The OTR 5444 4-channel 12G-SDI fiber transceiver is a four-channel, bi-directional 12G-SDI to fiber module designed for video signals up to 4096×2160p at 60 Hz. Each channel operates independently and features automatic input clock detection and signal presence monitoring.

The card provides four bi-directional 12G-SDI micro BNC interfaces, along with four SFP Transceivers allowing up to four fiber receivers and four fiber transmitters. The latest firmware update enables optical signals to be reclocked and looped to their respective fiber transmitter.

Designed for demanding broadcast environments, the card delivers reliable high-quality signal transport in a compact, modular form factor, making it well suited for space-constrained installations. As part of the Series 5000 platform, the OTR 5444 integrates seamlessly with Lynx Centraal for remote control, status monitoring, and error reporting.

Note: Up to eight OTR 5444 HO cards can be installed in the RFR 5018 rack frame. The module must not be placed in slots 1 or 2, as this would obstruct the rack’s internal rear-mounted airflow fan.
