和文要約
英文要約Research in the following technical areas has been conducted to demonstrate the feasibility of a new opto-electric hybrid switching system for data center applications. The major accomplishments in FY2016 are as follows.
(1)A-1:Research of opto-electric hybrid switching system
Opto-electric hybrid switching system architecture was clarified and three optical switch architectures that can be extended to accommodate more than 1000 ports were proposed and evaluated. The feasibility of the architectures was proved by experiments.
(2)A-2:Research of specification of optical switch
Functional elements and specifications of optical devices for the architectures were studied and it was elucidated the major elements were common to the architectures.
(3)B-1:Research of control algorithm
Two types of flow control algorithm for optical/electrical switching, service-oriented method and data-oriented method, were studied and the advantage of the former method was revealed by proof-of-concept experiment.
(4)B-2:Research of switch hardware control interface
The control algorithm based on the service-oriented method was found to be adoptable to current switch hardware.
(5)C-1:Research of high speed wavelength switching technology
Wavelength switching time of a conventional wavelength tunable laser was examined experimentally and more than 80% of all wavelength combinations showed the switching time less than 100 microseconds.
(6)C-2:Research of wavelength-addressing type optical transceivers
Configuration of a wavelength-addressing type optical transceiver was clarified and burst mode 16QAM was selected as a modulation/demodulation format for the transceiver to realize the transmission up to 1Tb/s class. Experiments on existing modulators showed the feasibility of the target specifications required to the modulator for the transceiver.
(7)D:Research of spatial type optical switching modules
Using Silicon-on-Insulator (SOI) as a platform, several optical test circuits including splitters, waveguide crosses and 2x2 switch elements were designed and evaluated. The switching time of 55 microseconds which was fast enough to meet the requirements was confirmed.
(8)E:Research of high-density shuffle wiring
Silicon-dioxide single mode ribbon fibers and multi-fiber connectors were selected as the connecting device between shuffle modules and switching modules. Two types of shuffle module configuration to enable the orthogonality between space axis and wavelength axis were proposed.
(9)F:Study of International Standardization
Survey on the technologies relevant to international standardization in each technical field was started.
(10)G:Research and Development Promotion Committee
Meetings of Research and Development Promotion Committee were held for three times with participation of external experts.
