LynxTechnik yellobrik 3Gbit SDI To Fiber Optic Transmitter (yellobrik Module Only,Requires CWDM SFP)

Product Code LYOTX1842
Manufacturer LynxTechnik

Request more information or contact us now for purchasing information.


The OTX 1842 is a compact CWDM SDI to fibre optic transmitter designed to combat the restrictions involved with the distribution of uncompressed broadcast quality video signals over long distances.

When paired with the fibre optic to SDI receiver (e.g. yellobrik ORX 1802) you have a very cost effective optical transmission / receiver system for signals up to 1080p60 (3Gbit/s), while preserving full uncompressed quality. Select from 18 wavelengths for full CWDM compatibility.

The OTX 1842 will auto-detect any connected video signal from 270Mbit/s to 3Gbit/s according to SMPTE 424M, SMPTE 292M and SMPTE 259M standards, as well as DVB-ASI.

The module does not include a Fibre SFP sub module, an option MUST be selected from the table shown below.
