The efforts by both companies address one of the next commercial and technical hurdles for laser communications in space: proving that systems built by different companies can reliably connect.
SAN FRANCISCO, JAPAN, 6 JULY 2026: Transcelestial and Warpspace Inc. today announced a new partnership to jointly demonstrate interoperability for optical satellite communications, supporting the development of multi-vendor laser communications infrastructure across ground and space networks.
“This is a great partnership between Japan and Singapore. Space laser networks cannot scale as a series of isolated demonstrations. At some point, every serious mission has to answer a very basic question: can my system talk to yours, and can the data move securely from orbit to the ground without being trapped inside one architecture? This collaboration with Warpspace is about moving from compatibility claims to demonstrated interoperability. The real proof is in getting independently built systems to work together. That is what we are working toward, and it is a critical step toward the Earth-to-space internet we have been building from Day 1,” said Yuichiro Hikosaka, Head of Japan Sales; Global Head of Strategy and Investments at Transcelestial.
“Satellite operators are moving toward optical communications because they need to move more data from orbit, faster and more securely. But for optical networks to become commercial infrastructure, operators need confidence that terminals, relay systems and ground stations can work together across vendors,” said Hirokazu Mori, Group Chief Strategy Officer and CEO of USA at Warpspace.
Under the collaboration, Transcelestial and Warpspace will work on ground-based and space-based demonstrations designed to validate interoperability between independently developed optical communication systems.
For customers, the commercial value is direct: interoperable optical communications infrastructure can reduce integration risk, avoid vendor-locked architectures and support more resilient satellite network design. As demand grows for high-throughput, secure and low-latency data movement from orbit, operators need optical systems that can scale across ground-to-space, inter-satellite and hybrid network environments.
Laser communications offer significant advantages over traditional radio frequency systems, including higher data rates, improved security and reduced spectrum congestion. But broad adoption will depend not only on the performance of individual terminals, but on whether those systems can operate together in real-world mission environments.
By working together on interoperability demonstrations, Transcelestial and Warpspace aim to help move optical satellite communications from standalone capability toward scalable, multi-vendor infrastructure.

About Warpspace
Warpspace develops innovative solutions based on Japan’s expertise in free-space optical communications to meet the growing demand for satellite and spacecraft connectivity. As space activities expand and traditional radio frequency (RF) communications face increasing limitations, Warpspace is building technologies such as a virtual simulation platform for satellite constellation’s mission planning and validation, and a multi-standard optical modem “HOCSAI” that ensures interoperability between different protocols. Through these efforts, Warpspace aims to drive the seamless adoption and industrialization of optical communications in space.
About Transcelestial
Transcelestial aims to develop a constellation of LEO satellites as a true Undersea Cable replacement in space, allowing the laser network to not only connect inter-cities but upwards in space to connect all space assets.
Transcelestial has mass-produced a solution for superfast global Internet distribution that leverages its proprietary wireless laser communication technology to create a wireless distribution network between buildings, traditional cell towers, street-level poles and other physical infrastructure – with a much lower total operating cost for Mobile Network Operators, Internet Service Providers and enterprises.
Transcelestial has won numerous industry and global awards such as Fast Company’s Most Innovative, Most Frontier Company by Asiastar10x10, SPIFFY San Andreas Award for Most Disruptive Technology by Telecom Council, Forbes 30 Under 30 to their CTO Dr. Mohammad Danesh, Edge 35 Under 35 to their CEO Rohit Jha, The Most Ambitious Start-Up in Photonics Award by The Optical Society (OSA).
