Fujikura has jointly developed the “TitaniaBend PANDA PM Fiber” with Corning Inc., a U.S. company, for next-generation optical transceivers capable of transmitting information at over 800 gigabits per second, and will begin shipping samples in fiscal year 2025.
The product uses an optical fiber design that achieves single-mode operation even at short lengths, and by providing a titanium-doped layer on the glass surface of the optical fiber, it achieves both optical properties and mechanical reliability in small-diameter bending environments.
It can also withstand severe bending conditions with a bending radius of 5 mm or less, reducing bending loss when a tight bend is applied by up to 90% compared to conventional products.
As AI applications rapidly increase, faster and larger-capacity optical communications are required, and in order to accommodate the increase in communication traffic, optical transceivers are being integrated and miniaturized. The polarization-maintaining optical fiber (PANDA Fiber) used in optical transceivers needs to be stored in a limited space, so a smaller allowable bending radius is required.
