  • What does the red light source of optical fiber mean

    What does the red light source of optical fiber mean

    A visual fault identifier or visual fault locator (VFI / VFL) is a visible red laser designed to inject visible light energy into a fiber. Sharp bends, breaks, faulty connectors and other faults will “leak” red light allowing technicians to visually spot the defects. The red light of a laser is coupled into the core of an optical fiber in a targeted manner (an LED is usually too weak a source to be used instead). It's a cost-effective and straightforward tool, making it ideal for quick troubleshooting and maintenance.


  • Optical module IN1 is lit by a red light

    Optical module IN1 is lit by a red light

    A green LED tells you that the board is powered, and a red LED will light up to let you know when the phototransistor is activated. Onboard we have a TCRT1000 right-angle sensor module. An advanced optical sensor featuring ambient light, RGB colour detection, and infrared sensing capabilities. Compatible with Arduino UNO R4 WiFi or any Qwiic-enabled. The LDR light sensor is very affordable, but it requires a resistor for wiring, which can make the setup more complex. The IR LED blasts light, and when something bounces the light back to the photo-transistor, the transistor turns on and the amount of current flowing through it increases. Photodetectors like these are critical components for projects ranging from line-following. The IR LED (Infrared Light Emitting Diode) manufactured by ARDUINO with part ID LED is a versatile component that emits light in the infrared spectrum, which is invisible to the human eye.
