Long cables inside an endoscope camera module intensify attenuation and reflection of high-speed differential signals within the thin wires, causing 720P (or higher) images to exhibit noise, color shifts, or frame drops. The added distributed capacitance and inductance also slow clock edges, producing stutter or ghosting in a 30 FPS stream and compromising the clinician’s or technician’s judgment.
Moreover, the integrated LED beads share the same slender cable for power; excessive length increases DC voltage drop, dimming the LEDs and forcing the sensor to raise its gain—amplifying noise. Longer wires also pick up more external electromagnetic interference, further degrading the low-light signal-to-noise ratio. Therefore, cable length must be kept within the manufacturer’s recommended 30 cm to preserve image quality and system stability.
