Fujikura PANDA fibres are realised high dimensional symmetry and uniform round stress applying parts for polarisation maintaining.
Based on Fujikura's fibre technology, PANDA fibres are also realised low attentuation, low polarisation crosstalk and suitable designs for fusion-splice and optical connector.
Features:
Applications:
Low Loss
Low Polarisation Crosstalk
High reliability
Pigtail for LD and Modulator and any polarisation dependent devices
0.98μm and 1.48μm Pump LD stabiliser
PMD Compensator for High speed system
Sensing Fibre for Gyroscope and other applications
Structure of PANDA Fibre
Boron-doped SAP (Stress apllying parts) have higher thermal coefficient of expansion than the cladding
SAP: 3 X 10-6 / degree C
Cladding: 5 X 10-7 / degree C
The SAP shrinks more than the cladding during cooling process of drawing
Tensile strength of SAP direction remains in the core induces large stress birefringence
