OTR 1441
Quad 3G SDI Fiber Optic Transmission System
The OTR 1441 is a self contained fiber transmission kit for the transport of 4 discreet SDI signals over a single fiber link. The kit includes the fiber transmitter, fiber receiver and power supplies. This is an ideal solution for the transmission of multiple uncompressed SDI streams up to 20km with zero losses.
Each SDI channel is fully independent. For 4K use the signal is split over 4 separate 3G SDI links. The system can also be used for any combination of SDI signals, with a mix of formats and bit-rates if required. Each channel will automatically detect and re-clock SDI bit rates of 270Mbit, 1.48Gbit and 2.97Gbit.
An expansion port is included for the connection of the OTR 1442 to add 4 more SDI channels (for 8 channels over a single fiber)
LED Indicators are provided for channel presence and power. An optional 19” rack mount tray is available which can accommodate up to 4 modules (RFR 1018).
