It is a compact analog sync or NTSC/PAL composite video to fiber optic receiver. 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 optic transmitter OTX 1712 you have 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 ORX 1702 incorporates technology to maintain a very high degree of sync and burst phase stability during the fiber reception and analog conversion.
