5.4um SM Fibercore 1250 (5.4/80) bending insensitive single mode fiber

5.4um SM Fibercore 1250 (5.4/80) bending insensitive single mode fiber

The 5.4μm SM Fibercore 1250 (5.4/80) is a premium bend-insensitive single mode optical fiber with a reduced cladding diameter of 80μm. Designed for high-reliability applications where space is limited and bending performance is critical, this specialty fiber offers outstanding optical performance across the 1310–1550nm telecom window while maintaining excellent bend loss characteristics.

Built with advanced Fibercore technology, the SM1250 (5.4/80) combines a 5.4μm core with a high numerical aperture design, delivering superior mode field control and mechanical robustness in a compact form factor. It is particularly suited for miniaturized optical components, fiber optic gyroscopes (FOG), and harsh environment sensing applications.
