Connections
The SDI video input is connected to the 75 Ohm BNC connections (up
to 3Gbit). 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)
Operation
The module supports CWDM and has two independent channels, each
with a dierent wavelength (selected at time of order, installed
wavelengths are indicated with a white label on top of the module).
Operation is fully automatic. The SDI Input video rates are automatically
detected, reclocked and transmitted over the optical connections.
The OTT 1842 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.
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
conrm 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.
*Note
The module is a CWDM device and can only be
used with SMF (Singlemode ber). Multimode
ber is not supported.
Optional Mounting Bracket
The optional RFR 1001 mounting bracket can be used to permanently
mount the module on any at surface or on 19” rack rails.
