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.
Connections
The SDI video input and output is connected to the corresponding 75
Ohm BNC connections provided (up to 3Gbit). The ber connections
are made to the ber SFP sub module as indicated on the module.
Both versions (OTR 1810 - Singlemode, and OTR 1810 MM - Multimode)
use a dual LC simplex connection. Please enure the ber cable used is
of the correct type for the module. (Singlmode or Multimode)
The module ber connection is supplied with a rubber plug installed,
this is to prevent dust contamination. Please retain the plug and use if
the cables are ever disconnected from the module. An example of a
LC connector is shown below:
Operation
The OTR 1810 combines an independent ber optic transmitter and
receiver into a single package. Dierent SDI video formats and
standards can be transmitted and received. Operation of the receiver
and transmitter is automatic. For transmission, the Input video format
is automatically detected and the video signal is reclocked and then
transmitted over the ber optic connection. For reception, the received
SDI format is detected automatically and provided on the SDI output
connection (up to 3Gbit)
The module supports hot swapping and hot plugging of connections.
No user settings are provided for this module.
Distance
Two versions of the module are available. Each version is supplied with
a dierent SFP sub module :
OTR 1810 - This is designed for use with Singlemode cable and has a
max distance of approx 10km (6.2 miles) for SDI signals up to 3Gbit/s
OTR 1810 MM - This is designed for use with Multimode cable and has
a max distance of approx 300m (984 feet) for SDI signals up to 3Gbit/s
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 1.6W
