Connections
The SDI video input and output is connected to the corresponding 75
Ohm BNC connections provided (up to 3G).
The ber connection is
made with a duplex LC connector as indicated on the module. An
example of a duplex LC connector 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 OTR 1840-1 combines a CWDM ber optic transmitter and receiver
into a single package. Dierent SDI video formats and standards up to
3G can be transmitted and received.
Data transmission/reception
activity is indicated by the TX/RX LEDs on the side of the module.
Operation is fully automatic. The ber input video rate is automatically
detected, reclocked and provided on the BNC output connector. No
user settings are provided for this module. The module supports hot
swapping and hot plugging of connections.
Note: If TX LED is OFF this indicates no SDI input is present, or the input signal is
not valid. I
f RX LED is OFF this indicates no signal is present, signal is too weak or
not a valid input.
Note: OTR 1840-1 is identical in terms of mounting and securing
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.
Note: The module is designed for use with SMF
(Singlemode) ber cable.
Power
The module requires a clean 12V DC (7-24V DC) power source. An LED is
provided to conrm 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 specications table.
