Using the UHD Digital Forecast Bridge M_OTR 3GT/R is straightforward. First, connect it to a 12V DC power source within the 7 - 17V range. Then, link your SDI devices to the transmitter and receiver as needed. You can use a single - core LC cable for dual - channel transmission. When it comes to data rate, keep in mind it can handle a max of 600Mhz. For video, it supports many popular HD and FHD formats. As for the transmission distance, you can expect up to 10km in LC single - mode and 100m in OM3 LC multi - mode. Be careful not to expose the device to humidity levels above 95% as it may cause damage. To maintain it, keep it clean and free from dust. If there are any issues, check the power supply and cable connections first.
