OTT 1442
Dual Channel 12G SDI Fiber Transmitter (CWDM)
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 / 6Gbit /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
