GLASSES FOR OPTICAL FIBER

Application:
the developed glass is used for manufacturing of optical fiber which consists of optical fiber core, light-reflective and protective clad layers.
refractive index: optical fiber core – 1.8050
light-reflective clad layer– 1.4915 protective clad layer – 1.5060
temperature coefficient of linear expansion, К-1:
optical fiber core – 77.7∙10–7
light-reflective clad layer – 58∙10–7 protective clad layer – 63∙10–7
melting temperature, оС:
optical fiber core – 1,220
light-reflective clad layer – 1,550 protective clad layer – 1,450
Advantages:
high stability to crystallization; absence of harmful oxides (Class 1 danger type) in glass’s composition; meets the required optical, thermal and rheological parameters; good export potential for products based on optical fiber.
