What IPT Fiber does
IPT Fiber, operating under the trade name 7Fiber, is a Polish specialty optical fiber manufacturer founded in 2019 as a subsidiary of InPhoTech Group and headquartered in Lublin/Lubartów, Poland. The company designs and manufactures advanced multicore, sidehole, and custom optical fibers, with proprietary products including the IPT-CORE 7-core multicore fiber, the SH1550 sidehole sensing fiber, customized preforms, and the IPT-FAN FanOut component. Its technology has demonstrated world-record transmission performance, achieving 11.2 Tb/s data rates with stated C-band potential up to 296.8 Tb/s, positioning IPT Fiber in the same next-generation specialty fiber category as Corning and Sumitomo.
The company is currently building the Advanced Optical Fiber Center (AOFC) in Lubartów, a purpose-built specialty fiber facility targeting 150,000 km/year production capacity with batch runs of up to 50 km per process — claimed as a world-first at that batch length. The project carries a total cost of approximately 110M PLN, of which around 74.7M PLN is non-dilutive EU grant funding. Go-to-market is direct B2B targeting telecom operators, network integrators, data centers, and sensing/IoT customers, with the patent portfolio granted or pending in 9+ jurisdictions serving as a primary commercial differentiator alongside performance benchmarks.
Revenue mechanics depend on direct sales of specialty fiber and component products under qualification-based cycles typical of telecom-grade optical components. The company currently lists approximately 5 employees, with the planned R&D center expected to scale headcount to 50+ once operational. Commercial references to date include partnerships with Orange Polska (a Tier-1 Polish telecom operator) and Infinera (a global optical networking systems vendor), alongside related-party demand from parent InPhoTech Group. Until the AOFC reaches commercial serial production, revenue is expected to remain at pilot/prototype scale, with unit economics dependent on qualification wins and capacity utilization at the new facility.
