3. Different Cross-sectional Shapes in Different Process
Normal Process(stick)1000ºC
Comcore’s Process(Melting Process)
1700C
1000ºC is much far from the melting point of silica of fiber, so fibers cannot be truly fused or melt together, and this process is used by more than 95% of manufacturing vendors who make fused fiber components such as splitters / WDMs. But, Comcore uses special process which can totally fuse two fibers together, becoming more reliable, more stable, and against humility.

7. Features of FFPs by using Superfusion process:(1) The structure of coupling region is very strong, the cross-sectional
shape looks like a twin core fiber.(2) Optical characteristics of devices are , relatively speaking, insensitive
to surrounding environment.(3) Very small twisted effect due to almost circularly symmetric
structure of cross-section.(4) Eliminate micro-cracks on the surface of fibers included in non-coupling
and coupling region of FFP to protect the moisture enters thesemicro-cracks and proliferates them, causing FFP degradation and ultimate failure.
(5) Improve polarization dependent loss and wavelength isolation for WDMs.
