New platform achieves top-level long-distance transmission capacity of 1.2 Tbps while delivering 60% reduction in CO2 emissions
Tokyo, February 22, 2023 – Fujitsu today announced the launch of its 1FINITY Ultra Optical System, a hyper-reliable optical transport platform delivering extreme performance and scalability with data rates of 1.2 terabits per second (Tbps) on a single wavelength, with future upgrade to 1.6 Tbps. Fujitsu will launch the new platform in the first half of 2023 to communications service providers (CSPs) and cloud infrastructure providers (CIPs) globally, starting with customers in Japan, North America, as well as throughout Europe where Fujitsu recently expanded availability of its full line of optical, wireless and networking software solutions.
The next generation system features a digital signal processor (DSP) using latest semiconductor processes and liquid cooling technology with twice the cooling capacity of conventional technology. It further utilizes latest technologies including Fujitsu’s continuous C+L ROADM architecture (1) able to handle multiple wavelength bands in a single product, as well as the optical signal amplification technology forward Raman amplification (2). These features allow the new system to reduce carbon emissions compared to similar platforms, while maintaining high data rates of 1.2 Tbps on a single wavelength and 40% greater reach than that of conventional systems.
This launch demonstrates how Fujitsu continues to contribute to the realization of a sustainable society by expanding resilient network infrastructure that can respond to the rapid increase in data traffic due to increased demand for IoT and big data processing, while simultaneously reducing power consumption and achieving a 60% reduction of CO2 emissions throughout networks.
Fujitsu will present the new system at its booth at MWC Barcelona in Spain from February 27 to March 2 and at OFC in San Diego from March 7 to March 9, 2023.
Features of the 1FINITY Ultra Optical System
The next-generation Fujitsu 1FINITY optical transport platform includes the T900 Series Transponder and L900 Series Optical Line System:
1. Contributing to customers’ reduction of CO2 emissions through large-capacity, long-distance communication with low power consumption
The T900 Series Transponder represents an optical transponder to deliver top-level data rates of 1.2 Tbps on a single wavelength. The newly developed high performance coherent DSP (3) and ultra-high-speed CDM (Coherent Driver Modulator) (4) enable 135 Gbaud (5) capabilities. The T900 Series Transponder further incorporates Fujitsu’s closed-loop liquid cooling technology (6) with twice the cooling capacity and half the acoustic noise of air-to-air systems.
The L900 Series Optical Line System features a continuous “C+L ROADM architecture” which enables an expansion of the communication capacity per optical fiber by handling the longer wavelength band of the L-band in addition to the C-band wavelength band commonly used in optical networks.
The system further features forward Raman amplification that can improve the reach and transmission capacity of optical signals by amplifying them on the transmission path.
These technologies will support customers in improving the scalability of their network infrastructure and will further contribute to the decarbonization of the entire optical network, as the system requires fewer transponders and decreases power consumption.
2. Support in building and operating resilient networks with flexible installation and simplified management
Conventional optical wavelength multiplexing devices required network operators to bundle multiple optical fiber cables within the device, resulting in high cable complexity and difficulties during installation. By adopting a smart fiber cable system (7) within its L900 Series Optical Line System, Fujitsu succeeded in reducing cabling complexity by more than 80%, and troubleshooting time during installation and commissioning from multiple hours to seconds. Customers can further choose to add an integrated dual-wave Optical Time Domain Reflectometer (OTDR) (8) to measure and analyze the state of optical fibers such as transmission conditions and disconnections and Pseudowave technology (9) to streamline network management and improve efficiency to the system.
Moving forward, Fujitsu plans to offer services using machine learning to optimize network operations and resources for use in combination with Fujitsu’s “Virtuora Network Control Solution” for wide-area network operation and management.
C+L ROADM architecture :
With respect to the wavelength range used for transmission, products were conventionally divided in C-band, L-band and wavelength band; Fujitsu’s new system can handle both wavelength bands at once, contributing to an increase in the maximum transmission capacity of the system.
Forward Raman amplification :
Technology developed by Furukawa Electric Co. Ltd., in which signal light and excitation light propagate in the same direction in an optical fiber, and the transmission distance is extended by Raman excitation of the signal light. Previously, the inclusion of noise components in communications represented a problem, but by newly adopting the secondary excitation Raman system, the influence of noise components on signal light is reduced.
