Operational Safety: WARNING Operation of electronic equipment involves the use of voltages and currents that may be dangerous to human life. Note that under certain conditions dangerous potentials may exist in some circuits when power controls are in the OFF position. Maintenance personnel should observe all safety regulations. Do not make any adjustments inside equipment with power ON unless proper precautions are observed. All internal adjustments should only be made by suitably qualified personnel. All operational adjustments are available externally without the need for removing covers or use of extender cards.
Optical Safety The light emitted from the LASER diode used in this system is invisible and may be harmful to the human eye. Avoid looking directly into the fibre optic cable or connectors or into the collimated beam along their axis when the device is in operation. Operating the LASER diode outside of its maximum ratings may cause device failure or a safety hazard.

AVT-3070/xxx & AVR-3070/xxx Analogue Video Fibre Optic Link (/xxx = /APC or /PC) General Description The IRT AVT-3070 / AVR-3070 analogue video fibre optic link provides a channel bandwidth of 14 MHz allowing for a 6 MHz bandwidth video signal plus addition of several audio or data signals on subcarriers between 7 and 12 MHz. The video signal is handled directly by the AVT-3070 and AVR-3070 modules. Additional signals are added using a subcarrier mixing input on the AVT-3070 and are extracted from a subcarrier output on the AVR-3070. Separate modules are available to modulate and demodulate subcarrier signals for stereo audio and data. The use of fibre optic cable provides low signal attenuation with no gain or cable equalisation requirements and the added benefit of immunity to RFI and EMI and protection against lightning strikes. The system uses single mode fibre (9/125µm) operating in the 1300 nm window with an allowable path loss of up to 24 dB. The operating distance depends upon the actual cable and connector losses.
AVT-3070 LASER transmitter The AVT-3070 Transmitter uses a 1300 nm LASER diode with a launch power of between -7 and -10 dBm. The 6 MHz LPF can be by-passed to allow full use of the channel bandwidth of 14 MHz. A LASER power alarm and LED indicator are provided. If preferred, a 1500 nm LASER is available on request.
AVR-3070 PINTIA detector receiver This receiver contains of an PINTIA Diode detector, which allows for a 24 dB path loss. The detected optical signal is demodulated and the audio & data subcarriers split. The signal is then passed through a 6.0 MHz LPF to recover the base band video signal. Outputs are on the rear assembly of the module with a monitoring output on the front panel. Alarms and LED’s to indicate optical carrier failure and video failure are provided. Modules may be installed in an IRT 1 RU or 3 RU Eurocard frames. The modules may be categorised as follows:
Applications: • Single channel broadcast quality analogue video link. • Meets full broadcast CCIR or RS 250C Medium Haul Specifications up to a 24 dB optical path loss. • Audio & data channels can be carried above the video channel Fibre optic link benefits include: • Immunity from RFI. • Low signal attenuation. • Lightning immunity. • Electrical isolation eliminates ground loop problems. • Elimination of equalisers & amplifiers over the link path.

Technical Description A detailed circuit description is beyond the scope of this manual. The following description is intended to give the user only a basic understanding of the principles involved. If detailed information is required for servicing purposes, please contact the factory. Please refer to the diagrams provided at the rear of this manual as noted: AVT-3070: (dwg: 803801) The video input is equalised and amplified. Although the system is capable of a full 14 MHz bandwidth, frequencies above 5.5 MHz are not normally required for visual information. Frequencies above this are normally used for carrying supplementary signals by the use of subcarriers. In order to provide a clean signal for the inclusion of subcarriers, the video signal is passed through a low pass filter. The Faraday filter used is a plug in type and may be bypassed if full 14 MHz bandwidth is required for the video signal. Subcarriers for the audio channels are generated in separate modules for addition to the video signal. See separate manual for details. The video and the audio subcarriers are then pre-emphasised and back porch clamped. The resultant signal is used to modulate a wide band modulator, which has excellent linearity over the full modulation bandwidth. The modulator frequency, without deviation, is approximately 30 MHz. The modulated signal then drives the low powered LASER. The optical power output is set to -10 dBm and connected to the external fibre cable via an SC fibre optic connector. AVR-3070: (dwg: 804588) The optical signal received at the receiver is connected to a PINTIA diode. The signal detected by the photodiode is then amplified and fed to an AGC amplifier, which maintains a constant RF output level over the received optical signal range. The signal is then fed to a limiter and demodulator. The output from the discriminator is band limited to 14 MHz. It is then amplified and de-emphasised to provide a full bandwidth video signal containing both video signal and audio subcarriers. The video signal is split to provide a subcarrier output for de-modulation of audio and or data signals in their separate modules. The video signal is low pass filtered to remove any subcarriers and passed to the video output via the mute switch.

Configuration & Controls Operational Adjustments AVT-3070 Input Gain. The video input level has been factory aligned for a 1 Vp-p video signal at the input to the AVT-3070. The signal level to the AVT-3070 must be properly set for the video channel noise and linearity specifications to be met. Therefore if the video level into the AVT-3070 is different, the gain should be adjusted so that the VID. MON. output is 1 Vp-p. Cable Equalisation. If a long run of cable is used to feed the input to the transmitter then the EQ. should be adjusted to give a properly equalised video signal at the VIDEO MON. output on the AVT-3070. AVR-3070 Output Gain: The GAIN on the AVR-3070 front panel should be adjusted so that the video signal at the VIDEO MON. output is 1 Vp-p. AUDIO The AVT-3070 & AVR-3070 support the inclusion of audio or data signals on suitable subcarriers of the video signal. See separate manuals for details of these modulators and de-modulators.
Internal Adjustments The following adjustable controls are factory set and should not be adjusted. They are not 'operational' controls. Correct adjustment requires the use of calibrated standards and must be carried out in correct sequence. Any adjustment by the user is likely to, at best, degrade the performance and make the module incompatible with other modules or systems. The following list of controls is for information purposes ONLY as an aid to understanding the principles of the transmission system. Some controls and components are deliberately omitted from production units; provision for these on the PCB is for factory test purposes and custom configurations.

Installation 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.
Power: AC mains supply:
Ensure that operating voltage of unit and local supply voltage match and that correct rating fuse is installed for local supply.
DC supply:
Ensure that the correct polarity is observed and that DC supply voltage is maintained within the operating range specified.
Earthing: The earth path is dependent on the type of frame selected. In every case particular care should be taken to ensure that the frame is connected to earth for safety reasons. See frame manual for details. Signal earth: For safety reasons a connection is made between signal earth and chassis earth. No attempt should be made to break this connection.
Installation in frame or chassis: See also details in separate manual for selected frame type.
Warning Optical Connections The optical connectors on the AVT-3070 & AVR-3070 are attached 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.

Inter-module connections: See interconnection diagram following. Audio muting: The AAR-3140 dual audio de-modulator is provided with a muting input on PL 3, which may be used to mute the output audio when no video carrier is present. To enable this function PL 3 on the AAR-3140 must be connected to PL 4 on the AVR-3070. PL 4 on the AAR-3140 provides a loop through of this connection for use by another AAR-3140 where more than two channels of audio are fitted. Note: PL 3 & PL 4 on the AAT-3140 need not be connected and are included only for compatibility with previous systems. Subcarriers: (S/C in & S/C out) Audio and data signals that are required to be carried on the link are first modulated onto subcarrier frequencies between 6.5 MHz and 12 MHz. For actual subcarrier frequencies used, consult the manual for the appropriate modules. Each audio or data module provides a S/C out connection, which is adjusted to a suitable level for addition to the video signal. The S/C in connection on the AAT-3140 provides a means of adding subcarriers from other modules to those of the AAT-3140 so that only one S/C input is required on the AVT-3070. The converse connections apply at the receive end of the link with the AVR-3070 and AAR-3140’s. Connection of the subcarriers may be made using the accessory cable type GVW-3011 (150 mm BNC – BNC) where the modules are located side by side in a 3 RU frame or GVW-3012 (300 mm BNC – BNC) for 1 RU frames.
