  • Duplex LC/PC single mode optical connections
  • Supports hot swapping and hot plugging

** Distance is an approximation. Actual distances achieved can be longer or shorter depending on the type of fiber cable and accumulated optical losses in the fiber link. Determine link losses and perform optical budget calculations to ensure correct operation.


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 (4096×2160 @ 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.

Note: The module DOES NOT INCLUDE the fiber SFP, When ordering please specify an SFP option in the wavelengths required
