Fujitsu serves up 150 GBaud enhancement for 1FINITY™ Ultra Optical System

March 21, 2024
The new version enables enhanced terabit speed reach for data center and metro optical applications.

Fujitsu Network Communications introduced 150 GBaud enhancements for the 1FINITY Ultra Optical System, offering scale and terabit performance for long-haul, metro, and data center interconnect (DCI) optical networks. 

The enhanced 1FINITY T900 Series Transponder, comprised of the 1FINITY T900 Series Transponder further extends the reach of 1.2 Tbps per wavelength transmission in high-speed DCI and metro optical networks.

Supporting 150 GBaud rate, in combination with a more robust forward error correction (FEC) algorithm, enables 800G wavelength transmissions to reach up to 30 percent farther in long-haul networks. Fujitsu claims that the 1FINITY T900 Series Transponder is the first platform to demonstrate 1.2 Tbps per wavelength transmitted over 336 km in a commercial network.

Besides providing performance improvements, the enhanced 1FINITY T900 Series Transponder helps communications service providers (CSPs) and cloud infrastructure providers (CIPs) realize cost savings. First, the higher baud rate means fewer transponders are needed compared to alternate solutions in the market, reducing overall transport infrastructure costs. Second, an energy-efficient design allows higher speeds without increasing power consumption per bit.

Rod Naphan, senior vice president and head of the photonics systems business unit at Fujitsu, said the “enhanced 150 GBaud functionality enables “greater speed, reach, and flexibility with lower total cost of ownership.”
