Request more information or contact us now for purchasing information.


The OTT 1842 is a compact CWDM dual channel SDI to fibre optic transmitter designed to combat the restrictions involved with the distribution of uncompressed broadcast quality video signals over long distances. 18 wavelength choices are provided.

When combined with the dual channel fibre optic to SDI receiver modules ORR 1802, and the OCM 1891/1892 CWDM multiplexers you have a very cost effective CWDM fibre system with up to 18 signals in a single fibre link.

The OTT 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.
