Product Description

Single Mode Bare Optical Fiber G652D G657A1 G657A2 G655 Colored Optical Fiber 25.2km 50.4km 60km on Spool

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.

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
GL FIBER® Plus bending insensitive single mode fibre meets or exceeds the ITU-T Recommendation G.652.D/G.657.A1/G.657.A2/G.657.B2 including the IEC 60793-2-50 type B1.3/B6.a1/B6.a2/B6.b2 Optical Fibre Specification.
