Hi,
Here are the advantages of ROF Technology :
Some of the advantages and benefits of the RoF technology are discussed follow:
(i) Low Attenuation Loss: Electrical distribution of high-frequency microwave signals
either in free space or through transmission lines is problematic and costly.

(ii) Large Bandwidth: Optical Fibers offer enormous bandwidth. There are three main
transmission windows, which offer low attenuation, namely the 850 nm, 1310 nm,
and 1550 nm wavelengths.
(iii)Immunity to Radio Frequency Interference: Immunity to Electromagnetic Interference
(EMI) is a very attractive property of optical Fiber communications, especially for
microwave transmission. Because of this immunity, fiber cables are preferred even
for short connections at mm-waves.
(iv)Easy Installation and Maintenance: In RoF systems, complex and expensive equipment
is kept at the head end, thereby making the RAUs simpler. For instance, most RoF
techniques eliminate the need for a LO and related equipment at the RAU.

(v) Multi-Operator and Multi-Service Operation: RoF offers system operational flexibility.
Depending on the microwave generation technique, the RoF distribution system can
be made signal-format transparent.
thanks,
