OTX 1812

3G-SDI to Fiber Transmitter

The OTX 1812 is a compact 3G-SDI to fiber transmitter designed to combat the restrictions involved with the distribution of uncompressed broadcast quality video signals over long distances. When paired with a fiber to 3G-SDI receiver (e.g. yellobrik ORX 1802) it becomes a cost effective optical transmission / receiver system for 3G-SDI signals up to 1080p60.

The OTX 1812 provides a looping 3G-SDI input and support for LC, ST or SC single-mode fiber connections as well as LC version suitable for multi-mode fiber.

The OTX 1812 will auto-detect and re-clock any 270Mbit/s, 3G/1.5G/SD-SDI source prior to optical transmission. The module is fully compatible with 3G Level A and Level B formats.
