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

The OTX 1812 is a compact SDI to fiber optic transmitter designed to overcome the limitations of distributing uncompressed broadcast-quality video signals over long distances. When paired with a fiber optic to SDI receiver (e.g., yellobrik ORX 1802), it provides a cost-effective optical transmission system for signals up to 1080p60 (3Gbit/s), preserving full uncompressed quality.
