15. Comcore Technologies’ Property Information www.comcore.com.cn 15 Product Features 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 coupler to protect the moisture enters these micro-cracks and proliferates them, causing coupler degradation and ultimate failure. 5. Improve polarization dependent loss. Superfusion TM Technology
