There is really is no maximum or minimum distance when it comes to RFOF. RF signals can be transmitted over any length of fiber with the use of EDFA’s (Erbium Doped Fiber Amplifiers).
Consequently, the maximum benefit of fiber can be achieved using any fiber length. RFOF can be connected using a short fiber jumper and the optical signal can be amplified using EDFA on long fiber runs.
If needed, Global Foxcom staff can assist with your fiber design, to provide optimal performance at long distances.
