Can digital fiber optical repeater be used indoors and outdoors?

Yes, digital fiber optic repeaters can be used both indoors and outdoors for extending signal strength.  They are particularly useful for overcoming long distances where traditional copper cables would weaken the signal.

Here's a breakdown:

Indoor Use: Common in large buildings like offices, shopping malls, or hospitals where extending good signal strength across long distances is necessary.

Outdoor Use: Used in applications where cell towers are far away, such as rural areas, tunnels, or remote locations.  The fiber optic cable can carry the signal long distances without degradation, and the repeater then boosts it for better coverage in the desired outdoor area.

Things to Consider:

Weatherproofing: While some digital fiber optic repeaters might be suitable for both environments, outdoor models will typically have weatherproof casings to withstand rain, dust, and extreme temperatures.

Application: The specific type of repeater will depend on the signal you're trying to extend. There are repeaters for cellular signals, data signals, and even video signals.

If you're looking into a digital fiber optic repeater, it's best to consult with a professional installer or the manufacturer to ensure you get the right model for your specific needs and environment (indoor or outdoor).
