Optical Network Equipment
NTT-AT developed the world’s first self-retentive optical switch and realized the mechanism to retain optical signal transmission during power outages for the device in addition to the optical power observation function and the network paths instant switching function if a problem occurs. The switch is widely used by domestic and overseas Internet exchange companies as a robust optical switch. Furthermore, a reasonable port unit cost and a compact rack space are provided by a high-density design with 16 channels per 1 unit to satisfy cost-conscious customers.
