OTT 1442

Dual Channel 12Gbit SDI to Fiber Transmitter (CWDM)

Datasheet Quickreference


The OTT 1442 is a compact CWDM dual channel SDI to fiber optic transmitter designed to combat the restrictions involved with the distribution of uncompressed broadcast quality video signals over long distances. Nine pairs of wavelength choices are provided.
When paired with a dual channel 12Gbit fiber optic to SDI receiver (e.g yellobrik ORR 1402) you have a  very cost-effective optical transmission / receiver system for two independent signals up to 12Gbit/s (4096x2160 @ 60Hz), while preserving full uncompressed quality.
The OTT 1442 has two completely independent channels and each will auto-detect and re-clock any 270Mbit / 1.5Gbit / 3Gbit and 12Gbit SDI source prior to optical transmission. The module is fully  compatible with 3Gbit Level A and Level B formats.


  • Dual Channel
  • Supports SDI video inputs up to 12Gbit/s (2160p60)
  • 3Gbit Level A and Level B support (all formats)
  • Auto reclocking 270Mbit / 1.5Gbit / 3Gbit / 12Gbit
  • Error free optical transmission
  • Up to 10km (6.2 miles) @ 12Gbit/s
  • Duplex LC/PC single mode optical connections
  • Supports hot swapping and hot plugging
