What voltage does a fiber optic router use

Fiber optic routers typically operate on low-voltage DC power, commonly 5V, 9V, or 12V, supplied via an AC-DC adapter from standard household or commercial AC power.Input VoltageFiber optic routers, like most modern routers, are powered through an AC-DC adapter that converts standard AC mains electricity into low-voltage DC. The AC input is usually 100–240V at 50/60Hz, allowing the router to be used worldwide without a voltage converter . In North America, this corresponds to 120V AC, while in many other countries, it is 220–240V AC . Industrial or specialized fiber routers may accept a wider DC input range, such as 9–36V DC, and some models can even handle 9–60V DC for direct connection to DC power sources .Output VoltageThe AC-DC adapter converts the high-voltage AC into low-voltage DC, which is what the router actually uses. Common output voltages for fiber optic routers are:5V DC (often for small or USB-powered routers)9V DC12V DC (e.g., 12V/1A or 12V/2A) The exact voltage and current rating are usually printed on the router or its power adapter and must match the router's specifications to avoid damage or instability .ConsiderationsHome routers generally use 5–12V DC and are designed for stable indoor AC power.Industrial fiber routers may support a wider DC range to accommodate variable power environments, such as transportation or remote monitoring setups .Using the wrong voltage can cause frequent disconnections, hardware damage, or reduced lifespan. Always use the original or manufacturer-recommended adapter. In summary, while fiber optic routers are specialized for high-speed internet, their voltage requirements are similar to standard routers, relying on low-voltage DC supplied via an AC-DC adapter, with typical values of 5V, 9V, or 12V DC depending on the model and application .
