The OTX 1712-2 is a compact analog sync or NTSC/PAL composite video to fiber transmitter. This device is specifically designed to combat the restrictions involved with the distribution of broadcast quality analog reference and composite video signals over long distances. When paired with the fiber receiver ORX 1702-1 it becomes a very cost effective optical transmission system for analog 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 analog to fiber conversion solutions, the OTX 1712-2 incorporates technology to maintain a very high degree of sync and burst phase stability during the conversion and fiber transmission.

The module converts the NTSC/PAL video signal to an SDI signal (including reference and other relevant information) before it is converted to fiber. Therefore when the OTX 1712-2 is used for NTSC or PAL video sources it is possible to convert the fiber signal directly to SDI if required using an SDI receiver (e.g. ORX 1802).

The OTX 1712-2 provides a passive SDI loop output. It can be equipped with LC, ST and SC 1310 nm single-wavelength fiber SFP as well as Multi-mode 850 nm and CWDM SFP. CWDM fiber SFPs enable much longer distances and must be purchased separately with the required wavelength. Like all yellobrik modules, it is compatible with the RFR 1200 rack frame, which provides power redundancy.
