Lynx Technik yellobrik OTX 1842 3Gbit SDI to Fiber Optic Transmitter (CWDM)

The OTX 1842 is a compact CWDM SDI to fiber optic transmitter designed to overcome the limitations associated with distributing uncompressed broadcast-quality video signals over long distances. When paired with a fiber optic to SDI receiver (e.g., yellobrik ORX 1802), it provides a cost-effective optical transmission system for signals up to 1080p60 (3Gbit/s), preserving full uncompressed quality. With 18 selectable wavelengths, the OTX 1842 ensures full CWDM compatibility.
