OTX 1440

12G, 6G, 3G, HD SDI to Fiber Optic Transmitter (CWDM)

Datasheet Quickreference


The OTX 1440 is a compact CWDM SDI to fiber optic transmitter designed
to combat the restrictions involved with the distribution of uncompressed
broadcast quality video signals over long distances.
When paired with the fiber optic to SDI receiver (e.g. yellobrik ORX 1400) you
have a very cost-effective optical transmission / receiver system for signals up
to 4096x2160 / 60Hz (12Gbit/s), while preserving full uncompressed quality.
Select from up to 18 wavelengths for full CWDM compatibility.

Operation of the OTX 1440 is fully automatic. The SDI video format is detected,
reclocked and then transmitted over the fiber optic connection. A reclocked
electrical SDI output is also provided.
The O TX 1440 supports 12G, 6G, 3G and 1.5G SDI video standards.


• Supports 12G, 6G, 3G and 1.5G SDI video inputs
• 3Gbit Level A and Level B support (all formats)
• Auto reclocking 1.5Gbit / 3Gbit / 6Gbit / 12Gbit
• Reclocked SDI loop output
• multiple wavelengths available
• Error free optical transmission
• Simplex LC singlemode optical connection
• Supports hot swapping and hot plugging
