPTE standard signals from 1.5Gbit/s to 12Gbit/s (SMPTE 292M, 424M, 2081 and 2082)

Note. This module DOES NOT support SQD or “Square Division” quad conversions, only 2SI

Conversion modes:

  • 12G SDI single link to 4 x 3G Quad link (2SI)
  • 4 x 3G Quad link (2SI) to 12G SDI single link
  • 6G SDI single link to 4 x 1.5G SDI
  • 4 x 1.5G SDI to 6G SDI single link

With the distance limitations of 12G SDI electrical connections, the CQS 1441 is equipped with an integrated SFP fiber port which can accept a number of 12G fiber options depending on the specific application.
