Lynx Technik yellobrik ORX 1702-1 ST Analog Sync / Video Fiber Optic Receiver

The ORX 1702-1 addresses the challenges of distributing broadcast-quality analog reference and composite video signals over extended distances. When paired with the OTX 1712-2 fiber optic transmitter, it forms a cost-effective optical transmission system for analog sync reference signals or NTSC/PAL composite video. This setup is particularly beneficial for maintaining correct synchronization between remote installations. Unlike basic analog-to-fiber conversion solutions, the ORX 1702-1 incorporates technology to maintain a high degree of sync and burst phase stability during fiber reception and analog conversion. The module receives an SDI signal (including reference and other relevant information) before converting it to an analog signal. Therefore, when used with 525 or 625 SDI video sources, it can directly convert the signal to an analog NTSC or PAL composite output. For example, if the 525 or 625 signal is received from an SDI video transmitter like the OTX 1812. The ORX 1702-1 provides two analog outputs and supports LC, ST, or SC single-mode fiber connections. An LC version suitable for multimode fiber is also available. :contentReference[oaicite:2]{index=2}
