FTTP ONT red light often indicates optical signal loss or fiber cable connection issues. By adopting the TIA/EIA‑598C standard, you gain a universal "language" of colors that speeds identification, reduces miswiring, and enhances safety across cable jackets, connectors, buffer tubes, and splice trays. There are six fundamental colors in the visible spectrum – These are red, orange, yellow, green, blue, and violet. A VFL is used to detect faults, breaks, or bends in fiber optic cables by emitting a bright red light that is visible even through the fiber's jacket. Here is what can be done:First, power cycle the NBNco connection box and Optus modem to reset the connection and potentially clear the red optical light.
