openGear® INTRODUCTION
Developed by Ross Video, open ear® is a standard where various manufacturers can design their equipment to fit
a common frame allowing the end user to mix and match the various open ear® cards available in the market
place together in one frame. This allows a single frame to be used instead of multiple different vendor’s frames
that each would otherwise be using their own proprietary standard.
A simple to use monitoring and control software called DashBoard™ is a free program downloadable from the
open ear® website (www.opengear.tv) that allows the user to remotely monitor and control an open ear® type
card fitted within an open ear® frame that meets the open ear® standard for DashBoard™ control. A link is also
supplied via the I.R.T. Communications website (www.irtcommunications.com) under the open ear® navigation
section.
I.R.T. Communications’ open ear® cards are designed to meet the open ear® standard for mounting within the
open ear® O 3-FR frame and its earlier version DFR-8300 frame, and is fully compliant with DashBoard™ control.
The open ear® frame manual, DashBoard™ control software and information regarding the frame’s power
supplies, controller card and frame accessories are available for download at the open ear® website.
The term open ear® is a registered trade mark of Ross Video Limited.
DashBoard software Control™ is a trade mark of Ross Video Limited.

GENERA DESCRIPTION
The IRT-6630-DDT and IRT-6630-DDR are transmit and receive modules designed principally for use as a serial data
fibre optic transmission link for 3 -SDI, HD-SDI or SD-SDI applications conforming to SMPTE standards 424M, 292M
and 259M-C using 9/125 μm single mode fibre. This enables the use of space saving fibre optic cable for reliable
transmission of digital video signals over lengths greater than can be achieved with coaxial cable.
In addition, the link may be used for ASI transport streams for use with MPE compressed video streams or other
270 Mb/s type data.
The transmitter features automatic input cable equalisation. A “keep link alive” signal is available to maintain
optical link operation when no electrical input is present.
Two inputs are provided with automatic changeover to input 2 on loss of input 1 for input signal redundancy.
The receiver uses an APD detector with signal conditioning and reclocking circuits. The data rate is automatically
set to match the 3 -SDI, HD-SDI or SD-SDI/ASI rates dependent on the actual input data rate to the transmitter.
The IRT-6630-DDT and IRT-6630-DDR are designed to fit the open ear® standard 2RU frames which allow a
mixture of cards from various manufacturers to be mounted within the same frame.
The DashBoard™ control software is available as a free download.
Standard features:
• Transports 3G-SDI, HD-SDI, SD-SDI or ASI signal rates .
• Path lengths up to 30 dB

INSTA ATION
Pre-installation:
Handling:
This equipment may contain or be connected to static sensitive devices and proper static free handling precautions
should be observed.
Where individual circuit cards are stored, they should be placed in antistatic bags. Proper antistatic procedures
should be followed when inserting or removing cards from these bags.
Installation in openGear® frame:
See details in separate manual downloadable from the open ear® website (www.opengear.tv).
Signal Connections:
IRT-6630-DDT:
The default setting of the IRT-6630-DDT is to automatically operate at either 2.97 Gb/s 3G-SDI, 1.485 Gb/s HD-SDI or
270 Mb/s SD-SDI / ASI signals and do not require any adjustment prior to use, with the exception of DIP switch
options described in the Configuration section of this manual that also allow SD only, HD/SD only or reclocker
bypass modes of operation. Note that in order for DIP switch settings to have any effect, DIP switch SW1-7 must be
in the OFF position, else all configuration settings are made via DashBoard™ or SNMP software control.
The serial digital signal connections are made to the BNC connectors on the rear panel. IN 1 is the primary input to
the IRT-6630-DDT. With DIP switch SW1-6 OFF, IN 2 becomes the secondary input and will switch in automatically
on loss of a valid input to IN1. Upon restoration of a valid signal to the IN 1 port, the optical transmitter
automatically restores back to the signal on the IN 1 port. With SW1-6 ON, automatic changeover is disabled and
although IN 2 is still monitored it is essentially ignored as far as the laser output is concerned.
With DIP switch SW1-3 OFF, the OUT 1 and OUT 2 BNC connectors act as monitor ports for the transmitter output.
It will monitor either the IN 1 or IN 2 input depending on which input is actually feeding the optical laser.
With DIP switch SW1-3 ON, the OUT 1 and OUT 2 BNC connectors act as respective monitor ports for both the IN 1
and IN 2 inputs. OUT 1 monitors the IN 1 port and OUT 2 monitors the IN 2 port.
IRT-6630-DDR:
The default setting of the IRT-6630-DDR is to automatically operate at either 2.97 Gb/s 3G-SDI, 1.485 Gb/s HD-SDI or
270 Mb/s SD-SDI / ASI signals and do not require any adjustment prior to use, with the exception of DIP switch
options described in the Configuration section of this manual that also allow SD only, HD/SD only or reclocker
bypass modes of operation. Note that in order for DIP switch settings to have any effect, DIP switch SW1-7 must be
in the OFF position, else all configuration settings are made via DashBoard™ or SNMP software control.
The serial digital signal connections are made to the BNC connectors on the rear panel. Two identical signal
outputs, OUT 1 and OUT 2, are provided. BNC connectors IN 1 and IN 2 are not used.
Fibre Optic Connection:
The standard optical connectors of the IRT-6630-DDT & IRT-6630-DDR are SC/PC type and are attached directly to
the main module PCB, NOT the rear connector assembly.
When installing the optical fibre sufficient slack should be allowed for the module to be withdrawn with the optical
fibre attached until the connector is clear of the frame and can be disconnected. If this is not done, the module will
not be able to be removed without first disconnecting the optical fibre at the rear. Attempting to remove the
module without first disconnecting the fibre may result in damage to the fibre and / or the module.
Note that for path lengths ≤ 9 dB for APD detectors, or ≤ 3 dB for PIN detectors, an optical attenuator must be
used to avoid over driving the IRT-6630-DDR detector.

Rear Assembly ayouts
The IRT-6630-DDT and IRT-6630-DDR share the same type of rear assembly. Consequently the IN 1 and IN 2 BNC
connectors on the IRT-6630-DDR are not used.
The OUT 1 and OUT 2 BNC connectors of the IRT-6630-DDT are used for signal monitoring, whether monitoring the
input signals IN 1 and IN 2 or the signal that is being transmitted via the optical output is dependent upon the
SW1-3 DIP switch setting as described in the Configuration section of this manual.

OPERATION
The IRT-6630-DDT and IRT-6630-DDR is a single channel 3 /HD/SD-SDI/ASI optical link.
A single SC/PC style of connector (standard) on the rear of the card provides the optical transmit and optical receive
fibre connection on the IRT-6630-DDT and IRT-6630-DDR respectively.
The default settings of both the IRT-6630-DDT and IRT-6630-DDR are automatically set to operate at either 2.97 Gb/s
3G-SDI, 1.485 Gb/s HD-SDI or 270 Mb/s SD-SDI (or ASI) and do not require any adjustments prior to use. However,
either DIP switch or DashBoard™ settings also allow the unit to be set for SD only, SD/HD only or reclocker bypass
modes.
A 2.97 b/s 3 -SDI signal, 1.485 b/s HD-SDI signal or a 270 Mb/s type of signal, such as ASI or SDI, is connected to
a 75 Ω BNC connector (IN 1) of the rear assembly of the IRT-6630-DDT fibre optic transmitter. Front panel LEDs
indicates the presence and data rate of a valid input signal.
A secondary input (IN 2) can be automatically switched to the optical output (if enabled) on loss of a valid input
signal to IN 1. On resumption of a valid signal to IN 1 the optical transmitter automatically switches back to the IN 1
input. The secondary input rate LED will flash to indicate its presence and rate. Even if the automatic change-over
function is disabled, rendering the secondary input redundant, the secondary input rate LED will still indicate the
presence of a secondary input.
If the laser is set for permanent operation, on loss of an input signal, a 54MHz oscillator is switched into the optical
output so that the optical receiver still recognizes the optical link as being valid. This 54MHz signal does not affect
the signal reclocking detect circuitry of the receiver section, which is used in signal presence/alarm indication on
detection or absence of a valid 3 , HD or SD signal.
Single mode optical cable is directly connected to the module at the rear of the unit. Likewise the fibre connection
at the far end of the fibre optic cable is directly connected to the rear of the receiver.
The system will operate with an optical path loss from 9dB to a maximum of 27dB (for 3 -SDI signals. Typically
>30dB for HD/SD-SDI signals) when the IRT-6630-DDR is fitted with an APD detector, and from 3dB to a maximum
of 18dB when fitted with a PIN detector. A flashing green LED indicator on the front edge indicates when the
optical path loss is approaching, or has exceeded, the maximum allowed. On loss of input the optical LED
illuminates red.
On the IRT-6630-DDT, a green LED indicator on the front edge indicates presence of a laser, and turns red on
failure of the laser.
For path lengths <9dB optical loss when using an APD detector, or <3dB optical loss when using a PIN detector, an
optical attenuator is required. The length of fibre that this corresponds to depends on the fibre loss characteristics
at the relevant wavelength of the laser module chosen. For example, if the fibre loss characteristic of the chosen
fibre is 0.2dB per kilometre at 1550 nm, say, then the maximum distance that can be run is 135 km
(27dB/0.2dBkm), although connector losses, such as through patch lead connectors etc., should also be taken into
consideration when calculating maximum distances. Actual attenuation versus wavelength characteristics depends
upon optic fibre manufacturer’s own specifications. Also a few dB headroom is recommended to allow for the
effects of laser aging over time.
The output of the IRT-6630-DDR receiver is the same signal that was originally inputted to the opposite
IRT-6630-DDT transmitter. Front panel green LEDs indicate the presence of a valid locked 3 -SDI, HD-SDI, or an
SD-SDI type of output signal.
In the reclocker bypass mode, rates other than the 3 /HD/SD-SDI rates can be sent and received. If the data rate
does not match that of 3 -SDI, HD-SDI or SD-SDI all front edge signal data rate LED’s will flash to indicate that an
unknown data rate has been detected.

Page 13 of 28 Revision 01
Front Edge ED Indicators:
If the Transmitter (Tx) or Receiver (Rx) signal rate does not match the set
rate, the corresponding LED will flash. If a secondary signal is inputted to
the transmitter, its data rate LED will also flash regardless of whether it
matches the set rate or not.
In this example the IRT-6630-DDT transmitter has been set for either
HD/SD only or 3 /HD/SD operation. The primary input (IN 1) is being fed
with an HD source. The secondary input (IN 2) will flash indicating a
secondary input is present, in this case an HD signal. On loss of primary
input the secondary will take control and stop flashing if its rate is within
the set Tx rate.
If both primary and secondary inputs were HD-SDI signals, for example,
and the Tx data rate was set for SD only operation, then both the primary
(IN 1) and secondary (IN 2) HD LEDs will flash.
Laser failure on the IRT-6630-DDT is indicated by a red illuminated LASER
LED. In this example there is no laser failure as indicated by the green
illuminated LASER LED.
Optical present, optical low, and optical input failure, on the
IRT-6630-DDR is indicated by a bi-colour illuminated OPTICAL LED. In this
example the OPTICAL LED is flashing and is illuminated green, but so is
the received HD signal LED illuminated green. This indicates that an HD
signal is being received even though the OPTICAL alarm LED is illuminated
and flashing, thus the OPTICAL alarm LED is indicating that the optical
signal level is low, or approaching the minimum signal strength allowed
before signal failure takes place, whence the receiver output will be
muted. Note however that it is still possible for the optical signal strength
to be low and still allow an errored data signal to be received before
signal muting takes place. The optical low trigger point can vary between
the plug-in receivers, so if operating at signal paths close to the
recommended maximum specified threshold, signal analysis should be
performed to check the accuracy of the received signal if the OPTICAL
LED is flashing green.

Status TAB:
Status TAB shows the set input names corresponding to the received channel, this being set under the
Configuration TAB in the second half of the DashBoard™ frame (see next screenshot).
The received channel signal status and optical status is also shown. In this example, Channel 1, which corresponds
to the received signal, has a 270 Mb/s rated type of signal present, such as either SD-SDI or ASI; and the receiver
fitted to the IRT-6630-DDR is an APD type and its optical status is good. No I/O alarms are present and the card is
plugged into the correct rear assembly.

SNMP SOFTWARE CONTRO
Control via SNMP is possible via a third party Network Management System (NMS) provided the open ear® frame
is fitted with a relevant Network Management card. In the case of the O 3-FR frame the MFC-8322-NS network
management card is required for SNMP control. In the case of either the DFR-8310 or DFR-8321 frames either the
MFC-8310-NS or MFC-8320-NS cards are required for SNMP control. Relevant frame MIBs and card MIB required to
interface to NMS software - see I.R.T. Communications website (www.irtcommunications.com) for MIB download.
The MIB file for the IRT-6630-DDT and IRT-6630-DDR is a common MIB file for the family of IRT-6630 fibre links and
is named IRT-663x-Dxx. Not all parameters in the MIB file relate to these cards.
