- हां, मल्टी-कोर फाइबर एक अधिक उन्नत प्रयास है। वर्तमान में कुछ संबंधित अनुप्रयोग हैं, जो अभी मुख्यधारा में नहीं हैं, लेकिन अगली पीढ़ी में संभव होंगे।

    Recently, The research group of Fudan University has made an important breakthrough in the research of multi-core fiber fusion technology.

    In order to solve the problem of optical communication capacity expansion in the future, the accepted technical solution to improve single-fiber capacity is to use space division multiplexing technology. Multi-core fiber, multi-mode fiber or multi-core multi-mode fiber is the inevitable development trend of optical communication transmission.

Multicore fiber (MCF) share the same cladding compared to conventional single-core fiber. This high-density, multi-channel structure has advantages of low production cost, space saving, and high transmission capacity. Multi-core fiber has important application value in space division multiplexing optical communication system, data center connection, inter-chip communication, next generation fiber amplifier, optical sensing, quantum technology and so on.

    Multi-core fiber tapering technology is proposed by Fudan Team, including forward tapering and reverse tapering, which can be used to adjust the core spacing of multi-core fiber and control the mode characteristics of multi-core simultaneously.

    Based on the technology of reverse tapering of multi-core fiber, by matching the core spacing and mode field diameter of dissimilar multi-core fiber. The reaserch team can accurately prepare a core-spacing converter with low loss and low crosstalk for two types of multi-core fiber with mismatched core spacing.

Two isomorphic heterogeneous multi-core optical fibers are spliced together with converter respectively by Shinho S-12PM Fusion splicer.To get lower loss.
