Proprietary CBT 7800914 Issue 10 2 CBT 7800000 Interrogator Unit (IU) System overview General Description The CBT 7800000 Interrogator Unit (IU) is available in two variants, intended for a variety of Distributed Fibre Sensing (DFS) applications. The QuantX is optimised for monitoring and protection of long linear assets and infrastructure, whereas the ODH-5X variant is optimised for seismic profiling, hydraulic fracture monitoring and flow monitoring in down-hole for fibres longer than 10 km. -
Page 7: Rear Panel
Proprietary CBT 7800914 Issue 10 switches are in the Laser Enable position (and the rear panel Interlock Port is enabled) the red “Laser” LED is illuminated. The “Power” LED shows the status of critical internal power supplies. The “Status” LED gives a high level indicator of the IU’s status – red indicating that the IU is in a state where normal data acquisition cannot take place or if persistent, a fault. -

Page 10: Laser Interlock
Proprietary CBT 7800914 Issue 10 2.2.4 Laser Interlock To enable Laser Emission the Front and Rear key-switches must be in the Laser Enable (vertical) position, and connection must be made between pins 1&2 and pins 3&4 of the laser interlock connector The laser interlock connector can be wired to a switch triggered by the opening of a door or enclosure such that when the door/enclosure is opened, the lasers will be automatically disabled. -
Page 11: Gps (Odh-5X As Standard; Option On Quantx)
Proprietary CBT 7800914 Issue 10 The IU is designed to operate on any fibre which is single-mode at 1550 nm. We recommend using fibres which are compliant with ITU T G.652 or equivalent (for example Corning® SMF 28®). For operation on other fibres, contact OptaSense for information on optimizing the configuration. -
Page 12: Installation
Proprietary CBT 7800914 Issue 10 3 Installation Handling The IU’s mass is 31 kg, therefore care must be taken when lifting: a two person lift may be required. Please consult your HSE function for guidance. Handles are located on the front and rear. These should be used for lifting or manoeuvring the IU. -

Page 20: Thermal Management
Proprietary CBT 7800914 Issue 10 Thermal Management The maximum operating ambient temperature (measured 25 mm in front of the Front Panel air intakes) is 50°C. The built-in Fan Module must be fitted and connected at all times. The installation location must allow air to enter the front panel intakes and to circulate freely around the Heatsink, and with clear space for the fan exhaust above the rear panel heatsink. -
Page 21: Laser Safety
Proprietary CBT 7800914 Issue 10 4 Laser safety The QuantX and ODH-5X IUs generate Class 3R invisible laser radiation. When correctly connected to an optical fibre, the emitted radiation is completely enclosed within the optical fibre cable, however, if the continuity of the optical fibre is broken (deliberately or accidentally) then Invisible Laser Radiation will become accessible. -
Page 22: Operation
Proprietary CBT 7800914 Issue 10 5 Operation Connection To operate the IU system, first connect the sense fibre, control ethernet cable, optical data cable and power as per Section 2.2. Trigger and GPS cables should also be connected where these functions are required. Start up Turn on the main power switch on the rear panel. -
Page 23: Modes Of Operation
Proprietary CBT 7800914 Issue 10 5.3.1 Modes of Operation The IU produces Quantitative phase and amplitude in all operating modes. Additionally, the user has the flexibility of operating in either “Single Carrier” or “Dual Carrier” mode. In Single Carrier mode a single pulse is launched, and the backscatter analyzed to produce the quantitative data set. - Page 24 Proprietary CBT 7800914 Issue 10 Figure 5-2 – Performance envelope graphs for 8 m Gauge Length for Dual Carrier operation.
