Connections
The SDI video input and output is connected to the corresponding 75
Ohm BNC connections provided (up to 3Gbit). The fiber connection is
made to the LC connector as indicated on the module. An example of a
LC connector shown below.
Operation
The OBD 1810 is a bidirectional transceiver which can send and receive
SDI data simultaneously through a single fiber link. The modules are
supplied as pairs, one “
Type A
” and one “
Type B
” and must be used as a
pair. This is a closed loop WDM application using 1310 and 1550nm
wavelengths.
Different video formats can be transmitted and received. Operation is
automatic, no user settings are required. For transmission, the SDI
video format is automatically detected, re-clocked and then
transmitted over the fiber optic link. The received fiber SDI format is
detected automatically, re-clocked and output as an electrical SDI
signal.
The OBD 1810 supports any SDI video signal from 270Mbit/s to 3Gbit/s.
Max distance is approx. 10km (6.2 miles). Data send and receive activity
is indicated by the LEDs located on the side of the module. The module
supports hot swapping and hot plugging of connections.
Power
The module requires a 12V DC power input and a LED is provided to
confirm 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
. OTT 1812 module shown, the OBD 1810 is identical in terms of mounting
Optional Mounting Bracket
The optional RFR 1001 mounting bracket can be used to permanently
mount the module on any flat surface or on 19” rack rails.
