Sapphire optical fiber Al2O3 single crystal transparent crystal cable Optical fiber communication line 25-500um

Short Description:

Sapphire is a chemical and scratch resistant material with a melting point of 2,072°C. MMI offers LHPG grade sapphire fibers from 25 to 500 μm in diameter. In addition, fibers are provided through a tapered extension end. This is an important feature because the flexibility of a fiber is inversely proportional to the 4th power of its diameter (for example, a 100 μm fiber is 16 times more flexible than a 200 μm fiber). Tapered fiber provides users with high throughput capabilities without sacrificing flexibility in energy transfer and spectral applications. PTFE sheathing and/or connectors can be used for fibers with diameters greater than 100 μm.
