Furukawa Electric, its communications, Miharu Communications developed the solution which shifts the coaxial infrastructure of CATV to the optical fiber infrastructure. It is first time for CATV industry.

CATV has adopted HFC system in Japan.

As for the HFC system, many high-frequency amplifiers are embedded.It is for amplifying the spirit level of electrical signal.

Lots of UPS are also installed. It is for supplying the power, even if the electric current is cut off. Maintenance expense and electric expense are big burden.

A new solution arranges exclusive light receiver on FTTH transmit and employs it by AC100V feeding. It makes possible UPS remove.
