Since the off the shelf solutions I know of don't use optic cable I have to answer I haven't seen such a solution.
Maybe the usual https://www.wilsonamplifiers.com/ will do the job but if it must be optical then you need to see if they can do a custom.
Hi folks! I'm Riccardo,
i need to cover an indoor tunnel area with a GSM signal. I need to get the outdoor signal send it on optic cable fiber and radiate it into the cave, i need to use my mobile indoor.
Anyone can help me if it is possible?
Timing to set up network, devices and what kind of antenna to use...
I have no idea.
Tanks.
