The Fujitsu 1FINITY™ Ultra Optical System is an optical transport platform with terabit speeds on a single wavelength, sustainable liquid cooling and AI/ML automation to optimize end-to-end service delivery. The next generation 1FINITY Ultra Optical System, which encompasses the T900 Series Transponder and L900 Series Open Optical Line System (OLS), offers an optical transponder that incorporates closed-loop liquid cooling--the 1FINITY T900 Series Transponder. This technology provides energy savings on two fronts: liquid cooling provides better heat transfer to maintain a lower operating temperature, and the system consumes less energy, reducing costs. Fujitsu claims the closed-loop liquid-cooled system in a compact modular chassis also offers much longer fan life because fans run much slower, delivering higher reliability and greater sustainability than air-cooled fans.
