While compact in design, the yellobrik OTX 1842 3Gbit SDI to Fiber Optic Transmitter is a powerful CWDM SDI to fiber optic transmitter engineered to overcome the limitations associated with transmitting uncompressed, broadcast-quality video signals over extensive distances. This device, when combined with a fiber optic to SDI receiver such as the yellobrik ORX 1802, forms an incredibly cost-effective optical transmission/receiver system, capable of handling signals up to 1080p60 (3Gbit/s) without compromising on the quality of the uncompressed video.
The OTX 1842 stands out with its ability to select from 18 different wavelengths, ensuring full CWDM compatibility. It also features an auto-detect and re-clock function for any 270Mbit / 1.5Gbit and 3Gbit SDI source prior to optical transmission, enhancing the reliability and efficiency of the signal transmission. Moreover, this module is fully compatible with 3Gbit Level A and Level B formats, making it a versatile addition to any professional video production setup.
In summary, the yellobrik OTX 1842 3Gbit SDI to Fiber Optic Transmitter is a compact yet robust solution for long-distance, high-quality video signal transmission, offering full CWDM compatibility and a range of advanced features to ensure optimal performance.
