Overview
NTT has developed an ultra-high-capacity (13.5 Tbits per second) long-haul (7,200 km) optical transmission technology to meet expected increases in data traffic. The capacity-distance product (an important measure of transmission capability) is the highest reported for this type of technology. The 13.5 Tbit/s capacity enables 135 channels of high-definition digital movies to be transmitted in one second. The signal multiplexes 135 channels (or wavelengths), each with capacity of 111 Gbit/s, and each channel can accommodate 100 GbE signal (next-generation Ethernet standard) reliably and efficiently. (T: Tera, 1012, G: Giga, 109)
