Orange completes successful trial of Fujitsu 1FINITY optical transport solution

Fujitsu's 1FINITY T900 Series Transponder achieved successful lab evaluation by Orange S.A., demonstrating 800Gbps data transmission over 1600km with power consumption below 150 Watts. The trial highlighted the potential for increased long-haul transport distance and capacity without increased power consumption due to Fujitsu’s liquid cooling technology, addressing network operators' need for affordable and sustainable optical transport amid rising data demands and energy costs. Fujitsu is also establishing 1FINITY Inc. on July 1 to consolidate its network business.

Analysis

Orange S.A.'s successful lab evaluation of Fujitsu Limited's 1FINITY T900 Series Transponder marks a significant development in optical transport technology. The trial demonstrated the T900's capability to transmit data at 800 Gigabits per second (Gbps) over distances of at least 1600 km while maintaining power consumption below 150 Watts, a figure representing up to 70 percent less power consumption at 800Gbps wavelengths compared to traditional designs. This notable energy efficiency, attributed to Fujitsu’s unique closed-loop liquid cooling technology, directly addresses critical industry challenges for communications service providers (CSPs) like Orange, including escalating data demands, rising operational costs, and stringent environmental sustainability goals. The T900 transponder, which can support up to 1.2 terabits per second (Tbps) per wavelength, offers increased spectral efficiency, contributing to a lower overall cost per bit per kilometer and a reduced carbon footprint. This technological validation is strategically significant for Fujitsu, which reported consolidated revenues of 3.6 trillion yen for the fiscal year ended March 31, 2025, and is further underscored by its decision to consolidate its network business into a new entity, 1FINITY Inc., effective July 1, to enhance its global delivery of optical and wireless solutions.

Key Decisions for Investors

• Investors in Fujitsu Limited (6702) should recognize the successful T900 trial and the impending launch of 1FINITY Inc. as positive indicators for its competitive positioning in the high-demand, energy-efficient optical networking market; continued monitoring of T900 adoption and 1FINITY Inc.'s early performance is advisable.
• For Orange S.A. (ORAN), its proactive evaluation and potential adoption of such advanced, low-power network technologies signal a commitment to optimizing operational expenditure and bolstering its ESG credentials, which could be favorable for its long-term cost structure and sustainability profile.
• The demonstrated performance highlights a growing emphasis on energy efficiency within network infrastructure, suggesting that companies developing or deploying such sustainable technologies may present increasingly attractive investment opportunities, while CSPs effectively leveraging these advancements could achieve superior cost management.
