OTT 1442

Dual Channel 12G 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 12G 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 270M / 1.5G / 3G and 12G SDI source prior to optical transmission. The module is fully  compatible with 3G Level A and Level B formats.

This yellobrik had a major hardware update. If your yellobrik has no usb port on it's length side please visit the yellobrik documents in our downloads section for the datasheet and quick reference.
