Claim 0:
1. A non-destructive testing device, comprising:
a tubular housing including a proximal end and a distal end, the tubular housing including:
a head section arranged at the distal end; and
a bendable articulation section secured to the head section and arranged proximal to the head section; and

an optical sensor arranged within the head section, and the sensor configured to transmit a data set by at least differential signaling, the sensor including:
a first output terminal;
an output signal cable connected to the first output terminal and extending along the tubular housing to a control unit having a processor and circuitry, arranged at the proximal end of the tubular housing, wherein the output signal cable is configured to transmit a portion of the data set from the sensor to the control unit a first capacitor arranged in series with the output signal cable between the sensor and the control unit;
a second output terminal configured to be grounded to an insulation shield of the tubular housing; and
a second capacitor arranged between the second output terminal and insulation shield,
wherein the data set includes a first signal and a second signal, which is complementary to the first signal, and the output signal cable is configured to transmit only one of the first signal or second signal.
