Single-mode bend resistant fiber
Make RequestDescription
Features
Characteristics
Intended for:
- application in fiber-optic sensors with small bending diameters of the optical fiber
- application in fiber-optic communication lines when laying optical fiber in splice cassettes
- working wavelength 1550 nm
- minimum bending diameter without increasing optical losses
- small optical losses on working wavelength
