OTR 1441

4K Fiber Transmission System

Datasheet Quickreference


The OTR 1441 is a self contained fiber transmission kit for the transport of 4 x SDI signals (12G uncompressed) over a single fiber link for distances up to 20km (12miles). The kit includes the fiber transmitter, fiber receiver and power supplies. This is an ideal solution for the transmission of multiple uncompressed SDI streams over long distances with zero losses.  
Each SDI channel is fully independent. For 4K use the signal is split over 4 separate 3G SDI links (12G) and supports 4K resolution at 60fps. The system can also be used for any combination of SDI signals each with a different format and bit-rate if required. Each channel will automatically detect and reclock SDI bit rates of 270Mbit, 1.48Gbit and 2.97Gbit.  
LED Indicators are provided for channel presence and power. An optional 19” rack mount tray is available which can accommodate up to 4 modules.
