Lynx Technik yellobrik OTX 1812-SC 3G SDI to Fiber Optic Transmitter

The OTX 1812-SC addresses the challenges of distributing uncompressed broadcast-quality video signals over extended distances. By converting SDI signals to optical, it enables seamless transmission without compromising quality. When paired with a compatible fiber optic to SDI receiver, such as the yellobrik ORX 1802, it forms a cost-effective solution for transmitting signals up to 1080p60 (3Gbit/s). The module auto-detects and reclocks any 270Mbit/s, 1.5Gbit/s, and 3Gbit/s SDI source prior to optical transmission and is fully compatible with 3G Level A and Level B formats. :contentReference[oaicite:4]{index=4}
