Lynx Technik yellobrik OTR 1442-SC 4k Fiber Transmission System

The OTR 1442 is a comprehensive fiber transmission kit designed to transport four discrete SDI signals, or a single 4K/12G uncompressed signal, over a single fiber link. This solution is ideal for transmitting multiple uncompressed SDI streams or 4K content up to 20 km (12 miles) without any loss. Each SDI channel operates independently, supporting resolutions up to 1080p at 60Hz. For 4K applications, the signal is divided over four separate 3G-SDI links, maintaining full 4K resolution at 60fps. The system also accommodates various combinations of SDI signals, allowing for mixed formats and bit rates as needed. Each channel automatically detects and reclocks SDI bit rates of 270Mbit/s, 1.5Gbit/s, and 3Gbit/s.
