Lynx Technik yellobrik OTT 1812-1 Dual 3G SDI to Fiber Optic Transmitter

The OTT 1812-1 addresses the challenges associated with distributing uncompressed video signals over extended distances. By converting SDI signals to optical, it enables seamless transmission without compromising quality. Each of the two independent channels auto-detects and reclocks any 270Mbit/s, 1.5Gbit/s, or 3Gbit/s SDI source prior to optical transmission, ensuring signal integrity. The module is fully compatible with 3G Level A and Level B formats, making it versatile for various broadcast applications. When paired with the dual-channel fiber optic to SDI receiver (e.g., yellobrik ORR 1802-2), it offers a cost-effective solution for high-quality signal transmission. :contentReference[oaicite:4]{index=4}
