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).
The OTT 1842-1 basic module has no pre-determined ber SFP sub
module included. Instead, when ordering the CWDM module the
customer selects one of the 18 available wavelengths when ordering
the module. If you need to check the wavelength of an SFP, a sticker
with the type description can be found on every LYNX-Technik SFP
when removing it from the yellobrik module.
Operation
The OTT 1842-1 supports any SDI video signal from 270Mbit/s to
3Gbit/s. Maximum distance is 40 km (24.8 miles). Data transmission
activity is indicated by the TX LEDs on the side of the module.
The module has two independent channels. It supports CWDM with the
wavelength selected at the time of order.
Operation is fully automatic. The SDI Input video rates are automatically
detected, reclocked and transmitted over the optical connections.
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.
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.
Note: OTT 1842-1 is identical in terms of mounting and securing
Note: The module is designed for use
with SMF (Singlemode) ber cable.
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.
