j-fiber - our products connect people worldwide
j-fiber GmbH is one of Europe’s leading providers of optical fibers for data transmission and the only industrial-scale manufacturer of fibers in Germany.
As a leading specialist for multimode fibers, j-fiber offers its customers a broad-based portfolio of services for standards-compliant, high-performance multimode fibers – from OM1 to OM5 multimode fibers. Our products facilitate the reliable transmission of data in modern data centers and manufacturing plants at rates of 1 gbps to 25 gbps, as well as future-proof cabling protocols running at up to 200 gbps. We offer our cable customers a variety of customer-specific services, including colors, ring marking, fiber setting and buffers, as well as FiberUnit products that help to drive productivity-optimized manufacturing methods.
In order to meet the rising demand for singlemode fibers for broadband expansion in Europe, in 2019, j-fiber formed the joint venture “j-fiber Hengtong GmbH” with the Hengtong Group and established new production capacities at its Jena facility for singlemode fibers “Made in Germany”.
There is a long history of optical fiber production in Jena. The development of preforms and optical fibers started well over 40 years ago at the “Jenaer Glaswerk. In 1994, these activities resulted in the spinning-off of an independent business: now known as j-fiber, this company is one of the world’s leading specialists for the multimode fibers used in modern data centers. In 2007, j-fiber became part of the LEONI Group, a global provider of products for energy and data management to the automotive sector and other industries.
