4GHz Bandwidth RoF(Radio over Fiber) Module

Functional Description

    These RoF Module are used to analog optical transmission systems for mobile communication networks.


    The 4GHz broad bandwidth RoF Module is composed of one Donor module with several optical ports and one Remote module with one optical port. These modules was developed for DAS system to transmit and receive several kind of signal including 3GHz~4GHz for next 5G mobile communication network. 

It is designed to transmit and receive the signal of FWD/RVS with one optic fiber by using WDM. Donor module converts RF signal from BTS to optic signal and transmits it to Remote side. Remote module converts RF signal from terminal to optic signal and transmits it to Donor side. The conversion loss is compensated. The both side modules convert RF signal to optic signal and transmit it with one optic fiber. The method could minimize the transmission loss and noise level so that it is possible to transmit the signal to long distance.
