nApplications

 

The FTTH-YDS18B series optical terminal is a home-use optical receiver for FTTH (Fiber to the Home) network optical fiber access terminals to enable analog or digital signals to enter the home. The machine uses low-power photodetectors, GaAs and optical AGC technology to meet the fiber-to-the-home CATV reception needs.
