Connections
The SDI input and reclocked SDI output are connected to the 75 Ohm
BNC connections. The ber connection is made to the singlemode LC
connector as indicated on the module. An example of the LC connector
is shown below.
Use the included dust plug to protect the optical connection from dust.
18 wavelengths are available to choose from when ordering the
module.
Operation
The OTX 1842 supports all SDI formats from 270Mbit/s to 3Gbit/s as well
as DVB/ASI. Data transmission activity is indicated by the TX LED on the
side of the module.
Operation if fully automatic. The SDI input video format is automatically
detected and the video signal is reclocked and then transmitted over
the optical connection and the loop out.
There are no user adjustments
for the module. The module supports hot swapping and hot plugging
of all connections.
Note: If TX LED is OFF this indicates no SDI input is present, or the input signal is
not valid.
Note: OTX 1842 is identical in terms of mounting and securing
Note: The module is designed for use with SMF
(Singlemode) ber cable.
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.
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.
