Product Description

G652D Low Water Peak Single-mode Fibre

GLFIBER®  low water peak dispersion unshifted Single-mode fibre is designed specially for optical transmission systems operating over the entire wavelength window from 1260 nm to 1625 nm. By suppressing the water peak that occurs near 1383 nm in conventional single mode fibre due to hydroxyl (OH-) ions absorption, GLFIBER® fibre is able to open E-band (1360-1460nm) for operation, and consequently provides 100 nm more usable wavelengths.

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

Key Configurations

(1) Comply to or superior to the ITU-T G.652D recommendation and IEC 60793-2-50 B1.3 specification.

(2) Designed for operation over 1260nm to 1625nm wavelength spectrum.(3) Outstanding optical performance supporting high-speed transmission requirement of DWDM and CWDM.

(4) Excellent PMD performance, supporting high-speed and long repeater spacing transmission system.

(5) Compatible with existing 1310nm equipment.
