Connections
The SDI video input is connected to the 75 Ohm BNC connections (up
to 3Gbit). The fiber connection is LC Duplex SMF (Singlemode). An
example of the LC connector shown below (fiber Optic cable and LC
connectors are not supplied)
Operation
The module has two identical (and fully independent) channels.
Operation is fully automatic. The SDI Input video rates are automatically
detected, reclocked and transmitted over the optical connections.
The OTT 1812 supports any SDI video signal from 270Mbit/s to 3Gbit/s.
Maximum distance is 10 km (6.2 miles)*. Data transmission activity is
indicated by the TX LEDs on the side of the module.
Note.
If TX LED is OFF this indicates no SDI input is present, or not a
valid input.
The module supports hot swapping and hot plugging of connections.
No user settings are provided for this module.
Power
The module requires a 12V DC power input and a LED is provided to
confirm power is connected. A power supply is provided, but if
applying your own power, please provide a clean 12V DC power source.
Module power consumption is approx 250mA (2.8VA)
Power Lead Strain Relief
The module has a small hole in the case located above the power
connection to prevent the power lead being accidentally pulled out.
Use the supplied tie-wrap and secure the lead as shown below.
Optional Mounting Bracket
The optional RFR 1001 mounting bracket can be used to permanently
mount the module on any flat surface or on 19” rack rails.

Note
The module is designed for use with SMF
(Singlemode) fiber cable. While it is possible to
use Multimode cable, performance (distance) is
greatly degraded and not guaranteed
