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 1712 is a compact analogue sync or NTSC/PAL composite video to fibre optic transmitter. This device is specifically designed to combat the restrictions involved with the distribution of broadcast quality analogue reference and composite video signals over long distances.

When paired with the fibre optic receiver ORX 1702 you have a very cost effective optical transmission system for analogue sync reference signals or NTSC/PAL composite video. This device is particularly useful for reference sync distribution between remote installations to maintain correct synchronization.

Unlike other very basic analogue to fibre conversion solutions, the OTX 1712 incorporates technology to maintain a very high degree of sync and burst phase stability during the conversion and fibre transmission.

The module converts the NTSC/PAL video signal to an SDI signal (including reference and other relevant information) before it is converted to fibre. Therefore when the OTX 1712 is used for NTSC or PAL video sources it is possible to convert the fibre signal directly to SDI if required using an SDI receiver (e.g. ORX 1802).

The OTX 1712 provides a passive loop output and support for LC, ST or SC singlemode fibre connections. An LC version suitable for multimode fibre is also available.
