LynxTechnik yellobrik 3Gbit SDI To Fibre Optic Transmitter With Looped SDI (Fibre ST Connectors)

Product Code LYOTX1812ST
Manufacturer LynxTechnik

Request more information or contact us now for purchasing information.


Using the same basic module we provide four versions suitable for LC, ST or SC singlemode fibre connections, as well as a version for multimode fibre. Each version has a different SFP installed.

The OTX 1812 is a compact 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.

The OTX 1812 provides a looping SDI input and support for LC, ST or SC singlemode fibre connections as well as an LC version suitable for multimode fibre.

The OTX 1812 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.
