J-Fiber Jena

Reliable and field-proven Singlemode optical fibers for LAN, FTTx, and long-distance applications

For LAN cabling applications with the need to bridge larger distances j-fiber provides a portfolio of reliable high performance Singlemode optical fibers. Our fibers are compatible with installed networks, offer enhanced bending features for robust, flexible use at lowest attenuation, while featuring perfect geometries with lowest fiber diameter tolerances to best meet LAN network system requirements.

We give FTTx the flexibility, cost-efficiency and future-safe perspective they demand. Our Singlemode fibers meet the robustness, compatibility and performance requirements of FTTx applications and represent the reliable choice in state-of-the-art Singlemode fiber technology.

For long-haul applications j-fiber Singlemode fibers provide the cost-advantages and performance reliability that high data-rate long-distance transmission demands.
