NTT contributes NOS for Disaggregated Coherent Transponders to TIP

NTT Electronics has contributed its Goldstone Network Operating Software for disaggregated coherent transponders to the Telecom Infra Project’s NOS Software Project, which is hosted by the Open Optical and Packet Transport project group.

Goldstone utilizes many existing open source components which have been developed in Open Compute Project and Telecom Infra Project, including Open Network Linux, SONiC, Switch Abstraction Interface, and Transponder Abstraction Interface. ONL is used as the base operating system and provides a wide range of open network device support. On top of ONL, Kubernetes is employed to enable containerized application management, which realizes flexible and modular software composition. SONiC/SAI is deployed as a fleet of containers when the target hardware comprises Ethernet switch ASIC, whereas TAI is used when the target hardware has coherent transponder components.

NTT said its Goldstone NOS leverages a modular architecture, enabling it to be extended to support networking devices, which don’t have an Ethernet ASIC, but may include conventional transponders, ROADMs or amplifiers in the future.

Goldstone was originally started as a prototype NOS for Edgecore’s Cassini Platform. The work has led to a production deployment by mixi in Japan, and more than five industry partners are evaluating Goldstone on the Cassini platform. It is also being incorporated in Wistron’s Galileo platform.

“As the first operator who deployed Goldstone in production, mixi welcomes the contribution of Goldstone by NTT Electronics to foster more collaboration among the open networking industry. Goldstone brought us huge flexibility and control over our DCI connectivity which is critical for our services” Tatsuma Murase, CTO, mixi, Inc.

“Edgecore is pleased to be working with NTT Electronics and the broader industry community to enable disaggregated solutions with open packet transponders that will provide broader optical technology choices for network operators.” George Tchaparian, President and CEO, Edgecore Networks.

NTT Electronics' portfolio includes coherent optics and digital signal processors (DSPs)

NTT improves GPS Time Synchronization

NTT and FURUNO ELECTRIC CO. have developed a receiver for GPS and other global navigation satellite systems (GNSS) that significantly improves time-synchronization accuracy in areas with severe reception conditions such as among buildings and in mountainous areas.

NTT said its new satellite signal selection algorithm and a time synchronization GNSS receiver from FURUNO makes it possible to use multi-path satellite signals (reflected or diffracted from buildings and other structures), which previously inhibited accuracy of time synchronization. In a real multi-path reception test environment, time error was reduced to approximately 1/5 of earlier values. This is a remarkable result in that it promises to enable time synchronization accuracy close to that obtained in open-sky reception environments with no obstructions, even in environments previously considered poor and unsuitable for accurate time synchronization, such as among buildings or in mountainous areas.

FURUNO plans to begin sales of their new GF-88 series time synchronization GNSS receivers incorporating this new technology in April of 2019. Potential applications include  4G/5G mobile base stations, financial trading, power grids, and data centers.

NTT and Tokyo Institute of Tech achieve 100 Gbps using terahertz band

NTT and Tokyo Institute of Technology have jointly developed an ultra high-speed IC for wireless front-end that operates on a terahertz frequency band, and in the 300 GHz band they have achieved a record 100 Gbps wireless transmission data rate.

The researchers implemented a mixer circuit that applied a unique proprietary high isolation design technology with an Indium phosphide high electron mobility transistor (InP-HEMT). NTT said this process enlarged the transmission bandwidth, which is a problem in the conventional 300 GHz band wireless front end. It also improved the signal-to-noise ratio (SNR). In addition, using this we realized a 300 GHz band wireless front-end module, and we achieved wireless transmission of 100 Gbps (gigabits per second).

NTT said future work will extend to multiple carriers by making use of the wide frequency band of 300 GHz band, and using spatial multiplexing technology such as MIMO and OAM. The researchers hope to produce an ultra high-speed IC that enables wireless transmission of 400 Gbos.

NTT employs Orbital Angular Momentum multiplexing for 100G wireless

NTT successfully demonstrated the first use of Orbital Angular Momentum (OAM) multiplexing to achieve 100 Gbps wireless transmission.

The laboratory tests combined OAM multiplexing with Multiple-Input Multiple-Output (MIMO) technology and carried the signals a distance of 10m.

NTT said a key feature of OAM is that electromagnetic waves can be superposed and separated because phase rotation occurs on the vertical plane in the propagation direction.  An electromagnetic wave with phase rotation cannot be received without a receiver having the same number of phase rotations at the time of transmission. NTT developed a transceiver operating in the 28 GHz band capable of OAM transmission. NTT also developed signal processing technology capable of handling 11 data signals simultaneously each at a bit rate of 7.2 to 10.8 Gbps, thereby achieving large-capacity wireless transmission at a total bit rate of 100 Gbps.

NTT believes the technology holds promise for achieving large-capacity wireless transmission at a level about 100 times that of LTE and Wi-Fi and about 5 times that of 5G.
