OTR 1442

4K Fiber Transmission System 1350-1410nm

The OTR 1442 is a self contained fiber transmission kit for the transport of 4 discreet 3G-SDI signals (or 4K/12G uncompressed) 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 3G-SDI streams, or 4K up to 20km with no losses. Each 3G-SDI channel is fully independent. For 4K use cases, the signal is split over 4 separate 3G-SDI links (12G) and supports full 4K resolution at 60fps. The system can also be used for any combination of 3G-SDI signals, with a mix of formats and bit-rates if required. Each channel will automatically detect and reclock SDI bit rates of 270Mbit/s, 1.5Gbit/s and 3Gbit/s.

An expansion port is included for the connection of the OTR 1441 to add 4 more 3G-SDI channels (24Gbit/s over a single fiber), or add bi-directional Ethernet or Serial RS 232 data to the link.

LED status are provided for presence and power.
For convenient integration, the RFR 1018 ½ RU 19″ rack-mount tray supports the installation of up to four OTR modules.

Note: Internal CWDM optical multiplexing is utilized within the modules. This kit should be considered a self contained point to point solution and should not be integrated into external CWDM systems.
