Product Description

Optic Fiber Reel G657A2 G652D G657A1 Bare Colored Singlemode Transparent Invisible Optical Fiber Suppliers

GL FIBER® provides the whole series of SMF products that meet and even excel the requirements of standards on performance indicators. Due to the high stability, these products effectively meet the demand for high speed, large capacity, long distance and small bending radius necessary for signal transmission in different applications.

Specification

Applications

• All types of fibre cables with different structures
• High performance optical network operating in O-E-S-C-L band
• High speed optical routes for Fibre-to-the-Home networks
• Cables with extreme low bending requirements
• Small-sized fibre cable and optical component

Key Configurations

1. Extremely high bending loss resistance in the 7.5 to 15 mm bending radius range
2. Full compatibility with all G.652 fibres for any applications
3. Low attenuation satisfying the operation demand in O-E-S-C-L band
4. Low PMD satisfying high bit-rate and long distance transmission requirements
5. Low bending loss for highly demanding cable designs including ribbons
6. Accurate geometrical parameters that insure low splicing loss and high splicing efficiency
7. High nd-value satisfying long operational lifetime in minimum bend radius
