OTR 5444

12G Bi-directional Quad SDI/Fiber Transceiver

Datasheet Reference Manual


The OTR 5444 is a quad-channel bi-directional SDI/Fiber Transceiver module suitable for SDI video signals up to 12Gbit/s. It has four independent channels with automatic input clock rate and signal presence detection.

This module is ideally suited for demanding high-quality broadcast and professional video applications. It consists of four bi-directional 12G SDI high-density micro BNC electrical interfaces, which allows the user to set the direction of the signal flow. It also consists of four 12G SDI optical inputs and four 12G SDI optical outputs arranged in the optical TR slots.

Designed for the use in SERIES 5000, OTR 5444 is part of CardModules, which offers high quality, modularity and flexibility in a small form factor ideal for applications where space is at a premium. Like other 5000 series CardModules, this module is fully integrated into the LYNX APPolo Control system, which provides remote control, status monitoring and error reporting for the module.

Note: A maximum of 8 OTR 5444 HO cards can be installed in RFR 5018 rack frame. It CANNOT be fitted into slot 1 or 2 as it would block the RFR internal cross flow fan at the rear.
