OTR 5840

Dual SDI to Fiber Optic Transceiver

Datasheet Reference Manual


The OTR 5840 is a flexible dual channel SDI electrical to optical transceiver suitable for SDI/ASI-DVB video signals up to 3Gbit/s. Each channel has automatic input clock rate and signal presence detection with selectable signal reclocking. This module is ideally suited for demanding digital multi-format broadcast and professional applications.

Two input channels can be switched between optical or electrical inputs. In non-reclocked mode the module will transparently pass any data between 15Mbit/s and 3Gbit/s. Support for ASI/DVB and SMPTE 310 signals is also provided.

Select from 18 transmitter wavelengths for CWDM applications, or select dual 1310nm transmitter wavelengths for non CWDM applications.

An integral 4x4 signal router can be utilized to change 1/O channel mapping when using the LYNX control system.

Up to 10 modules (or 20 fiber RX and 20 TX channels) can be supported in a standard LYNX 2RU rack frame. The Fiber SFP sub-modules are secured on the backplane allowing for module removal and hot swapping without removing any modules rear I/O fiber connections.

NOTE: This module has advanced features and the use of APPolo control system is recommended. If installed in a RFR 5012 chassis please make sure a rack controller (RCT 5023 G) is installed in the rack.
