Connections
The SDI video input is connected to the 75 Ohm BNC connections (up to
3G). The ber connection is LC Duplex SMF (Singlemode). An example
of the LC connector shown below (ber Optic cable and LC connectors
are not supplied).
Use the included dust plug to protect the optical connection from dust.
Operation
The OTT 1812-1 supports any SDI video signal from 270Mbit/s to 3Gbit/s.
Maximum distance is 10km (6.2 miles). Data transmission activity is
indicated by the TX LEDs on the side of the module.
T he module has two identical (and fully independent) channels.
Operation is fully automatic. For reception, the received SDI format is
detected automatically and provided on the SDI input connection (up
to 3G). The module supports hot swapping and hot plugging of
connections. No user settings are provided for this module.
Note: If TX LED is OFF this indicates no SDI input is present, or the input signal is
not valid.
Power
The module requires a clean 12V DC (7-24V DC) power source. An LED is
provided to conrm power is connected. A 12V DC power supply is
included with the module. If you are applying your own power source,
please provide a clean 7-24V DC power source. Power consumption
information can be found in the technical specications table.
Note: OTT 1812-1 is identical in terms of mounting and securing
Note: The module is designed for use with SMF
(Singlemode) ber cable. While it is possible to
use Multimode cable, performance (distance) is
greatly degraded and not guaranteed.
Optional Mounting Brackets
The optional RFR 1001 mounting brackets can be
used to permanently mount the modules on any
at surface or on 19‘‘ rack rails.
Power Lead Strain Relief
The modules have 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.
The optional RFR 1000-1 rack mount can be used to permanently
mount up to 14 yellobrik modules. In addition, the RFR 1000-1 can
provide full power redundancy for all mounted yellobriks.
