Besides extending 2 telephone lines over the same fiber, these multiplexers also carry 1 Gigabit Autosensing Ethernet RJ-45 network port, which offers even more effective re-use of fiber cables. Even more importantly, – besides the extension, which more often than not, happens outdoors, AD-net’s Phone over Fiber extenders solves the problem of lighting protection for your home. Lengthy copper cables, installed outdoors, are prone to attracting lightning, and this can damage electrical equipment in your homes.
