Classification of the products to be procured : 15, 2 Nature and quantity of the products to be purchased : Purchase of Satellite-to-Ground Optical Communications Modem Equipment, sets Type of the procurement : Purchase Basi requirements of the procurement : The equipment shall be installable within a 40cm optical ground station owned by NICT. Environmental conditions for installation will be specified in the specifications to be published at a later date For reception from an optical communications terminal installed on a satellite, the equipment shall connect via optical-fiber connectors or equivalent interfaces to a fine-acquisition and tracking receive optical system to be separately prepared by NICT. It shall convert the optical signal into an electrical signal, perform demodulation and decoding, and transmit payload data to an external network using the specified protocol and format. For transmission to an optical communications terminal installed on a satellite, the equipment shall connect via optical-fiber connectors to a high-power amplifier or a fine-acquisition and tracking transmit optical system to be separately prepared by NICT. It shall encode and modulate data received from an external network, convert the data into an optical signal, and transmit it The equipment shall support data communications using optical waves in the 1.5μm wavelength band between an optical communications terminal installed on a satellite orbiting at an altitude of approximately 50 to 1,000km with an orbital inclination of approximately 4 to 5 degrees, and an optical ground station installed in Japan The modem shall support bidirectional communications compliant with the requirements of "Optical Communications Terminal (OCT) Standard Version 3.1.0" established by the Space Development Agency (SDA) under the United States Department of the Air Force (hereinafter referred to as the "SDA OCT Standard") The proposer shall demonstrate that the modem can communicate bidirectionally with a spaceborne optical communications terminal that meets the requirements of SDA OCT Standard Version 3. or later and has flight heritage. Ground-based development or test models may be included. The proposer shall also demonstrate that a ground-based or satellite-to-ground communications test has been conducted, or is scheduled to be conducted, by the end of FY202 ⑦ Before installation at NICT optical ground stations, and no later than the end of FY2027, the supplier shall be able to provide the information and support required for compatibility testing with an engineering-model modem used for ground testing of a spaceborne modem. Such testing may include modem-to-modem data communications and protocol verification and is expected to be performed at a facility designated by NICT in Japan, assumed to be in the greater Tokyo area ⑧ In addition to the standard described in Item above, the equipment shall offer future extensibility toward standards proposed by the Consultative Committee for Space Data Systems (CCSDS) and standards such as ESTOL (ESA Specifications for Terabit/se Optical Links) proposed by the European Space Agency (ESA) ⑨ In satellite-to-ground optical communications, dee fading of the optical communications signal, of 10dB or more, is expected during low-elevation-angle segments, generally at 3 degrees or below. The modem developer, manufacturer, or supplier shall have researchers or engineers with suitable technical expertise who can communicate effectively with NICT personnel regarding technical countermeasures against such dee fading phenomena ⑩ The equipment shall provide functions for measuring and evaluating various aspects of optical communications quality during communication with a spaceborne optical communications terminal ⑪ To enable NICT to verify compliance with applicable Japanese laws and regulations, the supplier shall maintain a system for promptly consulting with NICT personnel after contract award if approvals, permits, notifications, or equivalent procedures are or may be required for the delivery of goods or facilities under the specifications, pursuant to the Radio Act (Act No. 13 of 1950), the Electrical Appliances and Materials Safety Act (Act No. 23 of 1961), and other applicable laws, regulations, and ordinances. In particular, for equipment containing high-frequency generating sections that constitutes high-frequency utilization equipment specified in the items of Article 100, paragraph of the Radio Act, or for equipment with radio communications functions using radio waves as specified in Article 4- of the Radio Act, including wireless LAN, mobile telephone, and radio-control functions subject to technical regulations conformity certification or equivalent certification under Chapter III- of the Radio Act (hereinafter referred to as "Giteki"), the supplier shall be able to submit evidence of certification. Such evidence may include, by the time of delivery, a photograph showing the Giteki mark on the equipment or the applicable certification number ⑫ To ensure information and communications security, the supplier shall submit in advance documentation concerning the equipment to be delivered, including an equipment list, a bill of materials or component configuration identifying products such as CPUs and memory devices, and a software configuration list, including an SBOM (Software Bill of Materials). If NICT determines that supply-chain risk concerns have not been adequately resolved, the supplier shall maintain a system for promptly and closely coordinating with NICT to revise the proposal, including selection of alternatives and implementation of risk-reduction measures Time limit for the submission of the requested material : 1 : 0 2 November 202 Contact point for the notice : Munemasa Yasushi, Space Communication Systems Laboratory, Wireless Networks Research Center, Network Research Institute, National Institute of Information and Communications Technology, 4-2- Nukuikitamachi Koganei-shi Tokyo 184-879 Japan TEL 042-327-649 E-mail munemasa@nict.go.jp
